European natural gas futures were rallying on Tuesday after the US-Iran ceasefire expired without making any progress, and a projectile struck a vessel transiting the Strait of Hormuz.
Front-month Dutch TTF futures rose 1.55% to 62.715 euros ($72.57) per megawatt-hour, while UK NBP futures gained 1.61% to 155.000 British pence ($2.10) per therm.
US President Donald Trump said that he wasn't seeking an extension of the ceasefire, while calling on Tehran to surrender instead. Trump said Iran should "wave the right flag of surrender," in an interview with Fox News on Monday.
Meanwhile, a commercial vessel transiting through the Strait of Hormuz was struck by an unknown projectile early on Tuesday, according to the UK's Maritime Trade Operations, adding to the heightened tensions across the region.
Traffic along the strategically crucial strait, which accounted for one-fifth of global LNG flows, stood at 18 on Monday, according to data from ShipFinder.
Daniel Hynes, a senior commodity strategist at ANZ, once again highlighted the intensifying competition between Europe and Asia for LNG cargoes, especially with the former entering winter with significantly below-average gas inventory levels.
European gas inventories stood at 61.11% of capacity, compared to 73.63% during the corresponding period a year ago, according to Gas Infrastructure Europe.
Inventories were also significantly below the five-year average for this period, at 78.1%, according to the Swiss Federal Office of Energy.
