The dollar and yen exchange traded funds (ETFs) are gearing up to cap off a banner month, with their strongest one-month gain against the euro ever.

Global recession fears are prompting investors to sell off their higher-yielding currencies, benefiting the dollar and yen, report Lukanyo Mnyanda and Stanley White.

In October alone, CurrencyShares Japanese Yen (FXY) is up 7.8% and PowerShares DB U.S. Dollar Index Bullish (UUP) is up 6.8%. Year-to-date, they’re up 12.9% and 10.2%, respectively.

A strong yen, however, isn’t always a good thing for everyone. Since Japan is such a big exporter of goods, a robust yen hurts profits, which will then hurt the country’s stock market. That, in turn, could have a ripple effect on exchanges in the United States and Europe.
