Futures Market & Commodities
On the oil market, prices moved narrowly over the holiday week, ending at USD 60.75/bbl, slightly below Monday’s USD 61.49/bbl. Geopolitical tensions offered brief support, but prices stayed capped by persistent oversupply concerns after Brent posted a 20% annual drop in 2025. With markets awaiting the next Opec+ meeting, trading remained muted and range‑bound.
European gas prices edged higher over the week, supported by colder weather forecasts and an unplanned Norwegian outage cutting flows by around 7 mcm/day until 1 January. After hitting a weekly low of EUR 27.27/MWh on Tuesday, prices rebounded toward the end of the week, closing at EUR 29.00/MWh on Friday. EU storage levels continued to decline to 62.2%, around 10 percentage points below last year.
European carbon prices stayed supported throughout the week, driven by the ongoing auction pause and a continued build‑up in speculative length, with investment funds extending their record‑high net long position to 117.6m allowances. The benchmark briefly hit EUR 88.88/t on Friday, the strongest level since August 2023, before settling at EUR 88.31/t.
Finally, power futures overall increased. Q2 26 closed rising 6.5% at EUR 41/MWh, while Q3 26 rose by 1.7% to EUR 67.6/MWh. Q4 26 rose by 1% to EUR 73/MWh. For annual contracts, Cal 27 rose by 1.2% to EUR 60.5/MWh, and Cal 28 decreased by 3.8% to EUR 52.6/MWh.
