Federal Reserve

Federal Reserve Board Chair Jerome Powell speaks at a news conference Wednesday following a two-day meeting of the Federal Open Market Committee in Washington.

WASHINGTON — A sharply divided Federal Reserve cut its benchmark interest rate Wednesday for a second time this year but declined to signal that further rate cuts are likely this year.

The Fed’s move reduced its key short-term rate — which influences many consumer and business loans — by an additional quarter-point to a range of 1.75% to 2%.

The action was approved 7-3, with two officials preferring to keep rates unchanged and one arguing for a bigger half-point cut. The divisions on the policy committee underscored the challenges for Chairman Jerome Powell in guiding the Fed at a time of high economic uncertainty.

The Fed did leave the door open to additional rate cuts — if, as Powell suggested at a news conference, the economy weakens. For now, he suggested, the economic expansion appears durable in its 11th year, with a still-solid job market and steady consumer spending.

At the same time, the Fed is trying to combat threats including uncertainties caused by the U.S. government’s trade war with China, slower global growth and a slump in American manufacturing.

The Fed noted in its statement that business investment and exports have weakened.

At his news conference, Powell acknowledged that Fed officials are sharply divided about the wisest course for interest rates, especially given uncertainties, like trade conflicts, whose outcomes are out of the Fed’s control.

“This is a time of difficult judgments and disparate perspectives,” the chairman said.

In any case, many business leaders are skeptical that the Fed’s slight rate cuts will deliver much economic benefit.

Wednesday’s rate cut “makes virtually no difference to the U.S. economy in and of itself,” said Jamie Dimon, CEO of JPMorgan Chase, who suggested, as many corporate leaders have, that the trade war remains an overarching threat.

“I don’t think cutting rates will offset trade, personally,” said Dimon, head of the largest U.S. bank.

Among Powell’s challenges is that the trade war’s uncertainties are likely affecting the nation’s economic data, making it hard for the Fed to set an interest-rate policy for the months ahead.
