1、FEBRUARY|2024The Budget and Economic Outlook:2024 to 2034Projections at a GlanceThe Federal BudgetThe deficit totals$1.6trillion in fiscal year 2024,grows to$1.8trillion in 2025,and then returns to$1.6trillion by 2027.Thereafter,deficits steadily mount,reaching$2.6trillion in 2034.Measured in relati
2、on to gross domestic product(GDP),the deficit amounts to 5.6percent in 2024,grows to 6.1percent in 2025,and then shrinks to 5.2percent in 2027 and 2028.After 2028,deficits climb as a percentage of GDP,returning to 6.1percent in 2034.Since the Great Depression,deficits have exceeded that level only d
3、uring and shortly after World War II,the 20072009financial crisis,and the corona virus pandemic.Debt held by the public increases from 99percent of GDP at the end of 2024 to 116percent of GDPthe highest level ever recordedby the end of 2034.After 2034,debt would continue to grow if current laws gene
4、rally remained unchanged.Outlays in 2024amount to 23.1percent of GDP and stay close to that level through 2028.After 2028,growth in spending on programs for elderly people and rising net interest costs drive up outlays,which reach 24.1percent of GDP by 2034.Revenues amount to 17.5percent of GDP in 2
5、024,decline to 17.1percent in 2025,and then climb to 17.9percent of GDP by 2027after certain provisions of the 2017tax act expire.Revenues remain near that level through 2034.Changes in CBOs Budget Projections Since May2023The deficit for 2024 is$0.1trillion smaller than CBO projected in May 2023,an
6、d the cumulative deficit for the 20242033period is$1.4trillion(or 7percent)smaller.The biggest factor contributing to smaller projected deficits is a reduction in discretionary spend-ing stemming from the Fiscal Responsibility Act and the Further Continuing Appropriations and Other Extensions Act,20
7、24.The U.S.EconomyEconomic growth slows in 2024as unemployment increases,partly as a result of tight monetary policy.Real(inflation-adjusted)GDP growth accelerates in 2025after the Federal Reserve responds to weaker economic conditions in 2024by lowering interest rates.Interest rates rose in 2023as
8、the federal funds rate increased to its highest level since 2001.In CBOs projections,that rate begins to decline in the second quarter of calendar year 2024.Interest rates on 10-year Treasury notes rise in 2024 and then fall through 2026.Inflation(as measured by the price index for personal consumpt
9、ion expenditures)slowed markedly in 2023.In CBOs projections,it slows further in 2024to a rate roughly in line with the Federal Reserves long-run goal of 2percentand then ticks up in 2025,before declining slightly.Changes in CBOs Economic Projections Since February2023Growth of real GDP is weaker th
10、rough 2026,similar in 2027,and slightly stronger afterward.Interest rates are generally higher.From 2024 to 2027,those higher rates mostly reflect the effects of stronger-than-expected economic growth in 2023.In later years,higher rates are driven by more capital income and less private saving.The l
11、abor force is larger because net immigration,which began increasing in 2022,remains ele-vated through 2026.CBOs baseline budget and economic projections reflect the assumption that current laws governing taxes and spending will generally remain unchanged.Deficits and outlays have been adjusted to ex
12、clude the effects of shifts that occur in the timing of certain payments when the fiscal year begins on a weekend.Without those adjustments,the deficit projected for 2024 is$1.5 trillion(or 5.3 percent of GDP).www.cbo.gov/publication/59710By the NumbersThe Budget Outlook,by Fiscal YearSee Chapter 1.
13、When October 1(the first day of the fiscal year)falls on a weekend,certain payments that would have ordinarily been made on that day are instead made at the end of September and thus are shifted into the previous fiscal year.Outlays and deficits have been adjusted to remove the effects of those timi

24、out This ReportThe budget projections in this report include the effects of legislation enacted through January 3,2024,and are based on the Congressional Budget Offices economic projections.Those economic projections reflect economic developments and information as of December 5,2023,and are availab
25、le on CBOs website(www.cbo.gov/data/budget-economic-data#4).Unless this report indicates otherwise,all years referred to in describing the budget outlook are federal fiscal years,which run from October1 to September30 and are designated by the calendar year in which they end.Years referred to in des
26、cribing the economic outlook are calendar years.When October 1 falls on a weekend,certain payments that the government would have ordinarily made on that day are instead made at the end of September and thus are shifted into the previous fiscal year.Consequently,the number of payments in that previo
27、us fiscal year increases,and the number in the present fiscal year decreases.Those shifts in the timing of payments affect outlays and deficits(or surpluses)and thus are reflected in the agencys baseline budget projections(see Table 1-1).But timing shifts can complicate comparisons of annual outlays
28、 and deficits and distort cer-tain budgetary trends,so in many cases,CBO presents adjusted baseline projections that treat the payments as if they were not subject to the shifts(for examples,see Tables 1-2,1-4,1-6,and 1-9).Unless this report indicates otherwise,historical data shown in the text,tabl
29、es,and figures describing the economic forecast reflect data available from the Bureau of Economic Analysis and other sources in late January 2024.Those data contain values for the fourth quarter of 2023,which were not available when CBO developed its current projections.Numbers in the text,tables,a
30、nd figures may not add up to totals because of rounding.Some of the figures in this report use shaded vertical bars to indicate periods of recession.(A recession extends from the peak of a business cycle to its trough.)Previous editions of this report often included an appendix of historical budget
31、data.Those data and other supplemental data for this analysis are available on CBOs website(www.cbo.gov/publication/59710#data),as are a glossary of common budgetary and economic terms(www.cbo.gov/publication/42904),a description of how CBO develops its baseline budget projec-tions(www.cbo.gov/publi
32、cation/58916),a description of how CBO prepares its economic forecast(www.cbo.gov/publication/53537),and previous editions of this report(https:/ SummaryThe Congressional Budget Office regularly publishes reports presenting its baseline projections of what the federal budget and the economy would lo
33、ok like in the current year and over the next 10 years if laws governing taxes and spending generally remained unchanged.This report is the latest in that series.Projections for 2024Budget deficit:$1.6trillionDebt held by the public:99%of GDPOutlays:$6.5 trillionRevenues:$4.9 trillionThe Budget Outl
34、ookDeficitsIn CBOs projections,the federal budget deficit grows from$1.6 trillion in fiscal year 2024 to$2.6trillion in 2034.Deficits also expand in relation to the size of the economy,from 5.6percent of gross domestic product(GDP)in 2024,when the collection of certain postponed tax pay-ments tempor
35、arily boosts revenues,to 6.1 percent of GDP in 2025.In 2026 and 2027,reve-nues increase faster than outlays,causing the deficit to shrink to 5.2 percent of GDP by 2027.Thereafter,outlays rise faster than revenues.By 2034,the deficit returns to 6.1 percent of GDPsignificantly larger than the 3.7 perc
36、ent that deficits have averaged over the past 50 years.DebtDebt held by the public rises each year in relation to the size of the economy,reaching 116percent of GDP in 2034an amount greater than at any point in the nations history.From 2024 to 2034,increases in mandatory spending and interest costs
37、outpace declines in discretionary spending and growth in revenues and the economy,driving up debt.That trend persists,pushing federal debt to 172 percent of GDP in 2054.Outlays and RevenuesFederal outlays in 2024 total$6.5 trillion,which amounts to 23.1 percent of GDP.They stay close to that level t
