Reports emerged late this week that the United States and Israel are finalizing plans to strike Iranian energy infrastructure — including power plants and refineries — as soon as this weekend, a development that could reshape global energy markets just as summer demand peaks. Weekend Strikes on Iran Could Blow Up the Fragile Calm in Natural Gas — How Long Can U.S. Prices Stay Insulated?
Reports of an imminent U.S.-Israeli bombing campaign against Iranian power plants and refineries have injected fresh uncertainty into an energy market that was just beginning to price in détente. As recently as this week, improving prospects for a U.S.-Iran agreement and a potential reopening of the Strait of Hormuz had been pushing natural gas prices lower.
Henry Hub natural gas fell to $2.67/MMBtu on August 6, down 18% over the past month , reflecting ample domestic supply. A weekend strike would shatter that narrative overnight.
The Strait of Hormuz Is the Chokepoint That Matters Most
Roughly 27% of global maritime crude trade and 20% of the world's LNG pass through the Strait of Hormuz.
Iran declared the Strait "closed" back in March , and a new round of strikes risks hardening that blockade. The closure has already knocked out over 10 billion cubic feet per day of global LNG supply — about one-fifth of the total. Fresh hostilities would extinguish any hope of near-term reopening.
Iran's Retaliation Playbook Has Already Proven Devastating
After previous Israeli strikes, Iran hit Qatar's Ras Laffan LNG complex — knocking out 17% of its export capacity — with repairs estimated at three to five years.
It also struck a Saudi refinery and two Kuwaiti oil refineries. Iran has warned of "sweeping retaliation" if attacked again. For gas traders, that means the risk isn't just about Iran — it's about collateral damage to neighboring producers who supply Europe and Asia.
U.S. Domestic Prices Are Oddly Calm — For Now
Henry Hub prices have actually fallen 9% since the Strait closure because U.S. LNG export terminals are near capacity and domestic storage is healthy.
Inventories sat 6% above the five-year average at end of June and are forecast to reach 3,966 Bcf by October. But that insulation has limits. U.S. LNG terminals are already running at higher utilization to compensate for Hormuz disruptions representing over 10 Bcf/d, or 20% of global supply. Any surge in European or Asian spot demand could pull more molecules out of the domestic market.
The Timing Tells You Everything About the Fear
Planners want strikes concluded before Monday's market open — an implicit admission that the economic fallout could be severe. As Columbia University's Ira Joseph warned after prior escalation, the impact on European and Asian gas prices is "a very big deal" and "potentially quite recessionary." If strikes proceed and Iran retaliates against Gulf infrastructure again, the current $2.67 floor in U.S. natural gas could prove short-lived — and the global LNG crisis, far from winding down, would enter a dangerous new phase.
