St Louis Fed President James Bullard said on Friday that the Fed could look at raising interest rates before completing its QE taper. 

Additional Comments:

"We should end taper by March."

"Ending taper by March would give us optionality to raise rates if needed."

"We don't want to be too slow to react."

"We want to pull back in a way that's not too disruptive."

"A lot of fed policymakers have said they are comfortable speeding taper."

"There's more agreement we have to change the picture, given inflation."

"We could also look at allowing balance sheet to shrink."
