In response to the “too big to fail” problem exposed in the 2008 financial crisis，the Financial Stability Board has launched a list of Global Systemically Important Banks（G-SIBs）since 2011，and has proposed more cautious regulatory requirements. From the published list of 9 issues，the G-SIBs membership pattern has undergone significant changes. The number of G-SIBs in Europe has been declining，while the number of banks from China and Canada has been increasing. In order to reduce the cost of supervision，most G-SIBs have adopted de-interbank and de-complexity development strategies，while highlighting the use of financial infrastructure functions，such as custody and clearing. The overall score of G-SIBs system has declined. In sharp contrast to the overall trend，the scores of the Chinese G-SIBs system have continued to rise rapidly in recent years，and the resulting regulatory costs deserve high attention. Due to the increase of their systematically importance，the regulatory pressure on Chinese G-SIBs to meet the requirements for total loss-absorbing capacity is greater. It is recommended that Chinese G-SIBs objectively assess the cost of supervision incorporated into G-SIBs and take effective measures to achieve a balance between business development and regulatory costs.
