US Market Drivers

Investor sentiment was largely driven by the outcome of the U.S.-Iran peace talks. Stock futures in the U.S. ticked higher after-hours following President Donald Trump’s announcement of an extended ceasefire with Iran. However, the president said that despite the extension, military blockade in the Strait would continue.

"Based on the fact that the Government of Iran is seriously fractured, not unexpectedly so and, upon the request of Field Marshal Asim Munir, and Prime Minister Shehbaz Sharif, of Pakistan, we have been asked to hold our Attack on the Country of Iran until such time as their leaders and representatives can come up with a unified proposal," Trump said in a post on Truth Social.

"I have therefore directed our Military to continue the Blockade and, in all other respects, remain ready and able, and will therefore extend the Ceasefire until such time as their proposal is submitted, and discussions are concluded, one way or the other,” he added.

Meanwhile, Iran has reportedly said that it won’t attend the talks with the U.S., calling it a “waste of time.” Previously, Iran asked the United Nations to intervene in the matter related to the seizure of one of its vessels in the Strait of Hormuz, calling the move by the U.S. "a clear and material breach" of the ceasefire between the nations, while also demanding that the U.S. release the vessel, the crew, and the families captured aboard.
