The US military said it intercepted what it called "unprovoked" Iranian attacks - including missiles, drones and small boats - and carried out self‑defence strikes as its ships were heading out of the Gulf through the strait.
The price of global oil benchmark Brent rose by 2.3% to $102.40 (£75.53) a barrel, while US-traded crude was 2.1% higher at $96.80.
The flare-up further endangers the US-Iran ceasefire, which President Donald Trump extended indefinitely on 21 April to allow more time for peace talks.
This week, Trump said that the war, which started on 28 February when the US and Israel attacked Iran, will be "over quickly" as Washington pushes for a framework for more detailed negotiations with Tehran.
Energy prices have surged since the start of the conflict after Iran threatened to attack ships in the critical Strait of Hormuz trade route in retaliation to the US-Israeli strikes.
More than a fifth of the world's oil and gas shipments usually pass through the waterway.
