Staff Working Paper No. 907
By Yvan Becard and David Gauthier
Credit spreads on household and business loans move in lockstep and spike in every recession. We propose a theory as to why banks tighten their lending standards following a drop in market sentiment. The key feature is a procyclical shadow banking sector that shifts risk from traditional banks to investors through securitisation. We fit the model to euro‑area data and find that market sentiment shocks are the main driver of business and financial cycles over the past two decades.
