08:54 AM EDT, 04/13/2026 (MT Newswires) -- US equity futures were lower pre-bell on Monday after President Donald Trump ordered a blockade of the Strait of Hormuz following the failure of US and Iran to reach an agreement in peace talks in Islamabad.

Dow Jones Industrial Average futures were 1% lower, S&P 500 futures were down 0.6%, and Nasdaq futures were 0.6% lower.

"Effective immediately, the United States Navy, the Finest in the World, will begin the process of BLOCKADING any and all Ships trying to enter, or leave, the Strait of Hormuz," Trump said in a post on Truth Social on Sunday.

Trump said that an agreement was not reached due to Iran's unwillingness to give up its nuclear ambitions, while Iran said the US had made unreasonable demands.
