Oil Rises, Stock Futures Gain Amid U.S.-Iran Airstrike Exchange

Oil prices climbed and stock futures edged up Sunday as U.S.-Iran tensions in the Persian Gulf raised fears over Strait of Hormuz disruptions.

If you woke up Sunday and checked your portfolio app, here's the headline you needed: oil prices were climbing and U.S. stock-index futures were nudging higher — but not exactly for cheerful reasons.

If you're not familiar, think of it as the world's most important oil pipeline, except it's actually a narrow waterway between Iran and Oman.

For everyday investors, moments like these are a good reminder that global events you might not track closely — airstrikes in a region thousands of miles away — can absolutely move your 401(k) on a Monday morning. Keeping a cool head and avoiding knee-jerk reactions is usually the smarter play when geopolitical headlines drive short-term volatility.
