Equities on Wall Street fell for a second straight session on Tuesday amid doubts over a fresh round of negotiations between the US and Tehran.

The three main US stock indexes lost 0.6% each, with the S&P 500 closing at 7,064. The Nasdaq Composite ended at 24,260, while the Dow Jones Industrial Average settled at 49,149.4. Barring energy, all sectors were in the red, led by real estate.

Shortly after market close, US President Donald Trump announced the extension of a two-week ceasefire deal with Iran, though he said the naval blockade of Iranian ports will continue. The truce was announced on April 7.

Pakistan Prime Minister Shehbaz Sharif and Field Marshal Asim Munir asked for an extension, Trump said in a Truth Social post.

The blockade of the crucial Strait of Hormuz had fueled uncertainty around a second round of discussions between Washington and Iran, likely to be held in Pakistan, CNN reported Tuesday. US Vice President JD Vance's plans to depart for Islamabad had reportedly been put on hold amid Iran's reluctance to participate in peace talks.

Meanwhile, Kevin Warsh said the Federal Reserve, under his leadership, would be independent from the White House, CNBC reported. He made the remarks at his Senate Banking Committee confirmation hearing. Warsh is Trump's Fed chair nominee.

In economic news, US retail sales last month logged the largest rise since March 2025 amid a surge in spending at gasoline stations as the Middle East conflict boosted energy prices, official data showed.

"We expected that the headline (figure) would be gaudy due to the increase in gas prices and a pickup in unit auto sales, but the strength in other categories was surprising," Jefferies said in a note. "There is no evidence here that higher gasoline prices have motivated the consumer to tighten the belt elsewhere just yet."

US pending home sales increased more than expected in March despite higher mortgage rates, data from the National Association of Realtors showed.
