We investigate how monetary policy in a mixed financial system such as that of China, which is characterized by a juxtaposition of quantity- and price-based policy instruments and the co-existence of regulated and market-determined interest rates, affects bank lending. Using a newly constructed loan-level dataset, we find that loan rates but not loan size are affected by both the regulated and the
market-determined interest rates and that loan size is instead affected by an implicit quota that is imposed on aggregate bank lending through window guidance. We interpret this finding to be evidence of credit rationing.
