European natural gas markets whipsawed this week as diplomatic headlines from the United Nations General Assembly drove sharp repricing of Middle East supply risk. On Tuesday, the Dutch TTF front-month contract, Europe’s benchmark, rose about 1.6% to around €78.80 per megawatt-hour, while the British NBP contract traded near 195.40 pence per therm. The rebound followed a more than 7% slump on Monday, the steepest one-day decline in nearly two months.
The initial sell-off was triggered by reports that U.S. President Donald Trump was open to direct talks with Iranian President Masoud Pezeshkian at the UN General Assembly. Traders interpreted the possibility of diplomacy as reducing the risk of disruptions to the Strait of Hormuz, a critical chokepoint for global energy flows. By Tuesday morning, however, that optimism had cooled, as market participants recognized a breakthrough was far from certain and physical supply through the Persian Gulf remained constrained.
Brent crude futures also edged lower after a 3% drop in the previous session. Reports indicated energy companies and shipping operators were using overland pipelines and alternative loading routes off the coast of Oman to bypass Gulf transit issues, adding to downward pressure on prices alongside the diplomatic developments.
Europe’s supply picture remains fragile. Germany’s latest gas-storage tenders sought lower-than-expected volumes, but overall storage levels are historically low heading into the winter heating season. The European Central Bank has warned that wholesale gas price spikes now feed through to retail inflation within one to three months across more than half of eurozone economies.
By Wednesday, benchmark Dutch front-month TTF gas slipped about 0.6% to €72.90 per megawatt-hour, near its lowest level since early September, while British wholesale gas remained close to multi-week lows. Iran told Reuters it could reopen the Strait of Hormuz within seven days if the United States eased military pressure and lifted its blockade on Iranian ports. However, Tehran later rejected claims that it was ready to reopen the strait, calling them “false, unreliable and lacking in accuracy,” according to The Hormuz Letter.
Saudi Arabia separately restarted operations at its East-West oil pipeline, which can move crude to the Red Sea while bypassing Hormuz, offering another potential source of supply relief. Still, any reopening of Hormuz remains conditional, and previous diplomatic efforts have produced repeated starts and stops.
European gas storage is around 70% full, materially below normal seasonal levels. Limited flows through Hormuz have already restricted some LNG exports, particularly from Qatar, while Norwegian maintenance has constrained European pipeline supply. Lower gas and oil prices could ease inflation pressure and influence expectations for European interest rates, but another supply shock could strengthen the case for restrictive monetary policy. For now, traders are pricing in a greater chance of improved Middle East energy flows, while low storage keeps the market highly sensitive to winter weather and geopolitical developments.
