European natural gas futures declined further on Tuesday as renewed diplomatic efforts involving the US, Iran, Israel and Lebanon eased some concerns over potential supply disruptions and geopolitical risks.
The front-month Dutch TTF contract fell 5.516% to 55.040 euros ($62.76) per megawatt-hour, while the front-month UK NBP contract declined 4.646% to 134.220 British pence ($1.79) per therm.
Prices eased after US military strikes on Iran were paused last week, creating room for further negotiations between Washington and Tehran. Market sentiment was also supported by reports that Oman had advanced a proposal for the joint management and reopening of the Strait of Hormuz.
Adding to diplomatic momentum, Israel-Lebanon peace talks are expected to resume in Rome next week, multiple news outlets reported on Tuesday. However, regional risks remain elevated, with Israeli Prime Minister Benjamin Netanyahu meeting US President Donald Trump in Washington to discuss further strategic steps regarding Iran.
The decline in European gas prices could provide some relief for buyers seeking to rebuild storage levels ahead of the winter heating season. Gas inventories remain below historical norms, with storage facilities currently 55.66% full, compared with 66.83% at the same point last year, according to Gas Infrastructure Europe. Stocks are also below the five-year average of 71.5% for this period, data from the Swiss Federal Office of Energy showed.
Despite lower prices, Europe faces challenges in accelerating storage injections. Forecasts for another severe heatwave in August, with temperatures expected to exceed 40 degrees Celsius (104 degrees Fahrenheit) in parts of the region, could increase demand for cooling and boost power generation needs, potentially limiting the amount of gas available for storage replenishment.
