What drove federal debt from 32% to 98% of GDP?
Core argument: Federal debt held by the public rose from 32% of GDP at the end of FY 2001 to 98% at the end of FY 2023, after CBO projected in 2001 that the debt would be effectively paid off by the end of FY 2009.
In 2001, the Congressional Budget Office (CBO) projected that the national debt would effectively be paid off in full by the end of Fiscal Year (FY) 2009. Instead, federal debt held by the public grew from 32% of Gross Domestic Product (GDP) at the end of FY 2001 to 98% of GDP at the end of FY 2023. Reviewing major deficit-increasing legislation and executive actions over the past 22 years, we find that major tax cuts are responsible for 37 percentage points of debt-to-GDP, net discretionary spending increases and major Medicare expansions are responsible for 33 percentage points, and response measures to the Great Recession and the COVID-19 pandemic and recession – before accounting for economic feedback – explain 28 percentage points. Absent any two of these sets of policies, the debt-to-GDP ratio would be near the FY 2001 level. Debt would be fully paid off without tax cuts, spending increases, and recession responses.
