The CFETS, authorized by the PBC, calculates and publishes the central parity of RMB against USD and other major foreign currencies on each business day.

The central parity of RMB against USD is determined in the following way: The CFETS first enquires prices from all market makers before the opening of the market on each business day. Market  makers should refer to the closing rate of the inter-bank foreign exchange market on the previous day, in conjunction with demand and supply condition in the foreign exchange market and exchange rate movement of the major currencies. CFETS excludes the highest and lowest offers, and then calculates the weighted average of the remaining prices in the sample as the central parity of RMB against USD for the day. The weights are determined by the CFETS in line with the transaction volumes of the respective market makers in the market as well as other indicators such as the performance of market-making.
