Strait of Hormuz Closure Triggers Global LNG Supply Shock, Boosting U.S. Exporters

Global liquefied natural gas (LNG) markets are facing severe volatility following the closure of the Strait of Hormuz, a critical maritime artery that previously handled 20% of the world's LNG shipments. The disruption, stemming from the ongoing conflict with Iran, has pushed LNG prices up by approximately 33%. Qatar, which holds roughly 10% of global gas reserves and provides 20% of global supply, has ceased exports due to the blockade. Further compounding the crisis, two LNG trains—in which ExxonMobil holds an interest—were damaged in Iranian attacks and are expected to require three to five years for repair. U.S. exporters have stepped in to mitigate the shortfall. In the first four months of the year, U.S. LNG loads reached a record 32.2 million metric tons, a 28% year-over-year increase. This month alone, U.S. shipments of 7 million metric tons have nearly entirely offset the 6.9 million tons displaced from Qatar. Industry leaders are seeing immediate gains. Venture Global's Plaquemines terminal saw a 240% surge in first-quarter loads to 6.5 million tons, while Cheniere Energy's Sabine Pass terminal handled 7.9 million tons, representing 25% of all U.S. exports. Midstream players like Kinder Morgan are also benefiting from increased pipeline volumes. However, the supply crunch is creating headwinds for LNG-dependent economies in Europe, China, India, and Japan. Europe, which receives 72% of U.S. LNG exports, is particularly vulnerable as it continues to pivot away from Russian gas. Higher energy costs are expected to erode profit margins for utilities and manufacturers across these regions.
