Solution to Continuing Case Problem: Blades, Inc. Case Study Two
Assessing Future Exchange Rate Movements
1. How are percentage changes in a currency’s value measured? Illustrate your answer numerically by assuming a change in the Thai baht’s value from a value of $0.022 to $0.026. ANSWER: The percentage change in a currency’s value is measured as follows:
where S denotes the spot rate, and St −1 denotes the spot rate as of the earlier date. A positive percentage change represents appreciation of the foreign currency, while a negative percentage change represents depreciation. In the example provided, the percentage change in the Thai baht would be:
That is, the baht would be expected to appreciate by 18.18%. 2. What are the basic factors that determine the value of a currency? In equilibrium, what is the relationship between these factors? ANSWER: The basic factors that determine the value of a currency are the supply of the currency for sale and the demand for the currency. A high level of supply of a currency generally decreases the currency’s value, while a high level of demand for a currency increases its value. In equilibrium, the supply of the currency equals the demand for the currency. 3. How might the relatively high levels of inflation and interest rates have affected the baht’s value? (Assume a constant level of U.S. inflation and interest rates.) ANSWER: The baht would be affected both by inflation levels and interest rates in Thailand relative to levels of these variables in the U.S. A high level of inflation tends to result in currency depreciation, as it would increase the Thai demand for U.S. goods, causing an increase in the Thai demand for dollars. Furthermore, a relatively high level of Thai inflation would reduce the U.S. demand for Thai goods, causing an increase in the supply of baht for sale. Conversely, the high level of interest rates in Thailand may cause appreciation of the baht relative to the dollar. A relatively high level...
