Global Oil Prices Surpass $100 Amid Red Sea Attacks and Escalating U.S.-Iran Conflict

On July 23, 2026, Brent crude oil prices surged past $100 per barrel for the first time since May, driven by Houthi rebel attacks on two Saudi Arabian tankers in the Red Sea and intensified military exchanges between the United States and Iran. The price spike triggered a significant sell-off on Wall Street, with the S&P 500 and Nasdaq suffering sharp losses as investors weighed the risks of renewed inflation and potential Federal Reserve interest rate hikes. The geopolitical instability follows the collapse of a peace agreement and 12 consecutive days of U.S. retaliatory strikes against Iranian targets following the deaths of two U.S. troops in Jordan.

// Background

Oil prices previously hit $100 in March 2026 following the outbreak of war involving Iran but receded in late May during brief peace negotiations. The current escalation follows the killing of two U.S. soldiers in Jordan and the subsequent collapse of the peace deal, leading to a 12-day U.S. bombing campaign against Iranian targets.
