The core function of money is to act as a medium of exchange, enabling the purchase and sale of goods and services without the need for a barter system. It serves as a universally accepted intermediary, allowing for efficient trade rather than direct swaps.
Key functions of money include:
- Medium of Exchange: Facilitates trade, allowing people to sell goods for money and use that money to buy other goods.
- Unit of Account (Measure of Value): Provides a standard unit for measuring and comparing the market value of different goods and services, debts, and assets.
- Store of Value: Allows wealth to be saved and stored, maintaining purchasing power for future use.
- Standard of Deferred Payment: Enables borrowing and lending, serving as a reliable mechanism for settling future debt payments.
These functions combined solve the inefficiency of bartering, supporting complex economic transactions and stability.
