The central parity rate of the Chinese currency renminbi (RMB), or the yuan, strengthened 78 basis points to 6.7593 against the US dollar Monday, according to the China Foreign Exchange Trade System.

In China's spot foreign exchange market, the yuan is allowed to rise or fall by two percent from the central parity rate each trading day.

The central parity rate of the yuan against the US dollar is based on a weighted average of prices offered by market makers before the opening of the interbank market each business day.

Recently, the depreciation of the RMB has accelerated, and the fluctuation of the exchange rate will have a direct impact on the performance of some listed companies. 

On July 20, the onshore RMB against the US dollar once fell below the 6.81 threshold, and the offshore RMB against the US dollar also fell below the 6.83 threshold, both hitting a recent low.

Some insiders pointed out that financial situation has become more complicated since end of the second quarter due to increased uncertainties in the market. The foreign exchange market is expected to become more diversified and volatile. Given that the stock price of listed companies is affected by many factors, the correlation between exchange rate changes and the medium and long-term trend of the industry is not significant.
