Wall Street opens higher after Fed signals slow tightening

Wall Street was higher at the open, a day after the Federal Reserve said the U.S. economy is likely strong enough to withstand an interest rate increase later this year but indicated that the pace of a hike will be slower than expected.

The Fed cut its economic growth forecasts for 2015 because of a weak start to the year. Even if a majority of Fed officials continue to see higher rates by the end of 2015, they expect rates to rise slightly less by the end of 2016 and 2017 than they did in their March forecasts.

In a press conference following the end of the Fed's two-day policy meeting on Wednesday, Fed Chair Janet Yellen said she wanted "more decisive evidence" that labor markets were healing, and that wages would increase beyond their current "subdued pace."

Yellen added that the Fed remains data-dependent, which will prompt investors to keep a sharper eye on the data in the coming months, especially on the monthly employment report.

"If we see the kind of jobs data that we saw last month, that would keep the Fed on path to raise rates once in September and may be again in December," said Art Hogan, chief market strategist at Wunderlich Securities in New York.

U.S. consumer prices in May recorded their largest increase in more than two years as gasoline prices surged. The Consumer Price Index rose 0.4 percent last month after gaining 0.1 percent in April.

Other data showed the labor market continued to tighten as first-time applications for unemployment benefits declined last week to a near 15-year low.
