US debt to GDP ratio

The clearest illustration is the peak. The ratio hit 132.7% in Q2 2020 not only because the government borrowed heavily but because output fell at the same time, so the numerator rose while the denominator shrank. Over the two years that followed the ratio came down without any policy directed at it, as GDP recovered and inflation raised the nominal denominator. Nothing was repaid.

That is the mechanism behind the most common way out of a high ratio historically, which is not repayment but nominal growth. It also means a falling ratio is not automatically good news and a rising one is not automatically borrowing. Anyone using this series as a fiscal scorecard should look at the two inputs separately, which is why both are published in the CSV and in the card at the top of this page.

What is the US debt to GDP ratio right now?

About 123.3%, pairing Treasury's debt figure from 14 September 2026 with the last published GDP for Q2 2026. The last quarter where both inputs are measured is Q2 2026 at 121.5%. The live number runs slightly high because GDP is held at last quarter's level while the debt keeps moving.

Does growth really collapse above 90% debt to GDP?

Not in the US record, and the study that claim comes from was corrected. Reinhart and Rogoff's 2010 paper reported a sharp drop above 90%. In 2013 Herndon, Ash and Pollin found a spreadsheet row-selection error excluding five countries, along with selective data exclusions and an unusual weighting scheme, and the corrected average growth above 90% came out around 2.2% rather than negative. On US data alone, real GDP grew 2.95% annualised in quarters that began below 90% and 2.52% in quarters that began above it, a gap of 0.43 percentage points rather than a cliff.

When did the US cross 100%?

In Q4 2015, and it has not been below it since. The ratio crossed 90% in Q4 2010 and has now spent 63 consecutive quarters above that line.

Has it ever been higher?

Yes. The record high on this series is 132.7% in Q2 2020, when GDP collapsed and emergency borrowing arrived in the same quarter, so both halves of the ratio moved the wrong way at once. It fell back over the following two years without any policy aimed at it, which is a useful reminder that the denominator moves too.

Why does this page compute the ratio instead of using FRED's?

FRED publishes the ratio ready-made and we commit it as the check rather than the source. Across 239 comparable quarters our figure and theirs agree to a median of 0.000%. Two quarters are set aside because FRED's underlying debt series carries the wrong month there, which is documented on the national debt page. Computing it also lets the series run a quarter further forward than the published one, which lags.

Is a high ratio the reason to buy gold?

The record does not support that link directly. The ratio rose through the whole of the 1980s and 1990s while gold fell for two decades. What a high ratio does support is a narrower claim about fiscal room and the interest bill, which is a separate page and a separate argument.
