Major U.S. stock indexes' losses steepened after the Federal Reserve said it would cut interest rates for the first time in a decade, as hopes for further rate cuts were dampened.
Some investors are betting on more than one rate cut this year, and while the Fed's policy statement left open the door for the central bank to cut rates again, Federal Reserve Chairman Jerome Powell suggested this cut wasn't the beginning of a long easing cycle. He also reiterated the Fed would continue monitoring incoming economic data. Those statements could pare investors' outlook on further rate cuts.
The S&P 500 fell 1.1% in recent trading as Mr. Powell spoke. The Nasdaq Composite dropped 1.2%. The Dow Jones Industrial Average lost more than 300 points, or 1.2%.
Major stock indexes have rallied this year, fueled by the prospect of the first rate cut. The end of the meeting marks a pivotal moment for stocks, bonds and currency markets because of potential clues about what comes next, especially with interest rates already historically low. This cut marks just the fifth time in the past 25 years that the Fed moved to trimming rates from increasing them.
The Fed's policy statement showed that the global economy cast a shadow over the central bank's outlook. Mr. Powell also cited trade tensions as having a significant effect on the economy in his press conference.
"We're entering a period of slower economic growth," said Ben Kirby, a portfolio manager at Thornburg Investment Management.
Much was at stake ahead of the meeting, analysts said. High expectations ahead of the decision meant that the Fed's outlook and wording on further rate cuts could threaten the recent stock rally. Stocks sold off after the policy statement was released, and losses deepened after Mr. Powell said that the central bank's cut was a "mid-cycle adjustment to policy."
The prospect of an interest-rate cut this year also confounded some investors, who point to major U.S. stock indexes near records and unemployment that's near a half-century low. Many companies that have reported earnings have beat analysts' expectations, helping propel stocks to fresh highs last week.
"Why exactly are we cutting rates?" said Eddie Perkin, chief equity investment officer at Eaton Vance Management. "It doesn't really make sense to me." Mr. Perkin said that unresolved trade tensions appear to be a bigger headwind for financial markets than the level of interest rates at the moment.
