On Wednesday, Mohammad Reza Naqdi, a general in Iran's Islamic Revolutionary Guard Corps, said that Tehran could prolong its war with the US until President Donald Trump's term is scheduled to end on January 20, 2029, while speaking to US broadcaster PBS.
Earlier this week, Trump demanded in a Truth Social post that Tehran compensate the US for lives lost and property damaged during Iran's bombing campaign in recent months.
The demand came in response to Tehran's own calls for compensation from Washington, signaling a stalemate between the two sides.
Traffic along the Strait of Hormuz, which accounted for one-fifth of global LNG flows, dropped to 10 on Wednesday, according to ShipFinder.
According to Daniel Hynes, a senior commodity strategist at ANZ, the prospects of a "colder-than-normal winter" are raising concerns surrounding Europe's low gas inventory levels. Hynes also highlighted China's low river and dam levels due to the El Nino heatwaves, which he said could add to the country's natural gas demand, making things worse for Europe.
European gas inventories stood at 59.32% of capacity, compared to 72.31% during the corresponding period a year ago, according to Gas Infrastructure Europe.
Inventories were also significantly below the five-year average for this period, at 76.5%, according to the Swiss Federal Office of Energy.
