Debt figures are often discussed without explaining their definition. Gross federal debt includes obligations between government accounts; debt held by the public is the metric that more directly describes borrowing from investors and other holders outside the federal government's own accounts.

The Congressional Budget Office's February 2026 outlook places federal debt held by the public at about 101% of gross domestic product in 2026 and projects further increases over the decade. It therefore supports our forecast that the ratio remains over 100% in fiscal 2027. We do not imply the country is unable to pay its bills or that an immediate financial crisis is certain.

Ratios can change through legislation, economic growth or interest rates, and the forecast is conditional on the CBO's baseline. The significance of persistent high debt is the limited room it may leave for future choices if borrowing costs rise or the economy weakens.
