Abstract
We study a liquidity management channel through which sterilized foreign exchange intervention can affect bank lending and the real economy. In the model, the central bank holds foreign reserves and sterilizes its foreign asset purchases by issuing central bank bills that are liquidity management instruments for commercial banks. Sterilized intervention can affect bank lending by altering the supply of liquidity management instruments, which is referred to as the liquidity management channel. We use the model to study the optimal foreign exchange intervention policy in response to portfolio flow shocks and the optimal choice of sterilization instruments. The infinite horizon version of the model is calibrated to the Chinese economy and can explain the observed co-movements of foreign reserves, central bank bills and bank lending.
