What Is It?
Banks create money through lending—when a bank makes a loan, it creates a new deposit (money) that didn't exist before. This fractional reserve banking system expands and contracts the money supply based on lending activity.
Origin
Bank money creation dates to medieval goldsmiths issuing notes against reserves. Fractional reserve banking formalized over centuries. Central banks now regulate reserve requirements and manage monetary aggregates.
Why It Matters
Bank lending drives economic expansion and contraction. Credit creation affects inflation, asset prices, and business cycles. Understanding money creation demystifies monetary policy and explains how economies grow.
Intermediate Level
Market Mechanics
Process: Bank makes loan → creates deposit → borrower spends → funds become deposits elsewhere. Reserve requirements constrain but don't limit creation (banks can borrow reserves). Capital requirements bind more than reserves. Money multiplier theory describes potential expansion.
How It Behaves
Lending expands in booms, contracts in busts—amplifying cycles. Credit growth correlates with asset prices. QE increases reserves but doesn't force lending. Bank health determines lending capacity. Shadow banks also create credit-like instruments.

Institutional Behavior
Central banks manage reserves and liquidity. Regulators set capital requirements (Basel). Banks optimize balance sheets for ROE. Shadow banking creates credit outside traditional system. MMT argues banks don't face funding constraints.

Key Takeaways
Banks create money through lending, making them central to economic expansion. Understanding the mechanics, constraints, and cyclicality of credit creation is essential for macro analysis and financial system understanding.
