Summary: European wholesale natural gas benchmarks rose sharply on Monday, marking their strongest levels in more than a month after Iran declared the strategic Strait of Hormuz closed 'until further notice' following renewed military strikes between U.S. forces and Tehran. The announcement and the resulting anxiety over potential disruptions to global liquefied natural gas (LNG) flows prompted notable gains in both continental and U.K. contracts, even as U.S. Central Command said commercial transit remained possible.
The Dutch front-month contract, the regional benchmark, climbed 3.5% to trade at 50.37 per megawatt-hour in early sessions. The British front-month contract tracked the continent higher, jumping about 4% as energy markets moved defensively in response to the abrupt deterioration of regional stability.
The immediate trigger for the price spike was Iran's statement that it had closed the Strait of Hormuz 'until further notice' after fresh exchanges of military strikes between U.S. forces and Tehran. Despite the U.S. Central Command maintaining that the shipping lane remains open to commercial transit, the mere prospect of a protracted shutdown reverberated through trading desks because of the waterway's outsized role in LNG logistics.
Market participants and analysts highlighted the strategic importance of the passage, noting it handles roughly one-fifth of the world’s total LNG trade and carries the bulk of Qatar’s exports. That concentration of flows through a single maritime corridor means any sustained curtailment of Gulf LNG shipments would quickly intensify competition among buyers, including those in Asia, and could push European prices higher.
Compounding the supply concern are Europe’s current storage levels. Facilities are being refilled ahead of the 2026/2027 winter heating season but stand at roughly 47% capacity, below the roughly 56% recorded at this same point last year. Analysts warned that with lower relative stocks and the risk of export disruptions, market volatility is likely to remain intense going forward.
In short, the combination of heightened geopolitical risk around the Strait of Hormuz, significant reliance on Gulf LNG volumes, and below-average storage positions has driven a defensive market reaction and renewed upward pressure on European wholesale gas prices.
