Under the new formula, the middle price = closing exchange rate+exchange rate change of a basket of currencies+countercyclical adjustment factor, and some setting factors are provided in the formula framework of countercyclical adjustment factor provided by the central bank.

In response to this news, the China Foreign Exchange Trading Center released a reporter's question, saying that China did consider introducing countercyclical factors into the quotation model of the central parity rate of RMB against the US dollar, with the main purpose of moderately hedging the procyclical fluctuation of market sentiment and alleviating the possible "herd effect" in the foreign exchange market.

Hope to adopt!
