The yen only fell to 152.82 against the dollar, and the market is still debating whether the Bank of Japan will take action at its next meeting on December 19 or about a month later. Shusuke Yamada, head of Japan's foreign exchange and interest rate strategy at Bank of America in Tokyo, said that if policymakers put off raising interest rates for a longer time, the situation would be very different.
