You are a corporate treasurer for Esso Oil. The quoted rate on dollar denominated euro commercial paper has just blipped down recently. Your firm can issue $10 million of 180-day euro commercial paper in the London markets at 3.45%. You can also invest the proceeds in the United States in comparable maturity negotiable dollar-denominated CDs, which are quoting 3.95%. Ignoring any transactions costs, how much money, if any, can Esso make by borrowing in the euro markets and investing in the United States? Is this a good deal or not? Should you expect it to last? Explain.
