Oil prices rise, stock futures advance as U.S.-Iran airstrikes continue in Gulf

Key Facts

1Oil prices rose and U.S. stock-index futures advanced after the U.S. and Iran continued airstrikes in the Persian Gulf, renewing fears of a Strait of Hormuz closure.

In a new escalation threatening global energy security, the United States and Iran continued trading airstrikes in the Persian Gulf, pushing oil prices higher and lifting U.S. stock-index futures amid renewed fears of a Strait of Hormuz closure, according to news reports. MarketWatch reported that the continued skirmishes are stoking investor concerns about global crude supplies through one of the world's most critical maritime chokepoints.

These developments follow weeks of rising tensions in the region, with the Strait of Hormuz handling roughly one-fifth of the world's oil supply, making any threat to its passage a direct driver of the geopolitical risk premium in crude prices. In initial reactions, West Texas Intermediate crude futures posted notable gains, while S&P 500 futures edged higher, though broader risk-off sentiment could weigh on equities in the days ahead.

Investors are monitoring any fresh diplomatic or military signals that could determine the trajectory of the escalation, as well as weekly U.S. crude inventory data from the American Petroleum Institute and the Energy Information Administration, which may reflect supply disruptions. Markets are also awaiting comments from major central bankers, including the Federal Reserve and the European Central Bank, to gauge the impact of the geopolitical shock on inflation and growth.
