Financial investors' lack of faith in another rise in U.S. interest rates this year kept the dollar pinned back on Monday at the start of a week packed with speeches from Federal Reserve and other senior central bank officials.
A small dip for the yen early in European trade was driven by mildly improved appetite for risk among investors and helped keep the dollar index roughly flat on the day as Britain's pound inched higher.
Sterling has recovered from lows hit in the past 10 days due to uncertainty over the makeup of the next government, helped by a shift by several Bank of England policymakers towards raising interest rates this year. It is up 0.01 percent at 1.2717 per dollar.
But markets so far are loathe to buy the Fed's own line that it will raise U.S. rates once more before the end of 2017 and another three times next year.
That has kept Treasury yields at historically low levels and halted any progress for the greenback.