38、hrough 2028 and then increase,reaching 24.1 percent of GDP by 2034.Growth in spending on programs that benefit elderly people and rising net interest costs drive those increases.Revenues in 2024 total$4.9 trillion,or 17.5 percent of GDP.They reach 17.9 percent of GDP in 2027,in part because of the e
39、xpiration of provisions of the 2017tax act,and remain near that level through 2034.Changes in CBOs Budget ProjectionsThe deficit for 2024 is$0.1 trillion(or 4 percent)smaller in CBOs current projections than it was in the agencys May 2023 projections,and the cumulative deficit over the 20242033 peri
40、od is smaller by$1.4 trillion(or 7 percent).The biggest factor contributing to smaller projected deficits over the 10-year period is a$2.3 trillion reduction in projected discretion-ary outlays stemming from the combination of the Fiscal Responsibility Act and the Further Continuing Appropriations a
41、nd Other Extensions Act,2024.Deficits and outlays have been adjusted to exclude the effects of shifts that occur in the timing of certain payments when the fiscal year begins on a weekend.Without those adjustments,the deficit projected for 2024 is$1.5 trillion(or 5.3 percent of GDP).2THE BUDGET AND

61、 year.In CBOs projections,economic growth rebounds in 2025 and then moderates in later years.A surge in immigration that began in 2022 continues through 2026,expanding the labor force and increasing economic output.Interest Rates Interest rates rose in 2023 as the federal funds rate(the rate financi
62、al institutions charge each other for overnight loans)increased to its highest level since 2001.In CBOs projec-tions,that rate begins to decline in the second quarter of 2024.Interest rates on 10-year Treasury notes rise in 2024 and then fall through 2026.Inflation Inflation slowed markedly in 2023.
63、In CBOs projections,inflation as measured by the price index for personal consumption expenditures(PCE)slows further in 2024,to a rate roughly in line with the Federal Reserves long-run goal of 2percent.It then ticks up in 2025,before declining slightly.Changes in CBOs Economic ProjectionsSince Febr
64、uary 2023,when CBO published its last full economic forecast,the agency has lowered its projections of economic growth and inflation(as measured by the PCE price index)for 2024.CBO also expects interest rates to be higher from 2024 to 2027 than it projected last year.After 2027,CBOs current and prev

78、 the easing of upward pressures on the prices of food,energy,and other goods.Another key reason is weaker growth in the prices of shelter services(which reflect the costs of both rental and owner-occupied housing)because of elevated interest rates in 2024.See Figure 2-5 on page 60.Outlook for 2024 2

82、ssional Budget Offices baseline budget projections,the federal budget deficit is$1.5trillion this year and generally increases over the next decade,reaching$2.6trillion in 2034.(If adjusted to exclude the effects of shifts that occur in the timing of certain payments when the first day of the fiscal
83、 year falls on a weekend,this years deficit would be$1.6 trillion.)The cumulative deficit is projected to total$20.0trillion over the 20252034period.Those projections,which were finalized on January3,2024,incorporate the effects of legislation enacted as of that date and therefore do not include the
84、 effects of any subsequent legislation,including the Further Additional Continuing Appropriations and Other Extensions Act,2024(Public Law118-35),which was enacted on January19,2024.1 Incorporating the budget-ary effects of subsequent legislation enacted to date would not significantly change the pr
85、ojections presented here.Measured relative to the size of the economy,the deficit equals 5.3percent of gross domestic product(GDP)in 2024.In CBOs projections,annual deficits generally increase over the 20252034period,averaging 5.7percent of GDP per year,well above the average deficit over the past 5
86、0years.As a result of those deficits,federal debt held by the public increases each year in CBOs projections,rising from 99percent of GDP this year to 116percent in 2034(see Table 1-1).That would be the largest amount ever recordedin U.S.history.The deficits in CBOs current projections are gener-all
87、y smaller than those in the agencys previous baseline projections for 2024 to 2033,which were published in May2023.The budget shortfall for 2024 is now pro-jected to be$63billion smallerand the cumulative deficit for the 20242033period,$1.4trillion lessthan CBO projected last May.Those net decreases
88、 stem from the Fiscal Responsibility Act(FRA,P.L.118-5)and the Further Continuing Appropriations and Other Extensions Act,2024(P.L.118-22),as well as updates to the agencys economic forecast and other changes(see Chapter3).1.Congressional Budget Office,cost estimate for H.R.2872,the Further Addition
89、al Continuing Appropriations and Other Extensions Act,2024(January17,2024),www.cbo.gov/publication/59893.After 2034,deficits continue to increase in relation to the size of the economy in CBOs projections.Outlays increase largely because of rising interest costs and growth in spending for the major
90、health care programs.Revenues also rise over the period,but more slowly than outlays.Such persistently large deficits cause federal debt held by the public,which has recently been at levels not reached since the end of World War II,to rise even further.CBO prepares its baseline budget projections in
91、 accor-dance with provisions set forth in the Balanced Budget and Emergency Deficit Control Act of 1985(the Deficit Control Act,P.L.99-177)and the Congressional Budget and Impoundment Control Act of 1974(P.L.93-344).Those laws require CBO to construct its baseline under the assumption that current l
92、aws governing revenues and spending will generally stay the same.For discretionary funding,CBOs baseline incorporates limits on such funding for 2024 and 2025,as specified in the FRA,and then reflects the assumption(as required by law)that funding will grow with inflation once those caps expire.Disc
93、retionary funding that is not constrained by the caps is generally assumed to increase with inflation throughout the next decade.CBOs baseline budget projections are meant to provide a benchmark that policymakers can use to assess the poten-tial effects of changes in policy.They are not intended to
94、provide a forecast of future budgetary outcomes,because future legislative action could lead to markedly different outcomes.Even if federal laws remained unaltered for the next decade,actual budgetary outcomes would probably differ from CBOs baseline projections,not only because of unanticipated eco
95、nomic conditions but also because of the many other factors that affect federal revenues and outlays,such as administrative actions.DeficitsThe projected$1.5trillion federal budget deficit for 2024 is$188billion less than the shortfall recorded last year.That deficit would be larger,and the decrease
96、 would be smaller,if not for a shift in the timing of certain payments in both 2024 and 2023.October1,2023(the first day of fiscal year 2024)fell on a weekend,so certain payments that would ordinarily have been made on that day were instead made in fiscal year 2023.Likewise,October1,2022,fell on a w

134、such deficits exceeded 2.0percent of GDP only three times.In the past 15years,though,they have exceeded that level 12timesin part because of legislation that was enacted in response to the 20072009financial crisis and the coronavirus pandemic that began in early 2020.The primary deficits in CBOs pro
135、jections are especially large given the relatively low unemployment rates that the agency is forecasting.From 2025 to 2034a period in which the average unemployment rate is projected to remain at or below 4.5percent in each yearprimary deficits in CBOs baseline projections average 2.1percent of GDP.
