The upshot of the central bank's decision to leave the federal funds rate unchanged sent a clear signal to investors about its "dovish" disposition.
"We’re definitely hearing a decidedly more dovish Fed and while you could point the finger at pressure from the White House, it’s key to remember that the Fed’s focus has always been on two things and two things only: Jobs and inflation," Mike Loewengart, vice president with E*TRADE Financial Corporation.
"Jobs is strong so no worries on that front, but inflation has been consistently below the Fed’s target, which would suggest they need to act to get it back to where it needs to be. And amid softening economic data, all other influences could be considered noise until the Fed feels the economy is in the right place, with inflation as their guide."
The yield on the 10-year Treasury slipped to 2.03 percent.
