The yuan jumped the most in eight weeks as the central bank strengthened its reference rate to the limit, helping fend off criticism of China’s currency policy in the run-up to next week’s Group of 20 meeting.

The People’s Bank of China raised the daily fixing by 0.16 percent, the most since May 2, to 6.3089 per dollar today. That was 0.97 percent stronger than yesterday’s closing level in Shanghai and the currency is allowed to trade no more than 1 percent on either side of the fixing. Global leaders, including Chinese President Hu Jintao, will meet in Mexico June 18-19 for the G-20 meeting. China widened the yuan’s daily trading band to 1 percent from 0.5 percent on April 16.

“The fixing is China’s pre-emptive move to ease any pressure on appreciation at the G-20 meetings,” said Stella Lee, president of Success Futures & Foreign Exchange Ltd. in Hong Kong. “The wider yuan trading band has given more room for China to do so before major summits with trading partners. Investors are also betting global central banks will work together to bolster growth.’

The yuan rose 0.08 percent today, the most since April 17, to close at 6.3651 per dollar in Shanghai, according to the China Foreign Exchange Trade System. It also gained 0.08 percent since June 8, the first weekly advance since May 6. One-month volatility, a measure of exchange-rate swings used to price options, was unchanged at 2.2 percent.
