A supply chain expert says ships won't immediately return to normal frequency through the Strait of Hormuz.

Iran and the US have accepted Pakistan's proposal to pause fighting two weeks, and Donald Trump's pulled back his extreme threat he'd obliterate Iran.

Wollongong University's Ethan Nikookar says insuring shipments will still be difficult.

"Insurers may still treat the area as high-risk, so that means higher premiums, limited coverage, and fewer ships will move to transit."
