💰 Money & Banking

Part 1 of 7 — Functions of Money & the Banking System

🔑 Key Concept: The AP exam tests the three functions of money, the difference between M1 and M2 money supply, and how the money multiplier allows banks to create money through lending.

📖 Functions of Money

Characteristics of Good Money

• Durable — doesn't deteriorate quickly
• Portable — easy to carry
• Divisible — can be broken into smaller units
• Uniform — each unit is identical
• Scarce — limited supply (otherwise value falls)
• Acceptable — widely recognized and trusted

The Money Supply

Key Distinctions

• Money ≠ wealth — money is a medium of exchange; wealth includes all assets
• Money ≠ income — income is a flow (earned over time); money is a stock (held at a point in time)
• Liquidity = how quickly an asset can be converted to cash without loss of value
• M1 is more liquid than M2 (checking > savings > CDs)

🔑 AP Connection: The AP exam will ask you to classify items as M1, M2, or neither. Key trap: credit cards are NOT money — they are a loan (liability), not an asset.

📖 Fractional Reserve Banking & the Money Multiplier

Fractional Reserve System

• Banks are required to hold only a fraction of deposits as reserves
• The rest can be loaned out — and those loans create NEW deposits, which create more loans, etc.
• This process multiplies the initial deposit into a much larger increase in the money supply

Money Multiplier Formula

Money Multiplier = 1 ÷ Required Reserve Ratio (RRR)

Example: RRR = 10% (0.10)

• Money multiplier = 1 ÷ 0.10 = 10
• A $1,000 initial deposit can create up to $10,000 in total money supply
• Maximum change in money supply = Initial deposit × Money multiplier = $1,000 × 10 = $10,000
• Maximum change in LOANS (new money created) = $10,000 − $1,000 (original deposit) = $9,000

Important Caveats

• This is the maximum possible expansion — actual expansion is less if banks hold excess reserves or people hold cash
• If the Fed changes the reserve requirement, the multiplier changes
• Lower RRR → larger multiplier → more money creation from each dollar of reserves

🔑 AP Connection: The money multiplier calculation is tested on EVERY AP exam. Remember: Total change in money supply = initial deposit × multiplier. Total change in LOANS = total change in money supply − initial deposit.
