Global oil prices jumped more than 2% in the latest trading as markets reacted to a fresh United States military strike against Iranian launchers on Larak Island, bringing renewed geopolitical risk directly back into one of the world’s most important energy corridors.

Brent crude climbed back above $90 a barrel, rising approximately 2.5% to around $90.32 during early Monday trading, while US West Texas Intermediate crude gained roughly 2.4% to around $85.41.

The sudden move followed confirmation that US forces struck two Iranian launchers on Larak Island, which sits inside the strategically critical Strait of Hormuz.

According to the US account of the operation, members of Iran’s Islamic Revolutionary Guard Corps had been observed preparing launchers capable of firing rockets carrying sea mines into the strait.

The United States said its forces attacked the launch systems before those weapons could be deployed.

Iran’s Revolutionary Guards subsequently confirmed that the island had been struck and said soldiers and civilians had been killed or injured, although an exact casualty figure was not immediately provided.

The IRGC also promised what it described as a response and punishment, creating immediate concern that the confrontation could trigger another cycle of retaliation.

For energy markets, the location of the confrontation is particularly important.

The Strait of Hormuz connects the Persian Gulf with the Gulf of Oman and the wider global shipping network. Enormous quantities of crude oil and liquefied natural gas exported by Middle Eastern producers travel through the waterway.

Even when oil itself continues flowing normally, the possibility of disruption can push prices sharply higher because traders begin pricing additional risk into future supply.

Sea mines represent an especially serious concern.

Unlike conventional missile attacks against a clearly identified target, mines can make shipping lanes dangerous for extended periods and require specialised naval operations to locate and remove them.

Commercial shipping companies also can respond to heightened threats by delaying journeys, changing routes where possible or demanding additional insurance protection.

Those costs ultimately can influence the price of transported energy.

The latest confrontation comes after US forces recently completed efforts to clear mines from the strait’s main shipping channel, making Washington particularly sensitive to any indication that Iran could attempt to deploy additional devices.

The American strike therefore appears designed partly to prevent another disruption before it develops.

Markets now will be watching Tehran’s response extremely closely.

A limited Iranian reaction could allow oil prices to stabilise after the initial jump.

A larger military response involving shipping, US forces or regional energy infrastructure could send crude significantly higher.

That matters far beyond financial markets.

Higher oil prices eventually can increase petrol and diesel costs, airline expenses, manufacturing costs and transportation charges.

Countries heavily dependent on imported energy can experience additional inflation and currency pressure.

Central banks also face greater difficulty controlling prices when geopolitical events suddenly increase energy costs.

The latest oil move therefore represents more than traders reacting to another military headline.

It reflects renewed fear surrounding the security of the Strait of Hormuz itself.

With Brent again above $90 and Iran threatening retaliation, global markets increasingly are waiting to see whether the latest US strike remains an isolated operation or becomes the beginning of another dangerous escalation.
