European natural-gas prices resumed their advance after a two-session pullback as the market refocused on the risk of prolonged disruption to liquefied natural gas supplies. The Wall Street Journal reported that the benchmark Dutch TTF contract rose 2.4% to €73.63 per megawatt-hour, while Investing.com said the rebound lifted the market’s year-to-date gain above 160%. The move returned supply security to the foreground as Europe approaches the winter heating season with elevated prices.
The renewed buying followed President Donald Trump’s rejection of an Iranian truce proposal, according to the Wall Street Journal. That development reinforced concern that disruption around the Strait of Hormuz could last longer than traders had recently expected. The waterway is central to global energy flows, including LNG cargoes that help balance European supply after the region reduced its dependence on Russian pipeline gas.
Physical supply conditions added to the geopolitical concern. ANZ analysts cited by the Wall Street Journal pointed to ongoing maintenance on Norwegian pipelines and reduced LNG traffic through the Strait of Hormuz as sources of tightness in Europe. They also noted that stronger Chinese LNG demand could intensify competition for available cargoes in Asia, leaving Europe more exposed if import flows remain constrained during the winter build-up.
Inventories provide some protection but remain an important part of the market calculation. The Wall Street Journal put European Union gas storage at 70% of capacity. A separate Reuters report published a day earlier said German storage was at a historic seasonal low of 57%, even as VNG’s chief executive said Germany’s diversified import portfolio made supply more resilient than during the 2022 energy crisis. Reuters also reported that European gas prices had more than doubled in 2026 after reduced LNG availability linked to the closure of the Strait of Hormuz.
The latest rise comes after an already volatile month for European energy. Reuters reported on Tuesday that the Iran conflict had pushed European gas above €80 per megawatt-hour during September, the highest level since late 2022. That energy shock has also become a currency and interest-rate issue: higher imported fuel costs can add to inflation pressure while weighing on economic activity, and Reuters said analysts viewed softer gas prices as important for a renewed euro recovery.
What it means for traders: Natural Gas remains sensitive to headlines on Hormuz shipping, Norwegian maintenance and competition for LNG cargoes. Continued disruption or stronger Asian demand would keep Europe competing for limited supply, while restored shipping flows and the completion of maintenance would ease the physical tightness described by the sources. EUR/USD is also exposed because sustained energy costs can weaken Europe’s growth outlook and complicate the inflation picture at the same time.
The next signals to watch are Dutch TTF settlement prices, LNG traffic through the Strait of Hormuz, Norwegian pipeline availability and weekly European storage updates. Traders will also monitor whether the benchmark can sustain the rebound after two declining sessions and whether EU inventories continue to build before colder weather raises demand. Any change in the U.S.-Iran diplomatic track could quickly alter the supply-risk premium now embedded in European gas.
