"An argument can be made for a rise in interest rates at this time," Fed Chair Janet Yellen said at a news conference.But she added, "We want to take more time to evaluate the likely impact on the United States" from the overseas slowdown and market gyrations.

She said Fed policymakers also want to see if further improvement in the labor market "will bolster our confidence that inflation will move back" to the Fed's annual 2% target over the medium term..

In a statement after a two-day meeting, the Fed said, "Recent global economic and financial developments may restrain economic activity somewhat and are likely to put further downward pressure on inflation in the near-term."

Fed policymakers now expect just one rate hike this year that would push the funds rate to 0.375% from the current 0.125%, according to their median forecast. They also expect a slower rise that would leave the rate at 2.625% by the end of 2017 and a longer-run normal rate of 3.5%, down from their previous estimate of 3.75%.

The central bank said "the labor market continued to improve, with solid job gains and declining unemployment." It said consumer spending and business investment have advanced moderately while the housing market "has improved further." But amid the overseas troubles, it said exports have been "soft."

With the U.S. economy rebounding more strongly in the second quarter after a slowdown early in the year, the Fed raised its median forecast for economic growth this year to 2.1% from 1.9% in June. But after the recent global and market troubles, it lowered its projection for 2016 to 2.3% from 2.5% in June.

And with the 5.1% unemployment rate already below the Fed's previous year-end forecast, it now expects the jobless rate to be 4.8% by the end of 2016, below its June forecast of 5.1%.

Yet the central bank also expects a more modest rise in inflation, providing it more leeway to nudge up rates gently. It slightly lowered its inflation forecast to 1.7% in 2016 and 1.9% in 2017, leaving it below its 2% annual target even in two years.

Supporting the case for a Fed move was a 5.1% unemployment rate that's already at the central bank's long-run target, average monthly job gains of 212,000 this year and healthy economic growth of 3.7% at an annual rate in the second quarter. "The economy has been performing well and we expect it to continue to do so," Yellen said.

Waiting too long to act might force the Fed to hoist rates more rapidly when currently meager inflation eventually heats up, a move that could destabilize markets. Yellen said that could be "disruptive to the real economy." "I don't think it's good policy to have to slam on the brakes," she said

Yellen said she continues to expect tepid inflation to pick up as low oil prices and a strong dollar stabilize, but she said it will take "a bit more time" for those effects to dissipate.Some economists say the 5.1% unemployment rate already heralds a coming surge in wages and prices as employers compete for fewer available workers.

But annual pay growth has been stuck near a sluggish 2% pace, possibly reflecting an excess labor supply that includes part-time workers who prefer full-time jobs and discouraged Americans resuming job searches after years on the sidelines. If that's the case, the Fed may want to keep rates low longer to stimulate the economy so more of those workers can find full-time jobs.

Yellen told reporters the unemployment rate likely "understates the degree of slack in the labor market."

Meanwhile, recent news of China's economic slowdown, and the resulting turmoil in global and U.S. stocks, prompted Fed officials to temper expectations for a rate hike this week.

"The outlook abroad appears to have become more uncertain of late and heightened concerns about growth in China and other emerging market economies have led to notable volatility in financial markets," Yellen said.

She added, "We don't want to respond to market turbulence," but the volatility is prompting the Fed to investigate its cause in the global economy.While U.S. exports to China comprise less than 1% of the nation's gross domestic product, Chinese trade with other countries could have stronger ripple effects on the U.S. economy.

Before the release of the Fed's statement to reporters, a coalition of worker advocacy groups called Fed Up gathered outside holding signs such as, "Whose recovery?" and chanting, "Don't raise the interest rates!"

"The Fed should not make a decision to slow down the economy without hearing from the people it will affect," said Ady Barkan, the head of the group.
