Loan growth and bank risk: New evidence

This study provides new evidence on the relationship between abnormal loan growth and banks' risk-taking behavior using data from a rich panel of Colombian financial institutions. We show that abnormal credit growth during a prolonged period leads to an increase in banks' riskiness, accompanied by a reduction in solvency and an increase in the ratio of nonperforming loans to total loans. We also show that abnormal credit growth played a fundamental role in the bank-failure process during the late 1990s financial crisis in Colombia. Our results have important implications for financial regulation and macro-prudential policy. © 2013 Swiss Society for Financial Market Research.
