TOKYO -- The impact of Japan's upcoming election is spreading into currency markets as overseas investors question what a strong showing by Tokyo Gov. Yuriko Koike's new national party might mean for the loose monetary policy that has kept the yen weak.
The Japanese currency softened beyond 113 to the dollar Wednesday after the release of a framework for a U.S. tax overhaul, but it quickly firmed up to the 112-yen range, where it has hovered since.
