US natural gas futures rose to $2.84 per MMBtu on Monday but stayed near their lowest level since August 2025, as mild spring weather continued to curb demand and support inventory builds. The latest EIA data reported a 36 Bcf injection for the week ending March 27, in contrast to a five-year average withdrawal of 4 Bcf for the same period.
At the same time, President Donald Trump on Sunday issued an ultimatum to Iran, threatening strikes on Iranian oil facilities and other civilian infrastructure if the Strait of Hormuz is not reopened. Tehran rejected the ultimatum, intensifying concerns over prolonged supply disruptions.
Despite the escalating geopolitical tensions, the US natural gas market remains largely shielded from overseas supply shocks, as domestic export terminals are already operating close to maximum capacity.
