Money, Banking & Trade: Functions, Flows & Global Links

Unit 8 of Applied Economics: Explores how money works as a medium of exchange, the roles of banks (central and commercial), and Nepal’s trade dynamics—with real-world ties to eSewa, NEPSE, and global supply chains.

TAKEAWAYS:

  • Money’s primary functions (medium of exchange, store of value) and secondary functions (unit of account, standard of deferred payment) are critical for digital payments like eSewa.
  • Central banks (Nepal Rastra Bank) control money supply and interest rates—directly affecting loans for Daraz’s inventory or Pathao’s fleet purchases.
  • Balance of trade (exports vs. imports) and balance of payments (capital flows) explain why Nepal imports smartphones but exports remittances.
  • Commercial banks (NMB, Global IME) use fractional reserve banking to create credit, which fuels Nepal’s construction boom or YouTube’s ad revenue.
  • Exchange rates (NPR/USD) impact Daraz’s import costs and NTC’s foreign equipment purchases—tracked via demand-supply curves for forex.
  • International trade theories (comparative advantage) explain why Nepal exports jute but imports electronics—visualized via PPF curves.

1. Money: Functions and Types

Money is the lifeblood of any economy, enabling transactions without barter. It serves four key functions:

Primary Functions

  1. Medium of Exchange

    • Money acts as an intermediary in transactions, eliminating the need for double coincidence of wants.
    • Example: When you pay for a Daraz order using eSewa, money (digital or cash) facilitates the exchange without requiring you to own the product first.
  2. Store of Value

    • Money retains purchasing power over time, allowing savings for future use.
    • Example: Remittances sent home by Nepali workers in the Gulf are stored as NPR savings, preserving their value until spent.

Secondary Functions

  1. Unit of Account

    • Money provides a common measure to value goods and services.
    • Example: Prices of Pathao rides or Ncell data plans are quoted in NPR, making comparisons easy.
  2. Standard of Deferred Payment

    • Money allows credit transactions (loans, mortgages) by standardizing future payments.
    • Example: A bank loan for a NEPSE stock purchase is repaid in future installments, using money as the deferred payment standard.

    E -->|e.g.| I[Repaying NMB loan in installments]

Types of Money

Money evolves from commodity money (gold, silver) to fiat money (paper/currency backed by government decree). Today, Nepal uses a fiat currency system (NPR), while digital payments (eSewa, Khalti) represent electronic money.

Type of Money Definition Example in Nepal
Commodity Money Money with intrinsic value (e.g., gold) Pre-1932: Silver coins
Fiat Money Money without intrinsic value, backed by trust NPR notes, coins
Electronic Money Digital representation of currency eSewa, Khalti, mobile wallets
Cryptocurrency Decentralized digital currency Bitcoin (rarely used in Nepal)

EXAMPLE: eSewa’s Role as Electronic Money eSewa enables peer-to-peer transactions without physical cash. When you pay a Pathao driver, eSewa processes the transfer instantly, acting as electronic money while NPR remains the fiat currency.


2. Banking System: Central and Commercial Banks

Banks are the backbone of modern economies, facilitating savings, lending, and monetary policy.

A. Central Bank: Nepal Rastra Bank (NRB)

Functions:

  1. Issuer of Currency: Controls money supply (e.g., printing NPR notes).
  2. Banker to Government: Manages public debt and treasury operations.
  3. Lender of Last Resort: Provides emergency liquidity to commercial banks (e.g., during COVID-19).
  4. Regulator of Banks: Ensures stability (e.g., capital adequacy rules for NMB, Global IME).
  5. Monetary Policy: Adjusts interest rates (e.g., repo rate) to control inflation.

Tools of Monetary Policy:

  • Open Market Operations: Buying/selling government securities to adjust money supply.
  • Repo Rate: Interest rate at which NRB lends to banks (currently ~6% as of 2023).
  • Cash Reserve Ratio (CRR): Fraction of deposits banks must hold (e.g., 7% in 2023).

B. Commercial Banks: How They Create Money

Commercial banks (e.g., NMB, Global IME, Standard Chartered) create money through fractional reserve banking.

