Federal Debt to GDP
Federal debt held by the public — Treasury securities owned by investors outside the US government (households, funds, foreign central banks, the Fed) — expressed as a percentage of GDP. It is the debt measure economists watch, because it captures the government's borrowing from real lenders rather than the intragovernmental IOUs (Social Security, etc.) that inflate the gross total. The secondary line shows that gross total for context.
Latest reading
As of January 2026, Debt / GDP (Held by the public (% of GDP)) stands at 98.7% — up from 98.2% the prior reading. The ratio peaked near 106% of GDP funding World War II, fell to ~23% by the mid-1970s as the postwar economy grew faster than the debt, then climbed steadily — through the 1980s deficits, the 2008 crisis, and the 2020 pandemic — back toward 100%. Held-by-public debt is the ~99% figure; the gross total (including intragovernmental holdings) sits above 120%, which is the number behind most "debt exceeds GDP" headlines. Direction and the growth-vs-rate gap matter more than any single level. Series history runs from 1939 to present.
