The explosive growth of cross-cutting financial products has rapidly changed the operating pattern of the financial system and has become a significant factor affecting the stability of China’s financial system in recent years. It is urgent to improve the functional regulatory framework and dynamic supervision index system. The selection of statistical index system，data quality control，quantity standard setting，data collection and processing program of financial cross product are the weak links to promote the corresponding functional financial supervision. In this paper，we breifly review the history of the cross-cutting financial product supervision，specifically on the working mechanisms of the US Financial Research Office on data collection，the development of data standards and data analysis of the three core operational responsibilities. Besides of which，the corresponding network of financial stability monitoring index system design and other aspects of research are also covered，which would have policy implication for how to improve China’s financial cross-regulation of financial products and countermeasures thinking.
