Global oil prices climbed above $100 per barrel on Monday as tensions in the Middle East continued to rattle energy markets and diplomats worked to secure safe passage for oil tankers through the Strait of Hormuz.

The surge in crude prices followed comments from Donald Trump, who revealed that US forces had carried out military strikes on Kharg Island, a key facility in the Gulf that handles the majority of Iran’s oil exports.

Trump warned that the attacks could be extended to other energy infrastructure if Iran attempts to disrupt shipping in the Strait of Hormuz.

The vital shipping route has reportedly been shut since the US-Israeli offensive against Iran began on February 28, raising concerns about global oil supply.

Trump also urged other nations to contribute naval forces to safeguard the passage, though he did not outline specific commitments from the United States. He suggested that countries including China, France, Japan, South Korea, and the United Kingdom should take part in efforts to secure the waterway.

In a post on Truth Social, Trump said countries that rely on oil shipments through the Strait of Hormuz must take responsibility for protecting the route, adding that the United States would provide significant support.

He also noted that safeguarding the strategic passage should have always been a joint international effort.
