European natural gas futures rose about 1.6% on Tuesday after falling more than 7% in the previous session, as markets reassessed the prospect of diplomatic engagement between U.S. President Donald Trump and Iran’s President Masoud Pezeshkian. The TTF front-month Dutch contract, Europe’s primary gas benchmark, reached approximately 78.80 euros per megawatt-hour, while Britain’s NBP contract climbed to roughly 195.40 pence per therm. Reports that President Trump was willing to hold discussions with Pezeshkian during this week’s UN General Assembly meetings in New York initially reduced concern about supply disruptions through the Strait of Hormuz, a major energy transit corridor. That optimism weakened as traders recognized that meaningful progress remains uncertain and physical constraints affecting Persian Gulf routes continue. Energy producers and maritime operators are using overland pipelines and alternative loading facilities along Oman’s coastline to bypass Gulf transit challenges. Germany’s latest gas-storage tender delivered less volume than markets expected, adding bearish pressure, but national storage remains well below historical norms ahead of the winter heating season. The European Central Bank has warned that wholesale gas-price increases feed into consumer inflation within one to three months in more than half of eurozone economies. Markets are now watching developments from New York, where any substantive U.S.-Iran diplomatic update could generate significant volatility in either direction.
