European natural gas futures climbed in after-hours trading Friday as renewed violence in the Middle East and extreme heat across Europe tightened the outlook for energy markets.
The Dutch TTF front-month contract rose 4.262% to 42.25 euros ($48.44) per megawatt hour, while the UK NBP front-month contract gained 4.768% to 101.300 British pence ($1.34) per therm.
The price rise came after Israel continued strikes in Lebanon following the signing of a memorandum of understanding directed at finding an end to the conflict between the US and Iran earlier in the week.
While the Associated Press reported Friday that an unconfirmed truce had emerged, heavy exchanges of fire in southern Lebanon left at least 47 people dead, and four Israeli soldiers killed. The violence undermined a newly signed US-Iran memorandum of understanding and prompted the postponement of scheduled Friday negotiations.
The geopolitical shift followed a volatile week in which prices fell nearly 20% amid expectations that a US-Iran agreement could reopen the Strait of Hormuz and resume LNG flows from the Gulf, according to Trading Economics.
"A durable Hormuz reopening unwinds the single largest disruption; a relapse, or a slow Qatari restart, leaves Europe structurally tight into next winter," said David Duncan of Timera Energy in a Friday note.
Weather conditions added further upward pressure. A persistent high-pressure system is driving an intense heatwave across Europe, with meteorologists cited by The New York Times warning that temperatures could reach 37 degrees Celsius (98 degrees Fahrenheit) in northern Switzerland and issuing heat alerts in Germany. The UK Met Office has issued an amber warning for southern England and parts of Wales, with highs near 93 degrees Fahrenheit expected early next week. France, Spain, and Italy are forecast to exceed 104 degrees Fahrenheit in the coming days, unusually early for summer, with France already surpassing that level this week.
Atmospheric G2 said in a social media post Friday that river conditions across Europe are deteriorating as the heat intensifies, with uncertainty over when relief will arrive. Rising water temperatures in the Rhone and falling river flows are increasingly constraining French nuclear output, forcing temporary reductions in generation.
Montel reported that hotter weather is lifting German power prices as cooling demand rises, though strong sunshine is expected to boost solar generation to as much as 20% above normal.
The combination of geopolitical risk, weather-driven demand and supply-side constraints is complicating efforts to rebuild European gas inventories ahead of winter. Storage levels currently stand at 45.56% of capacity, down from 54.38% previously and roughly 14% below year-ago levels, according to Gas Infrastructure Europe. Levels are also well below the five-year average of 59.9%, according to the Swiss Federal Office of Energy. Trading Economics said net injections in June are tracking below seasonal norms.
