Exchange Rates - AP Macroeconomics

  1. Based on the exchange rate shown, assume the euro area is the domestic economy and the exchange rate is quoted as U.S. dollars per €1. The exchange rate changes from €1 = $2 in Quarter 1 to €1 = $1 in Quarter 2. Which statement correctly describes the change in the euro and the effect on the dollar price of euro-area exports to the United States (priced in euros), holding other factors constant?
    Answer: The euro depreciated, and euro-area exports become cheaper in dollars. An exchange rate indicates how many units of one currency equal one unit of another currency. When the exchange rate changes from €1 = $2 to €1 = $1, each euro now exchanges for fewer dollars (1 instead of 2), meaning the euro has depreciated relative to the dollar. When a currency depreciates, that country's exports become cheaper for foreign buyers because they need fewer of their own currency to purchase the depreciated currency. A common misconception is focusing only on the numbers without considering which currency is the base - here, the euro is the base currency and its value fell. The strategy is to identify the domestic currency (euro), determine its direction (depreciated because €1 buys fewer dollars), and then assess the effect on exports (cheaper in dollars for U.S. buyers).
  2. Based on the exchange rate shown, assume South Korea is the domestic country and the exchange rate is quoted as Korean won per 1 U.S. dollar. The exchange rate changes from 1 \= 2,000 KRW in Period 1 to 1 \= 1,000 KRW in Period 2. Which statement correctly describes what happened to the won and one likely implication for South Korean exports to the United States (holding South Korean prices constant in won)?
    Answer: The won appreciated, and South Korean exports become more expensive for U.S. buyers. An exchange rate indicates the price of one currency in terms of another. When the exchange rate changes from $1 \= 2,000 KRW to $1 \= 1,000 KRW, one U.S. dollar now buys fewer Korean won, which means the dollar has depreciated and the won has appreciated (strengthened). When the won appreciates, South Korean exports to the United States become more expensive for U.S. buyers because Americans need more dollars to buy the same Korean goods priced in won. A common misconception is focusing on the large numbers and losing track of the direction—a decrease from 2,000 to 1,000 means the dollar buys less, not more. The strategy is to identify the base currency ($1), determine if it purchases more or less of the other currency, then apply the opposite direction to that currency.
  3. Based on the exchange rate shown (quoted as Swiss francs per 1 U.S. dollar), which statement correctly describes what happened to the Swiss franc and the likely effect on Swiss import prices from the United States (in francs)? Period 1: 1 USD = 1.00 CHF Period 2: 1 USD = 0.80 CHF
    Answer: The Swiss franc appreciated, and Swiss imports from the United States tend to become cheaper in francs. An exchange rate specifies the amount of one currency obtainable for another, here as Swiss francs per U.S. dollar. Appreciation means a currency strengthens and can acquire more foreign units, while depreciation means it weakens. The rate fell from 1.00 to 0.80 CHF per USD, meaning the Swiss franc appreciated against the dollar, since fewer francs are needed for one USD or, equivalently, one franc buys more dollars. Consequently, Swiss imports from the U.S. become cheaper in francs. A common misconception is mistaking rate decreases for deflation instead of currency strength. Use the strategy: state the currency first, then direction, like 'franc appreciated,' to assess import price dynamics.
  4. Based on the exchange rate shown, suppose the United States is the domestic economy and the exchange rate is quoted as foreign currency per $1. If the exchange rate changes from $1 = 2 Canadian dollars (CAD) in Year 1 to $1 = 3 CAD in Year 2, which statement correctly describes the change and its likely effect on U.S. imports from Canada (priced in CAD), holding other factors constant?
    Answer: The U.S. dollar appreciated, and U.S. imports from Canada become cheaper in dollars. An exchange rate shows how much of one currency can be exchanged for another currency. When the exchange rate changes from $1 = 2 CAD to $1 = 3 CAD, each U.S. dollar now buys more Canadian dollars (3 instead of 2), meaning the U.S. dollar has appreciated relative to the Canadian dollar. When your currency appreciates, foreign goods become cheaper because you need fewer dollars to buy the same amount of foreign currency. A common misconception is confusing which currency appreciated when the number increases - remember that if one dollar buys MORE foreign currency, the dollar has gotten stronger. The key strategy is to state the currency first (U.S. dollar), then identify the direction (appreciated because it buys more CAD), and finally determine the effect on imports (cheaper in dollars).
