Reserve Components: Pre−Crises
FED DepositsVault CashRequired Clearing BalancesExcess Reserves
Figure 17: How banks manage reserves in normal times. Since the mid-1990s, applied vaultcash has increased due to the advent of ATMs. Required clearing balances to cover clearingof interstate checks and other FED functions provided for a fee has also increased. Excessreserves averaged less than $1 billion. Most of the post-crises increase in excess reserves isheld as deposits at the FED.

Consumption and Income Velocity
consumption velocityincome velocity
High interest rates
Low rates
Figure 18: Consumption and income velocity are roughly proportional, indicating govern-ment and firms respond in similar ways to consumers with respect to the effect of interestrates on money holdings. Velocity tends to increase with interest rates. Velocity has alsobeen trending upward over time, probably due to technological advances that allow con-sumers easy access to savings.