136、By way of historical contrast,from 1974 to 2023the unemployment rate was at or below 4.5per-cent in nineyears;in those years,the budget showed a primary deficit of 0.3percent of GDP,on average.DebtThe deficits projected in CBOs baseline would boost federal debt.That debt can be measured in various w
137、ays.The most common measure is debt held by the public,which consists mostly of securities that the Treasury issues to raise cash to fund the federal governments activities and to pay off its maturing liabilities.4 Other measures are used for different purposes,such as to pro-vide a more comprehensi
138、ve picture of the governments financial condition.Debt Held by the PublicAfter accounting for all the federal governments bor-rowing needs,CBO projects that debt held by the public would rise from$26.2trillion at the end of 2023 to$48.3trillion at the end of 2034(see Table 1-3).As a percentage of GD
139、P,that debt is projected to reach 116percent at the end of 2034about 19percentage points larger than it was at the end of 2023 and nearly two and a half times its average percentage over the past 50years(see Figure 1-2).The net amount that the Treasury borrows each year by issuing securities is dete
140、rmined primarily by the annual budget deficit.However,several other factors also affect 4.A small amount of debt held by the public is issued by other agencies,mainly the Tennessee Valley Authority.the governments need to borrow from the public.Those factorscollectively referred to as other means of
141、 financ-inginclude changes in the governments cash balances and cash flows associated with federal credit programs,such as those related to student loans and loans to small businesses.(Those cash flows are not reflected in the budget deficit,which accounts only for the subsidy costs of credit progra
142、msthat is,the estimated net lifetime costs of the programs loans and loan guarantees.)5 As a result of that additional borrowing,the increase in debt held by the public in 2024will exceed the deficit by about$150billion,CBO projects.Over the 20252034period,the increase in federal debt is projected t
143、o exceed the cumulative deficit by$387billion.The bulk of that additional borrowing stems from the need to finance federal loan programs.The cash dis-bursements needed to finance those programs each yearfor example,in the case of direct loans,the funds lent to borrowers minus the repayments of princ

145、ic minus financial assets excludes the value of the governments financial assets.That measure reflects the governments overall financial condition by accounting for the value of financial assets,such as student loans,that the government has acquired while incurring that debt.In CBOs baseline project
146、ions,that measure generally varies along with debt held by the public but is 6percent to 8percent smaller.Debt held by the public minus financial assets and debt held by the Federal Reserve excludes the value of financial assets held by the federal government as well as Treasury securities held by t
147、he Federal Reserve.That measure represents the net debt held by entities outside the government,which better reflects the governments overall effect on credit markets.In CBOs baseline projections,that measure increases 5.For more details about other means of financing and about federal debt more bro

158、ulated during the suspension will be added to the previous debt limit of$31.4 trillion.The Deficit Control Act requires CBO to project spending,revenues,and deficits independently of the debt limit.For more details,see Congressional Budget Office,Federal Debt and the Statutory Limit,February 2023(Fe
159、bruary 2023),www.cbo.gov/publication/58906.15CHAPTER1:THE BUDGET OUTLOOK THE BUDGET AND ECONOMIC OUTLOOK:2024 TO 2034from$19.1trillion(or 71percent of GDP)at the end of 2023 to$36.3trillion(or 87percent of GDP)at the end of 2034.(The Federal Reserves holdings of Treasury securities,which totaled$5.0
160、trillion at the end of 2023,are projected to fall to$4.4trillion at the end of 2024;thereafter,those holdings increase in CBOs projections,rising to$9.3trillion in 2034.)Gross debt consists of debt held by the public and Treasury securities held by government accounts(for example,the Social Security
161、 trust funds).The debt held by government accounts does not directly affect the economy and has no net effect on the budget.It is not a meaningful benchmark for Treasurys future obligations because it represents the cumulative difference between a programs past collections and expenditures.Although
162、debt held by the public increases by$22.1trillion from the end of 2023 to the end of 2034in CBOs baseline projections,debt held by government accounts falls by about$660billion,reflecting declines in the balances of many trust funds.As a result,gross federal debt is projected to rise by$21.4trillion
163、 over that period and to total$54.4trillion at the end of 2034.About 11percent of that sum would be debt held by government accounts.Debt subject to limit is the amount of debt that is subject to the statutory limit on federal borrowing,which is often referred to as the debt ceiling.Such debt differ
164、s from gross federal debt mainly in that it excludes debt issued by the Federal Financing Bank and includes certain other adjustments that are excluded from gross debt.6 Currently,the statutory limit on the issuance of new federal debt is suspended through January1,2025.In the absence of any legisla
165、tive action to adjust the debt limit before the suspension ends,the amount of borrowing accumulated during the suspension will be added to the previous debt limit of$31.4trillion.The Deficit Control Act requires that CBO project spending,revenues,and deficits independently of the debt limit.Thus,in
166、CBOs baseline projections,debt subject to limit continues rising over the next decade and reaches$54.5trillion in 2034.6.The Federal Financing Bank,a government corporation under the general supervision of the Treasury,assists federal agencies in managing their borrowing and lending programs.It can
167、issue up to$15billion of its own debt securities;that amount does not count against the debt limit.Figure 1-2.Federal Debt Held by the PublicPercentage of GDP Projected040801201602001900192519501975200020252050Data source:Congressional Budget Office.See www.cbo.gov/publication/59710#data.GDP=gross d
168、omestic product.Federal debt held by the public increases each year in CBOs projections,swelling to an all-time record of 116 percent of GDP in 2034.In the two decades that follow,growing deficits are projected to cause federal debt to soar to 172percent of GDP by 2054.16THE BUDGET AND ECONOMIC OUTL
169、OOK:2024 TO 2034 FEBRUARy 2024OutlaysIn CBOs baseline projections,outlays rise from 22.7percent of GDP in 2023 to 23.1percent in 2024 and remain near that level through 2028.Thereafter,outlays increase in each year as a share of the economy,reaching 24.1percent of GDP in 2034.Since 1974,outlays have
