Money, Banking, and the Financial System: Principles of Macroeconomics Study Notes

Money and the Fragility of Banking

Case Study: Silicon Valley Bank Collapse

The collapse of Silicon Valley Bank (SVB) in March 2023 highlights the risks inherent in banking and the importance of government supervision. SVB, despite having over $200 billion in assets and significant deposits, failed and was taken over by the Federal Deposit Insurance Corporation (FDIC). This event underscores the critical role banks play in the economy and the necessity of regulatory oversight.

• Banking Risks: Banks face more risks than most businesses due to their role in the financial system.

• Government Supervision: Supervision is crucial to maintain stability and prevent systemic crises.

The Nature and Role of Money

Definition of Money

Economists define money as any asset that people are generally willing to accept in exchange for goods and services or for the repayment of debts.

• Asset: Anything of value owned by a person or firm.

Why Do We Need Money?

Before money, trade relied on barter, which required a double coincidence of wants—both parties had to want what the other offered. The invention of money made trade easier and enabled economic specialization.

• Barter: Direct exchange of goods/services.

• Double coincidence of wants: Both parties must want what the other has.

• Commodity money: Goods with intrinsic value (e.g., gold, animal skins).

Primary Functions of Money

Functions

Money serves several key functions in the economy:

• Medium of exchange: Widely accepted for payment of goods and services.

• Unit of account: Standard measure of value.

• Store of value: Allows deferred consumption; retains value over time.

• Standard of deferred payment: Facilitates future payments with predictable value.

Characteristics of Good Money

Requirements for Acceptable Money

For a good to serve as money, it should possess the following characteristics:

• Acceptability: Usable by most people.

• Standardized quality: Uniform units.

• Durability: Resistant to wear and tear.

• Value relative to weight: Easy to transport.

• Divisibility: Usable for transactions of varying sizes.

Types of Money

Commodity Money

Commodity money has value independent of its use as money. Examples include:

• Shells in Asia

• Precious metals (gold, silver)

• Animal pelts and skins in colonial North America

• Cigarettes in prisons and POW camps

Fiat Money

Fiat money is authorized by a government and has no intrinsic value or commodity backing. Modern economies use fiat money, typically issued by a central bank (e.g., the Federal Reserve in the U.S.).

• Advantages: Flexibility in money creation.

• Disadvantages: Relies on public confidence; can lose value if trust erodes.
