Strait of Hormuz to reopen after agreement is signed, Trump says US President Donald Trump said the Strait of Hormuz will reopen following the formal signing of the memorandum of understanding between Washington and Tehran, clarifying earlier remarks that suggested the waterway would reopen immediately. Trump initially announced on Truth Social that an agreement had been reached with Iran and declared that the strait would be opened, telling global shippers to “let the oil flow”. However, the president later issued a follow-up statement indicating that the reopening would be delayed and would instead coincide with the formal signing of the agreement.
