(Yicai Global) Sept. 5 -- The central parity rate of the yuan (CNY) against the US dollar (USD) declined 298 basis points before the opening of interbank market on Tuesday. It marks the seventh consecutive days in the trend of appreciation of the yuan.

The China Foreign Exchange Trade System (CFETS), the interbank trading and foreign exchange division of China's central bank, the People's Bank of China (PBOC), set the yuan central parity rate at 6.5370 against the dollar on Monday, compared with the official close of 6.5200 on Monday. It is the strongest level the yuan reached against the dollar in more than 14 months.

In addition, the onshore and offshore exchange rate of the yuan against the dollar also broke thresholds of 6.52 and 6.53 on Monday, respectively, down 421 points and 403 points compared with the previous trading day. At some stage, they even hit the lowest quotations of 6.5175 and 6.5204. This represents the yuan's strongest performance during the latest round of appreciation.

Apart from its rise against the dollar, the yuan has also appreciated against other major currencies. The central parity rates of the yuan against the euro, 100 yen and the British pound were 7.7610, 5.9442 and 8.4306, respectively, declining 414 points, 325 points and 790 points.

Overnight, the dollar index that tracks the greenback against a basket of other currencies remained low, as Friday's disappointing U.S. employment data continued to weigh on the currency and that North Korea's nuclear tests stirred investors' concerns.
