Yuan rate to remain stable, says central bank

China's central bank is capable of keeping the yuan "basically stable at a reasonable equilibrium level", in spite of "speculating forces", according to a report on the bank's website on Thursday.

The reassurance by the People's Bank of China came as the currency's central parity rate lost 332 basis points to 6.5646 against the US dollar on Thursday, the lowest level since March 18, 2011, according to data from the China Foreign Exchange Trading System.

The renminbi's exchange rate is supposed to go along with market forces, which should be the supply and demand of foreign exchanges based on the real economy, instead of speculative forces using excessive leverage, the report said.
