European Gas Prices Climb for Fourth Straight Week Amid Hormuz Tensions

European natural gas prices edged higher on Friday, setting benchmark contracts on course for a fourth consecutive weekly gain as escalating geopolitical tensions in the Middle East roil global energy markets. The surge has pushed prices to their highest levels since 2023, reflecting deep-seated concerns over winter supply security.

The front-month Dutch TTF contract, the continental benchmark, was trading near €72.50 per megawatt-hour (MWh), locking in a weekly gain of over 8%. In the UK, the equivalent NBP wholesale contract held firm near 179 pence per therm, capping a weekly advance of more than 9%.

Geopolitical Tensions Disrupt Key LNG Route

The rally is primarily fueled by a significant geopolitical risk premium embedded in forward prices. Traders are reassessing winter supply after direct military strikes between U.S. and Iranian forces effectively crippled commercial tanker transit through the Strait of Hormuz, a critical chokepoint for global energy flows.

This maritime blockade directly threatens approximately 20% of the world's liquefied natural gas (LNG) supplies, which largely originate from Qatar. The disruption has forced European utilities into intense bidding wars with Asian buyers to secure alternative seaborne cargoes, establishing an elevated floor under global LNG spot prices.

Low Storage Levels Amplify Supply Concerns

The geopolitical shock comes at a critical time for Europe, which is in the final stages of replenishing its gas inventories ahead of the winter heating season. The continent's supply buffer is already under strain.

Data from Gas Infrastructure Europe shows that underground storage caverns are currently filled to just 62% of capacity, lagging the five-year seasonal average. August storage injections were constrained by several factors:

• Intense summer heatwaves driving up gas-fired power generation.
• Routine offshore pipeline maintenance in Norway.
• Earlier delays in Qatari LNG shipments.

Inflationary Pressure Mounts for ECB

The sustained energy price surge is compounding inflationary pressures across the Eurozone, creating a policy challenge for the European Central Bank (ECB). Preliminary data for August showed headline inflation accelerating to 3.3% year-on-year, driven by a 14.3% jump in the energy component.

This persistence of energy-driven inflation increases pressure on the ECB to maintain a hawkish monetary policy stance at its upcoming meeting on Sept. 10. Policymakers must now weigh the risk of rising price expectations against emerging signs of slowing regional economic growth.
