European Gas Prices Jump as Gulf Tensions Threaten LNG Flows

Key Moments

Market Reaction to Escalating Persian Gulf Conflict

European natural gas prices rallied sharply on Tuesday, reaching their highest levels since March, as intensifying military action in the Persian Gulf and a strong rebound in British contracts fueled concerns over a tight winter supply outlook.

The benchmark Dutch front-month contract advanced 1.3% to 71.30 euros per megawatt-hour (MWh). This move added to a nearly 5% rise in the previous session and kept prices well above the 70-euro mark.

In the United Kingdom, trading resumed after Monday’s public holiday with a forceful repricing. The NBP wholesale gas contract jumped 6.4% to 175.40 pence per therm, reflecting a catch-up move and mounting anxiety over regional supply security.

The ongoing rally has been underpinned by a growing geopolitical risk premium. Institutional energy desks have been moving quickly to lock in volumes as direct military engagements between U.S. and Iranian forces raised the prospect of sustained disruptions to critical shipping lanes.

Strait of Hormuz Risks Pressure LNG Supply

The main catalyst behind the upward shift in European gas curves has been the risk of prolonged transit interruptions through the Strait of Hormuz following direct military strikes in the area over the weekend.

U.S. forces carried out targeted air strikes on Iranian rocket launchers located on Larak Island. Those actions were followed by overnight Iranian missile attacks on two U.S. military air bases in Jordan. With U.S. President Donald Trump warning of further strikes against Iranian infrastructure, diplomatic efforts to secure commercial passage through the Strait have largely failed to gain traction.

The effective shutdown of this key waterway threatens around one-fifth of global liquefied natural gas (LNG) supply, much of which is shipped from Qatar, a major producer.

European utilities, already coping with reduced pipeline imports, are now confronting intense competition from Asian buyers for spot LNG cargoes. This scramble has pushed global seaborne freight rates and cargo premiums sharply higher.

Storage Shortfalls Deepen Winter Vulnerability

The geopolitical shock is coinciding with significant structural weaknesses in Europe’s gas storage system as the region prepares for the 2026/27 winter heating season.

Data from Gas Infrastructure Europe show that underground storage sites across the continent are currently at roughly 62% of total capacity, nearly 17 percentage points below the five-year seasonal norm. Elevated summer electricity consumption during heatwaves in Southern Europe, along with scheduled offshore pipeline maintenance in Norway, has sharply curtailed storage injections throughout August.

The latest surge in European wholesale natural gas prices, combined with Brent crude trading above $91 a barrel, has revived concerns about cost-push inflation in European financial markets.

ECB Policy Outlook as Energy Inflation Intensifies

Rising energy input costs are creating a significant complication for European Central Bank (ECB) policymakers ahead of their Sept. 10 monetary policy meeting.

Preliminary data for Eurozone August inflation released on Tuesday showed headline consumer price inflation accelerating to 3.3% year-on-year. The increase was driven primarily by higher energy prices.

The persistence of energy-related inflation pressures is reinforcing market expectations that the ECB will implement another 25-basis-point interest rate hike next week in an effort to prevent inflation expectations from becoming unanchored.