170、 averaged 21.0percent ofGDP.Outlays in 2024Federal outlays are projected to total$6.5trillion in 2024an increase of$0.4trillion(or 6percent)from the amount recorded in 2023.(If the budgetary effects related to the Administrations plan for student loan cancellations were excluded from last years tota
171、l,the projected increase in outlays would instead be 1percent.)In nominal terms,projected outlays rise this year in all three spending categoriesmandatory,discretionary,and net outlays for interestbut net outlays for interest and mandatory spending make up 96percent of the total increase.Mandatory S
172、pending.This category includes outlays for most federal benefit programs and for certain other pay-ments to people,businesses,nonprofit institutions,and state and local governments.Such outlays are generally governed by statutory criteria and are not normally con-strained by the annual appropriation
173、 process.7 Certain types of payments that federal agencies receive from the public and from other government agencies(such as premiums paid by Medicare beneficiaries and payments made by federal agencies to employees retirement plans)are classified as offsetting receipts and are accounted for in the
174、 budget as reductions in mandatory spending.The Deficit Control Act requires CBO to construct its baseline projections for most existing mandatory spending under the assumption that current laws generally remain in place.Therefore,CBOs baseline projections of man-datory spending reflect the estimate
175、d effects of changes in the economy,growth in the number of beneficiaries of certain mandatory programs,and other factors related to the costs of those programs.The projections also incor-porate a set of across-the-board reductions in budgetary 7.Each year,some mandatory programs are modified by pro
176、visions in annual appropriation acts.Such changes may increase or decrease spending for the affected programs for one or more years.In addition,spending for some mandatory programs(such as Medicaid and the Supplemental Nutrition Assistance Program)is considered mandatory,but benefits are paid from a
177、mounts provided in appropriation acts.resources(known as sequestration)that are required under current law for some mandatory programs.In 2024,CBO estimates,total mandatory outlays(net of offsetting receipts)will amount to$3.9trillion under current law,$166billion(or 4percent)more than they were in
178、2023(see Table 1-4).Those outlays are projected to amount to 13.9percent of GDP this yearequal to last years percentage but still well above the 11.0percent of GDP they averaged from 1974 to 2023.If the budget-ary effects of the Administrations plan for student loan cancellations were excluded from
179、2023totals,projected mandatory outlays this year would be$167billion less than they were in 2023.Outlays for these programs decrease the most in 2024in CBOs projections:Deposit insurance.Outlays of the Federal Deposit Insurance Corporation(FDIC)are projected to fall by$117billion this year as that a
180、gency continues to resolve the bank failures that occurred in 2023.This year(and over the next few years),the FDIC expects to recover much of what it spent to resolve those failures by liquidating the banks assets and collecting higher premiums from FDIC-insured institutions.CBO projects a reduced r
181、isk of bank failures in 2024relative to last years activity.Medicaid.CBOs updated baseline projections include a$58billion(or 9percent)drop in Medicaid outlays from 2023 to 2024.Two factors account for most of the reduction.First,states are continuing to reassess the eligibility of Medicaid enrollee
182、s who remained in the program during the coronavirus public health emergency.8 The Consolidated Appropriations Act,2023(P.L.117-328),ended the continuous-enrollment requirement on March31,2023,and states began to review enrollees eligibility and to disenroll those who no longer qualified.CBO expects
183、 Medicaid enrollment to fall in 2024as states continue that process.In addition,that law lowered the enhanced matching rate for federal reimbursement to states for Medicaid services from an average of 5percentage points in 2023 to 1.5percentage points 8.Provisions of the Families First Coronavirus R
184、esponse Act(P.L.116-127)required states to keep all Medicaid enrollees in the program until the coronavirus public health emergency ended.The declaration lifting that emergency took effect on May11,2023.17CHAPTER1:THE BUDGET OUTLOOK THE BUDGET AND ECONOMIC OUTLOOK:2024 TO 2034in the first quarter of
185、 2024 and to zero thereafter,which decreases outlays for the program.Pension Benefit Guaranty Corporation.Net outlays for the Pension Benefit Guaranty Corporation(PBGC)are projected to decline by$32billion(or 80percent)in 2024,to$8billion.That decrease stems almost entirely from less spending for PB
186、GCs special financial assistance program,which makes onetime payments to financially troubled multiemployer pension plans that qualify for assistance.Refundable tax credits.Outlays for refundable tax credits total$118billion in 2024in CBOs projections,$26billion less than the amount recorded in 2023
187、.Outlays for the coronavirus refundable tax credits decline by$31billion in 2024.9 In the opposite direction,outlays for the earned income tax credit are projected to increase by$7billion this year because of higher wages and employment gains.Supplemental Nutrition Assistance Program.Outlays for the
188、 Supplemental Nutrition Assistance Program(SNAP)are projected to fall by$23billion(or 17percent)in 2024,to$112billion.That decrease largely stems from the end of pandemic-related benefits.Emergency allotments that were provided to SNAP participants during the pandemic ended in February2023,and CBO p
189、rojects that spending for the Pandemic Electronic Benefit Transfer Program,which provided food benefits to households with children,will end in 2024.Additionally,CBO projects that SNAP participation will decline by about 1million people this year,to 41.1million.The largest increases in estimated out
190、lays for 2024 are for these programs:Higher education.In CBOs baseline,projected outlays for higher education increase by$213billion this year,rising to$29billion from$183billion last year.In 2023,the Administration recorded a net reduction of$207billion in the costs of outstanding loansprimarily re
191、flecting the$333billion reduction in outlays that resulted from the Supreme Courts decision 9.The coronavirus refundable tax credits are a group of tax credits to help employers cover the costs of sick and family leave,employee retention,and continuation of health insurance for certain workers durin
192、g 2020 and 2021.Employers may continue to claim those temporary tax credits on their amended tax returns;CBO projects that those claims will decline over time.that blocked implementation of the Administrations plan to cancel outstanding student loans for many borrowers.About one-third of the$333bill
