Essays on the bank lending channel

Abstract

Esta tesis estudia los cambios en la oferta de crédito de los bancos cuando se enfrentan a incertidumbre, supervisión regulatoria y políticas macroprudenciales. El primer capítulo propone un nuevo índice para detectar la incertidumbre idiosincrática de los bancos a nivel trimestral. Para desarrollar la nueva medida, utilizo técnicas de aprendizaje de máquinas y procesamiento del lenguaje natural sobre los discursos trimestrales hechos por la gerencia de cada banco. Encuentro que una mayor incertidumbre está asociada con un menor préstamo el próximo trimestre y una mayor liquidez, lo que sugiere un manejo activo de la incertidumbre. El segundo capítulo explora cómo los bancos responden a la supervisión maquillando sus balances. En preparación para la revisión de calidad de activos (AQR) de 2014 en Europa, los bancos revisados redujeron su participación en bonos y préstamos riesgosos. Después del AQR, los bancos volvieron a adquirir bonos más riesgosos en sus balances, pero no créditos más arriesgados. En el tercer capítulo, estudio cómo la introducción de controles de capital en Colombia afectó el crédito doméstico. Los resultados apuntan a complementariedades entre la oferta de crédito domestico y externo.

This thesis contributes to the understanding of how banks shift their supply of credit when confronted with uncertainty, regulatory supervision and macroprudential policies. The first chapter proposes a new index to detect the idiosyncratic uncertainty banks face at the bank-quarter level. I use machine learning and natural language processing on speeches made by bank management during quarterly earnings conference calls to develop the new measure. I find that higher uncertainty is associated with lower lending the next quarter and higher liquidity, suggesting active management of uncertainty. The second chapter explores how banks respond to supervision by window-dressing their balance sheets. In preparation for Europe’s 2014 Asset Quality Review (AQR), reviewed banks decreased their share of riskier securities and loans. After the AQR, banks reloaded riskier securities onto their balance sheets, but not riskier credit. In the third chapter, I study how the introduction of capital controls in Colombia affected domestic credit. The results point to complementarities in credit supply between domestic and foreign credit.
