WASHINGTON, OCTOBER 16 — The U.S. federal budget deficit for fiscal year 2026 is estimated to have reached $1.9 trillion, marking a 12% year-over-year increase. This significant expansion of the budget gap is primarily attributed to increased spending on healthcare, infrastructure, and defense, as well as lower tax revenues due to the economic impact of the COVID-19 pandemic. The growing budget deficit underscores the ongoing challenges in managing the nation’s finances, particularly in the face of mounting debt and the need for long-term fiscal sustainability.
The deficit-to-GDP ratio, a key measure of a country’s fiscal health, is projected to be around 8.6%, higher than the previous year’s 7.9%. This ratio reflects the federal government’s reliance on borrowing to fund its operations, which could have lasting implications for the economy.
The United States budget comprises the spending and revenues of the U.S. federal government. The budget is the financial representation of the priorities of the government, reflecting historical debates and competing economic philosophies. The government primarily spends on healthcare, retirement, and defense programs.
The budget typically contains more spending than revenue, the difference adding to the federal debt each year. CBO estimated in February 2024 that federal debt held by the public is projected to rise from 99 percent of GDP in 2024 to 116 percent in 2034 and would continue to grow if current laws generally remained unchanged.
Over that period, the growth of interest costs and mandatory spending outpaces the growth of revenues and the economy, driving up debt. The budget document often begins with the president’s proposal to Congress recommending funding levels for the next fiscal year, beginning October 1 and ending on September 30 of the year following. The fiscal year refers to the year in which it ends.
However, Congress is the body required by law to pass appropriations annually and to submit funding bills passed by both houses to the president for signature. Congressional decisions are governed by rules and legislation regarding the federal budget process. Budget committees set spending limits for the House and Senate committees and for Appropriations subcommittees, which then approve individual appropriations bills to allocate funding to various federal programs.
If Congress fails to pass an annual budget, then several appropriations bills must be passed as “stop gap” measures. After Congress approves an appropriations bill, it is then sent to the president, who may either sign it into law or veto it.
A vetoed bill is sent back to Congress, which can pass it into law with a two-thirds majority in each legislative chamber. Congress may also combine all or some appropriations bills into one omnibus reconciliation bill. In addition, the president may request and the Congress may pass supplemental appropriations bills or emergency supplemental appropriations bills.
Several government agencies provide budget data and analysis. These include the Government Accountability Office (GAO), the Congressional Budget Office (CBO), the Office of Management and Budget (OMB), and the Treasury Department.
These agencies have reported that the federal government is facing many important long-run financing challenges, primarily driven by an aging population, rising interest payments, and spending for healthcare programs like Medicare and Medicaid. During FY2022, the federal government spent $6.3 trillion. Spending as a percentage of GDP is 25.1%, almost 2 percentage points greater than the average over the past 50 years.
Major categories of FY 2022 spending included: Medicare and Medicaid ($1.339T or 5.4% of GDP), Social Security ($1.2T or 4.8% of GDP), non-defense discretionary spending used to run federal Departments and Agencies ($910B or 3.6% of GDP), Defense Department ($751B or 3.0% of GDP), and net interest ($475B or 1.9% of GDP). As the U.S. federal budget deficit continues to grow, experts warn of potential consequences for the economy.
