On Wednesday, Fed Chairman Ben Bernanke said the central bank was not ready to cut back on stimulus measures, citing tightening financial conditions that could hurt employment.

Daiwa's Chris Scicluna said the Fed's silence on when it might start tapering suggested it might not start scaling back stimulus measures until 2014.

"The FOMC (Federal Open Market Committee) again was content to leave uncertainty persisting over quite when exactly it might start to taper, with (Chairman Ben) Bernanke emphasizing that there is no fixed time-table, and that the Committee's decisions about the pace of purchases will be data-contingent, as well as dependent upon a cost-benefit analysis of the program. So, while still possible, there is far from a done deal that tapering will start by year-end," Scicluna said in a research note.
