If your money was denominated in yen or Australian dollars, you would have been in luck this year. Among the major currencies, the yen was the best performing against the US dollar, up 12%. The yen also rose 19% against the euro in 2010.
In addition, the Australian dollar has appreciated 13% versus the US dollar, and is up 18.6% against the euro this year, mostly off strength from increased economic interaction with China. The Swiss franc was the third strongest currency this year, up 16% against the euro.
