European natural gas futures rose in after-hours trade on Wednesday after US President Donald Trump issued threats of further military action against Iran.
The Dutch TTF front-month contract gained 3.12% to 50.265 euros ($58.09) per megawatt-hour, while the UK NBP front-month contract was up 4.19% to 122.10 British pence ($1.64) per therm.
On Wednesday, Trump said the US will hit Iran "hard again today," while saying Iran "should sign the deal" and that the US wants one "that's meaningful and works." The televised comments came hours after Trump warned on Truth Social that Iran had taken too long to negotiate and would now have to "pay the price."
Prices rose prior to Trump's remarks after the US military carried out strikes on Iran in response to a downed helicopter on Tuesday, Trading Economics said, adding that these developments come after Israel and Iran agreed to suspend mutual attacks following a recent escalation in hostilities.
Meanwhile, the Strait of Hormuz remained closed for the 15th week running, hampering efforts to replenish European inventories ahead of winter.
Gas Infrastructure Europe puts current EU inventories at 42.80% of capacity, versus 51.79% this time last year.
Wood Mackenzie said in a note on Wednesday that European prices do not reflect the severity of the European storage situation. It said Europe's gas market, currently supported by weak demand, faces a tighter outlook than prices suggest due to inadequate storage injections and increasing competition for LNG. Low storage levels, combined with Asian LNG demand and high volatility, could lead to supply risks and shortages in the coming winter.
The consultancy said the market now hinges on three factors: a forward curve that does not fully reflect supply risks, a European balance dependent on weak demand, and intensifying global competition for LNG. Together, these factors suggest Europe's gas market is tighter than it appears and that prices may need to rise to restore equilibrium.
ANZ analyst Daniel Hynes said on Wednesday that LNG inflows into Europe have slowed in recent weeks, primarily due to stronger demand from major Asian markets. China's LNG imports rose from 8.4 million tonnes in April to 10.1 million tonnes in May, while increased gas-fired power generation in India has fueled a sharp uptick in LNG purchases. Weekly LNG imports into India surged by approximately 66% week-on-week as the country contends with an intense heatwave, with deliveries during June 1-7 running 88% higher than during the corresponding period in 2025.
