The Federal Reserve’s fight against inflation was going almost unbelievably well. Price increases were coming down. Growth was holding up. Consumers continued to spend. The labor market was chugging along.

Policymakers appeared poised to lower interest rates — just a little — at their meeting on Sept. 18. Officials did not need to keep hitting the brakes on growth so much, as the economy settled into a comfortable balance. It seemed like central bankers were about to pull off a rare economic soft landing, cooling inflation without tanking the economy.

But just as that sunny outcome came into view, clouds gathered on the horizon.

The unemployment rate has moved up meaningfully over the past year, and a weak employment report released last week has stoked concern that the job market may be on the brink of a serious cool-down. That’s concerning, because a weakening labor market is usually the first sign that the economy is careening toward a recession.

The Fed could still get the soft landing it has been hoping for — weekly jobless claims fell more than expected in fresh data released on Thursday, a minor but positive development. Given the possibility that everything will turn out fine, central bank officials are not yet ready to panic. During an event on Monday, Mary C. Daly, the president of the Federal Reserve Bank of San Francisco, suggested that officials were closely watching the job market to try to figure out whether it was cooling too much or simply returning to normal after a few roller-coaster years.

“We’re at the point of — is the labor market slowing a lot, or slowing a little?” Ms. Daly said, as she pointed to one-off factors that could have muddled the latest report, like Hurricane Beryl and a recent inflow of new immigrant workers that left more people searching for jobs.

“It’s clear inflation is coming down closer to our target, it’s clear that the labor market is slowing, and it’s to a point where we have to balance those goals,” she said.
