Natural gas prices across Europe and the United Kingdom rose sharply on March 11, 2026, as fears grew that ongoing tensions in the Middle East could disrupt energy supplies. According to Al Jazeera, the increase followed unverified reports that Iran had begun placing mines in the Strait of Hormuz, one of the world’s most critical routes for oil and gas transport.

Market analysts noted that any disruption in the strait could significantly affect liquefied natural gas (LNG) deliveries to Europe and Asia. During morning trading, European gas prices climbed by about 5.7 percent, while the UK’s main wholesale gas contract rose nearly 6 percent. The situation intensified after the US Central Command announced that American forces had “eliminated” 16 Iranian vessels allegedly involved in mine-laying near the waterway.

Analysts warned that further deterioration of security in the Strait of Hormuz could have major consequences for global energy markets, heightening international concerns over Middle East stability and supply reliability.