  5. Based on the exchange rate shown, where the price of one U.S. dollar in Indian rupees changes from 1 USD=80 INR1\ \text{USD} = 80\ \text{INR} in Period 1 to 1 USD=70 INR1\ \text{USD} = 70\ \text{INR} in Period 2, which statement is correct about the U.S. dollar and the likely effect on U.S. consumers buying Indian goods (holding other factors constant)?
    Answer: The U.S. dollar depreciated, and Indian goods become more expensive in dollars for U.S. consumers. An exchange rate represents how much of one currency can be exchanged for another. When the USD/INR rate decreases from 80 to 70, it means one U.S. dollar now buys only 70 Indian rupees instead of 80. This is a depreciation of the U.S. dollar because it has weakened against the rupee. When the dollar depreciates, Indian goods become more expensive for U.S. consumers because they need more dollars to buy the same amount of rupees to purchase Indian products. A common misconception is thinking that fewer foreign currency units per dollar means things get cheaper - it's actually the opposite. The key strategy is to state the currency first (U.S. dollar), then trace through the logic (fewer rupees per dollar means depreciation, which makes imports more expensive).
  6. Based on the exchange rate shown in the table (quoted as Swedish kronor per 1 U.S. dollar), which statement correctly describes what happened to the U.S. dollar and the dollar price of Swedish imports into the United States? Exchange Rate: SEK per $1 (USD) - Quarter 1: 10 SEK per $1 - Quarter 2: 8 SEK per $1
    Answer: The U.S. dollar depreciated, and Swedish imports became more expensive in U.S. dollars. An exchange rate specifies how much of one currency is needed to buy a unit of another, quoted here as Swedish kronor per U.S. dollar, showing kronor per dollar. Appreciation strengthens a currency, allowing it to buy more foreign units, while depreciation weakens it, buying fewer. The table shows a decline from 10 SEK per $1 to 8 SEK per $1, signifying the U.S. dollar depreciated as it now buys fewer kronor. As a result, Swedish imports into the U.S. become more expensive in dollars, requiring more dollars for the same kronor-priced goods. People sometimes misconceive that a falling rate means appreciation, but it indicates depreciation for the dollar in this quoting convention. Apply this strategy: state the currency first (e.g., U.S. dollar) followed by the direction (depreciated) to clarify effects on import costs.
  7. Based on the exchange rate shown, assume Australia is the domestic economy and the exchange rate is quoted as Australian dollars (AUD) per $1. The exchange rate changes from $1 = 2 AUD in Period 1 to $1 = 1 AUD in Period 2. Which statement correctly describes the change in the AUD and the likely effect on Australia's imports from the United States (priced in dollars), holding other factors constant?
    Answer: The AUD appreciated, and U.S. imports into Australia become cheaper in AUD. An exchange rate represents the relative value between two currencies in the foreign exchange market. When the exchange rate changes from $1 = 2 AUD to $1 = 1 AUD, each dollar now buys fewer Australian dollars (1 instead of 2), which means the dollar has depreciated and the Australian dollar has appreciated. When the AUD appreciates against the dollar, U.S. goods priced in dollars become cheaper in AUD terms because Australians need fewer AUD to buy each dollar required for U.S. imports. A common misconception is thinking that a currency appreciation makes imports more expensive, but appreciation actually increases purchasing power over foreign goods. The strategy is to state the domestic currency first (AUD), identify the direction (appreciated because fewer AUD buy $1), then determine the effect on imports (U.S. goods become cheaper in AUD).
  8. Based on the exchange rate shown, assume Canada is the domestic country and the exchange rate is quoted as Canadian dollars per $1 U.S. The exchange rate changes from $1 = 2 CAD in Period 1 to $1 = 1 CAD in Period 2. Which statement correctly describes what happened to the Canadian dollar and one likely implication for Canadian imports from the United States (holding U.S. prices constant in dollars)?
    Answer: The Canadian dollar appreciated, and Canadian imports become cheaper in Canadian dollars. An exchange rate shows the relative value between two currencies. When the exchange rate changes from $1 = 2 CAD to $1 = 1 CAD, one U.S. dollar now buys fewer Canadian dollars, which means the U.S. dollar has depreciated and the Canadian dollar has appreciated (strengthened). When the Canadian dollar appreciates, Canadian imports from the United States become cheaper in Canadian dollar terms because Canadians need fewer Canadian dollars to buy the same U.S. goods. A common misconception is thinking that a decrease in the exchange rate number always means the quoted currency depreciated. The strategy is to focus on the base currency ($1), determine if it buys more or less, then apply the opposite direction to the other currency.
