Trump Says US, Iran Agree to 2-Week Halt in Attacks; Samsung Up 6%, SK Hynix 9% Premarket

Samsung Electronics Co. and SK Hynix Inc. surged in premarket trading after the US said it had agreed with Iran to a mutual two-week halt in military action.

As of 4:04 a.m. on Aug. 8, Samsung Electronics was up more than 6% from the previous session on the NextTrade (NXT) premarket, while SK Hynix had jumped more than 9%.

With a little more than an hour left before his self-imposed negotiation deadline, President Donald Trump wrote on Truth Social that the US would suspend bombing and other attacks on Iran for two weeks if Tehran agreed to the “full, immediate and safe” reopening of the Strait of Hormuz. He said the decision followed talks with Pakistani Prime Minister Shehbaz Sharif and Field Marshal Asim Munir, and described it as a mutual ceasefire applying to both sides.

Trump said the US had already met and exceeded all of its military objectives. He added that Washington was very close to a final agreement for long-term peace with Iran and, more broadly, peace in the Middle East.

He also said Iran had delivered a 10-point proposal that he viewed as a substantive basis for negotiations. Most past points of dispute had already been resolved, he said, and the next two weeks would be used to finalize a deal.

The ceasefire proposal was reported to have come at Pakistan's suggestion. Sharif said in a post on X that he had asked Trump earlier in the day to extend the negotiation deadline by two weeks to give diplomacy a chance to work. At the same time, he urged Iran to show goodwill by keeping the Strait of Hormuz open during that period.

Under the arrangement, the US would delay for two weeks the large-scale strikes it had been considering on bridges, power plants and other targets inside Iran. Iran, in turn, would ensure safe passage through the Strait of Hormuz, as Washington had demanded, allowing negotiations to continue. Sharif said all parties to the conflict should observe a ceasefire across the region over the next two weeks to give diplomacy a chance to end the war.

Iran also appeared receptive to the proposal. Reuters, citing an unnamed senior Iranian official, reported that the Iranian government was reviewing the plan positively.

The decision gives the US and Iran two additional weeks for talks through Aug. 21.
