UK Energy Market Report – 17 June 2026

Wholesale gas and power slide as the Middle East risk premium drains out of the curve.

UK energy markets extended a sharp sell-off into Tuesday as the risk premium built up through this spring’s Middle East conflict drained out of the curve.

News of a US-Iran framework deal, paired with milder UK temperatures, dragged near-term gas and power to their lowest levels in months. The front of the curve led the move, while winter and longer-dated contracts held firmer, a sign the market still wants cover for the cold season.

Gas Market

NBP spot settled at 102.30 p/therm. The July-26 contract fell to 99.40 p/therm, down 1.6% on the day and a hefty 15.2% over the week, dipping back below the 100 mark.

The driver is geopolitics. A US-Iran framework deal, with a 60-day ceasefire and the reopening of the Strait of Hormuz, is due to be signed on 19 June in Geneva. If it holds, Persian Gulf LNG cargoes start flowing again and a chunk of the supply fear that built up since March comes out of the price.

Closer to home, warmer weather has cut heating demand, and a heavy run of US LNG arrivals into north-west Europe has kept the system well supplied.

The winter is where the market is more cautious. Winter-26 held at 105.13 p/therm, actually up 0.4% on the day even as the week showed a 13.1% fall. Cal-27 sits down at 86.60 p/therm, off 7.7% on the week, leaving the curve in steep backwardation.

Electricity Market

Day-ahead baseload power printed at £105.12/MWh, sitting above the forward contracts as below-average wind kept near-term spot tight.

The forwards told the softer story. July-26 power fell to £92.62/MWh, down 9.2% on the week, with Winter-26 at £96.33/MWh, off 7.3%, and Cal-27 down to £81.08/MWh.

Gas is still the marginal price-setter on the UK grid, so power has tracked the gas curve lower. French nuclear constraints and a tighter near-term supply picture are stopping the spot price from falling as fast as the forwards.

Improving wind and solar forecasts into late June should ease day-ahead pressure if they hold.

Oil, Carbon and Global Commodities

Brent crude has been the clearest signal of the de-escalation. It fell toward $80 a barrel, a fourth straight session of losses and the lowest since early March, as the prospect of Hormuz reopening removed a large slug of geopolitical premium.

European carbon softened in sympathy, with EUA December contracts easing in a well-supplied market. TTF gas in mainland Europe dropped to its lowest since April, reinforcing the move in UK NBP.

Storage and Supply Outlook

The supply backdrop is comfortable. European storage continues to refill through the injection season, helped by strong LNG send-out and steady Norwegian pipeline flows running near 290 mcm/day after Aasta Hansteen returned from maintenance.

For now there is no fresh Ofgem intervention in the frame, and the market’s attention is fixed on whether the 19 June signing actually lands. A confirmed deal points to more downside; any slippage risks a quick reversal of this week’s falls.

What This Means for Your Business

This is a genuine reset lower in near-term prices, and short-dated buyers have a window they did not have a week ago.

The catch is the shape of the curve. With winter holding firm and Cal-27 already well below the front, locking everything at spot leaves you exposed if the geopolitical calm does not last. A staged approach, taking advantage of the front-month weakness while keeping some winter cover, fits the current backwardation.

The 19 June signing is the event to watch. If you have renewals or budget decisions landing this quarter, it is worth being ready to move quickly in either direction.
