Futures Market & Commodities
On the oil market, prices declined for a third consecutive week as oversupply concerns outweighed modest optimism around US–China trade discussions. Brent crude slipped to USD 64.70/bbl on Friday, down nearly 2% week-on-week, while WTI settled at USD 60.23/bbl. Early gains driven by hopes of tariff easing were reversed after the IEA reiterated expectations of a widening surplus, with global supply forecast to exceed demand by up to 4M bbl/day in 2026. Despite lingering geopolitical tensions, the well-supplied market and weak demand outlook continued to cap prices heading into November.
European gas prices traded slightly lower over the week, with the TTF front-month contract fluctuating between EUR 31.30 and EUR 31.80/MWh. Strong LNG inflows, mild weather, and improved Norwegian pipeline availability weighed on prices, despite brief support from unplanned outages at Troll midweek. EU storage sites remained around 83% full, nearly 12 percentage points below last year, but comfortable supply and above-average temperatures reduced heating demand.
European carbon prices remained steady within a narrow EUR 78–80/t band, with the Dec 25 EUA contract closing the week at EUR 78.87/t. Speculative support persisted, as investment funds maintained near-record net long positions around 94M tonnes. However, mild temperatures, strong wind output, and subdued industrial activity limited compliance demand. Analysts noted that market sentiment remained neutral, with low volatility and limited directional drivers ahead of upcoming EU climate policy discussions.
Finally, power futures remained relatively stable. Q1 26 closed decreasing 0.9% at EUR 64.1/MWh, while Q2 26 decreased by 2.2% to EUR 39.9/MWh. Q3 26 decreased by 0.3% to EUR 66.9/MWh. For annual contracts, Cal 26 decreased by 0.7% to EUR 61.1/MWh, and Cal 27 decreased by 0.3% to EUR 58.3/MWh.
