Adapting lending policies in a “negative-for-long” scenario (Updated October 2020)

What is the long-term impact of negative interest rates on bank lending? To answer this question we construct a unique summary measure of negative rate exposure by individual banks based on exclusive survey data, and couple it with the credit register of Spain to identify this impact on the supply of credit to firms. We find that only after a few years of negative rates do affected banks (relative to non-affected banks) decrease their supply and increase their rates, especially when lowly capitalized and lending to risky firms. However, no firms are facing funding constraints, yet.
