- Crude oil futures (CL=F) rose 2.1% to $89.40 per barrel amid regional tensions
- Defense stocks: Raytheon (RTX) +4.2%, Lockheed Martin (LMT) +3.6%

Amid a sharp escalation in geopolitical tensions between Iran and the United States, global financial markets experienced widespread volatility on March 1, 2026. The MSCI World Index dropped 3.8%, while European and Asian bourses fell between 2.5% and 4.1%. In contrast, the S&P 500 rose 0.7%, and the Nasdaq Composite gained 0.4%, defying expectations of broad-based sell-offs. The resilience was underpinned by strong domestic fundamentals and a flight to quality within U.S. equities. Defensive sectors, particularly defense and energy, saw notable inflows. Raytheon Technologies (RTX) rose 4.2%, while Lockheed Martin (LMT) climbed 3.6% as investors priced in potential defense spending increases. Energy stocks were also supported; crude oil futures (CL=F) rose 2.1% to $89.40 per barrel, reflecting supply concerns amid the regional standoff. Volatility measures tell a deeper story: the CBOE Volatility Index (^VIX) dipped 1.9% to close at 15.3, signaling reduced fear in U.S. markets compared to global peers. This suggests that institutional investors viewed U.S. assets as relatively insulated from geopolitical shocks, despite escalating risks. The divergence underscores a shift in investor behavior—favoring U.S.-based large-cap companies with stable cash flows and minimal international exposure. Tech giants like Apple (AAPL) rose 1.1%, driven by strong earnings momentum and a resilient iPhone demand, even as supply chain concerns simmered. Market participants now assess the U.S. equity market not just as a growth engine, but as a sanctuary during international crises, a dynamic that may influence portfolio allocations for years to come.
