Why do we have currency exchange?
• In a foreign exchange market, various national currencies are exchanged for one another so that international trade can take place.
• Germans want euros, Mexicans want pesos, and the Japanese want yen when they sell their products
![Page 4: Exchange Rates. Georgia Council on Economic Education w w w. g c e e. o r g](https://reader035.vdocuments.site/reader035/viewer/2022070412/56649eef5503460f94bff018/html5/thumbnails/4.jpg)
Appreciation v. Depreciation• Appreciation
– The value of one currency rises relative to another currency
– So, if the dollar appreciates relative to the yen, each dollar will be able to buy more yen
• Thus we will be able to buy more Japanese products
• Depreciation– The value of one currency falls relative to another
currency– So, if the dollar depreciates relative to the yen, each dollar
will be able to buy fewer yen• Thus, we will be able to buy fewer Japanese products

A rising US currency makes dollar-priced crude more expensive for foreign buyers and
therefore tends to dampen demand. The dollar was stronger due to speculation
that the European Central Bank will cut interest rates again
in May.

Explain your answer. Use a supply and demand graph to illustrate each situation.
• (A) Montreal hosts the Olympics.
• (B) The rate of inflation in Canada increases relative to the U.S. inflation rate.
• (C) Investors in Quebec purchase substantial real estate in nearby New England and New York.
• (D) A consortium of U.S. oil companies constructs a pipeline in Canada to transport natural gas to the United States.

Answers• (A) Montreal hosts the Olympics.
– Demand shifts right; Appreciate. Visitors exchange their currency for Canadian dollars
• (B) The rate of inflation in Canada increases relative to the U.S. inflation rate.– Supply shifts right; Depreciate. U.S. goods become relatively cheaper, stimulating
imports by Canadians and reducing Canadian exports to the U.S
• (C) Investors in Quebec purchase substantial real estate in nearby New England and NY.– Supply shifts right; Depreciate. Outflow of investment funds requires U.S. dollars
• (D) A consortium of U.S. oil companies constructs a pipeline in Canada to transport natural gas to the United States. – Demand shifts right; Appreciate. investment funds shift from the U.S. to Canada.
• (E) Interest rates rise in the U.S. relative to interest rates in Canada. – Supply shifts right; Depreciate. The U.S. should attract Canadian investment funds
