NEW YORK (Reuters) -- The yen fell in a choppy session on Wednesday, ceding some of the ground gained the previous day when a surprise policy tweak by the Bank of Japan lifted the Japanese currency by 4% against the dollar.
The BOJ decided to change its "yield curve control" policy on Tuesday even as it kept broad policy settings unchanged. It is letting 10-year yields move 50 basis points either side of its 0% target, wider than the previous 25-basis-point band.