  9. Based on the exchange rate shown (quoted as Canadian dollars per 1 euro), which statement correctly describes the change in the euro and its likely effect on euro-area exports to Canada? Exchange Rate: CAD per €1 (EUR) - Month 1: 1.50 CAD per €1 - Month 2: 1.60 CAD per €1
    Answer: The euro appreciated, and euro-area exports to Canada became more expensive in Canadian dollars. The exchange rate is defined as the rate at which one currency can be exchanged for another, here given as Canadian dollars per euro, reflecting how many CAD one euro can buy. When a currency appreciates, its value rises, enabling it to purchase more of another currency; depreciation occurs when it buys less. According to the stimulus, the rate increased from 1.50 CAD per €1 to 1.60 CAD per €1, indicating the euro appreciated by buying more CAD. This makes euro-area exports to Canada more expensive in Canadian dollars, as Canadians need more CAD to buy euros for those goods. A misconception often arises when people think appreciation always cheapens exports, but it actually raises their foreign price. Remember the transferable strategy: name the currency first (e.g., euro) and then the direction (appreciated) to systematically evaluate trade implications.
  10. Based on the exchange rate shown, assume India is the domestic economy and the exchange rate is quoted as rupees (INR) per $1. The exchange rate changes from $1 = 50 INR in Year 1 to $1 = 40 INR in Year 2. Which statement correctly describes the change in the rupee and the likely change in the rupee purchasing power over U.S. goods priced in dollars, holding other factors constant?
    Answer: The rupee appreciated, and each rupee buys more U.S. goods than before. An exchange rate indicates the price of one currency in terms of another currency. When the exchange rate changes from $1 = 50 INR to $1 = 40 INR, each dollar now buys fewer rupees (40 instead of 50), which means the dollar has depreciated and the rupee has appreciated. When the rupee appreciates, each rupee has greater purchasing power over U.S. goods because Indians need fewer rupees to buy the dollars required to purchase U.S. products. A common misconception is thinking that nominal exchange rate changes don't affect real purchasing power, but exchange rates directly determine how much foreign goods cost in domestic currency. The strategy is to state the domestic currency first (rupee), identify the direction (appreciated because fewer INR buy $1), then determine the effect on purchasing power (each rupee buys more U.S. goods).
  11. Based on the exchange rate shown, where the price of one U.S. dollar in Chinese yuan changes from 1 USD=6 CNY1\ \text{USD} = 6\ \text{CNY} in Period 1 to 1 USD=8 CNY1\ \text{USD} = 8\ \text{CNY} in Period 2, which statement is correct about the Chinese yuan and the likely effect on U.S. exports to China (holding other factors constant)?
    Answer: The yuan depreciated, and U.S. exports to China tend to rise as they become cheaper in yuan. An exchange rate indicates how much of one currency can be exchanged for another. When the USD/CNY rate increases from 6 to 8, it means one U.S. dollar now buys 8 Chinese yuan instead of 6. From the Chinese perspective, this means the yuan has depreciated because it takes more yuan to buy one dollar. When the yuan depreciates, U.S. exports to China become cheaper in yuan terms because Chinese buyers need fewer yuan (relative to their income) to buy the same dollar-priced U.S. goods. A common misconception is focusing only on the dollar's strength rather than considering both currencies - the yuan's depreciation is the dollar's appreciation. The transferable strategy is to state the currency first (yuan), then connect its depreciation to making U.S. goods more affordable for Chinese buyers.
  12. Based on the exchange rate shown, where the price of one U.S. dollar in South African rand changes from 1 USD=10 ZAR1\ \text{USD} = 10\ \text{ZAR} in Period 1 to 1 USD=5 ZAR1\ \text{USD} = 5\ \text{ZAR} in Period 2, which statement is correct about the U.S. dollar and the purchasing power of U.S. tourists in South Africa (holding other factors constant)?
    Answer: The U.S. dollar depreciated, and U.S. tourists can buy fewer South African goods for each dollar. An exchange rate shows the value of one currency expressed in another currency. When the USD/ZAR rate decreases from 10 to 5, it means one U.S. dollar now buys only 5 South African rand instead of 10. This is a depreciation of the U.S. dollar because it has lost value against the rand. When a currency depreciates, tourists holding that currency can buy fewer goods in the foreign country because each dollar commands less foreign currency to make purchases. A common misconception is thinking that exchange rate changes affect only trade in goods - they equally impact tourist purchasing power. The key strategy is to state the currency first (U.S. dollar), then trace the effect (fewer rand per dollar means less purchasing power in South Africa).
