The Federal Reserve is still months away from beginning the process of scaling back its $85 billion a month bond-buying program, JPMorgan Chase's chief economist told CNBC on Wednesday, ahead of Fed Chairman Ben Bernanke's economic testimony on Capitol Hill.

"Bernanke is pretty much going to keep the course here and tell us the Fed is open-minded. It's feeling a little better about the economy," Bruce Kasman said in a "Squawk Box" interview. "But he's not going to send any signal about tapering or anything broad on monetary policy at this stage."
