Exchange Rate and the Balance of Payments

Introduction

The exchange rate and balance of payments are central concepts in macroeconomics, affecting international trade, investment, and economic policy. This chapter explains how exchange rates are determined, the effects of exchange rate policies, and the structure of the balance of payments.

The Foreign Exchange Market

Definition and Function

The foreign exchange market is where currencies are traded, enabling international transactions. - Foreign currency includes bank notes, coins, and deposits from other countries. - The market allows individuals and businesses to exchange their domestic currency for foreign currency to buy goods, services, or assets abroad.

Exchange Rates

Key Concepts

- The exchange rate is the price at which one currency is exchanged for another. - Currency depreciation: A fall in the value of one currency relative to another. - Currency appreciation: A rise in the value of one currency relative to another.

Exchange Rate as a Price

Exchange rates are determined in a competitive market by the interaction of demand and supply for currencies.

Demand and Supply in the Foreign Exchange Market

Demand for Canadian Dollars

The demand for Canadian dollars depends on: 1. The exchange rate 2. World demand for Canadian exports 3. Interest rates in Canada and other countries 4. The expected future exchange rate - Law of Demand: Higher exchange rates decrease the quantity of Canadian dollars demanded; lower exchange rates increase it. - Exports effect: Higher exports increase demand for Canadian dollars. - Expected profit effect: If expected profits from holding Canadian dollars rise, demand increases.

Supply of Canadian Dollars

The supply of Canadian dollars depends on: 1. The exchange rate 2. Canadian demand for imports 3. Interest rates in Canada and other countries 4. The expected future exchange rate - Law of Supply: Higher exchange rates increase the quantity of Canadian dollars supplied; lower exchange rates decrease it. - Imports effect: Higher imports increase supply of Canadian dollars. - Expected profit effect: Lower expected profits from holding Canadian dollars increase supply.

Market Equilibrium

Determination of Exchange Rate

The equilibrium exchange rate is where the quantity of Canadian dollars demanded equals the quantity supplied. - If the exchange rate is too high, a surplus of Canadian dollars drives it down. - If the exchange rate is too low, a shortage drives it up. - The market quickly moves to equilibrium.

Exchange Rate Fluctuations

Factors Affecting Demand and Supply

- World demand for Canadian exports: Increased demand shifts the demand curve rightward. - Interest rate differential: Higher Canadian interest rates relative to foreign rates increase demand for Canadian dollars. - Expected future exchange rate: If the expected future exchange rate rises, demand increases and supply decreases.

Changes in Exchange Rate

- If demand increases and supply does not change, the exchange rate rises. - If demand decreases and supply does not change, the exchange rate falls. - If supply increases and demand does not change, the exchange rate falls. - If supply decreases and demand does not change, the exchange rate rises.

Exchange Rate Policy

Types of Exchange Rate Policies

1. Flexible exchange rate: Determined by market forces without central bank intervention. 2. Fixed exchange rate: Pegged by the government or central bank, requiring intervention to maintain the target rate. 3. Crawling peg: Target rate is adjusted periodically by the government or central bank.

Central Bank Intervention

- To maintain a fixed exchange rate, the central bank buys or sells currency to adjust supply. - Persistent intervention is unsustainable in the long run.

Financing International Trade

Balance of Payments Accounts

The balance of payments records a country's international transactions. It consists of three accounts: 1. Current account: Records exports, imports, net interest income, and net transfers. 2. Capital and financial account: Records foreign investment in Canada minus Canadian investment abroad. 3. Official settlements account: Records changes in official reserves.

Key Terms

- Net borrower: A country borrowing more from the rest of the world than it lends. - Net lender: A country lending more to the rest of the world than it borrows. - Debtor nation: Has borrowed more than it has lent over its history. - Creditor nation: Has invested more in the rest of the world than others have invested in it.

Current Account Balance Formula

The current account balance (CAB) is calculated as: - NX is net exports.

Sector Balances and Net Exports

- Government sector balance: (net taxes minus government expenditure) - Private sector balance: (saving minus investment) - Net exports:

Application Example

For Canada in 2016: - Net exports: –$48 billion - Government sector balance: –$38 billion - Private sector balance: –$10 billion - Net exports equals the sum of government and private sector balances.