193、ion reduction was offset by increased outlays recorded for the new income-driven repayment plan implemented by the Administration($74billion)and for other modifications the Administration made to the terms of outstanding loans and to changes in the underlying assumptions about the costs of those loa
194、ns($52billion).Excluding those 2023revisions to the costs of outstanding loans,spending for higher education would have increased by$5billion from 2023 to 2024.Social Security.Outlays for Social Security are estimated to increase by$104billion(or 8percent)in 2024,to$1.5trillion.About$80billion of th
195、at growth stems from an increase in average benefits,most of which was driven by the 8.7percent cost-of-living adjustment(COLA)in January2023 and the 3.2percent COLA in January2024.A net increase in the total number of beneficiaries accounts for the remaining growth.Most of the projected increase in
196、 outlays$98billionis for the Old-Age and Survivors Insurance portion of Social Security.The rest is for the Disability Insurance portion of the program.Medicare.Outlays for Medicare(net of offsetting receipts)reach$896billion this year in CBOs projections,$65billion(or 8percent)more than in 2023.Tha
197、t increase is the net result of a$76billion increase in spending for benefits and a$12billion increase in offsetting receipts(mainly from the collection of premiums).The growth in Medicare benefit spending is mostly concentrated in larger payments to Medicare Advantage plans(which allow beneficiarie
198、s to receive their Medicare coverage through private plans)and to Part D plans(which cover outpatient prescription drugs).Projected growth in payments for the traditional Medicare fee-for-service program is slower this year because of continued growth in Medicare Advantage enrollment:CBO expects tot
199、al Medicare enrollment to increase by 1million in 2024,which reflects an increase of 2million in enrollment in Medicare Advantage and a decrease of 1million in enrollment in Medicare fee-for-service.Veterans programs.In CBOs projections,mandatory outlays for veterans programs increase by$27billion(o
200、r 16percent)in 2024,to$195billion.Most of that increase stems from growth in the amount of disability compensation payments that some veterans receive.(Average disability ratings 18THE BUDGET AND ECONOMIC OUTLOOK:2024 TO 2034 FEBRUARy 2024Table 1-4.CBOs Baseline Projections of Mandatory Outlays,Adju

223、 result of the COLAs that went into effect in January2023 and 20248.7percent and 3.2percent,respectively.Taken together,outlays for all other mandatory pro-gramsincluding federal retirement programs and subsi-dies for health insuranceare estimated to rise,on net,by$13billion(or 0.3percent)in 2024.Di
224、scretionary Spending.This category encompasses spending for an array of federal activities that are funded through or controlled by appropriations.Discretionary spending includes most defense spending;spending for many nondefense activities,such as elementary and secondary education,housing assistan
225、ce,international affairs,and the administration of justice;and outlays for certain transportation programs(though funding for those programs is mandatory).In any year,some discre-tionary outlays arise from budget authority provided in the same year,and some arise from appropriations made in previous
226、 years.10In CBOs projections,discretionary funding and discre-tionary outlays each total$1.7trillion this year.Relative to amounts provided last year,this years funding is lower,but outlays are projected to be$17billion more.The agency projects outlays to increase this year despite the reduction in
227、budget authority primarily because of spending from budget authority provided in previous years.CBOs baseline projections of discretionary spending reflect laws that were in place as of January3,2024.The continuing resolution then in effect(the Further Continuing Appropriations and Other Extensions
228、Act,2024)provided funding through January19 for some federal agencies and through February2 for the rest.CBOs baseline incorporates the funding provided by that continuing resolution on an annualized basisthat is,calculated as if the funding provided by the con-tinuing resolution was in effect for t
229、he entire fiscal year.Because the resulting amounts exceed the limits on 10.Budget authority,or funding,is the authority provided by federal law to incur financial obligations that will result in immediate or future outlays of federal government funds.discretionary funding for 2024established by the
230、 Fiscal Responsibility Act,the total amount of budget authority and the resulting outlays have been adjusted to comply with those limits,or caps.(See Box 1-1 for details about the FRAs effects on CBOs baseline projections of discre-tionary spending.)Some discretionary funding in CBOs baseline is not
231、 constrained by the limits set in the FRA.Current law allows adjustments to be made to the caps for certain funding designated as an emergency requirement or(within statutory limits)for disaster relief activities,some efforts to reduce overpayments in benefit programs,and wildfire suppression.Other
232、funding is exempt from the caps altogether.Specifically,certain funding provided pursuant to the 21st Century Cures Act(P.L.114-255),funding derived from the Harbor Maintenance Trust Fund,and emergency funding covered by section 103 of the FRA does not count toward the caps.11 Funding that does not
233、fall into any of those categories(and is therefore constrained by the caps)is referred to as“base”funding.In CBOs baseline projections,discretionary budget authority for 2024 is$122billion(or 7percent)less than the amount provided in 2023(see Table 1-5).(Budget authority does not include obligation
234、limitations that govern discretionary spending for certain transpor-tation programs whose spending authority is manda-tory;the limitations are the same under the continuing resolution this year as they were last year.)12 The amount of base funding in CBOs baseline is$1.6trillion in 2024,generally re
235、flecting the limits set in section 102 of the FRA.13(Total base funding for 2024in CBOs baseline differs from the funding reported in CBOs cost estimate for the continuing resolution by$37billion.11.Funding covered by section 103 of the FRA stems from division J of the Infrastructure Investment and
236、Jobs Act,division B of the Bipartisan Safer Communities Act,and section 443 of division G of the Consolidated Appropriations Act,2023(which permanently appropriates as an emergency requirement funds collected by the Hazardous Substance Superfund).12.An obligation limitation is a restrictiontypically
237、 included in an appropriation acton the amount,purpose,or period of availability of spending authority.The limitation often affects budget authority that has been provided in an authorization act.Although the budget authority for many transportation programs is mandatory,the outlays from the obligat
