For the last several year, U.S. short-term interest rates have been close to zero. A colleague in the finance department of your multinational company (MNC) is advocating that your company use more dollar-denominated short-term debt to cover short-term funding needs for subsidiaries in foreign countries that generate positive earnings. Your colleague says this is a win-win for the company because the company can finance at lower costs without taking on any extra risk. Is your colleague correct? Explain why or why not.
