Asia-Pacific markets were set to open broadly higher Tuesday as oil prices, while elevated, eased slightly following news that President Donald Trump was postponing a scheduled attack on Iran.

Trump said in a Truth Social post that U.S. military leaders were informed to call off a "scheduled attack of Iran tomorrow" after requests from the leaders of Qatar, Saudi Arabia and the United Arab Emirates.
"A Deal will be made, which will be very acceptable to the United States of America, as well as all Countries in the Middle East, and beyond. This Deal will include, importantly, NO NUCLEAR WEAPONS FOR IRAN!," Trump added.
However, Trump cautioned that he has informed his military leaders "to be prepared to go forward with a full, large scale assault of Iran, on a moment's notice, in the event that an acceptable Deal is not reached."
Despite the fragile ceasefire between the U.S. and Iran, the vital Strait of Hormuz remains closed by Tehran, while the U.S. continues to blockade Iranian ports.
"As the Middle East conflict enters its third month, there is little prospect of a swift and durable settlement between the U.S. and Iran and with it the full reopening of the Strait of Hormuz," Moody's said in a note.
