Wall St muted as investors assess inflation data, Mideast developments

By Twesha Dikshit and Utkarsh Hathi

Wall Street's main indexes retreated from record highs on Thursday as escalating tensions between the U.S. and Iran dampened hopes of an imminent peace deal, while investors digested key inflation data.

Tehran targeted a U.S. airbase on Thursday after Washington launched fresh strikes. The move came hours after President Donald Trump rejected a report that he was close to a compromise deal with Iran.

Oil prices jumped nearly 3%, while U.S. Treasury yields edged higher with the continued closure of the Strait of Hormuz adding to inflation worries.

Data showed U.S. inflation increased at its fastest pace in three years in April, driven by higher energy prices amid the Iran war.

"I don't think the data changed the narrative. The number was not as bad as feared. That pushes back a little bit against some expectations for rate hikes," said Angelo Kourkafas, senior global investment strategist at Edward Jones.

"A lot of the focus will still be on the Iran negotiations and the AI trends and these are the two things that (will) drive the narrative for equities."

At 10:01 a.m. ET, the Dow Jones Industrial Average fell 110.97 points, or 0.22%, to 50,533.31, the S&P 500 gained 1.71 points, or 0.02%, to 7,521.68 and the Nasdaq Composite lost 6.80 points, or 0.02%, to 26,667.93.
