Condition for Nominal Depreciation (δ > 0)

Formula for the Rate of Change of Competitiveness

At the start of a year, the exchange rate between a home currency and a foreign currency is 1.50 units of home currency per unit of foreign currency. By the end of the year, the rate has changed to 1.59 units of home currency per unit of foreign currency. Calculate the rate of depreciation of the home currency over this period.

Calculating a Future Exchange Rate

An exchange rate is quoted as the number of units of a home currency required to purchase one unit of a foreign currency. A depreciation of the home currency means its value has decreased, so the exchange rate number increases. Given the following changes in exchange rates over a one-year period, which scenario represents the largest percentage depreciation of the home currency?

Consider an exchange rate quoted as units of home currency per unit of foreign currency. If this rate moves from 2.0 to 1.8 over a year, this represents a -10% rate of depreciation, signifying that the home currency has appreciated.

An exchange rate is defined as the number of units of a home currency needed to purchase one unit of a foreign currency. Consider two independent scenarios over a one-year period:

• Scenario 1: The exchange rate moves from 2.00 to 2.20.
• Scenario 2: The exchange rate moves from 5.00 to 5.20.

Based on the standard formula for calculating the percentage change, which of the following statements accurately compares the rate of depreciation of the home currency in these two scenarios?

Calculating an Initial Exchange Rate from Depreciation Data

A country's currency exchange rate is expressed as units of home currency per unit of foreign currency. In the first half of the year, the home currency depreciates by 10%. In the second half of the year, it depreciates by an additional 5% relative to its value at mid-year. What is the total rate of depreciation for the entire year?

Comparing Currency Depreciation

An exchange rate is quoted as the number of units of a home currency required to purchase one unit of a foreign currency. Match each exchange rate scenario with the correct rate of depreciation for the home currency over the period.
