This paper identifies a monetary policy channel through the risk pricing of bank debt in the market for jumbo certificates of deposit (jumbo CDs). Adverse policy shocks increase debt holder perceptions of bank default, increasing the risk premia for some banks, thereby decreasing their external funding of loans. The results show that contractionary policy increases the sensitivity of jumbo-CD spreads to leverage and asset risk for small banks, and to leverage for large banks. The results also show a distributional and aggregate effect on banking system jumbo CDs and total loans, producing a risk-pricing (or market discipline) channel. This channel has implications for monetary and regulatory policies, and financial stability.
