Money: Functions and Forms:
→ Definition → Anything that is generally accepted as a means of payment for goods, services, and repayment of debts
Functions of Money:
→ Medium of Exchange → Enables trade without requiring a double coincidence of wants inherent in barter systems
→ Unit of Account → Provides a common measure to express and compare the value of different goods and services
→ Store of Value → Allows individuals to save income and maintain purchasing power over time for future use
→ Standard for Deferred Payments → Allows individuals to buy goods now and pay for them in the future through credit
Forms of Money:
→ Cash → Banknotes and coins circulating as physical legal tender
→ Bank Deposits → Digital balances held in commercial bank accounts transferred via debit cards or electronic transfers
Example:
→ Expressing a shirt’s price as $20 demonstrates money acting as a unit of account, eliminating the need to price it in terms of apples or shoes
Analysis:
→ Efficiency Gains → Money removes transaction inefficiencies caused by barter, reducing search costs and accelerating market trade
Evaluation:
→ Money acts as an effective store of value only under low inflation; high inflation erodes its purchasing power rapidly
Characteristics of Effective Money:
→ Essential Qualities → Physical and functional traits required for an item to serve successfully as money
→ Acceptability → Must be universally recognized and accepted by buyers and sellers within an economy
→ Durability → Must withstand continuous physical handling and wear without easily disintegrating
→ Portability → Convenient to carry around for daily commercial transactions
→ Divisibility → Capable of being divided into smaller units to facilitate payments of varying amounts
→ Scarcity → Available in limited quantities to preserve its purchasing power and prevent hyperinflation
→ Uniformity / Homogeneity → Units of the same denomination must be identical in appearance and purchasing value
Example:
→ Paper notes and metal alloys are durable and lightweight, unlike perishable agricultural items like cattle or grain historically used as money
Analysis:
→ Loss of Trust Mechanics → If acceptability or scarcity declines, public confidence drops, forcing economic agents back toward barter or foreign currencies
Evaluation:
→ Modern digital bank transfers meet all key characteristics superiorly, making physical cash less necessary in contemporary economies
Role and Importance of Central Banks:
→ Definition → The primary government-owned financial institution responsible for overseeing the country’s banking system and monetary policy
Core Functions:
→ Issuing Notes and Coins → Holds the sole legal monopoly over printing banknotes and minting currency
→ Implementation of Monetary Policy → Sets base interest rates and controls the domestic money supply to maintain price stability
→ Banker to the Government → Manages government accounts, receives tax revenues, and issues government debt (bonds)
→ Banker to Commercial Banks → Holds cash reserves for commercial banks and operates clearing systems for interbank settlements
→ Lender of Last Resort → Provides emergency liquidity to commercial banks facing temporary cash shortages to prevent financial system collapse
Example:
→ A central bank raises national base interest rates to curb high inflation by discouraging excessive consumer and business borrowing
Analysis:
→ Systemic Stability → Functioning as lender of last resort preserves public confidence in commercial banking stability, preventing bank runs
Evaluation:
→ Central bank independence from political pressure is critical for managing long-term inflation without election-year bias
Role and Importance of Commercial Banks:
→ Definition → Financial institutions profit-driven by providing services to individuals, households, and business entities
Primary Functions:
→ Accepting Deposits → Provides secure accounts (savings and current accounts) for customers to store liquidity
→ Providing Loans → Advances capital to borrowers via mortgages, personal loans, and overdrafts while charging interest
Secondary Functions:
→ Enabling Payments → Processes transactions via debit cards, credit transfers, direct debits, and cheques
→ Foreign Exchange Services → Converts domestic currency into foreign currencies for international business and travel
Example:
→ A commercial bank accepts household savings at 2% interest and lends those funds to a local firm as a business expansion loan at 6% interest
Analysis:
→ Credit Creation → Commercial banks generate economic activity by re-lending deposited funds, increasing investment and consumer spending
Evaluation:
→ Commercial banks face a trade-off between liquidity (keeping cash on hand) and profitability (lending out long-term funds)
