DeficitsCBO projects a federal budget deficit of $3.3 trillion in 2020, more than triple the shortfall recorded in 2019. That increase is mostly the result of the economic disruption caused by the 2020 coronavirus pandemic and the enactment of legislation in response. At 16.0 percent of gross domestic product (GDP), the deficit in 2020 would be the largest since 1945.

The deficit in 2021 is projected to be 8.6 percent of GDP. Between 1946 and 2019, the deficit as a share of GDP has been larger than that only twice. In CBO’s projections, annual deficits relative to the size of the economy generally continue to decline through 2027 before increasing again in the last few years of the projection period, reaching 5.3 percent of GDP in 2030. They exceed their 50-year average of 3.0 percent in each year through 2030.

Debt. As a result of those deficits, federal debt held by the public is projected to rise sharply, to 98 percent of GDP in 2020, compared with 79 percent at the end of 2019 and 35 percent in 2007, before the start of the previous recession. It would exceed 100 percent in 2021 and increase to 107 percent in 2023, the highest in the nation’s history. The previous peak occurred in 1946 following the large deficits incurred during World War II. By 2030, debt would equal 109 percent of GDP.
