European and British wholesale natural gas contracts surged on Wednesday to levels not seen since 2023, driven by renewed military blows in the Persian Gulf and an emerging supply shortfall that eclipsed price peaks recorded earlier in the Middle East conflict.
In continental Europe, the Dutch front-month benchmark climbed to 74.32 euros per megawatt-hour (MWh), reaching its strongest level in nearly three years. In Great Britain, the National Balancing Point (NBP) front-month contract rallied to 183.95 pence per therm, also marking a 2023-era high.
Market participants said the latest price moves represent a shift into a higher-risk pricing regime for wholesale gas - one in which traders and energy desks are factoring in prolonged operational disruptions along global liquefied natural gas (LNG) supply chains ahead of the northern hemisphere heating season.
Direct strikes against Islamic Revolutionary Guard Corps (IRGC) positions and retaliatory missile attacks on U.S. air bases in Jordan have had an immediate effect on commercial shipping patterns through the Strait of Hormuz. While U.S. officials continue to state the waterway remains open to navigation, maritime tracking data shows that commercial passage is running at only a fraction of pre-conflict volumes.
Traders cited additional escalation risk after U.S. President Donald Trump signaled the possibility of "harder" military measures, including options that could target Iran’s Kharg Island export facility. Against that backdrop, market players saw little chance of a rapid diplomatic resolution and flagged the effective choke on the Strait as a threat to roughly 20% of global seaborne LNG transit - the majority of which originates from Qatar. That bottleneck is forcing European buyers to compete more aggressively with Asian utilities for uncommitted Atlantic basin cargoes.
The supply shock arrives at a precarious moment for Europe's gas system. Data from Gas Infrastructure Europe indicates regional storage is sitting at about 62% of capacity, below the five-year seasonal average. The shortfall in injections stems from several factors this summer: severe heatwaves across Southern Europe raised gas-fired power generation, routine offshore pipeline maintenance in Norway constrained flows, and delayed shipments of Qatari LNG further restricted the rate at which underground facilities could be replenished throughout August.
Trading desks warned that the combined effect of slower storage refill and potential continued interruptions to seaborne LNG deliveries through autumn could leave Europe vulnerable to sharp price spikes and, in extreme scenarios, supply rationing if a prolonged cold snap hits during winter.
The surge in energy costs is already complicating the policy backdrop for the European Central Bank (ECB). The ECB's Governing Council is scheduled to meet on Sept. 10, and preliminary August data for the Eurozone showed divergent inflation signals: core inflation eased slightly to 2.4%, while the headline rate accelerated to 3.3%, with energy components up 14.3% and accounting for much of that uptick.
Clear summary
Renewed military action in the Persian Gulf and restricted commercial transit through the Strait of Hormuz have pushed European and U.K. front-month gas benchmarks to their highest readings since 2023. Around 20% of global seaborne LNG transit is at risk, regional storage refill rates trail seasonal norms at roughly 62% of capacity, and energy-driven inflationary pressure is rising ahead of a key ECB policy meeting.
Key points
- Dutch front-month gas hit 74.32 euros/MWh; U.K. NBP front-month reached 183.95 pence/therm.
- Commercial shipping levels through the Strait of Hormuz are operating at a fraction of pre-war volumes amid direct strikes and missile exchanges.
- European storage is about 62% full, trailing the five-year seasonal average; reduced injection rates have been driven by higher gas-fired power demand, Norway pipeline maintenance, and delayed Qatari LNG shipments.
Risks and uncertainties
- Sustained disruption of seaborne LNG flows - impacting roughly 20% of global seaborne LNG transit - could force competition between European and Asian buyers for Atlantic cargoes, increasing spot-price volatility (affecting energy and utilities sectors).
- Below-average storage replenishment ahead of winter raises the chance of sharp price spikes and potential supply rationing during extended cold periods (affecting household heating, power generation, and industrial activity).
- Rising energy costs are contributing to headline inflation pressures in the Eurozone - complicating monetary policy considerations for the ECB ahead of its Sept. 10 meeting (impacting financial markets and macroeconomic policy decisions).
Energy traders and supply chain analysts will be watching maritime traffic patterns, storage injection rates, and rerouting of LNG cargoes closely in the weeks ahead as markets balance immediate geopolitical risk against the operational realities of loading, transit and onshore storage constraints.