Process:

  1. A customer deposits ₹10,000.
  2. Bank holds ₹2,000 (CRR = 20%) and lends ₹8,000.
  3. Borrower spends ₹8,000 → new deposit → bank lends ₹6,400 (after CRR).
  4. Money Multiplier Effect: Initial ₹10,000 creates ₹50,000 in the economy (1/0.2 = 5).

Formula:

Example: If NRB sets CRR = 10%, a ₹100 deposit can generate ₹1,000 in the economy.

  E --> F["₹50,000 Total Money"]
  F -->|"Formula"| G["Money Multiplier = 1/CRR"]

Fractional reserve banking with 20% CRR


Functions of Commercial Banks

Function Description Example
Accepting Deposits Collects savings and current accounts. NMB’s savings account for remittances.
Lending Provides loans for business/individuals. Daraz’s working capital loan.
Payment Services Facilitates transfers (NEFT, eSewa). Paying Ncell bill via bank app.
Credit Creation Expands money supply via loans. Pathao’s vehicle financing.
Investment Services Sells mutual funds, stocks. NEPSE trading via bank account.

EXAMPLE: Daraz’s Working Capital Loan Daraz needs ₹50 million to stock inventory. It borrows from a commercial bank (e.g., Global IME) at 12% annual interest. The bank uses ₹10 million of customer deposits (CRR = 10%) to lend ₹90 million (after holding ₹10 million). Daraz repays ₹56 million (principal + interest) in 1 year.


3. International Trade: Balance of Trade and Payments

Trade is the engine of global growth, but imbalances can disrupt economies.

A. Balance of Trade (BOT)

Definition: Difference between exports (goods/services sold abroad) and imports (goods/services bought from abroad).

Types:

  1. Favorable Balance of Trade (Trade Surplus): Exports > Imports.
    • Example: Nepal’s jute exports to China (₹5 billion in 2022).
  2. Unfavorable Balance of Trade (Trade Deficit): Imports > Exports.
    • Example: Nepal’s smartphone imports (₹20 billion in 2022).

FIGURE 4: Nepal’s Trade Balance (2022)

mermaid
pie title Nepal’s Trade Balance (2022)
    "Exports: ₹100B" : 30
    "Imports: ₹200B" : 70

B. Balance of Payments (BOP)

Definition: Comprehensive record of all economic transactions between a country and the rest of the world (includes trade, services, capital flows, remittances).

Components:

  1. Current Account: Trade (goods/services), income (remittances), transfers.
    • Example: Nepali workers’ ₹50 billion remittances in 2022.
  2. Capital Account: Foreign investment, loans, portfolio flows.
    • Example: NEPSE’s ₹1 trillion market capitalization.
  3. Financial Account: Changes in foreign assets/liabilities.
    • Example: NTC’s foreign debt for 5G infrastructure.

Types of BOP:

Type Description Example
Favorable BOP Total credits > total debits. Remittances cover trade deficit.
Unfavorable BOP Total debits > total credits. Nepal’s reliance on foreign loans.

EXAMPLE: Nepal’s Remittance-Driven BOP In 2022:

  • Exports: ₹80 billion (jute, textiles).
  • Imports: ₹220 billion (oil, electronics).
  • Remittances: ₹50 billion (current account credit).
  • Net BOP: (₹80B - ₹220B) + ₹50B = ₹-90B deficit, but remittances partially offset it.

C. Exchange Rates and Trade

Exchange rates determine the value of NPR against foreign currencies (e.g., USD). They affect trade competitiveness.

Determinants of Exchange Rates:

  1. Demand for Imports: High demand for USD (e.g., for oil imports) → NPR depreciates.
  2. Remittances: Inflows of USD → NPR appreciates.
  3. Foreign Investment: Capital inflows (e.g., NEPSE IPOs) → NPR strengthens.

FIGURE 5: Demand-Supply of NPR/USD

mermaid
pie title NPR/USD Exchange Rate (2023)
    "Demand for USD (Imports)" : 60
    "Supply of USD (Remittances)" : 40

Dashed line: Equilibrium at ₹120/USD.


