Local versus aggregate lending channels: the effects of securitization on corporate credit supply

While banks may change their credit supply due to bank balance-sheet shocks (the local lending channel), firms can react by adjusting their sources of financing in equilibrium (the aggregate lending channel). We provide a methodology to identify the aggregate (firm-level) effects of the lending channel and estimate the impact of banks’ ability to securitize realestate assets on credit supply for non real-estate firms in Spain over 2000-2010. We show that firm-level equilibrium dynamics nullify the strong local (bank-level) lending channel of securitization on credit quantity for firms with multiple banking relationships. Credit terms however become softer, but there are no real effects. Securitization implies a credit expansion on the extensive margin towards first-time bank clients, which are more likely to default. Finally, the 2008 securitization collapse reverses the local lending channel.