238、ion limitations for those programs are considered discretionary.13.Although some funding is not constrained by the caps,that funding could be reduced under statutory procedures used to enforce the caps.21CHAPTER1:THE BUDGET OUTLOOK THE BUDGET AND ECONOMIC OUTLOOK:2024 TO 2034For an explanation,see B
239、ox 1-2 on page 24.)Budget authority that is not constrained by the caps totals$127billion this year.More than half of that amount was provided by the Infrastructure Investment and Jobs Act(P.L.117-58)and the Bipartisan Safer Communities Act(P.L.117-159),both of which were enacted in 2022.Discretiona
240、ry budget authority for defense totals$850billion in 2024,a$42billionor 5percentreduction from the amount provided in 2023.Last year,$33billion in funding designated as an emergency requirement was provided,mostly for military assistance to Ukraine.As of January3,2024,no such funding had been provid
241、ed for 2024.The reduction in base funding,which stems from the cap on defense funding,accounts for the rest of the difference.Outlays for defense are pro-jected to be$822billion in 2024,which is$17billion(or 2percent)more than such outlays were in 2023.From 2023 to 2024,total funding for nondefense
242、discretionary programs decreases by$81billionor 8percentin CBOs projections,to$876billion.Nondefense base funding accounts for$40billion of that reduction,driven largely by the cap on such fund-ing.In addition,funding designated as an emergency requirement that results in an upward adjustment to the

250、DGET AND ECONOMIC OUTLOOK:2024 TO 2034 FEBRUARy 2024Box 1-1.How the Fiscal Responsibility Act Affects CBOs Baseline Projections of Discretionary FundingTwo separate sections of the Fiscal Responsibility Act of 2023(FRA,Public Law118-5)established differing limitsalso known as capson both defense dis
251、cretionary funding and nondefense discretionary funding for 2024 and 2025.Which section of the law applies depends on the timing of the enactment of appropriations and the duration of funding.1 Caps established by section 101 of the FRA apply at the start of each fiscal year.But if a continuing reso
252、lution is still in effect on January1 of that same fiscal year,those caps will be replaced by the limits established in section 102 of the FRA.(If full-year appropriations are enacted after January1,the limits will revert to the caps under section 101 of the law.)The caps on defense and nondefense f
253、unding limit mostbut not alldiscretionary funding.Some funding designated for certain purposes causes an adjustment to the caps,and certain other funding is not subject to the caps at all.Because amounts appropriated for those purposes are generally not constrained by the caps,the Congressional Budg
254、et Office projects such funding in accordance with the provisions of the Balanced Budget and Emergency Deficit Control Act of 1985that is,by assuming that appropriations in future years are equal to the amounts provided for the current year with increases for inflation.(Funding for certain types of
255、activities that result in adjustments to the caps is subject to separate caps.)CBOs baseline includes downward adjustments to projected discretionary funding to reflect the effects of the caps.For 2024,because a continuing resolution was in place on January1,the baseline reflects the caps under sect
256、ion 102 of the FRA,which are$850billion for defense funding and$736billion for nondefense funding.Those amounts are below the amounts CBO estimated in its cost estimate for the continuing resolution underlying the projections in this report 1.For more information,see Congressional Budget Office,lett
257、er to the Honorable Jodey Arrington and the Honorable Brendan Boyle regarding implementing the statutory limits on discretionary funding for fiscal year 2024(January 4,2024),www.cbo.gov/publication/59861.by$10billion and$41billion,respectively.2 Because cost esti-mates for appropriation legislationn
258、ot the baselineare used when enforcing the caps,CBOs baseline reflects downward adjustments of those amounts in 2024(see the table).(Differ-ences between funding projected in the baseline and funding reported in the cost estimate for the continuing resolution cause total base fundingthat is,funding
259、constrained by the capsin the baseline to exceed the caps.)3For 2025,CBOs baseline reflects the caps established under section 101 of the FRA,which are$895billion for defense funding(an increase from the cap now in effect for 2024)and$711billion for nondefense funding(a decrease from the 2024cap now
260、 in effect).Because the amount of base funding projected for defense in 2025 is below the cap,no additional adjustments to projections of that funding in 2025 are required;base defense funding for 2025 and beyond is therefore projected by carrying forward the base funding for 2024,with adjustments f
261、or inflation.Thus,base defense funding in the baseline over the next several years is$10billion to$11billion less than the amounts that would be projected without account-ing for the caps.Projected base funding for nondefense activities exceeds the section 101cap by$100billion in 2025,in CBOs estima
262、tion,so the agency has included reductions of that amount to bring such funding in the baseline into compliance with the 2025cap.Thus,projected base funding in the baseline matches the cap in 2025$711billionand the baseline incorporates the assump-tion that base nondefense funding will equal that am
263、ount(with increases for inflation)in each year from 2026 through 2034.If not for the caps,beginning in 2025,base nondefense funding would exceed amounts projected in CBOs baseline by more than$100billion each year.2.Congressional Budget Office,cost estimate for H.R.6363,the Further Continuing Approp

269、ncy requirement or for disaster relief,certain program integrity activities,certain fire suppression operations,certain funding derived from the Harbor Maintenance Trust Fund,and certain programs designated in the 21st Century Cures Act.The amount of budget authority in CBOs baseline that is constra
270、ined by the caps does not match the level of the caps in 2024 because cost estimates for appropriation legislationnot the baselineare used when enforcing the caps.Therefore,the downward adjustments in CBOs baseline reflect the differences between the caps on base funding and the agencys estimates fo
271、r base funding provided by the continuing resolution in place on January 3,2024.For more on why CBOs cost estimate of that continuing resolution and funding in the agencys baseline differ,see Box 1-2.n.a.=not applicable.24THE BUDGET AND ECONOMIC OUTLOOK:2024 TO 2034 FEBRUARy 2024Box 1-2.Why CBOs Bas
272、eline Projections of Discretionary Funding for 2024Differ From Amounts in Its Cost Estimate for the Continuing ResolutionDiscretionary funding provided for 2024in the Congressional Budget Offices current baseline is$35billion less than the amount shown in CBOs cost estimate for the Further Continuin
