AP Macro Foreign Exchange Practice Problems What was a buck worth in this activity? What was a riyal worth? How can we best express the relationship of riyals to bucks? How was the value of riyals to bucks determined in round one? What happened to the value of the riyal relative to the buck in rounds 2 and 3? Did the buck gain in value? In the classroom activity, why do you think the value of the riyal decreased relative to the buck? What caused the change in demand? What sorts of things might cause the demand for a currency to change? Foreign Currency and Exchange The world of foreign currency often seems confusing. Euro, rubles, yen and krona are terms difficult enough to comprehend on their own without adding the task of trying to figure out what each is worth in terms of United States dollars. All of these currencies are money, so all serve the same functions. Money is a medium of exchange, a store of value and a measure of value. As a medium of exchange, money is accepted as a means for purchasing goods and services. Both the consumer and producer agree to the form of money. As a store of value, money can be saved for future use, a characteristic that many items used as barter goods did not have. Where crops would spoil or animals die, money lasts for a long period of time. As a measure of value, money allows us to compare the worth of one object with the worth of another. We can say a car is worth so many dollars, and a CD is worth so many dollars. Foreign currencies all serve the same three functions. Now to the important question: How do we know how much any currency is worth? The simple answer is that money is worth whatever people are willing to exchange for it. This means it is simply a case of supply and demand. If there is little demand for a country’s currency and it is in large supply, the money will be worth less than if there is a high demand for it and a small supply. As an example, if the United States buys more imports, there is a greater supply of U.S. dollars outside the country. As the supply increases, each dollar is worth less. Thus we say the money is devalued. If, on the other hand, there are relatively few U.S. dollars outside the country and/or many foreigners want U.S. currency, each dollar will be worth more. Currency values and exchanges are usually made at currency markets. These are places where countries and banks can find out relative values of different currencies. Each day the values change, and often change several times during a single day. In the past, currency values were set at a rate and maintained for a period of time. Now supply and demand allow constant fluctuations. The situation of foreign exchange is eased somewhat because many financial deals are calculated in United States dollars. At present, approximately 70% of all international trade is invoiced in United States dollars, because business people have found this practice easier. A hundred years ago when the British pound was the most important currency in the world, almost all transactions were recorded in British pounds. Round 1: Round 2: Round 3: Appreciation & Depreciation The currency you want, gains strength. The currency you don’t want, becomes weak. Strong currency appreciates. Weak currency depreciates. The currency you don’t want is the one that you supply more of for exchange. The currency you do want you supply less of for exchange. The currency that you do want is the one you demand more. The currency that you don’t want you demand less. Ways to show appreciation and depreciation D↑/S↓ (want) D↓/S↑ (don’t want) APPRECIATES = STRONG DEPRECIATES = WEAK Side-by-Side Graph Pairs A currency’s value is always relative to another currency’s. Therefore, graphs are always drawn in pairs, side-by-side, with one graph for each currency. Supply and Demand move in the same direction for each graph pair. Increasing supply of one currency to trade, increases demand for the other currency. When one currency appreciates, the other always depreciates. If one currency is strong, the other is weak.

(Consumers will buy more from the country with the relatively lower inflation rate.) U.S. inflation rate = 5% Canada’s inflation rate = 2% This makes the USD weak / strong. Changes in income match changes in consumption. Income Tastes (The more money people make, the more they buy of everything, foreign and domestic.) American’s real income increases by 10%. This makes the USD weak / strong. Changes in popularity of a good match changes in demand for its currency. (The more popular the good, the greater the demand for its currency.) Researchers find that Belgian chocolate cures cancer. This makes the USD weak / strong. IR determine yields (potential profits) from investing in financial assets. Interest Rates (IR↑=>Bond Prices↓=>yields↑, meaning demand for currency increases with IR) Interest rates rise in the United States. Expected Return Investors put money into opportunities for economic growth. (Higher expected returns on a foreign country's stocks, real estate, or production facilities increases international demand for those assets and demand for its currency.) With 9.5% growth in 2015, Ethiopia is projected to grow 10.5% in 2016. Speculation This makes the USD weak / strong. This makes the USD weak / strong. Currency traders will seek to profit from buying a currency at a low rate and selling it at a higher rate in the future. (When any of determinant leads to depreciated currency, an investor will buy it cheap causing the value to rise again.) The Price Level in the United States rises. This makes the USD weak / strong. & or Depreciates The strength of currencies fluctuate. A weak currency buys less (lower purchasing power). A strong currency buys more (greater purchasing power). What will happen to the net export component of the US GDP if… (Explain.) 1. the dollar is weak? 2. the dollar is strong? Assume that American taste for Japanese goods has increased and Americans are now purchasing more imported goods from Japan. The increased demand for Japanese goods means that there is now an increased demand for Japanese yen. Simultaneously there is an increased supply of US dollars “seeking” Japanese yen. Draw two graphs, one for the USD market and one for the Yen market that depicts these situations. Assume that incomes in Europe have fallen dramatically and there is a greatly reduced demand for American goods in Europe. Thus there will be reduced demand for US dollars and simultaneously reduced supply of Euros “seeking” dollars. Show these scenarios drawing a graph of the dollar market and a graph of the euro market. 1.

If the exchange rate between the United States dollar ($) and the British pound (£) changed from $2 per £1 to $3 per £1, and domestic prices in both countries stayed the same, then the United States dollar would (A) Depreciate, making United States imports from Britain more expensive.
