Charu Chanana, Chief Investment Strategist of Shengbao Bank, stated that the Bank of Japan's policies are insufficient to force a significant appreciation of the yen, and the US dollar is in a fragile state against the yen around 160. The Bank of Japan's interest rate hike cannot compensate for the yield gap between the United States and Japan, and the 7-1 vote weakened market signals. If the US dollar remains above 160 against the Japanese yen, intervention risks still exist.
