The financial stability legal system is an important institutional basis for improving financial governance，ensuring financial security，and promoting the sustainable development of the financial industry. There are two main models for the construction of financial stability legal systems among the world：one is to make a special law for financial stability and thus guide other relevant laws and regulations；the other is sheerly composed of the financial stability relevant content in various separate laws and regulations. In China’s situation，we recommend the first model to alleviate the problem of legal coordination under the separate supervision system，build consensus from all walks of life，and create a good expectation for maintaining financial stability. Along the thought，China should use the Financial Stability Law to guide the top-level mechanism design of financial stability governance，while improving existing financial laws and accelebrating the formulation of laws on financial infrastructure and financial consumer protection.
