What Is It?
Money is a medium of exchange, unit of account, and store of value. It enables trade without barter, measures economic value, and preserves purchasing power over time. Modern money exists as currency, bank deposits, and digital forms.
Origin
Money evolved from commodity forms (salt, cattle, shells) to metal coins (Lydia, 7th century BCE), then paper money (China, 11th century), and now digital banking. Fiat money (government decree) replaced commodity backing in the 20th century.
Why It Matters
Money is essential for economic activity—trade, saving, investment. Its purchasing power affects all financial decisions. Understanding money creation, inflation, and monetary policy is foundational to finance and economics.
