How to define the responsibilities of the central bank? Will the spillover effects of the Fed policy continue? The "Super Central bank week" just passed, the pace of interest rate hikes in various countries gradually slowed down, including the Federal Reserve, the European Central Bank, the Bank of England, the Swiss National Bank and other central banks announced a pause in interest rate hikes, or signaled the peak of interest rate hikes, and the global monetary policy "roller coaster" entered a new stage. China's central bank cut reserve requirements by 25 basis points for the second time this year. However, the aggressive monetary policies of major countries represented by the United States, while anchoring macro objectives, have to some extent interfered with financial stability. In this context, the discussion on the central bank's responsibility positioning and target selection has increased.
