11:53 AM EDT, 04/10/2026 (MT Newswires) -- US equity indexes were mixed in midday trading Friday as a fragile Iran ceasefire deal looked set to hold until peace talks kick off in Pakistan, while a red-hot inflation read was in line with market expectations.

The Nasdaq Composite rose 0.4% to 22,913.3, while the S&P 500 was slightly down at 6,823.6 and the Dow Jones Industrial Average slipped 0.4% to 47,979.1.

Vice President JD Vance, setting off for US-Iran talks in Pakistan's capital Islamabad, said Washington is "willing to extend the open hand" in this weekend's negotiations but warned Tehran not to "try to play us," The Wall Street Journal said.

A key aim of the talks is to fully reopen the Strait of Hormuz, where President Donald Trump said Thursday that Iran is "doing a very poor job" of letting oil flow through and cautioned the country against collecting tolls from ships traveling through the strategic waterway, the report said.

West Texas Intermediate crude oil futures advanced 0.9% to $98.82. Brent crude futures were little changed at $95.67.

In economic news, the US consumer price index accelerated to its highest monthly reading in nearly four years, rising 0.9% in March but in line with expectations, as the Middle East conflict sent energy prices sharply higher. Energy prices jumped about 11% sequentially in March, led by a 21% surge in gasoline, accounting for nearly three-quarters of the headline increase, the Bureau of Labor Statistics data showed.
