NBP gas prices remain rangebound as storage levels remain on track to reach 90% by the end of October

17 September 2025

Gas Market

The NBP market remains rangebound with limited drivers influencing price direction. Curve contracts drifted sideways, recovering some premium after Monday’s losses. The front-month, October, rose by less than 1% to settle at 79.30p/th, while the front-winter contract, expiring in under two weeks, gained 0.67p settling at 85.99p/th. European storage levels stand at 80.83%, and at the current pace, inventories are projected to reach approximately 90% by end-October, offering the market reassurance ahead of winter. On the prompt, prices remain muted despite supply-side factors, including partial restrictions—escalating to a full shutdown on the 23rd September—at the Dragon LNG terminal, alongside ongoing North Sea maintenance.

Power Market

GB baseload contracts posted minor gains on Tuesday, largely supported by movements in the NBP gas market, though overall prices remain rangebound. Further out the curve, strength in the UKA carbon market continues to lend support, with both Dec-25 and Dec-26 contracts recording day-on- day gains. On the prompt, prices surged sharply, rising 250% from £28.90/MWh to £78.50/MWh, driven by forecasts of a fall in wind generation. Carbon prices extended gains, with the spot reaching €77.00/tonne and the Dec-25 contract closing at €77.49/tonne. These levels were last seen in February 2025, when gas prices traded around 85% higher, underlining the current disconnect between carbon and the broader energy complex.

Oil Market

Oil futures extended gains on Tuesday, lifted by escalating risks to Russian supply following fresh Ukrainian drone strikes on export terminals and refineries. The front-month Brent contract settled at $68.47/bbl, up $1.03 or 1.2%, while WTI rose $1.22 to $64.52/bbl. Prices briefly rose higher in early trading after the Russian oil pipeline operator, Transneft, cautioned producers that output cuts may be necessary, but gains moderated as traders weighed the Federal Reserve’s pending policy decision amid expected interest rate cuts. The attacks by Ukraine have removed some 300,000 bpd of refining capacity offline this month, according to Goldman Sachs. Despite this sentiment was tempered by broader macro concerns, as investors awaited signals from the Fed on interest rates and their implications for fuel demand.

Markets this morning

NBP gas is trading higher this morning, though prices remain within 4–5% of recent 18-month lows. Norwegian North Sea maintenance continues, with capacity on the Langeled pipeline reduced by 21 mcm/day, though this work is expected to conclude tomorrow. Following yesterday’s gains, EUA prices are holding broadly flat in early trading. In oil, prices have eased from last night’s close as the market awaits an expected U.S. Federal Reserve interest rate cut later today, although downside remains capped by ongoing geopolitical tensions.
