Study Notes for Chapter 4: Currency Appreciation and Depreciation

Chapter Overview

  • Focus on the concepts related to currency appreciation and depreciation, supply and demand schedules in foreign exchange, and potential speculative investment strategies.

Key Definitions

  • Appreciation: An increase in the value of a currency.

  • Depreciation: A decline in the value of a currency.

  • Percentage Change Calculation:
    extPercentageChange=racextNewPrice−extOldPriceextOldPriceext{Percentage Change} = rac{ ext{New Price} - ext{Old Price}}{ ext{Old Price}}

Currency Values and Calculations

  • Positive percentage change indicates currency appreciation.

  • Negative percentage change indicates currency depreciation.

Examples of Currency Fluctuation

  • Canadian Dollar: Fluctuated between $0.68 and $0.71.

  • Euro: Fluctuated between $1.18 and $1.29 with larger swings.

  • Standard Deviation: The standard deviation of changes was almost one point higher for the euro than the Canadian dollar.

Understanding Exchange Rates

  • Exchange Rate: The price of a currency determined by supply and demand.

    • Direct Quote: Price of a foreign currency in terms of US dollars.

    • Indirect Quote: Price of US dollars in terms of foreign currency.

  • Supply and Demand Curves:

    • Demand curve slopes downward (higher price, lower demand).

    • Supply curve slopes upward (higher price, higher supply).

  • Equilibrium Price: Point where demand and supply curves intersect.

Surplus and Shortage Analysis

  • At $1.60: Surplus (supply > demand) leads to downward pressure on price.

  • At $1.50: Shortage (demand > supply) leads to upward pressure on price.

Determinants of Exchange Rate Equilibrium

  • Factors affecting exchange rates include:

    • Change in inflation.

    • Change in interest rates.

    • Change in income levels (GDP).

    • Change in government controls.

    • Change in market expectations.

Inflation and Interest Rate Relationships

  • It is the relative difference in inflation rates that affects currency values, not the absolute level.

    • Example: If inflation in the US is 5% and in Canada is 10%, the differential is 5%.

    • A change in relative rates can lead to significant currency value shifts.

Speculative Investment Strategies

Understanding Market Expectations

  • Investors may anticipate currency value changes based on expected interest rates and inflation.

  • Example Scenario: If investors expect interest rates to rise, they may purchase currency in advance to capitalize on appreciation.

Speculation Impact on Currency Value

  1. Market Overreaction: Speculators can cause short-term currency value shifts through buying and selling based on forecasts.

  2. Predictions: Investors forecast currency movements based on economic indicators and may buy or sell accordingly.

Case Study: Currency Appreciation and Depreciation

Expected Appreciation of a Currency

  1. Borrow currency expected to depreciate (e.g., US dollar).

  2. Exchange for appreciating currency (e.g., New Zealand dollar) and invest.

  3. Profit from high appreciation rate at the end of the investment period (e.g., converting back to effectively repay loan and gain profit).

Expected Depreciation of a Currency

  1. Borrow the appreciating currency (e.g., New Zealand dollar).

  2. Convert to US dollar for investment.

  3. Calculate the profit by subtracting the loan repayment amount from the final currency conversion amount.

Government Controls Impacting Exchange Rates

  • Trade Barriers: Tariffs and quotas can affect demand for a currency and lead to depreciation.

  • Governments can intervene in foreign exchange to manipulate currency value, impacting investors and market dynamics.

Capital Flows and Their Influence

  • Trade Flows: Changes in trade between countries can have a significant impact on currency value.

  • Capital Flows: Interest rates and investment behaviors determine how much money flows between countries, impacting exchange rates.

Summary of Factors Influencing Currency Exchange Rates

  • ⬆ Trade relationships increases impact of inflation on exchange rates.

  • ⬆ Capital investments magnify the impact of interest rate changes.

  • Factors influencing currency exchange are typically interconnected; isolation is theoretical rather than practical.

Conclusion

  • Understanding the concepts of currency values, exchange rates, and speculative strategies is crucial for navigating the complexities of international economics.
