I think it is clear that the relationship between SAFE and the central bank is clear.
Safe is: to study and put forward policy suggestions on the reform of foreign exchange management system, prevention of balance of payments risks and promotion of balance of payments; Study and implement policies and measures to gradually promote the convertibility of RMB capital account, cultivate and develop the foreign exchange market, and provide suggestions and basis for the People's Bank of China to formulate RMB exchange rate policy.
All foreign exchange quotations are published by our central bank, which means that the foreign exchange quotations you see on the websites or counters of major banks are actually the central bank's.
Safe only has the right to suggest.
