LONDON: ​Benchmark Dutch and British wholesale gas prices soared by almost 50 percent on Monday, after major liquefied natural gas exporter Qatar Energy said it had halted production due to attacks in the Middle East.

Qatar, soon to cement its role as the world’s second largest LNG exporter after the US, plays a major role in balancing both Asian and European markets’ demand of LNG.

Most tanker owners, oil majors and ‌trading houses ‌have suspended crude oil, fuel and liquefied natural ​gas shipments ‌via ⁠the ​Strait of ⁠Hormuz, trade sources said, after Tehran warned ships against moving through the waterway.

Europe has increased imports of LNG over the past few years as it seeks to phase out Russian gas following Russia’s invasion of Ukraine.

Around 20 percent of the world’s LNG transits through the Strait of Hormuz and a prolonged suspension or full closure would increase global competition for other ⁠sources of the gas, driving up prices internationally.
