Bloomberg reports that China's yuan surged by the most in more than a decade, catching up with dollar declines during a week-long holiday, after the central bank chief voiced support for the currency and set its fixing at a one-month high. The currency advanced 0.89 percent, the most since the nation scrapped a peg to the dollar in July 2005, to 6.5174 a dollar as of 9:46 a.m. in Shanghai, according to data compiled by Bloomberg. The offshore yuan traded in Hong Kong fell 0.18 percent to 6.5201. The People's Bank of China earlier raised the daily fixing against the dollar, which restricts onshore moves to a maximum 2 percent on either side, by 0.3 percent to 6.5118, the strongest since Jan. 4. A gauge of dollar strength declined 0.8 percent last week, when onshore Chinese markets were shut for the Lunar New Year Holiday.
