European natural gas futures rallied on Monday as renewed fighting in the Middle East reignited concerns over potential disruptions to LNG flows through the Strait of Hormuz.
Front-month Dutch TTF futures rose 4.66% to 70.100 euros ($81.27) per MWh, while the UK markets were closed due to a Summer bank holiday on Monday.
This comes after the US resumed attacks against Iran, for the first time in weeks, targeting two of its rocket launchers located on Larak Island, according to a report by Al Jazeera.
Iran's Revolutionary Guard Corps confirmed the attacks, noting that several Iranian civilians and fighters were killed and injured. In retaliation, Tehran said that it had attacked US bases in Jordan and military targets at the Al Minhad airbase in the UAE.
Iran's President Masoud Pezeshkian said that Tehran was "not looking for war," but added that the country would not "sit still in the face of any aggression."
Meanwhile, traffic along the strategically crucial Strait of Hormuz, which accounted for one-fifth of global LNG flows, held steady with 19 transits on Sunday, according to ShipFinder.
Daniel Hynes, senior commodity strategist at ANZ, noted that the prospect of Qatari gas flows resuming soon looked increasingly bleak, following QatarEnergy's extended "force majeure" for another month, owing to persistent uncertainties surrounding the Strait of Hormuz.
This comes amid record-low gas inventories for this season across Europe, at just 64.73% of capacity, compared to 77.09% 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 81.7%, according to the Swiss Federal Office of Energy.
Gas supply concerns remained elevated across the region ahead of the upcoming winter, even as Germany's Minister for Economic Affairs and Energy, Katherina Reiche, sought to ease fears by pointing to a sharp increase in flows into storage facilities in recent days.
