European wholesale natural gas prices climbed sharply on Wednesday, with both key regional benchmarks rising over 3% amid growing concerns about winter fuel supplies. The benchmark front-month contract jumped 3.1% to 87.95 euros per megawatt-hour (MWh), while the British equivalent advanced 3.2% to 216.57 pence per therm. These gains pushed both contracts close to their highest levels since late 2022.
The rally came as fresh economic data revealed the heavy burden of high energy import costs on the British economy. The UK's annual consumer price inflation accelerated to 3.5% in September, up from 3.1% in August, surpassing market expectations. The UK's reliance on real-time imports of pipeline gas and LNG cargoes leaves it vulnerable to supply disruptions.
Persistent disruptions in the Persian Gulf have slashed Middle Eastern LNG deliveries to Europe by nearly 80% compared to last year. European utilities are now competing fiercely with Asian buyers for available Atlantic basin cargoes. Underground gas storage facilities in Europe are currently at 74.6% capacity, the lowest seasonal level since 2009, raising concerns about winter heating demand.
Year-to-date, the European benchmark has surged approximately 210%, while the British equivalent has gained roughly 196%. The combination of hotter-than-expected inflation data and ongoing energy supply disruptions has intensified market anxieties over fuel adequacy heading into winter.
