Fed goes with half-point interest rate cut. What that means.

This story was updated to add new information.

WASHINGTON — In the end, the Fed decided to go big.

The Federal Reserve lowered its key interest rate by a hefty half percentage point Wednesday, moving ahead with its first rate cut in four years and cheering markets that expected an emphatic move amid a softening jobs picture.

With the slowing labor market posing a growing risk to the economic expansion, Fed officials opted for a bold approach to launch a projected flurry of rate cuts now that inflation is easing.

But the central bank forecast a total of just a half point in additional cuts the rest of the year, signaling officials don’t believe the job market is collapsing.

“The (Fed) has gained greater confidence that inflation is moving sustainably toward 2%, and judges that the risks to achieving its employment and inflation goals are roughly in balance,” the Fed said in a statement after a two-day meeting. “The economic outlook is uncertain, and the Fed is attentive to the risks of both sides of its dual mandate.”

Fed officials also said “inflation has made further progress toward (their) 2% goal.”

Fed Governor Michelle Bowman was the lone dissenter, preferring a quarter-point cut.

At a news conference, Fed Chair Jerome Powell acknowledged that job growth has slowed.

"Clearly, payroll job creation has moved down in the last few months and that bears watching," he said. "The upside risks to inflation have really come down and the downside risks to employment have increased."

But he added the economy and job market are still on solid footing.

"Our intent with our policy move today is to keep it there," he said. "The time to support the labor market is while it's strong, not when you start seeing layoffs... You can take this as a sign of our commitment not to get behind."

In a research note, Ryan Sweet, chief U.S. economist of Oxford Economics, said the Fed likely should have started lowering rates in July and Wednesdays' big cut was an attempt "to get caught up." Powell told reporters officials may have started lowering rates in July if a report on unusually weak job growth that month had been available at the time.

"The September decision is a preemptive strike to increase the odds that the central bank can pull off a soft-landing" in which the Fed's high rates bring down inflation without causing a recession, Sweet said.

What is the current Fed interest rate?

The Fed’s decision lowers its benchmark short-term rate to a range of 4.75% to 5% from a 23-year high of 5.25% to 5.5%. The move is expected to ripple through the economy, providing the first dose of relief in years to Americans who have struggled with high borrowing costs for mortgages, credit cards, and auto and other loans.
