President Donald Trump on Thursday said that he was extending a pause in attacking Iran‘s energy facilities by 10 days, to April 6, at the request of the government of the Islamic Republic.

Trump’s move avoids escalating the war with Iran at a time the United States has signaled it wants a negotiated end to the conflict, and as the key Strait of Hormuz remains almost completely closed to shipments of oil. His announcement came as key U.S. stock market indices fell and oil prices rose.

“As per Iranian Government request, please let this statement serve to represent that I am pausing the period of Energy Plant destruction,” Trump said in a Truth Social post.

“Talks are ongoing and, despite erroneous statements to the contrary by the Fake News Media, and others, they are going very well. Thank you for your attention to this matter!”

The original five-day pause on U.S. attacks on Iran’s power plants and energy infrastructure was due to end Friday. Trump had announced the first pause on Monday on Truth Social.

The war against Iran began on Feb. 28 with strikes by the United States and Israel.

The war has led to sharp increases in the price of oil, as Iran as effectively shut down shipping traffic on the Strait of Hormuz, the world’s most critical passage for the movement of crude.

The benchmark S&P 500 stock market index fell by 1.74% on Thursday, its biggest daily drop since the beginning of 2026, as oil prices rose. Brent crude oil futures rose by more than 5.6%, ending at at $108.01 per barrel.

Trump earlier Thursday told reporters at the White House that the U.S. has “very substantial talks going on with respect to Iran.”

Tehran has denied that it is in direct talks with the U.S.
