UBS Warns Iran Conflict Strains US Debt

UBS is warning that the Trump administration's military action against Iran, combined with high defense spending and subsidies, could destabilize U.S. government debt markets. The bank highlights rising concern among global investors about the sustainability of U.S. borrowing amid growing geopolitical risk.

The U.S. national debt currently stands at approximately $38.8 trillion. This figure precedes the full budgetary impact of "Operation Epic Fury," a joint U.S.-Israeli military campaign initiated against Iran on February 28, 2026. The stated goals of the operation include the destruction of Iran's missile inventory and naval forces to prevent the nation from developing nuclear weapons. The conflict adds to a period of already elevated military spending. In the two years since October 2023, the U.S. has spent over $30 billion on military aid to Israel and its own operations in the Middle East. These figures include costs associated with Red Sea carrier strike groups and missile defense. President Trump has indicated the current operation in Iran could last for about a month. Historically, heightened geopolitical risk in the Middle East often triggers a "flight to safety," where investors purchase U.S. Treasury bonds, seen as a secure asset. This increased demand can temporarily lower borrowing costs for the U.S. government. Initial market reactions to Operation Epic Fury have included a surge in the price of gold, another traditional safe-haven asset. However, the long-term fiscal outlook presents a different picture. The Congressional Budget Office (CBO) projected the U.S. budget deficit for fiscal year 2026 to be $1.9 trillion, with debt held by the public reaching 120% of GDP by 2036. These projections do not account for the costs of the new conflict. Concerns are growing that mandatory spending on programs like Social Security and Medicare, combined with rising interest payments, will consume all federal revenues within a decade. The added expenditure of a sustained military campaign layers on top of a fiscal situation some analysts already deemed unsustainable. With $9.97 trillion in Treasury securities set to mature in 2026, the government's borrowing needs are substantial. Some economists warn that as the U.S. fiscal position erodes, financial markets could become less willing to absorb the rising debt, leading to disruptions.
