(Yicai Global) July 3 -- The People's Bank of China fixed the yuan's central parity rate against the US dollar 127 basis points weaker to 6.8640 this morning, the biggest change since May 20.

The central parity rate is 195 points weaker than yesterday's closing price.

The central bank's China Foreign Exchange Trade System fixes the benchmark rate each business day and spot rates may deviate 2 percent around that figure.
