Regulatory competition in credit markets with capital standards as signals : conference paper

This paper studies regulatory competition in the banking sector in a model where banks are heterogeneous and taxpayers come up for the losses of failing banks. Capital requirements force the weakest banks to exit the market. This gives rise to a signalling effect of capital standards, as borrowing firms anticipate the higher average quality of banks in a more strictly regulated country. In this model, regulatory competition in capital standards may lead to a `race to the top' for two different reasons. First, if the signalling effect is sufficiently strong, the overall demand for loans from the high-quality banks of the regulating country rises, even though the number of active banks in this country is reduced. Second, if governments are heavily concerned about the tax revenue losses arising from bank failures, strict capital requirements are imposed to improve the pool quality of the domestic banking sector and reduce the risk to taxpayers.
