Total banking sector assets rose 19.2% to US$4.89 trillion at the end of March, China Banking Regulatory Commission figures show. The assets of the four largest state-owned commercial banks grew 17.4% year-on-year to US$2.6 trillion at the end of March, while assets belonging to the country's 12 second-tier banks climbed 26.9% to US$757.8 billion. City commercial banks' assets totaled US$261 billion, up 25.3%, while assets at other banking-sector institutions, including policy banks, foreign banks and credit cooperatives, climbed 17.5% to US$1.28 trillion. Despite being out-performed by their smaller rivals, the big-four banks held on to their dominant market position. At the end of March they accounted for 53% of China's total banking assets, down less than one percentage point from a year earlier.
