The Bank of Japan announced on the 28th that it will maintain the current ultra-loose monetary policy unchanged, but at the same time implement the yield curve control policy more flexibly. Market participants said that this policy corrected the side effects of the policy, but did not change the easing stance. Bank of Japan Governor Kazuo Ueda said that increasing the flexibility of the yield curve control policy is to continue to maintain the current ultra-loose monetary policy. Stimulated by the Bank of Japan's decision, the Tokyo stock market, foreign exchange market and bond market all experienced significant fluctuations.
