You can go to a local U.S. Range Rover dealership this weekend and buy a nicely equipped Range Rover HSE for $85,000 or a Supercharged for over $100,000. If you finance it in U.S. dollars, at least you know what you owe. If you want to be as fancy as your new car, you can borrow in a foreign currency and pay it back with your local currency. Youโ€™ll be styling with the best of the hedge fund managers if your currency appreciates. But what happens if the bottom falls out?

Thatโ€™s exactly what happened in Iceland this decade. In his new book, Boomerang, Michael Lewis writes about what happens when a nation of fishermen turns into a nation of hedge fund managers. He explains how with their newfound expertise and with local interest rates running near 15.5% the Icelanders borrowed in yen or Swiss francs to buy Range Rovers. But when the Icelandic krona cratered, owners of Range Rovers financed at the equivalent of $35,000 suddenly owed $100,000. Visiting Iceland at the time, Lewis commented to a local about the unsettling explosions outside his hotel room. It turned out that those explosions were the solution to the Range Rover debt:

To the Range Rover problem there are two immediate solutions. One is to put it on a boat, ship it to Europe, and try to sell it for a currency that still has value. The other is set it on fire and collect the insurance: Boom!

Check out Michael Lewisโ€™s Boomerang for some more examples of the mistreatment of money.
