Asia-Pacific markets set to open lower as investors assess latest U.S.-Iran signals

Asia-Pacific markets were set to open lower Tuesday as investors weighed developments in U.S.-Iran negotiations.

U.S. President Donald Trump and his national security team on Monday discussed Iran's reported offer to reopen the Strait of Hormuz, contingent on the U.S. lifting its blockade and ending the conflict, according to White House press secretary Karoline Leavitt.

It remains unclear whether Trump, who has said sanctions relief would come only once a deal is "100% complete," is willing to consider the proposal as a pathway to de-escalation in the two-month-long conflict.

"I will confirm the president has met with his national security team this morning," Leavitt said at a press briefing Monday afternoon when asked about the reports.

Japan's Nikkei 225 was poised to fall after notching a record high yesterday, with the Chicago futures contract at 60,395 and its Osaka counterpart last trading at 60,200 compared with the index's previous close of 60,537.36.

Similarly, Hong Kong Hang Seng index futures were at 25,875, lower than the index's last close of 25,925.65.

In Australia, futures last traded at 8,720 compared to the S&P/ASX 200's last close at 8,766.4.

U.S. futures edged higher, with Dow Jones Industrial Average futures adding 0.12%, or 57 points. S&P 500 futures rose 0.14%, while Nasdaq 100 futures added 0.15%.

Overnight in the U.S., the S&P 500 and the Nasdaq Composite rose to new record highs but gains were limited as stalled Iran peace talks and a fresh escalation in the Strait of Hormuz pushed oil prices higher.

The broad market index added 0.12% and closed at a record level of 7,173.91. The Nasdaq Composite gained 0.20% and notched a closing record of 24,887.10. Both indexes also reached new all-time highs in the session. The Dow Jones Industrial Average fell 62.92 points, or 0.13%, to settle at 49,167.79.
