Geopolitical Tensions Spike as Tehran Strike Triggers Safe-Haven Surge in Dollar and Bonds

A missile attack on a building in Tehran on March 1, 2026, intensified regional tensions, prompting an immediate market shift toward safe-haven assets. The U.S. dollar index (DXY) rose 1.8% to 106.75, its highest level since November 2024, as investors fled riskier currencies. Simultaneously, the yield on the 10-year U.S. Treasury note (US10Y) fell to 4.02%, its lowest since January, reflecting strong demand for government debt amid uncertainty. Crude oil prices surged on supply risk fears, with Brent crude (CL=F) climbing 8.3% to $98.60 per barrel, while WTI reached $94.20. The spike follows concerns over potential disruptions to energy flows from the Middle East, particularly through the Strait of Hormuz. Meanwhile, the CBOE Volatility Index (^VIX) jumped 22% to 27.4, signaling heightened market anxiety and a flight to perceived stability. The defense sector saw immediate reactions, with major contractors including Lockheed Martin (LMT) and Raytheon Technologies (RTX) posting 3.5% and 4.1% gains, respectively, as investors anticipated increased defense spending in response to regional escalation. In contrast, global equity indices fluctuated, with the S&P 500 down 0.6% and the MSCI World Index losing 0.9% during early trading as risk appetite waned. Market participants are now assessing the potential for broader regional spillover, particularly involving Iran’s allies and regional supply chains. The reaction underscores the market’s sensitivity to sudden geopolitical shocks, with dollar strength and bond demand serving as immediate buffers against volatility.
