The yen rose from near its weakest level against the dollar since June 2010 after the Bank of Japan (8301) said it will conduct open-ended asset purchases from 2014, disappointing investors who expected bolder action now.

Japan’s currency advanced at least 0.2 percent against all of its 16 major counterparts after the BOJ said it will buy about 13 trillion yen ($146.6 billion) in assets per month from January 2014 and as it set a 2 percent inflation target. The euro rose for the first time in three days versus the dollar after German investor confidence in January increased to the highest in 2 1/2 years, adding to signs that Europe’s largest economy is gathering momentum.
