SINGAPORE—The yen tumbled on Tuesday after the Bank of Japan (BOJ) maintained its ultra-loose monetary policy, as expected, and more surprisingly did not signal a change was approaching, while the dollar drifted at the low end of its recent range.

The dollar and euro both climbed 1 percent on the yen, each set for its biggest daily gain since end October, with the greenback reaching 144.27 yen, and the common currency 157.68.
