Global oil prices climbed after the United States launched fresh strikes on Iran, raising fears of a wider conflict and creating new uncertainty over the security of the Strait of Hormuz, a key route for global energy supplies.

Brent crude oil rose nearly 1 percent to around $79 per barrel, while US West Texas Intermediate (WTI) crude gained about 1 percent to trade at $74.37 per barrel. UAE Murban crude recorded an even sharper rise of 6.67 percent, reaching $74 per barrel.

Oil prices had already moved higher after US President Donald Trump warned of possible further action against Iran. The latest military strikes added to market concerns, helping both major oil benchmarks reach their highest levels in more than two weeks.

The US military said the new operation was aimed at keeping the Strait of Hormuz open for international shipping. However, analysts believe the renewed tensions have weakened hopes for a lasting end to the conflict and increased risks for vessels passing through the strategic waterway.

According to reports, the strikes came after attacks on three oil tankers moving through the region. The incidents have prompted shipping companies and insurers to reassess security risks.

Insurance industry sources said some firms have advised shipping operators to temporarily avoid the Strait of Hormuz, while others are reviewing coverage policies due to growing war-related concerns.

Meanwhile, Iran claimed it targeted US military facilities in Bahrain and Kuwait in response to the attacks. The escalating tensions have fueled concerns that any disruption in oil shipments could further push up global energy prices in the coming days.
