Boston Fed President Eric Rosengren told CNBC on Friday he doesn't expect the U.S. economy to need another round of quantitative easing, but cautioned that he couldn't rule out the option.
"I don't expect that we need to," Rosengren said during an exclusive interview on "Squawk Box." "If the economy got weak enough that it was required, we should do it. I certainly hope and I don't expect that will be the case, but I can't rule anything out at this time."
Speculation over how the Fed will respond to volatility on Wall Street and to concerns over European growth has intensified after Wednesday's wild selloff.
On Thursday, St. Louis Fed President James Bullard helped calm markets when he suggested the central bank could pause the wind-down of its easy money policy and wait for more economic data in December. Both Rosengren and Bullard are nonvoting members of the Federal Open Market Committee, the Fed's policy-setting board.
During his CNBC interview, Rosengren added that Fed officials need time to fully process what's causing widespread turmoil in the financial markets before making a judgement on changing the pace of winding down the current round of quantitative easing.
"Financial markets have been quite turbulent," Rosengren said. "I would remind you though that just a couple months ago we were talking about how little turbulence there was. It's going to take us a little time to fully process what exactly is the reason for the turbulence."
