BOJ and Fed double up on yen, sending it to a five-month low

TOKYO -- The Japanese yen weakened on Thursday after the Bank of Japan said at the end of a two-day policy meeting that it would hold interest rates steady at 0.25%.

The currency fell to over 155 to the dollar after the initial announcement, its weakest point since Nov. 21, from as low as 154.86 earlier in the morning in Tokyo.
