US natural gas futures rose to $2.84 per MMBtu on Monday but remained close to their lowest level since August 2025, as mild spring weather continued to suppress demand and allow storage levels to build. The latest EIA data showed a 36 Bcf injection for the week ending March 27, compared with a five-year average withdrawal of 4 Bcf. Meanwhile, President Donald Trump on Sunday issued an ultimatum to Iran, threatening to strike Iranian oil facilities and other civilian infrastructure if the Strait of Hormuz is not reopened. Tehran, however, rejected the demand, heightening fears of prolonged supply disruptions. Despite the tensions, US natural gas remain largely insulated from an overseas supply shock, as domestic export terminals are already operating near maximum capacity.
