This paper studies the transmission of negative monetary-policy rates via the lending behavior of banks. Unlike for positive rates, the transmission of negative rates depends on banks’ funding structure. High-deposit banks take on more risk and lend less than low-deposit banks. Part of the risk taking comes in the form of new syndicated loans to risky firms without such loans previously, and it is limited to poorly-capitalized banks. Safe borrowers switch from high-deposit to low-deposit banks. The new risky borrowers appear financially constrained, and use the new funding to invest. For identification, we rely on a difference-in-differences approach. Banks with different reliance on deposit funding experience a different pass-through of negative policy rates. To isolate borrowers from interest-rate changes, we use lenders located in a different currency zone. A placebo at the time when policy rates fall — but are still positive — shows no effect. The results point to distributional consequences of negative policy rates with potential risks to financial stability.
