European natural gas prices reached their highest level since early 2023 as escalating Middle East attacks continued to disrupt liquefied natural gas shipments through one of the world’s most important transit routes. Front-month Dutch TTF futures, Europe’s benchmark, rose 3.8% on Wednesday to 78.72 euros per megawatt-hour. The increase lifted monthly gains above 40%, while prices were on track for their highest close since the end of 2022.
