Episode notes
Money Is The Dominant Medium Of Exchange
- Money is best defined as the dominant medium of exchange in an economy rather than a list of properties.
- Cullen Roche argues bank deposits are the thing with the highest "money-ness" today.
Loans Create Deposits, Not Reserves
- Bank deposits are created endogenously when banks make loans; loans create deposits.
- Repayment of loans destroys deposits, so the money supply expands and contracts with lending activity.
Capitalization, Not Reserves, Constrains Banks
- Reserves are not the true constraint on bank lending because healthy banks can get reserves from the central bank.
- The real constraint is bank health and capitalization, not the quantity of reserves.
