UBS Warns on US Debt Over Iran War
UBS is warning that the U.S. military's escalating action against Iran poses a new risk for government debt markets. The bank cautioned that surging defense spending could further strain American fiscal stability and negatively impact the U.S. dollar.
The current conflict escalated on February 28, 2026, when the U.S. and Israel conducted joint military strikes against Iran. These attacks targeted Iranian leadership, military infrastructure, and nuclear facilities, resulting in the death of Iran's Supreme Leader, Ali Khamenei. In response, Iran launched missile and drone attacks on Israel and U.S. military bases in several Gulf countries, including Qatar, Kuwait, and Saudi Arabia. This military action comes at a time when U.S. government debt has reached over $38.8 trillion. The national debt is currently growing by approximately $4.5 billion per day, and the country's debt-to-GDP ratio stands at 136%. U.S. defense spending for fiscal year 2026 is projected to surpass $1 trillion, representing about 3.3% of GDP. This figure is higher in inflation-adjusted terms than at any point during the Cold War, though it remains a smaller percentage of the national economy than during the Vietnam era, when it reached 8-10% of GDP. The United States' military expenditures account for nearly 40% of the global total. The conflict has already impacted global markets, with oil and gold prices surging. A key chokepoint for global energy trade, the Strait of Hormuz, is now in an active warzone, causing shipping insurance premiums to spike and some vessels to reroute. Analysts are concerned that a sustained disruption could fuel a cost-of-living crisis and complicate the Federal Reserve's monetary policy. President Donald Trump has stated the military operation could take "four weeks or less," while his administration's stated goal has shifted beyond nuclear containment to regime change in Iran. As of March 2nd, the Pentagon has confirmed the deaths of four U.S. service members in the conflict. Iran has retaliated by targeting key energy infrastructure, including a Saudi Aramco oil refinery in Ras Tanura. The U.S. and several Gulf allies, including Saudi Arabia and the UAE, have issued joint statements condemning Iran's retaliatory strikes and are weighing a potential collective response.
