Front-End Contracts Rebound as Hormuz Risk Returns to Energy Markets

16th July 2026

UK energy markets moved higher over the past week as renewed conflict between the US and Iran brought geopolitical risk back to the forefront. Near-term gas and power contracts recorded the strongest increases, while further-dated prices remained comparatively stable. At the same time, another European heatwave is increasing electricity demand and placing additional pressure on power generation, giving energy buyers several risks to weigh up as they review their purchasing strategy for the months ahead. 

Geopolitical risk lifts the front of the curve 

The renewed escalation between the US and Iran from 7 July triggered a rapid market response. Gas and power prices rose across the front of the curve, reflecting concerns about further disruption to global energy supplies. 

UK day-ahead gas was 12.79% higher week on week, after rising by 2.52% during the previous trading session. August 2026 gas rose 12.15% across the week, while September 2026 increased by 11.48%. The Winter 2026 contract gained 10.84%. 

Power followed a similar pattern. Day-ahead electricity rose by 11.25% week on week and increased by 7.26% day on day. August 2026 and September 2026 rose by 11.15% and 10.56% respectively, while Winter 2026 increased by 10.20%. 

The reaction was concentrated in contracts closest to delivery. Further-dated gas contracts also moved higher, but the response across 2028 and 2029 was much smaller. This reflects the market outlook that immediate supply risks are more relevant to the coming months than to later years.  

Heat adds pressure to European power markets 

Europe is experiencing its third significant heatwave of the year, with high temperatures affecting France, Spain, Germany and the UK. Each period of extreme heat is adding to existing pressure on European power systems. 

Air-conditioning demand is increasing, while warmer rivers and dry conditions are making generation more difficult. French nuclear power stations depend on river water for cooling, meaning high water temperatures can restrict output. Drought conditions may also reduce hydroelectric power generation elsewhere in Europe.  

The UK has now seen three Electricity Margin Notices during the summer, including two in late June and another last week. These were the first summer notices of their kind and indicate that electricity supply margins can tighten even outside the traditional winter risk period.  

Longer term, greater use of electric vehicles, data centres and air conditioning will continue to raise electricity demand. Current expectations suggest there will be no significant additional baseload generation capacity before 2030, which could make periods of low renewable output or extreme temperatures increasingly important for future pricing.  

European Gas Storage Levels Support the Case for an Autumn Window 

European gas storage levels remain relatively low at around 52% of capacity. However, replenishment is progressing at more than one percentage point every three days. If this rate continues through July and August, storage levels could reach 70% to 80% or more by autumn.  

Forecasts for a mild Winter 2026 could  place downward pressure on prices later in the year. A developing Super El Niño may bring warmer conditions to parts of the Northern Hemisphere, and longer-range weather forecasts could begin influencing the market during autumn. 

This creates the possibility of a more favourable purchasing period once the summer’s immediate risks ease. Any improvement would still depend on continued storage injections and a reduction in Middle East tensions.  

Longer-term risks remain underpriced 

A mild winter is currently expected, but Europe has not yet experienced a severely cold winter without significant Russian pipeline gas. A one-in-ten year cold winter could produce a much stronger price response, particularly if LNG supplies from Qatar become disrupted. 

Extreme heat creates a separate risk for Summer 2027 and beyond. Higher demand could coincide with restrictions on nuclear or hydro generation, adding volatility to contracts that currently remain well below the front of the curve.  

Traders’ View 

The latest increases once again illustrate how quickly near-term prices can respond when geopolitical risk returns. However, lower rates remain available further along the curve, particularly across 2028 and 2029. 

Businesses with unhedged energy positions or contracts approaching renewal should consider putting agreements in place now, allowing initial hedges to be secured while retaining access to any autumn price weakness. A flexible strategy can delay selected purchases if markets fall, while further-dated volume bought at lower rates may be sold back during future price spikes.  

This reduces the risk of being forced to purchase when an existing contract is close to expiry. It also provides greater control over when volume is fixed.

FAQ: 

What is geopolitical risk? 

Geopolitical risk is the possibility that political tensions, conflict, sanctions or changes in international relations could disrupt energy supply and detrimentally affect prices. For UK businesses, this can lead to sudden volatility in gas and power markets as seen these past few months or during the 2022 crisis. 

What tools help with geopolitical risk monitoring? 

Businesses can monitor geopolitical risk through wholesale market updates, trading desk commentary and direct support from energy traders. This helps decision makers better understand how global events might affect gas and power prices, then adjust purchasing decisions accordingly. 

How does geopolitical risk affect energy prices? 

Geopolitical risk can trigger a rise in energy prices when conflict, sanctions or political instability threaten supply routes or major oil and gas producing regions. Global markets often react quickly to the possibility of disruption, increasing volatility in UK gas and power contracts. 

Why do front-end contracts react first? 

Front-end contracts are closest to delivery, so they are more exposed to immediate changes in supply, demand and market conditions. When disruption occurs, buyers and traders quickly reprice these contracts because there is less time for the market to adjust. 

What do European gas storage levels mean for autumn prices? 

Higher European gas storage levels can reduce concerns about winter supply and may place downward pressure on autumn prices. If storage remains low or replenishment slows, the market may be subject to a risk premium, making contracts more expensive.
