Following the turbulence seen earlier in the year, energy markets moved through summer 2025 with prices that appeared relatively steady on the surface. However, as with recent seasons, that stability masked a market still shaped by significant underlying risks. Prices remained highly sensitive to geopolitical developments, weather extremes and shifting global trade dynamics, keeping volatility firmly in play.
Geopolitics continued to be one of the most powerful drivers of market sentiment. Renewed tensions in the Middle East triggered sharp price reactions, with markets reminded how vulnerable global energy supply remains to disruption. Even with periods of de escalation, the risk of interruptions to key shipping routes particularly through the Strait of Hormuz has remained a persistent concern for both LNG and oil markets. At the same time, ongoing risks to Ukraine’s energy infrastructure raise the possibility of additional European gas demand, adding further strain to an already tight system.
Trade policy has added another layer of uncertainty. While recent cooperation between the US and EU helped ease some immediate concerns, the re emergence of tariff threats from the United States has unsettled markets. Proposals targeting countries trading with Russia have increased the risk of retaliation and broader trade tensions. On one hand, this could weaken global energy demand and apply downward pressure on prices. On the other, it creates unpredictability that markets struggle to price in with confidence.
The LNG market remains structurally tight. Reduced Russian gas flows, rising European demand and geopolitical risk have kept Europe heavily reliant on LNG imports. US LNG has become increasingly central, now supplying around a quarter of Europe’s gas needs. Encouragingly, European storage levels have improved, with injections on track to reach around 83 percent by the start of November. Despite this progress, the system remains exposed. Unplanned outages in Norway, stronger Asian demand during heatwaves, or weather related disruptions to US LNG infrastructure could quickly tighten balances again.
Weather has become an increasingly influential factor. Prolonged heat across Europe raises gas demand for cooling and threatens power supply by reducing nuclear output as cooling systems face temperature and transport constraints. Looking beyond Europe, the Atlantic hurricane season presents a clear risk to US LNG exports, a key pillar of European supply. While winter forecasts are still uncertain, early signs point to the potential for colder than average conditions later in the year, keeping forward looking risk firmly in focus.
Policy developments are also shaping longer term market expectations. In the UK, the decision to rule out zonal pricing under the REMA programme has provided some clarity, preserving a single national wholesale price. Further reforms remain on the horizon through to 2029, but this decision offers near term certainty for businesses planning procurement strategies. Meanwhile, carbon markets continue to tighten. The linking of UK and EU emissions trading schemes, combined with annual allowance reductions and policy driven supply constraints, has kept carbon prices elevated and increasingly influential on power pricing.
For businesses, the takeaway from summer 2025 is clear. While prices may not be making headlines every day, the market remains fragile. Geopolitics, trade policy, weather extremes, LNG dependency and tightening carbon markets all have the potential to shift prices quickly. In this environment, a proactive energy strategy remains essential to managing risk rather than reacting to it.
