US benchmark equity indexes fell intraday and oil prices extended their rally amid growing uncertainty around the reopening of the Strait of Hormuz.

The Nasdaq Composite was down 0.6% at 26,436.2 after midday Tuesday, while the S&P 500 lost 0.3% to 7,727.5. The Dow Jones Industrial Average slipped 0.2% to 53,871.7. Among sectors, communication services saw the steepest decline, while energy paced the gainers.

Secretary of Iran's Supreme National Security Council Mohsen Rezaei said Tuesday that the Strait of Hormuz will remain closed as long as the US does not accept Tehran's conditions, Reuters reported.

Previously, Pakistan's Defense Minister Khawaja Asif told Bloomberg that the US and Iran were close to "some sort of an arrangement."

Iran has reportedly laid out new terms for reopening the Strait of Hormuz, including a permanent end to the war against Tehran and its allies, as well as demanding full compensation for war damages. In response, US President Donald Trump on Monday demanded compensation for those he claimed were killed and wounded by Iran's attacks.

Trump recently indicated to the media that he's prepared to exert greater economic pressure on Iran instead of launching another military attack.

"Uncertainty over a US-Iran deal to end the war and reopen the Strait of Hormuz has grown after Trump demanded compensation for victims of Iranian-backed conflicts, responding to Tehran's reparations demands," Saxo Bank said Tuesday in a report. "The tougher stance lowers chances of a near-term agreement and keeps markets wary, as Iran ties any Hormuz deal with Oman to a broader accord with the US and Trump opts for economic pressure over new strikes."
