The regulatory agency responsible for prudential supervision of the banks in China, the China Banking Regulatory Commission (CBRC), is not an independent authority. The agency’s regulatory actions are constrained by the central government, which has to balance the prudential and non-prudential consequences of bank regulation for its political survival. The conditions and limits of the government’s influence on the CBRC is analysed through an investigation of three regulatory cases. The conclusion is that the CBRC’s regulatory actions are determined by the relative importance of prudential outcomes for the government’s policy objectives.
