The United States remains the world's largest economy, but its own fiscal trajectory now poses the gravest threat to that standing, according to a Deutsche Bank Research Institute report. The report warns that mounting deficits and rising borrowing costs are gradually eroding a key structural advantage, and that this internal risk may outweigh external competition from China.
Fiscal Deterioration Threatens US Leadership
The report, published ahead of the 250th anniversary of the US Declaration of Independence, notes that the US has run federal deficits of around 5-6% of GDP since 2022, even though the economy has remained close to full employment. These are described as "the highest peacetime deficits in US history outside of a major recession." Consequently, debt held by the public is expected to exceed 100% of GDP this year. At the same time, the cost of servicing that debt has risen sharply, with interest payments now surpassing defense spending to become the fastest-growing component of the federal budget.
| Fiscal Metric | Current/Projected Level | Source |
|---|---|---|
| Federal deficit (% of GDP) | 5-6% since 2022 | Deutsche Bank Research Institute |
| Debt held by public (% of GDP) | >100% this year | Deutsche Bank Research Institute |
| Interest payments vs. defense spending | Interest now surpasses defense | Deutsche Bank Research Institute |
| Social Security trust fund exhaustion | Late 2032 | Deutsche Bank Research Institute |
| Medicare funding challenge | Shortly after Social Security | Deutsche Bank Research Institute |
Imminent Entitlement Program Pressures
Growing pressure from entitlement programs is a central concern. The report projects that the Social Security trust fund will be exhausted by late 2032, resulting in automatic benefit reductions unless lawmakers act. Medicare, it adds, is expected to encounter a similar funding challenge shortly afterward. "While the unsustainability of the US public debt trajectory has been in the headlines for many years, these events are now more imminent—ones that the next US administration that takes office after the 2028 election will have to face," the report states.
Dollar's Reserve Status Under Pressure
Sustained fiscal deterioration could slowly chip away at the US dollar's position as the world's dominant reserve currency, according to the report. It stresses that it does not foresee another currency replacing the dollar in the near future, but expects a "gradual erosion" rather than a sudden decline. The dollar's share of global foreign exchange reserves has dropped from roughly 72% to 58% over the past 20 years. During that period, central banks have increased their gold holdings, and a number of countries have begun exploring alternatives amid sanctions and evolving global trade patterns.
Structural Strengths Provide Cushion
Despite these risks, the report maintains that the US is well placed to preserve its economic leadership due to enduring structural strengths: deep capital markets, leadership in technology, abundant energy resources, and an advantage in artificial intelligence. "The challenges facing the US are real, but the weight of evidence still suggests it will remain the world's leading economy for the foreseeable future," the report concludes, adding that its "collective structural advantages remain difficult to replicate."
The report's central warning is clear: fiscal discipline will be essential to sustaining US economic dominance, and the window for corrective action is narrowing.
