The U.S. stock market has thrived under Donald Trump’s leadership, with the Dow, S&P 500, and Nasdaq posting impressive gains of 57%, 70%, and 142% during his first term. Since Trump began his second term in January 2025, these indexes have continued to rally, up 13%, 20%, and 27%, respectively, as of late April 2026. However, this bullish trend faces a significant challenge due to geopolitical tensions, particularly following Trump’s military actions against Iran, which have led to a closure of the Strait of Hormuz and a sharp rise in energy prices.

The disruption in oil supply has already caused U.S. gas prices to surge, contributing to a notable increase in inflation, which is projected to rise further in the coming months. This inflationary pressure complicates the Federal Reserve’s monetary policy, especially as the market was previously banking on continued rate cuts to support high-growth sectors, particularly in technology and AI. The anticipated appointment of hawkish Fed Chair nominee Kevin Warsh may further limit the Fed’s ability to ease rates.

Market professionals should remain vigilant as the combination of rising inflation and potential interest rate hikes could challenge the sustainability of the current bull market. The impact of geopolitical events on inflation and monetary policy could reshape investment strategies in the near term.
