The U.S. dollar appreciated against its major counterparts in the Asian session on Monday, as investors await U.S. inflation data and Fed Chair Jerome Powell's semi-annual Congressional testimony for more clues on the timeline for tapering asset purchases by the U.S. Federal Reserve.

Powell's testimony on Wednesday will help gauge whether the Fed will move too soon with tapering its QE program.

Besides CPI data, U.S. retail sales, PPI, jobless claims and industrial production are due this week.

Central bank meetings in New Zealand, Canada and Japan are also in focus.

The greenback approached a 4-day high of 110.28 against the yen, after a drop to 110.01 at 9:15 pm ET. On the upside, 112.00 is possibly seen as its next resistance level.
