US stock futures were mixed Monday evening, with some investors showing hope for a resolution to the US-Israeli war against Iran ahead of an upcoming deadline for the opening of the Strait of Hormuz.

Contracts linked to the S&P 500 (ES=F) and Nasdaq 100 (NQ=F) edged up 0.1%, while Dow futures (YM=F) slipped roughly 0.1%.

Earlier in the day, stocks finished in positive territory. The S&P 500 (^GSPC) advanced nearly half a percent, the Nasdaq Composite (^IXIC) posted a similar gain, and the Dow Jones Industrial Average (^DJI) climbed more than 160 points.

Markets are closely tracking developments in the Middle East. Trump has given another 48-hour deadline for Iran to reopen the Strait of Hormuz, set to expire Tuesday evening. Trump issued the deadline via Truth Social in an erratic post stating “Open the F*****’ Strait, you crazy bastards, or you’ll be living in Hell – JUST WATCH! Praise be to Allah”. A proposal for peace, reportedly backed by Pakistan, is under consideration in negotiations between the US and Iran.

Investor sentiment appears to reflect cautious optimism that tensions may ease in the near term, helping explain Monday’s market gains. Trump issued a statement on Monday claiming “Unfortunately, the American people would like to see us come home” in relation to the length of the war in Iran. Traffic in the Strait has increased this week, alleviating some pressures for oil, with China and Japan receiving the largest number of tankers.

Looking ahead for the week, traders will be focused on preliminary figures for February durable goods orders, due Tuesday morning, as well as US inflation data due out Friday. Earnings results from Delta (DAL) highlight reports for the week, expected Wednesday.
