The Fed kept interest rates unchanged, as was largely expected. The central bank's policymaking committee also noted that "overall inflation and inflation for items other than food and energy have moved close to 2 percent." That was an upgrade from the March meeting in which the FOMC said the indicators "have continued to run below 2 percent."
The change is key as Fed officials consider 2 percent to be a healthy level of inflation and a key for continuing to push rates higher.
Michael Shaoul, chairman and CEO of Marketfield Asset Management, also pointed out the central bank used the word "symmetric" to describe its inflation target. "We imagine that its use indicates a willingness to allow inflation to track higher than 2 percent for a period to compensate for the long time that it stayed below this level," he said.
