In Great Britain, the equivalent touched its highest level since late 2022, rising to 196 pence per therm and closing in on the psychologically critical 200p threshold.
Expanding Iran conflict threatens Strait of Hormuz LNG arteries
The primary driver behind the violent upside move in wholesale gas prices was a dramatic widening of kinetic military operations across the Middle East.
Trading desks scrambled to adjust risk models after Iranian-backed Houthis launched coordinated strikes against multiple Saudi Arabian cities on Tuesday, directly embroiling a key U.S. regional ally.
The escalation coincided with U.S. forces striking several Iranian oil tankers and Iranian forces launching a missile attack on a U.S. military base in Jordan.
The widening conflict directly imperils maritime navigation through the Strait of Hormuz, a critical transit choke point responsible for roughly 20% of global liquefied natural gas (LNG) traffic - chiefly originating from Qatar.
With flirting with the $100-a-barrel mark, the prospect of a prolonged blockade or transit restrictions in the Persian Gulf has forced European utilities into aggressive bidding wars against Asian buyers for Atlantic basin replacement cargoes.
Severe storage deficits compound winter supply vulnerabilities
The geopolitical shock comes at a precarious moment for European energy security, as the continent approaches the final weeks of the summer storage injection season with inventories significantly below historical norms.
Data from Gas Infrastructure Europe shows underground storage caverns filled to roughly 64% of capacity - lagging the five-year seasonal average.
A combination of intense summer heatwaves driving gas-fired power generation, ongoing offshore pipeline maintenance in Norway, and delayed Qatari LNG shipments has severely constrained storage replenishment throughout August and early September.
The steep surge in European wholesale natural gas - coupled with trading near $99.50 a barrel - is severely exacerbating cost-push inflation fears across European manufacturing and retail supply chains.
The persistent surge in energy input costs complicates the policy landscape for the European Central Bank (ECB) as its Governing Council prepares to announce its latest monetary policy decision on Thursday.
With headline Eurozone CPI accelerating on the back of rising energy components, money markets have fully priced in a 25-basis-point interest rate increase from ECB President Christine Lagarde and policymakers, keeping continental borrowing costs tightly anchored at multi-year highs.
