The US dollar came off its highs in afternoon Asian trade on mild profit-taking but with the currency still above the 114 yen per usd level amid expectations that the US Federal Reserve will further raise key US interest rates when it meets later this month, dealers said. The market is keenly awaiting the release of US May consumer price data and speeches by Fed chairman Ben Bernanke and other Fed officials this week for further clues on rates. "The tone of financial markets and the details of the US data releases this week could either re-shape or tighten expectations of another 25 basis points increase (in US interest rates) at the end of this month," United Overseas Bank said in a note to clients. "The ongoing Fed speeches this week, could also provide additional clues as to whether there is a diversity of views among policymakers on the growth and inflation prospects," it added. Bernanke jolted financial markets last week when he said that while rising energy costs have helped slow the pace of economic growth, core inflation -- excluding energy and food -- was near the central bank's tolerance level and could warrant further rate tightening.
