Money
Overview
Money (貨幣, Money) is a socially accepted medium for facilitating the exchange of goods and services. Originating from ancient barter systems, it evolved through metal coins, paper money, and electronic money, performing four basic functions in modern economies: a measure of value, a medium of exchange, a store of value, and a means of payment. Beyond being a mere economic tool, money deeply influences individual lives, social structures, and international relations.

Origin and History of Money
The history of money began with human civilization. Early forms included shells, salt, and livestock used as currency. Around the 7th century BCE, the first metal coins appeared in Lydia. In China, bronze currency was used around the 11th century BCE, and the first paper money, 'Jiaozi,' was issued during the Song Dynasty. In modern times, the gold standard was established, and after the Nixon Shock in 1971, the shift to a floating exchange rate system ushered in the era of fiat money.
Functions of Money
1. Medium of Exchange: Eliminates the inconvenience of barter and reduces transaction costs.
2. Measure of Value: Measures the value of various goods and services in a common unit.
3. Store of Value: Preserves purchasing power for the future, though its value can be eroded by inflation.
4. Means of Payment: Used to settle debts and taxes.
Types of Money
- Commodity Money: Materials with intrinsic value, such as gold, silver, and copper.
- Fiat Money: Currency legally mandated by a government (e.g., South Korean won, US dollar).
- Electronic Money: Money existing in digital form (e.g., bank transfers, card payments).
- Cryptocurrency: Decentralized digital currency based on blockchain technology (e.g., Bitcoin, Ethereum).
Money and Economic Systems
Central banks regulate the money supply to promote price stability and economic growth. Monetary policy tools include adjusting benchmark interest rates, changing reserve requirements, and open market operations. Excessive money supply can lead to inflation, while insufficient supply can cause deflation. In modern economies, most money exists not as banknotes issued by central banks but as deposits created through commercial bank lending (credit creation).
Psychological Aspects of Money
Money goes beyond being a mere economic tool, deeply influencing human psychology and behavior. According to behavioral economics, people have a strong tendency toward loss aversion, feeling losses more acutely than equivalent gains. Attitudes toward money also vary based on childhood experiences, social comparisons, and cultural backgrounds. While some studies suggest that more money increases happiness, others argue that beyond a certain income level (e.g., $75,000 per year in the US), the effect on happiness is minimal.
Money and Social Inequality
Unequal distribution of money leads to social problems. Income inequality deepens gaps in areas such as education, health, and housing. The top 1% of the world's population owns over 45% of global wealth, while the bottom 50% holds less than 1% of total wealth. Such inequality can reduce social mobility and lead to political instability.
Recent Trends
As of 2024-2025, significant changes are occurring in the concept and use of money. First, the spread of digital currencies. Central banks worldwide are pursuing the introduction of CBDCs (Central Bank Digital Currencies), with pilot programs such as China's digital yuan and the European Central Bank's digital euro. Second, the maturation of the cryptocurrency market. The approval of Bitcoin spot ETFs (2024) has expanded institutional investor participation, and stablecoin regulations are tightening. Third, the development of contactless payments and biometric authentication technologies has led to a sharp decline in cash usage. In South Korea, as of 2024, the transition to a cashless society is accelerating, and the burden of digital payment fees on small business owners has emerged as a social issue. Fourth, the combination of artificial intelligence and fintech is expanding personalized financial services, with AI-based investment advice and robo-advisors becoming commonplace. Finally, amid global inflation and high-interest-rate environments, interest in money's store-of-value function has increased, boosting investment demand for real assets like gold.
