The U.S. Federal Reserve's long-stalled "liftoff" of interest rates may finally get airborne this year as policymakers from Chair Janet Yellen on Friday to regional leaders across the United States signaled that the era of easy money is drawing to a close.

Yellen capped off a seemingly coordinated push from the central bank on Friday when she cemented the view that the Fed will raise interest rates at its next meeting on March 14 and 15, and likely be able to move faster after that than it has in years.

It was a welcome turn for the Fed chair, who has hoped to get rates off the ground throughout her three-year tenure, and now sees the economy on track and investors aligned around the idea.
