Banks’ interconnections and peer effects: Evidence from Chile

Abstract

In this paper, we identify and quantify the importance of endogenous peer effects in the interbank market, allowing for varying degrees of intensity of these peer effects. We base our analysis on a unique dataset that includes all interbank loans that have taken place between 15 banks in the Chilean interbank market representing more than 95% of the market between 2009 and 2016. This approach contrasts sharply with the geographical definition of peers used by most of the literature. As an application of our model, we examine an episode of liquidity shortage experienced by one Chilean bank in the interbank market, with the lenses of our model. We show evidence consistent with a herding behavior of the lender banks which, according to our model, were peers of the stressed bank.

I am a Ph.D. student at Tilburg University. Prior to my enrollment as a Ph.D. student, I worked as a research assistant in the Financial Research Unit of the Central Bank of Chile. At the Central Bank, I did research related to financial networks and systemic risk of financial institutions. My current research lies in the intersection between Macroeconomics, Finance, and Labor Economics. I am particularly interested in understanding the macroeconomic implications of different contractual arrangements on the business cycle.
