SHANGHAI, Oct 10 (Reuters) - China's central bank lifted its official yuan midpoint to 6.6273 per dollar on Tuesday, its first firmer fixing since Sept. 22, reflecting spot yuan performance a day earlier.
The official guidance was 220 pips or 0.33 percent firmer than the previous fix of 6.6493 on Monday. The move in the midpoint was the biggest strengthening in percentage terms since Sept. 8.
China's yuan inched up against the U.S. dollar on Monday on the first day of trading after a week-long holiday amid thin liquidity and as traders awaited cues on the currency ahead of a key national leadership meeting next week.
