Monetary Policy, Credit Risk, and Profitability: The Influence of Relationship Lending on Cooperative Banks' Performance

Financial theory indicates that low interest rates hamper credit risk and profitability, two interrelated components of banks' balance sheets. Using a simultaneous equations framework, we investigate the effects of euro area monetary easing on cooperative banks' performance depending on their commitment to relationship lending. First, we find no evidence of a risk-taking channel of monetary policy for consolidated cooperative banks. Further, the profitability of relationship-based cooperative banks is more severely hit in a low interest rate environment than that of consolidated cooperative banks. This raises issues about the middle-term durability of relationship lending when rates hold "low-for-long". Finally, non-cooperative banks and relationship-based cooperative banks both increase credit risk under accommodating monetary policy. However, we suggest that these similarities do not occur for the same reasons: while non-cooperative banks prioritize profitability through higher credit risk when interest rates fall, relationship-based cooperative banks instead increase their capital buffers to ensure credit access to their customers, which mainly comprise small businesses and high-risk firms.
