Monetary Transmission through Shadow Banks
I find that shadow bank money creation significantly expands during monetary tightening. This "shadow money channel" offsets the reductions in commercial bank deposits and dampens the impact of monetary policy. Using a structural model of bank competition, I show that heterogeneous depositor clientele quantitatively explains the difference in monetary transmission between commercial and shadow banks. Facing more yield-sensitive clientele, shadow banks pass through more rate hikes to depositors, thereby attract more deposits when the Fed raises rates.
