The yuan ended at 7.9866 to the dollar on the exchange-traded market, its strongest post-revaluation close, traders said. The yuan traded between 7.9860-7.9935 against the dollar today, according to a Shanghai-based trader at a domestic bank. The 7.9860 level was also the strongest for the yuan since it was revalued by 2.1 pct in July 2005. The central bank set a central parity rate of 7.9936 to the dollar before the start of trading today, against 7.9960 yesterday. The People's Bank of China (PBoC) allows a trading band of 0.3 pct on either side of that level. On Jan 4, China launched an over-the-counter system for the interbank foreign exchange market, allowing market participants to make currency trades on credit without the intervention of a third party. Previously it relied exclusively on an automatic price-matching system, overseen by a centralized government trading center known as the exchange-traded market. The last trading price of 7.9866 is derived from trades only on the exchange-traded market.