273、g Appropriations and Other Extensions Act(Public Law118-22),referred to here as the continuing resolution.1 That difference occurs for several reasons(see the table).Major Reasons for the DifferenceThe largest driver of the difference between the amounts projected in the baseline and CBOs cost estim
274、ate for the continuing resolution arises from the estimated effects of the Fiscal Responsibility Act of 2023(P.L.118-5),which limits federal funding for discretionary programs over the current and next fiscal year.When the amounts provided by the continuing res-olution are annualizedthat is,calculat
275、ed as if the law was in effect through all of 2024funding provided for 2024exceeds those limits.As a result,CBO has adjusted the total amount of funding to reflect the expectation that the Administration would implement statutory mechanisms to enforce the caps.In total,those adjustments reduce discr
276、etionary funding shown in the baseline by$51billion in relation to the funding totals shown in the cost estimate for the continuing resolution.2 Another reason for the difference stems from changes in mandatory programs enacted in appropriation acts,which are known as CHIMPs.Following rules(known as
277、 scorekeeping guidelines)that govern how CBO produces its cost estimates,1.Congressional Budget Office,cost estimate for H.R.6363,the Further Continuing Appropriations and Other Extensions Act,2024(November13,2023),www.cbo.gov/publication/59755.2.For more information about how the caps may affect di
278、scretionary resources in 2024,see Congressional Budget Office,letter to the Honorable Jodey Arrington and the Honorable Brendan Boyle regarding implementing the statutory limits on discretionary funding for fiscal year 2024(January 4,2024),www.cbo.gov/publication/59861.Although the adjustments in CB
279、Os baseline affect only discretionary funding that is constrained by the caps(“base funding”in the table),statutory enforcement procedures eventually would affect most funding not constrained by the caps.The total effect of those procedures would still amount to approximately$51 billion.such changes
280、 made in appropriation acts are classified as reductions or increases in discretionary spending in cost estimates.When CBO produces its baseline estimates,though,those CHIMPs are reflected as reductions or increases in mandatory spending,following the scorekeeping guidelines that govern their classi
281、fication.3 On net,CHIMPs reduced CBOs estimate of discretionary funding in its cost estimate for the continuing resolution by$15billion.Shifting the effect of that reduction to CBOs projections of mandatory spending boosts net discretionary funding by the same amount.Other ReasonsTechnical and econo
282、mic updates to estimated components of discretionary funding also account for part of the difference.For example,some fees that agencies collect(for mortgage originations guaranteed by the Federal Housing Administration or aviation security fees collected by the Transportation Security Administratio
283、n,for instance)are estimated and are classified as offsets to discretionary budget authority.CBOs estimate for the continuing resolution used amounts projected in its May2023baseline,but updated estimates of that funding in CBOs most recent baseline result in larger estimates of fees.As a result,net
284、 discretionary budget authority in the baseline is$3billion smaller than the amount in CBOs estimate for the continuing resolution.In addition,current law requires CBO to exclude some discretionary funding from its cost estimates.Specifically,the 21st Century Cures Act(P.L.114-255)and division B of
285、the CARES Act(P.L.116-136,as amended)require that certain fund-ing provided to the National Institutes of Health and the Food and Drug Administration or derived from the Harbor Mainte-nance Trust Fund be excluded from CBOs cost estimates.That funding is reflected in CBOs baseline,however,accounting
286、for another$3billion of the overall difference.3.For more information about the guidelines,see Congressional Budget Office,CBO Explains Budgetary Scorekeeping Guidelines(January 2021),www.cbo.gov/publication/56507.Continued25CHAPTER1:THE BUDGET OUTLOOK THE BUDGET AND ECONOMIC OUTLOOK:2024 TO 2034Fin

288、ffset by the fees those agencies collect.(Those fees reduce total budget authority.)Because CBOs baseline does not reflect that assump-tion,its discretionary budget authority is$0.1billion larger than the amount in the cost estimate.Box 1-2.ContinuedWhy CBOs Baseline Projections of Discretionary Fun

292、irement or for disaster relief,certain program integrity activities,certain fire suppression operations,certain funding derived from the Harbor Maintenance Trust Fund,and certain programs designated in the 21st Century Cures Act.b.The FRA(Public Law 118-5)established limits on discretionary budget a
293、uthority.P.L.118-22,the continuing resolution in effect when CBO completed its analysis,provided funding at annualized levels in excess of the limits under section 102 of that law,which were in place at that time.CBOs baseline includes downward adjustments to funding to reflect the eventual effect o
294、f those limits.(See Box 1-1 on page 22 for more information.)c.When appropriation acts make changes to mandatory programs,those changes are recorded as discretionary costs or savings pursuant to Congressional scorekeeping guidelines.When those changes are reflected in CBOs baseline,they appear as ma
295、ndatory spending.d.Budget authority for some discretionary accounts is estimated.For example,the total amount of fees collected by the Transportation Security Administration(TSA)is not specified in appropriation acts because that amount is generally determined by the total number of air passengers.C
296、urrent law requires those collections to be credited against appropriations made to the TSA.e.Current law requires certain funding derived from the Harbor Maintenance Trust Fund or for certain programs designated in the 21st Century Cures Act be excluded from CBOs cost estimates.That spending is ult
297、imately reflected in the baseline.f.The budget committees directed CBO,in its cost estimate for H.R.6363,to assume that certain spending would be fully offset by collections not reflected in the baseline.26THE BUDGET AND ECONOMIC OUTLOOK:2024 TO 2034 FEBRUARy 2024cap is$41billion less than it was la
298、st year.14 Despite the drop in funding,nondefense discretionary outlays in 2024 are projected to total the same amount as was recorded in 2023$917billionprimarily because of spending from budget authority provided in previous years.Net Interest Outlays.In the budget,net outlays for interest consist
299、of the governments interest payments on federal debt,offset by interest income that the govern-ment receives.Net interest outlays are dominated by the interest paid to holders of the debt that the Treasury issues to the public.The Treasury also pays interest on debt issued to trust funds and other g
