European natural gas prices moved lower on Monday, following a retreat in oil markets after reports surfaced that the United States had discussed a temporary waiver of sanctions on Iranian crude. Traders also factored in milder temperatures and robust renewable output that together helped to dampen gas demand.
The Dutch front-month contract at the Title Transfer Facility - the TTF benchmark - was last down 2.4% at 48.975 euros per megawatt hour, according to ICE data. Earlier in the trading session the contract had reached its highest point since April 7 before reversing course.
Across the North Sea, the British June contract slipped 2.7%, trading at 120.23 pence per therm.
Market participants noted that many liquefied natural gas and pipeline gas deals are indexed to oil prices, so shifts in crude valuations frequently feed through into gas pricing. In this instance, crude futures turned lower after Iranian media reported that the U.S. had proposed a temporary waiver of oil sanctions on Iran until a final peace agreement between Washington and Tehran is secured.
Political signals added another layer of complexity. Ahead of a meeting of Group of Seven finance ministers, Treasury Secretary Scott Bessent said he would urge officials to maintain U.S. sanctions on Iran aimed at preventing financing from reaching Tehran. Separately, U.S. President Donald Trump posted on social media that "the clock is ticking" for Iran to achieve a peace deal.
Geopolitical tensions remained present over the weekend. A drone strike caused a fire at a nuclear facility in the United Arab Emirates, and Saudi authorities reported intercepting three drones. Those incidents raised questions about the durability of an already fragile ceasefire between the U.S. and Iran.
At the same time, near-term demand factors provided downward pressure on gas requirements. A short-term uptick in temperatures combined with solid output from renewable sources to temper consumption, moderating the upward pressure on gas prices.
Overall, the picture for European gas on Monday was shaped by the interplay of oil-linked contract mechanics, shifting geopolitical headlines related to Iran and a modest easing of demand drivers.
