CBO’s current trajectory is roughly:
| Year | Debt held by public / GDP |
|---|---|
| 2026 | 101% |
| 2036 | 120% |
| 2056 | 175% |
That is a substantial deterioration from CBO’s 2025 long-term projection, which had debt reaching only 156% of GDP in 2055.
The change is particularly relevant to CRE work on Insoluble Insolvency. The 2026 CBO baseline now has the debt ratio increasing about 55 percentage points between 2036 and 2056, while net interest spending rises from 4.6% of GDP in 2036 to 6.9% in 2056. By 2056, CBO projects federal net interest spending will exceed spending on either Social Security or Medicare individually.
So the short answer is: around 2056—about 30 years from now—under CBO’s current-law assumptions–CRE estimates that the United States will be in a state of Insoluble Insolvency.
Importantly, 175% is not a ceiling. CBO explicitly says debt would be on track to continue increasing after 2056.
