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. Despite appearing financially sound, SVB failed and was taken over by the Federal Deposit Insurance Corporation (FDIC), demonstrating the critical role banks play in the economy and the necessity of regulatory oversight.
Key Point: Banking involves more risks than most other businesses due to the nature of deposits and lending.
Example: SVB's failure was significant due to its size and impact on the financial system.
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 repayment of debts. Assets are anything of value owned by a person or firm.
Key Point: Money serves as a medium of exchange, a unit of account, a store of value, and a standard of deferred payment.
Why Do We Need Money?
Before the invention of money, trade required barter, which necessitated a double coincidence of wants. The introduction of money made trade easier and enabled economic specialization.
Key Point: Commodity money, such as gold or animal skins, was used historically because it had value independent of its use as money.
Example: Societies used shells, precious metals, and other items as commodity money.
Primary Functions of Money
Functions Explained
Medium of Exchange: Money is widely accepted for payment of goods and services.
Unit of Account: Money provides a standard measure of value.
Store of Value: Money allows people to save purchasing power for future use.
Standard of Deferred Payment: Money facilitates transactions over time, with predictable value.
Characteristics of Good Money
Requirements for Acceptable Money
Acceptability: Usable by most people.
Standardized Quality: Uniform units.
Durability: Resistant to wear and tear.
Valuable Relative to Weight: Easy to transport.
Divisibility: Usable for transactions of varying sizes.
Types of Money
Commodity Money
Commodity money has intrinsic value independent of its use as money. Examples include:
Shells in Asia
Gold and silver
Animal pelts and skins in colonial North America
Cigarettes in prisons and prisoner-of-war camps
Fiat Money
Fiat money is authorized by a governmental body and is not backed by a physical commodity. Modern economies use fiat money, such as paper currency issued by central banks.
Key Point: Fiat money's value depends on public confidence; if confidence is lost, the money can become worthless.
Example: The U.S. dollar is fiat money issued by the Federal Reserve.
Transition from Commodity to Fiat Money
Historical Development
Paper money originated in China and spread globally. Initially, it was exchangeable for commodities like gold. Today, central banks issue fiat money not backed by commodities.
Key Point: The flexibility of fiat money allows central banks to manage the money supply more effectively.
Summary Table: Commodity vs. Fiat Money
Type | Definition | Examples |
|---|---|---|
Commodity Money | Has intrinsic value | Gold, silver, shells |
Fiat Money | Value by government decree | U.S. dollar, Euro |
