US energy stocks came under pressure on Monday after crude oil prices fell sharply following a breakthrough agreement between Washington and Tehran aimed at ending months of conflict and restoring stability to key global energy routes.
According to Reuters, the United States and Iran have agreed on terms to end hostilities, with both sides expected to sign a memorandum of understanding in Switzerland later this week. Pakistan played a key role in facilitating negotiations between the two countries.
The development eased concerns over potential disruptions in the Strait of Hormuz, one of the world's most critical oil transit corridors through which nearly 20% of global oil consumption passes. U.S. President Donald Trump announced that the waterway would remain open without restrictions and that the U.S. naval blockade of Iranian ports would be lifted.
The prospect of normalized oil flows triggered a sharp decline in crude prices.
Energy stocks, which had rallied strongly during the conflict amid fears of supply disruptions, reversed course as investors reassessed the risk premium embedded in oil prices. Despite Monday's decline, the S&P 500 Energy Index remains up more than 23% for the year.
Major oil producers led the losses. Exxon Mobil and Chevron dropped 6.2% and 4.6%, respectively. Other exploration and production companies, including Diamondback Energy, Devon Energy, ConocoPhillips and Occidental Petroleum, also recorded significant declines.
Refining companies were similarly affected. Shares of Valero Energy, Marathon Petroleum and Phillips 66 fell between 4.3% and 5.8%. Refiners had benefited during the conflict as supply concerns boosted fuel margins and increased demand for U.S. fuel exports.
The weakness extended beyond the United States. According to Reuters, European energy giants BP and Shell declined 4.5% and 5.2%, respectively, as falling crude prices weighed on the sector globally.
Analysts noted that while markets have welcomed signs of a diplomatic resolution, the recovery in oil production and exports across the Gulf region may take time. Damage caused during the conflict could delay a return to pre-war supply levels, making the pace of production recovery and shipping activity important factors for investors to monitor.
Some market observers also cautioned that oil prices may be reacting more to improving sentiment than to underlying supply-demand fundamentals. While optimism surrounding a potential end to the conflict has strengthened market confidence, concerns remain about tight global inventories and the possibility of supply constraints persisting through the summer months.
For now, however, investors appear focused on the prospect of reduced geopolitical risk, leading to a sharp unwinding of the gains that energy stocks had accumulated during the conflict.
