June 27 (Bloomberg) -- The dollar declined the most against the euro in a month and dropped versus the yen after China repeated its call for a new global currency.

The Swiss franc declined against the euro and dollar this week as foreign-exchange analysts said the central bank sold its currency three times to support the economy. The greenback fell against most of its major counterparts after the People’s Bank of China said yesterday the International Monetary Fund should manage more of members’ foreign-exchange reserves.

“The dollar’s status as a reserve currency is being questioned,” said Benedikt Germanier, a foreign-exchange strategist in Stamford, Connecticut at UBS AG, the second- largest currency trader. “There are reasons to sell the dollar.”

The U.S. currency fell 0.9 percent to $1.4056 per euro this week from $1.3937 on June 19, the swiftest depreciation since the five days ended May 29. The dollar fell 1.1 percent to 95.18 yen f