300、overnment accounts,but such payments are intragovernmental transactions that have no effect on the budget deficit.Net outlays for interest have risen by more than 35per-cent in each of the past two years and are projected to increase by 32percent this year.In CBOs projections,those outlays rise from
301、$659billion in 2023 to$870bil-lion in 2024,surpassing discretionary outlays for defense this year.Relative to the size of the economy,net outlays for interest rise from 2.4percent in 2023 to 3.1percent in 2024double the 1.5percent of GDP recorded for such outlays in 2021.The projected increase in 20
302、24occurs primarily because the average interest rate that the Treasury pays on its debt is higher this year and is expected to rise further as maturing securities are refinanced at rates that exceed those that prevailed when the securities were issued.15 For example,the interest rate on 10-year Trea
303、sury notes averaged 3.0percent in 2022 and 4.0percent in 2023;that rate averages 4.6percent in 2024in CBOs current economic forecast(see Chapter2).Debt held by the public(in nominal terms,rather than as a percentage of GDP)is on track to increase by 6percent from 2023 to 2024,which also boosts net i
304、nterest payments this year.Outlays From 2025 to 2034In CBOs baseline projections,federal outlays(adjusted to exclude the effects of timing shifts)rise from 14.Funding that is designated in keeping with the Deficit Control Act as an emergency requirement raises the caps by the amount of funding provi
305、ded.Section 103 of the FRA stipulated that discretionary emergency-designated funding provided by the Infrastructure Investment and Jobs Act,the Bipartisan Safer Communities Act,and section 443 of the Consolidated Appropriations Act,2023,does not count toward the caps.15.The average interest rate on
306、 debt reflects the interest rates on Treasury securities of different maturities,the maturity structure of securities issued,and the costs of inflation-linked payments made on some of those securities.$6.8trillion in 2025 to$10.0trillion in 2034,for an average annual increase of 4.5percent.16 Measur
307、ed in relation to the size of the economy,federal out-lays remain around 23percent of GDP for several years before gradually rising,reaching 24.1percent in 2034(see Figure 1-3).Mandatory Spending.In CBOs projections,nominal outlays for mandatory programs(net of offsetting receipts)rise at an average
308、 annual rate of 5percent over the 20252034period.In relation to GDP,those outlays increase from 13.9percent in 2025 to 15.1percent in 2034.At that point,they would be about 4percentage points higher than the average over the past 50years(see Figure 1-4).Two underlying trends,the aging of the populat
309、ion and growth in federal health care costs per beneficiary,put upward pressure on mandatory outlays.The aging of the population causes the number of benefi-ciaries of Social Security and Medicare to grow faster than the overall population,and federal costs per beneficiary for the major health care
310、programs continue to rise faster than GDP per person.(Spending for the major health care pro-grams consists of outlays for Medicare,Medicaid,and the Childrens Health Insurance Program,as well as premium tax credits for health insurance purchased through the marketplaces established under the Afforda
311、ble Care Act and related spending.The premium tax credits subsidize the purchase of health insurance.)As a result of those two trends,outlays for Social Security and Medicare increase in relation to GDP from 2025 to 2034.Beyond the 10-year period,the effects of those trends on federal spending persi
312、st,particularly for Medicare.16.CBOs projections follow provisions in section 257 of the Deficit Control Act,which requires CBO to project spending for certain programs,including Social Security and Medicare,under the assumption that they will be fully funded,and thus able to make all scheduled paym
313、ents,even if the trust funds associated with those programs do not have sufficient resources to make full payments.For example,CBO estimates that the Highway Trust Fund will be exhausted in 2028 and the Old-Age and Survivors Insurance Trust Fund will be exhausted in 2033.Nevertheless,CBOs baseline p
314、rojections reflect the assumption that funding will be adequate to make full payments as required by law.In addition,the Deficit Control Act requires CBO to project spending for certain mandatory programs beyond their scheduled expiration.Other rules that govern the construction of CBOs baseline pro

321、 projected to equal 3.1percent of GDP in 2025.Such spending includes outlays for income support pro-grams(such as unemployment compensation and SNAP),military and civilian retirement programs,most veterans benefits,and major agriculture programs.That spending also includes offsetting receipts(other
322、than those related to Medicare)collected by the federal government.In CBOs baseline projections,other mandatory spend-ing measured relative to GDP generally declines after 2025,falling to 2.5percent at the end of the projection period.(That spending,including substantial outlays in response to the p
323、andemic,peaked at 10.5percent of GDP in 2021.)The projected decline occurs in part because benefit amounts for many of those programs are adjusted for inflation each year,and in CBOs economic forecast,the growth of nominal GDP outpaces inflation.Growth in veterans benefits,which averages 6percent pe
324、r year(in nominal terms)after 2024,partially offsets the decline in other mandatory outlays.Figure 1-3.Total Federal Outlays and RevenuesPercentage of GDP Projected17.924.10102030401974198419942004201420242034RevenuesAverage revenues,1974 to 2023(17.3)Average outlays,1974 to 2023(21.0)OutlaysData so

328、rdance with section 257 of the Deficit Control Act,discretionary funding in future years is assumed to equal the amount provided so far for 2024including funding designated as an emer-gency requirementwith adjustments for inflation.18 When the projected amounts exceed the limits estab-lished by the
329、FRA,the total amount of budget author-ity in CBOs baseline is adjusted to comply with those limits.Those adjustments are incorporated in CBOs projections of discretionary funding in future years.Total discretionary budget authority projected for 2025amounts to$1.7trillion(see Table 1-6).Defense 18.T
330、he Deficit Control Act specifies which measures of inflation CBO should use to construct its projections:The employment cost index for wages and salaries of workers in private industry is used to adjust discretionary funding related to federal personnel,and the gross domestic product price index is
331、used to adjust other discretionary funding.For accounts with enacted advance appropriations,CBO projected future discretionary funding for those years for which funding has not been provided,starting with existing appropriations and adjusting those amounts for inflation.funding subject to the caps i
