"Ongoing increases in the target range will be appropriate," the U.S. central bank said at the end of its latest two-day policy meeting.
The language acknowledges the broad debate that has emerged around the Fed's policy tightening, its impact on the U.S. and world economies, and the danger that continued large rate hikes could stress the financial system or trigger a recession.
The policy decision set the target federal funds rate in a range between 3.75% and 4.00%, the highest since early 2008.
The U.S. central bank has raised rates at its last six meetings beginning in March, marking the fastest round of rate increases since former Fed Chair Paul Volcker's fight to control inflation in the 1970s and 1980s.
The economy, the Fed noted, appeared to be growing modestly, with still "robust" job gains and low unemployment.
