China's financial supervision institutions are composed of China People's Bank (PBC), State Administration of Foreign Exchange (SAFE), China Banking Regulatory Commission (CBRC), China Securities Regulatory Commission (CSRC) and China Insurance Regulatory Commission (CIRC). Through these five institutions, a national financial supervision pattern of one line, one bureau and three meetings has been formed. These five institutions play the role of supervision and management through the promulgation and implementation of various policies and regulations. As a financial supervision institution, its most important duty is to supervise the operational risks of financial institutions, so that banks and other financial institutions can provide high-quality and efficient services to enterprises in accordance with regulatory requirements. Financial regulators supervise financial institutions from three aspects: market access, institutional operation and market withdrawal.
