European natural gas prices experienced a sharp increase, reaching €51.4/MWh, as escalating conflict in the Middle East disrupted key energy infrastructure and shipping routes. Intensified attacks over the weekend, particularly targeting Persian Gulf oil assets, contributed to heightened market uncertainty. The closure of critical transit routes removed around 20% of global supply from circulation, raising concerns over energy security and triggering expectations of stronger competition for LNG ahead of the summer replenishment season.
TTF gas futures displayed significant volatility during the second week of March. On March 9, prices surged to €56.453/MWh, marking a 5.7% daily increase compared to the previous session, driven by renewed geopolitical tensions and tightening supply expectations. However, on March 10, prices dropped sharply to €47.393/MWh (-16.00%), the week’s lowest level, following announcements that suggested a potential de-escalation of the conflict. This relief was short-lived, as prices rebounded on March 11, rising by 5.5% to €49.989/MWh. The market continued to stabilize on March 12, edging up to €50.87/MWh (+1.8%), before ending the week with minimal movement on March 13 at €50.115/MWh (-1.5%). Overall, the weekly average stood at €50.96/MWh, reflecting a modest increase of 1.2% despite intra-week fluctuations. At the time of reporting, the one-month forward contract was trading around €51.000/MWh ($16.30/MMBtu).
Europe continues to operate in the aftermath of the major energy shock triggered by Russia’s invasion of Ukraine in 2022. In response, the European Union has accelerated efforts to expand renewable energy capacity while diversifying gas supply sources following the reduction of Russian pipeline flows. Although these measures have improved diversification, the system remains structurally exposed to global fossil fuel markets, particularly in times of geopolitical disruption. The current US–Iran conflict introduces an additional layer of uncertainty, reinforcing concerns over supply security and price stability.
At the policy level, these developments have renewed focus on energy resilience and the transition toward cleaner energy systems. European Commission President Ursula von der Leyen has emphasized the importance of accelerating investment in domestically produced, low-carbon energy sources, highlighting the need to reduce dependency on volatile external supply chains while maintaining affordability and sustainability objectives.
Market dynamics are already reflecting the impact of geopolitical tensions. Disruptions in the Middle East have tightened global LNG availability, with estimates suggesting that around 1.5 million tonnes per week (approximately 2.2 bcm), or nearly one-fifth of global LNG exports, have been affected. This tightening of supply has pushed European benchmark prices higher, with TTF day-ahead prices exceeding €55/MWh in early March, partly due to reduced exports from major suppliers such as Qatar.
The increase in gas prices has had a pronounced effect on electricity markets across Europe. Despite substantial growth in renewable generation—adding more than 300 TWh between 2022 and 2025—gas-fired plants continue to play a key role in setting marginal electricity prices. As a result, fluctuations in TTF gas prices are rapidly transmitted into power markets, meaning that even relatively small supply disruptions can lead to significant increases in wholesale electricity prices.
At the same time, Europe’s ability to mitigate such shocks through fuel switching has diminished. Coal-fired generation capacity has declined in recent years, while environmental policies have further restricted its use as a backup option. Consequently, the system now exhibits reduced short-term flexibility, limiting its capacity to offset spikes in gas prices through alternative generation sources.
Demand-side factors have so far helped partially cushion the impact of supply disruptions. Gas consumption across Europe has been running approximately 14% below seasonal norms, resulting in an estimated reduction of around 2.5 bcm since early March. This decline has temporarily offset a portion of the lost LNG supply, easing pressure on global balances and helping to stabilize prices in the short term.
However, this balancing effect may not persist. European gas storage levels are currently lower than in the previous year following a colder winter, leaving the system with a smaller buffer heading into the upcoming replenishment season. As a result, any prolonged supply disruption or unexpected increase in demand could quickly reverse recent stability and reintroduce upward price pressure.
In conclusion, while Europe has made meaningful progress in diversifying its energy mix and expanding renewable capacity, its exposure to gas price volatility remains significant due to the structure of its energy markets. The current geopolitical situation highlights the ongoing need to strengthen system resilience through increased storage capacity, improved demand-side flexibility, and continued investment in low-carbon technologies to reduce vulnerability to external shocks.
