To analyze the USD, make sure that you have the USD in the denominator. For example, if the exchange rate is USD 1.25 per GBP, to analyze the USD value, you need to use GBP 0.8 per USD (=1/1.25). Answer the following questions and show your calculations in the Excel file. 1. What is the appreciation of the USD for the period under analysis for each of the currencies? 2. What is the average monthly appreciation of the USD for the period under analysis for each of the currencies? 3. Enumerate the top-three more volatile exchange rates during this period, calculating and showing the monthly standard deviation. 4. A U.S.-based firm is exporting to each of these countries. Please, identify the countries and currencies where the firm benefit from currency exposure? You need to submit an Excel file with your calculations, and the answers identified.
