Europe's Carbon Market Hits Eight-Month High as Middle East Conflict Drives Gas and Oil Higher
The Dec 2026 EUA contract surged to a near eight-month high as Middle East supply fears drove gas and crude higher, with European storage below seasonal norms.
Europe's benchmark carbon price hit a near eight-month high on Monday (2026-09-14) as the Dec 2026 EUA contract tracked a broad energy complex rally driven by new Middle East supply fears, Montel reported. The contract was at €87.63 per tonne of CO2 in early European trading on Tuesday (2026-09-15), holding close to those highs.6
The move has carried the wider energy complex with it. ICE Brent crude front-month was at $109.08 a barrel on Tuesday (2026-09-15), up 0.59%, and ICE Endex TTF front-month gas was at €82.95 per megawatt-hour, both elevated by escalating concerns over flows through the Strait of Hormuz.6
EUAs follow gas prices through the power generation stack. When TTF rises, coal becomes cheaper to burn relative to gas on a carbon-adjusted basis, shifting the generation mix and lifting demand for permits. German power was at €172.45 per megawatt-hour on Tuesday (2026-09-15), reflecting the pass-through from both elevated gas costs and rising carbon prices.6
The Hormuz chokepoint is central. Around 20% of global LNG traffic passes through the waterway, with Qatar a major exporter, meaning any sustained disruption hits European import volumes directly. LNG accounts for roughly a quarter of Europe's total gas supply, according to Chris Wheaton, oil and gas analyst at Stifel — enough that a prolonged Hormuz blockage would force buyers to draw harder on storage through winter.5,1
Goldman Sachs estimated in May (2026-05-19) that a pause in Middle East LNG flows would reduce near-term global LNG supply by about 19%, CNBC reported. That week, ICE Endex TTF front-month had already climbed 35% in a single session to above €60 per megawatt-hour and was up 76% on the week. The market has moved substantially higher since then.1
It has also reversed sharply before. European gas prices fell 8.6% in Amsterdam on Monday (2026-07-27) after Washington paused its Iran strikes and Tehran signalled a halt to retaliatory attacks, Oilprice.com reported. The 2026 pattern has been consistent: escalation drives spikes, any de-escalation signal brings quick liquidation. That dynamic has not been removed from the current rally.2
Market participants warned Montel in the week of 2026-08-31 that gas prices, then already at multi-year highs, were vulnerable to a sharp correction if bearish news emerged. "The risk is that prices keep going up speculatively," one source told Montel. ICE Endex TTF front-month topped €70 per megawatt-hour on Monday (2026-08-31) after US-Iran hostilities re-escalated — a 5% single-session gain that illustrated how quickly geopolitical sentiment translates into commodity prices.4,3
Europe's storage position removes a key cushion. Gas Infrastructure Europe data showed underground storage at approximately 64% of capacity in early September, below the five-year seasonal average with the summer injection period nearing its end. Buying gas to close that gap at TTF above €82 per megawatt-hour is expensive, and it compounds the vulnerability of carbon prices to any further supply tightening.5
Storage at 64% leaves European buyers with little buffer if Hormuz flows tighten further. The pace of injection from here, constrained by high TTF prices and uncertain LNG availability through the Strait, shapes the EUA floor into winter — and both are hostage to the next move in the Middle East.5,6
