The United States and Iran announced on Sunday that they had struck a preliminary agreement to end their war, raising hopes for an end to the energy crisis that has gripped countries worldwide since the conflict began.

"Ships of the World, start your engines. Let the oil flow!" President Donald Trump wrote in a social media post hailing the US-Iran agreement.

The deal is set to reopen the Strait of Hormuz once both sides formally sign the accord on Friday.

The narrow waterway is a crucial route for global energy trade, handling about a fifth of the world's oil and natural gas in normal times.

Tehran has effectively shut shipping through the strait since the onset of the conflict on February 28, 2026, causing one of the largest global oil-supply disruptions in history.
