The lending channel under optimal choice of monetary policy

Abstract

Building on Cecchetti and Li (2005), we show that the bank lending channel affects monetary policy trade-offs only when interest rates affect marginal costs of production (ie when there is a cost channel of monetary policy) in the New Keynesian monetary policy model. In our calibrated model the resulting impact of the bank lending channel on output-inflation trade-offs is quantitatively small and of ambiguous sign. When bank capital varies counter cyclically and bank loan rates have a relatively large impact on marginal costs, variation of bank loan margins improves monetary policy trade-offs. The new Basel accord, by increasing capital requirements during economic downturns, offsets this beneficial impact. Keywords: bank capital, bank lending, capital buffers, pro-cyclicality, capital regulation, cost channel, credit channel, loan margins, monetary trade-offs JEL classification numbers: E51, E52, G21