  13. Based on the exchange rate shown in the table (quoted as U.S. dollars per 1 Swiss franc), which statement correctly describes what happened to the Swiss franc and the dollar price of Swiss exports sold in the United States? Exchange Rate: $ per 1 CHF - Day 1: $1.00 per CHF - Day 2: $1.20 per CHF
    Answer: The Swiss franc appreciated, and Swiss exports became more expensive in U.S. dollars. An exchange rate indicates the relative value between currencies, here quoted as U.S. dollars per Swiss franc, meaning dollars per franc. Appreciation means a currency's value rises, enabling it to buy more of another; depreciation means it buys less. The stimulus shows the rate climbing from $1.00 per CHF to $1.20 per CHF, indicating the Swiss franc appreciated as it now commands more dollars. Thus, Swiss exports to the U.S. become more expensive in dollars, since more dollars are needed for franc-priced items. One misconception is thinking this rate increase depreciates the franc, but it actually reflects appreciation. To avoid confusion, always state the currency first (e.g., Swiss franc) and then the direction (appreciated) for clear analysis of export pricing.
  14. Based on the exchange rate shown, suppose the United States is the domestic country and the exchange rate is quoted as Indian rupees per $1. The exchange rate changes from $1 = 50 INR in Year 1 to $1 = 100 INR in Year 2. Which statement correctly describes what happened to the U.S. dollar and one likely implication for U.S. exports to India (holding U.S. prices constant in dollars)?
    Answer: The dollar appreciated, and U.S. exports become more expensive for Indian buyers. An exchange rate shows how much foreign currency one unit of domestic currency can buy. When the exchange rate changes from $1 = 50 INR to $1 = 100 INR, one U.S. dollar now buys more Indian rupees, which means the dollar has appreciated (strengthened) relative to the rupee. When the dollar appreciates, U.S. exports to India become more expensive for Indian buyers because Indians need more rupees to buy the same U.S. goods priced in dollars. A common misconception is thinking that a higher exchange rate number always benefits the domestic country—while it makes imports cheaper, it hurts export competitiveness. The key strategy is to state the base currency ($1), check if it buys more or less, then determine how this affects export prices for foreign buyers.
  15. Based on the exchange rate shown, assume Brazil is the domestic economy and the exchange rate is quoted as Brazilian reais (BRL) per $1. The exchange rate changes from $1 = 2 BRL in Semester 1 to $1 = 4 BRL in Semester 2. Which statement correctly identifies the change and the likely effect on the BRL price of U.S.-made capital equipment sold in Brazil (priced in dollars), holding other factors constant?
    Answer: The real depreciated, and U.S. equipment becomes more expensive in reais. An exchange rate shows how much of one currency equals one unit of another currency. When the exchange rate changes from $1 = 2 BRL to $1 = 4 BRL, each dollar now buys more Brazilian reais (4 instead of 2), meaning the dollar has appreciated and the real has depreciated. When the real depreciates, U.S. goods priced in dollars become more expensive in real terms because Brazilian buyers need more reais to purchase each dollar needed for U.S. equipment. A common misconception is attributing the price change to the dollar's movement rather than focusing on the domestic currency's depreciation. The strategy is to identify the domestic currency (real), determine its direction (depreciated because more BRL are needed per dollar), and assess the impact on imports (U.S. equipment becomes more expensive in reais).
  16. Based on the exchange rate shown, assume Brazil is the domestic country and the exchange rate is quoted as Brazilian reais per $1 U.S. The exchange rate changes from $1 = 4 BRL in Quarter 1 to $1 = 2 BRL in Quarter 2. Which statement correctly describes what happened to the real (BRL) and one likely implication for Brazilian imports from the United States (holding U.S. prices constant in dollars)?
    Answer: The real appreciated, and Brazilian imports become cheaper in reais. An exchange rate shows the price of one currency expressed in another currency. When the exchange rate changes from $1 = 4 BRL to $1 = 2 BRL, one U.S. dollar now buys fewer Brazilian reais, which means the dollar has depreciated and the real has appreciated (strengthened). When the real appreciates, Brazilian imports from the United States become cheaper in real terms because Brazilians need fewer reais to buy the same U.S. goods priced in dollars. A common misconception is thinking that when the exchange rate number decreases, the non-base currency must have depreciated. The strategy is to state which currency is held constant ($1), determine if it buys more or less, then apply the opposite movement to the other currency.
