Japan's sticking with the U.S. dollar, for now

Japan's new finance minister, Yasutake Tango, told financial newspapers that Japan will keep buying U.S. Treasuries and supporting the dollar's status, according to reports in both The Wall Street Journal and Bloomberg.

The tune could change though if Masaharu Nakagawa, the shadow finance minister in the Democratic Party of Japan (DPJ), wins in the August elections. The Democratic Party leads in the polls.
