Middle East tensions push gas to 120p/therm as European storage injection pace hits five-year low

Geopolitical risk dominated UK energy markets during the week of 2-6 June, as renewed Middle East tensions sent NBP gas surging to a weekly high of 120.86p/therm on Monday before a partial recovery in Norwegian supply and intermittent bouts of strong wind generation kept prices from extending their gains.Day-ahead gas closed the week near 119p/therm, a rise of approximately 3.5% on the prior Friday, with the forward curve also firmer across winter contracts.Winter 2026 broke above 122p/therm amid growing market concern about the pace of European storage injections, which by early June was running at the slowest rate for this time of year in five years.

Gas Market Review

UK gas markets opened Monday 2 June with their sharpest single-session rally in several weeks, the NBP day-ahead contract settling at 120.86p/therm, a gain of 10.36p on the day.The move was driven by stalled US-Iran nuclear talks and continued Israeli military operations in Lebanon, which raised fears over regional energy infrastructure disruption.Tighter near-term fundamentals amplified the rally: Norwegian pipeline nominations fell to 281 mcm/day following unplanned outages at Aasta Hansteen and Oseberg, UK LNG terminal send-out held near 9 mcm/day with flexible cargoes being diverted to Asia where the JKM premium remained commercially compelling, and reduced wind generation increased gas-for-power demand across the UK grid.The rally partially unwound through Tuesday and Wednesday as markets recognised no direct supply disruption had materialised. Day-ahead fell back below 117p/therm at its mid-week low before stabilising near 118.50p/therm on Wednesday. Norwegian nominations recovered to around 305 mcm/day by Thursday, leaving the British gas system approximately 13 mcm/day long and reducing near-term upside pressure.The forward curve proved more resilient than spot. Winter 2026 gas closed the week above 122p/therm, reflecting persistent concern about European storage injection pace and the ongoing geopolitical risk premium. Summer 2027 held near 85p/therm, suggesting the market expects some price normalisation once storage refill concerns ease and seasonal demand softens.

Electricity Market Review

UK power markets reflected gas market volatility but with a wider intraday price range driven by sharply fluctuating renewable output.Monday’s day-ahead baseload contract settled at 111.00 £/MWh, reflecting both geopolitically elevated gas costs and low wind generation across Great Britain.By Wednesday, wind output had surged by around 153% day-on-day, cutting combined cycle gas turbine output by approximately 67% and pulling day-ahead power down to 67.79 £/MWh, a near-£45/MWh swing in two sessions that underlined the market’s sensitivity to short-notice renewable variability.The availability of the UK’s nuclear fleet added to the volatility risk through the week, with five of the nine operational reactors offline and reducing the stable baseload buffer that ordinarily softens wind-dependent price swings.Weekly average baseload settled in the region of 88-90 £/MWh, a figure that understates the range buyers were exposed to on individual delivery days.Forward power contracts tracked gas movements.Q3-26 baseload closed the week near 104 £/MWh and Winter 2026 power held around 105 £/MWh.The gas-to-power spread remained tight, with electricity still pricing primarily off the gas curve rather than on renewable output assumptions.

Oil, Carbon and Global Commodities

Oil prices extended their recent gains over the week, with Middle East risk premium proving the dominant driver.Brent crude opened near $92/bbl on Monday and closed Friday around $97.50/bbl, a weekly gain of approximately 5.5%. WTI tracked broadly in line, settling near $95.50/bbl.The sustained strength in oil provided indirect support for European gas and power, reinforcing broader energy complex sentiment at a time when storage fundamentals alone would not have sustained the rally.EUA carbon permits posted their strongest weekly performance since early April, the December 2026 contract briefly trading above €80.50/tonne on Tuesday, a four-month high, before settling back to close near €79/tonne, a weekly gain of approximately 2.5–3%. TTF front-month gas closed the week near €50.20/MWh and JKM LNG front-month settled around $18.60/MMBtu.The persistent JKM premium continued to attract flexible LNG cargoes toward Asian buyers, limiting European terminal throughput.

Storage and Supply Outlook

European gas storage ended the week at approximately 41–42% of capacity, the slowest injection rate for early June in five years.The pace has been constrained by three concurrent factors: LNG cargoes being diverted toward Asia where the JKM premium remained commercially attractive, Norwegian maintenance outages reducing pipeline inflows at the start of the week, and above-average gas-for-power demand during the cooler early-week period.At this trajectory, reaching the 90% storage target by the end of the summer refill season would require a material acceleration in deliveries or a sustained reduction in competing demand.UK storage capacity remains structurally limited at around 3.1 bcm, sufficient for approximately 10 to 16 days of typical winter demand.This leaves the UK market more exposed than most European peers to any sustained tightening in supply or extended period of low LNG arrivals.The LNG send-out rate of approximately 9 mcm/day into UK terminals is well below full terminal capacity, with commercial incentives currently favouring Asian over European delivery for flexible cargo holders.The supply picture improved through the second half of the week as Norwegian nominations recovered and the British gas system moved back into surplus.The episode nevertheless reinforced how quickly fundamentals can shift: a single unplanned Norwegian outage combined with low wind would be sufficient to erase that surplus within days at current storage levels.

The Week Ahead – Procurement Outlook

UK energy markets head into the week of 9 June with geopolitics still firmly in the driver’s seat.Wholesale gas remains elevated and volatile, driven primarily by Middle East uncertainty, Norwegian maintenance schedules and LNG cargo routing decisions, factors that are difficult to model using traditional seasonal frameworks.Winter 2026 gas trading above 122p/therm represents a meaningful premium to contract levels seen earlier in the year.For businesses carrying significant unhedged winter exposure, the current forward curve implies real cost risk if Middle East tensions escalate further, Norwegian maintenance extends into the shoulder season, or European storage fails to accelerate its refill pace.These scenarios are plausible individually; the combination of more than one would likely push the curve materially higher.Businesses on flexible or index-linked tariffs should assess whether current forward prices justify locking in a proportion of winter volume for cost certainty.Those already carrying forward cover are well-positioned relative to today’s market levels. For businesses approaching contract renewal, the current volatility environment makes timing genuinely consequential.