  17. Based on the exchange rate shown, where the price of one euro in Japanese yen changes from 1 EUR=150 JPY1\ \text{EUR} = 150\ \text{JPY} in Period 1 to 1 EUR=120 JPY1\ \text{EUR} = 120\ \text{JPY} in Period 2, which statement is correct about the euro from the European perspective and the purchasing power of European consumers in Japan (holding other factors constant)?
    Answer: The euro depreciated, and European consumers can buy fewer Japanese goods for each euro. An exchange rate expresses the price of one currency in terms of another currency. When the EUR/JPY rate decreases from 150 to 120, it means one euro now buys only 120 Japanese yen instead of 150 yen. This represents a depreciation of the euro because it has lost value relative to the yen. When a currency depreciates, consumers holding that currency can buy fewer foreign goods because each euro now commands less foreign currency. A common misconception is thinking that a smaller exchange rate number always means the currency is weaker - what matters is the direction of change. The transferable strategy is to state the currency first (euro), then identify the direction of change (fewer yen per euro means depreciation).
  18. Based on the exchange rate shown, assume Australia is the domestic country and the exchange rate is quoted as U.S. dollars per A$1. The exchange rate changes from A$1 = $1 in Month 1 to A$1 = $2 in Month 2. Which statement correctly describes what happened to the Australian dollar and one likely implication for Australian exports to the United States (holding Australian prices constant in Australian dollars)?
    Answer: The Australian dollar appreciated, and Australian exports become more expensive for U.S. buyers. An exchange rate represents the relative value between two currencies. When the exchange rate changes from A$1 = $1 to A$1 = $2, one Australian dollar now buys more U.S. dollars, which means the Australian dollar has appreciated (strengthened) relative to the U.S. dollar. When the Australian dollar appreciates, Australian exports to the United States become more expensive for U.S. buyers because Americans need more U.S. dollars to purchase the same Australian goods priced in Australian dollars. A common misconception is thinking currency appreciation helps exporters—it actually makes their products less competitive abroad. The strategy is to identify the base currency (A$1), see if it commands more or less of the other currency, then trace the impact on export competitiveness.
  19. Based on the exchange rate shown in the table (quoted as foreign currency per 1 U.S. dollar), which statement correctly describes the change in the value of the U.S. dollar and its likely effect on U.S. imports from Mexico? Exchange Rate: Mexican pesos (MXN) per $1 (USD) - Period 1: 20 MXN per $1 - Period 2: 25 MXN per $1
    Answer: The U.S. dollar appreciated, and U.S. imports from Mexico became cheaper in dollars. An exchange rate is the price of one currency in terms of another, here quoted as Mexican pesos per U.S. dollar, indicating how many pesos one dollar can buy. Currency appreciation occurs when a currency's value increases relative to another, allowing it to purchase more of the foreign currency, while depreciation means it buys less. In this case, the exchange rate rose from 20 MXN per $1 to 25 MXN per $1, showing the U.S. dollar appreciated as it now buys more pesos. This appreciation makes U.S. imports from Mexico cheaper in dollars because fewer dollars are needed to obtain the pesos required for Mexican goods. A common misconception is confusing the direction of change with the currency's value; for instance, some might think a higher number means depreciation for the dollar, but it actually signifies appreciation. To analyze such changes effectively, always state the currency first (e.g., U.S. dollar) and then the direction (appreciated), which helps clarify impacts on trade and travel.
  20. Based on the exchange rate shown, where the price of one Swiss franc in U.S. dollars changes from 1 CHF=1 USD1\ \text{CHF} = 1\ \text{USD} in Period 1 to 1 CHF=2 USD1\ \text{CHF} = 2\ \text{USD} in Period 2, which statement is correct about the U.S. dollar (from the U.S. perspective) and the likely effect on U.S. imports from Switzerland (holding other factors constant)?
    Answer: The U.S. dollar depreciated, and Swiss imports become more expensive in dollars for U.S. consumers. An exchange rate indicates the price of one currency in terms of another. When the CHF/USD rate increases from 1 to 2, it means one Swiss franc now costs 2 U.S. dollars instead of 1. From the U.S. perspective, this means the U.S. dollar has depreciated because it takes more dollars to buy one franc. When the dollar depreciates, Swiss imports become more expensive for U.S. consumers because they need more dollars to buy the francs necessary to purchase Swiss goods. A common misconception is not recognizing whose perspective matters - the question asks about the U.S. dollar from the U.S. perspective. The key strategy is to state the currency first (U.S. dollar), then determine if it buys more or less foreign currency (needing more USD per CHF means depreciation).
