On September 23, it cost $1.47 to buy a euro, but today you can get one for just $1.37. The value of Iceland's króna plunged after news of a possible national bankruptcy: After trying to peg the exchange rate to the euro, the government gave up the effort and asked the IMF for help.
The situation is still in flux, but what's certain is that a dollar only bought 75 króna three months ago; a buck will buy at least 110 today, if you can find a bank that still has any cash! (Trading in the currency is effectively frozen right now.)
England, too, is getting a bit cheaper, with the pound down more than 10 percent against the dollar over the past three months. Even bank-happy Switzerland's franc is off, down 9 percent compared to July.
