Federal Reserve officials, meeting for the last time under Chair Janet Yellen, left borrowing costs unchanged while adding emphasis to their plan for more hikes, setting the stage for an increase in March under her successor Jerome Powell.

“The committee expects that economic conditions will evolve in a manner that will warrant further gradual increases in the federal funds rate,” the policy-setting Federal Open Market Committee (FOMC) said in a statement Wednesday in Washington, adding the word “further” twice to previous language.

The changes to the statement, collectively acknowledging stronger growth and more confidence that inflation will rise to the 2 percent target, may spur speculation that the Fed will pick up the pace of interest-rate increases. Officials also said inflation “is expected to move up this year and to stabilize” around the goal, in phrasing that marked an upgrade from December.
