Topic 6.5: Changes in the Foreign Exchange Market and Net Exports Definition:
Changes in exchange rates impact a country’s net exports (exports minus imports) and aggregate demand. Currency appreciation and depreciation alter the competitiveness of goods and services in the global market.
Key Concepts to Remember:
1. Currency Appreciation:
● A country’s currency becomes more valuable relative to another.
● Effects on Trade:
● Exports decrease (goods become more expensive for foreign buyers).
● Imports increase (foreign goods become cheaper for domestic consumers).
● Net Exports (Xn): Decrease.
● Effects on Aggregate Demand (AD):
● Lower net exports reduce aggregate demand.
2. Currency Depreciation:
● A country’s currency becomes less valuable relative to another.
● Effects on Trade:
● Exports increase (goods become cheaper for foreign buyers).
● Imports decrease (foreign goods become more expensive for domestic consumers).
● Net Exports (Xn): Increase.
● Effects on Aggregate Demand (AD):
● Higher net exports increase aggregate demand.
Key Terms to Know:
● Net Exports (Xn): The value of exports minus imports.
● Aggregate Demand (AD): The total demand for goods and services in an economy.
● Appreciation: A rise in the value of a currency relative to another.
● Depreciation: A fall in the value of a currency relative to another.
Factors Influencing Exchange Rates and Net Exports:
1. Demand for Domestic Goods:
● Higher demand for a country’s goods → Currency appreciates → Exports decrease.
2. Interest Rates:
● Higher interest rates attract foreign investment → Currency appreciates → Net exports decrease.
3. Speculation:
● If investors expect a currency to appreciate, demand increases → Appreciation occurs.
4. Inflation Rates:
● Higher inflation makes domestic goods less competitive → Exports decrease → Net exports
decrease.
Graphs and Models to Know:
1. Exchange Rate Changes:
● X-Axis: Quantity of currency.
● Y-Axis: Exchange rate.
● Currency appreciation shifts demand for domestic goods left or supply of foreign currency right.
2. Aggregate Demand:
● Show how changes in net exports shift the AD curve:
● Net Exports Increase: AD shifts right.
● Net Exports Decrease: AD shifts left.
Examples of Economic Impact:
1. Appreciation Example:
● The U.S. dollar appreciates:
● U.S. cars become more expensive in Europe → Exports decrease.
● Foreign electronics become cheaper in the U.S. → Imports increase.
● Net exports decrease → AD shifts left.
2. Depreciation Example:
● The euro depreciates:
● European wines become cheaper globally → Exports increase.
● Foreign electronics become more expensive in Europe → Imports decrease.
● Net exports increase → AD shifts right.
Takeaways for Changes in Exchange Rates:
● Currency appreciation typically reduces net exports and slows economic growth.
● Currency depreciation typically boosts net exports and stimulates economic growth.
● Exchange rates are key to understanding global trade patterns and their effect on domestic economies.