EXAMPLE: Oil Import Costs

  • 2022: NPR/USD = ₹115. Oil import bill = ₹200 billion (₹100B worth of oil at $60/barrel).
  • 2023: NPR/USD = ₹125. Same oil bill now costs ₹220 billion due to NPR depreciation.

4. International Trade Theories

Theories explain why countries trade and specialize.

A. Absolute Advantage (Adam Smith)

  • A country should produce goods where it is most efficient.
  • Example: Nepal produces jute (low-cost labor) while importing smartphones (high-cost production).

B. Comparative Advantage (David Ricardo)

  • A country should produce goods where it has the least disadvantage.
  • Example: Nepal exports textiles (lower opportunity cost than electronics).

FIGURE 6: Comparative Advantage (PPF)

mermaid
pie title Nepal’s PPF (Textiles vs. Electronics)
    "Textiles: 100 units" : 60
    "Electronics: 50 units" : 40

Nepal specializes in textiles (lower opportunity cost).


C. Terms of Trade

Definition: Ratio of export prices to import prices.

  • Favorable: Export prices rise faster than import prices.
  • Example: Nepal’s jute prices rise → better terms of trade.

5. Nepal’s Trade Partners and Barriers

A. Major Trade Partners

Partner Exports to Nepal Imports from Nepal
India Oil, electronics Jute, textiles
China Machinery, steel Hydropower equipment
USA Medical equipment Remittances (indirectly)

B. Trade Barriers

  1. Tariffs: Taxes on imports (e.g., 20% tariff on smartphones).
  2. Quotas: Limits on import quantities (e.g., sugar imports).
  3. Non-Tariff Barriers: Bureaucracy, customs delays.

Relative impact of different trade barriers on Nepal’s imports

Example: Nepal’s 20% tariff on smartphones makes them expensive, reducing imports but hurting consumers.


In the Real World

  1. eSewa’s Digital Money

    • Idea: Electronic money (secondary function of money).
    • How: eSewa’s app uses digital tokens to facilitate instant payments, reducing reliance on cash. When you pay a Pathao driver, eSewa acts as a medium of exchange while NPR remains the fiat currency.
  2. NEPSE’s Stock Market and Capital Flows

    • Idea: Balance of Payments (Capital Account).
    • How: Foreign investors buying NEPSE stocks (e.g., Ncell, Siddhartha Hospital) contribute to Nepal’s financial account, improving BOP. In 2022, ₹100 billion in foreign investment flowed into NEPSE, partially offsetting trade deficits.
  3. Pathao’s Vehicle Loans and Fractional Reserve Banking

    • Idea: Commercial bank lending and money creation.
    • How: Pathao takes a ₹5 million loan from Global IME to expand its fleet. The bank lends ₹5 million using ₹1 million of customer deposits (CRR = 20%). This loan enables Pathao to hire drivers, creating jobs and stimulating the economy.

Exam Tip

This unit tests conceptual understanding and real-world application. Focus on:

  1. Definitions: Know the difference between balance of trade (goods only) and balance of payments (all transactions).
  2. Diagrams: Draw demand-supply curves for exchange rates and fractional reserve banking flows.
  3. Numerical Problems: Practice money multiplier calculations and BOP balance sheets.
  4. Nepal-Specific Examples: Use remittances, NEPSE, or eSewa to explain concepts.
  5. Policy Links: Connect NRB’s repo rate to inflation or commercial bank lending to business growth.

Common Pitfalls:

  • Confusing absolute advantage (efficiency) with comparative advantage (opportunity cost).
  • Forgetting that BOP includes remittances and capital flows, not just trade.
  • Misapplying money multiplier (use CRR correctly).

Worked Example for Practice: If NRB sets CRR = 15% and a bank receives ₹200 million in deposits, calculate the maximum money it can create. Solution:

  1. Legal Reserve = ₹200M × 15% = ₹30M.
  2. Loanable Funds = ₹200M - ₹30M = ₹170M.
  3. Money Multiplier = 1/0.15 ≈ 6.67.
  4. Total Money Created = ₹170M × 6.67 ≈ ₹1,133.9M.
