Resilience of U.S. Markets Amid Iran Conflict

The U.S. financial markets have experienced volatility following the military conflict initiated by the United States and Israel against Iran on February 28, 2026. Despite this turbulence, investor returns have remained relatively strong. According to data from Morningstar, the average domestic stock mutual fund or exchange-traded fund recorded a modest decline of 1.2 percent in the first quarter of 2026. However, the overall performance over the past year has been positive, with the average domestic U.S. stock fund gaining 16.8 percent through March.

The conflict in Iran has led to fluctuations in oil prices and market sentiment. A fragile cease-fire, which began recently, contributed to a surge in the stock market, further stabilizing investor confidence. The S&P 500 index has nearly returned to its starting point for the calendar year, indicating a recovery trajectory despite the ongoing geopolitical tensions.

Historically, the U.S. stock market has demonstrated a capacity to rebound from various crises, including wars, pandemics, and economic downturns. This resilience is attributed to strong corporate earnings, which have continued to support investor returns even during challenging times. Analysts suggest that the current market conditions, while influenced by the conflict in Iran, reflect a broader trend of recovery and growth that has persisted since World War II.
