China's banking supervisor said it uncovered 767.1 billion yuan ($95.2 billion) of irregularities at domestic financial institutions last year, about a third more than in 2004.
The government punished 6,826 people and 1,205 institutions, including banks and asset-management companies, for fraud and other illegal activities, in 2005, the China Banking Regulatory Commission said on its Web site.
The regulator ousted 325 senior executives and thwarted 1,272 fraud attempts involving 1.47 billion yuan last year, according to the statement.
China is expanding efforts to clean up corruption and lending scandals that threaten to derail planned share sales by Industrial & Commercial Bank of China and Bank of China, the nation's two largest lenders. Beijing-based China Construction Bank, the No. 3 institution, in October raised $8 billion in the world's biggest initial public offering in four years.
Several senior bank executives including Liu Jinbao, former chief executive of Bank of China's Hong Kong operations, and Wang Xuebing, who used to head Construction Bank, are among those sentenced to prison on corruption charges in recent years.
