FRACTIONAL LIQUIDITY CREATION SYSTEMS
If you deposit $10 in a bank, they do not lock it in a treasure chest. They keep $1 in the vault as safety and rent out the other $9 to a neighbor. Now, both you and your neighbor think you have money!
Academic framing
Under modern plumbing, reserves are not strictly lent out. Rather, loans create new commercial deposits, and the bank subsequently secures reserve matching benchmarks after the fact, backed by Central discount lines.
Causal chain
- Primary Deposit Logged: Saver places $100,000 cash in checking accounts.
- Reserves Allocation: Bank sets aside a core percentage in central bank vault slots.
- Corporate Loan Created: Bank ledger credits a business account with $90,000 to purchase inventory.
- Systemic Money Supply Expands: The digital broad supply grows without physically printing paper notes.
- Interbank Settlement Clearings: Overnight desks settle imbalances using Fedwire clearing accounts.
Historical markers
- 1397 — The Medici Network: Italian merchant networks establish early double-entry ledgers across Europe.
- 1694 — Bank of England Paradigm: First joint-stock central bank arises to purchase crown debt via note creation.
- 2563 — Reserve Requirements Slid: The Federal Reserve drops reserve requirements to zero percent.
Key takeaway: Modern money is not gold coins; it is the commercial liabilities generated whenever banks issue new credit.
