Powell and other Fed officials in recent weeks have walked a middle ground, flagging risks like continued uncertainty on the global trade front, low inflation and a weakening world economy, but repeating the view the United States is fundamentally in a good spot.
Powell is expected to elaborate on the Fed's thinking in a news conference at 2:30 p.m. EDT (1830 GMT).
The Fed said in its statement that it continued to regard the labor market as "strong" and added that household spending had "picked up." But it noted business spending was "soft" and that measures of inflation compensation remain low.
