Monetary policy, funding cost and banks’ risk-taking: evidence from the USA

How much deposits and equity a bank has influences how a banks’ lending responds to monetary policy. While the responsiveness for the bank lending channel has been well established, this is not the case for the risk-taking channel (RTC). We show in a value-at-risk RTC model that the lending for banks with relatively more equity and non-interest-bearing deposits should respond less to monetary policy tightening. This suggests that non-interest-bearing deposits act as “pseudo capital.” In a panel of US banks, we find strong evidence in support of our model for various risk measures.
