Stocks tumble on fears about faster rate hikes; Dow is down 570

NEW YORK — Stocks sank Tuesday after the head of the Federal Reserve warned it could turn the dial back up on its hikes to interest rates if pressure stays high on inflation. The warning shook markets and raised worries about a possible recession down the line.

The S&P 500 dropped 1.5% for one of its worst days of the year so far. The Dow Jones Industrial Average lost 574 points, or 1.7%, while the Nasdaq composite fell 1.2%.

Inflation and what the Fed is doing about it have been at the center of Wall Street’s sharp swings this year. After seeming to be on a steady decline since last summer, reports on inflation last month came in surprisingly hot. So did a suite of other data on the economy.

That raised fears that inflation is staying stickier than feared and that the Fed will have to raise rates higher than earlier thought. Higher rates can drag down inflation because they slow the economy, but they hurt prices for stocks and other investments. They also raise the risk of a recession later on.

The Fed’s chair, Jerome Powell, on Tuesday confirmed some of those fears and said the recent data mean “the ultimate level of interest rates is likely to be higher than previously anticipated.” He also said in his testimony to a Senate committee that the Fed is ready to increase the pace of its hikes again if needed.

That would be a sharp turnaround after it had just slowed its pace of increases to 0.25 percentage points last month from earlier hikes of 0.50 and 0.75 points.

“If the totality of the data were to indicate that faster tightening is warranted, we would be prepared to increase the pace of rate hikes,” Powell said.
