WASHINGTON - It remains "early days yet" for the U.S. Federal Reserve in terms of assessing whether its interest rate increases have gone far enough to bring inflation back to the Fed's 2% target, with the lagged impact of policy yet to be fully felt, Boston Federal Reserve president Susan Collins said on Friday.

It is "early days yet in terms of assessing whether we really have gone as far as we need to go," Collins said in an interview on Bloomberg Television following the release of data showing consumer spending was basically flat in February after a large jump in January.
