TOKYO, June 10 (Reuters) - The dollar fell against most currencies on Wednesday amid some speculation the U.S. Federal Reserve could take steps to curb a recent rise in bond yields in a policy decision later in the day.
The Australian and New Zealand dollars extended their recent rally against the greenback as investors continue to cheer a resumption of economic activity in both countries following the lifting of coronavirus restrictions.
The main focus is a Fed policy meeting later on Wednesday. While no major changes are expected, recent rises in yields have pushed up the dollar due to increasing signs that the U.S. economy is slowly rebounding from the health crisis shock, though a full-fledged recovery is still distant.
Some analysts are playing down the chance the Fed will adopt yield curve control to guide 10-year Treasury yields lower, but uncertainty about the outcome of the Fed meeting could keep the dollar under pressure.
"The Fed can afford to wait and see on yield curve control because the U.S. economy has gotten past the crisis phase and only just entered the healing phase," said Masafumi Yamamoto, chief currency strategist at Mizuho Securities in Tokyo.
"The markets got overly optimistic and are adjusting lower, but this is a good chance to buy the dollar on the dip."

The euro EUR=D3 rose 0.22% to $1.1364. Against the pound, the common currency bought 88.99 pence EURGBP= .
Concerns about progress in trade talks between Britain and the European Union continue to hamper both the euro and the pound.
The EU's chief Brexit negotiator, Michel Barnier, is scheduled to speak later on Wednesday, which may yield details that will help determine whether market sentiment will improve.
