Mauro Roca, emerging markets currency strategist at Deutsche Bank, remarks that emerging market countries “are increasing the amount of capital controls and direct intervention in order to temper currency inflows and reduce the effect of these flows on currency appreciation,” writes Charles Wallace for Daily Finance.

It’s also a mistake to believe that all currencies are weak. CurrencyShares Swedish Krona (NYSEArca: FXS) and CurrencyShares Mexican Peso (NYSEArca: FXM) are actually two of the best-performing currency ETFs year-to-date.

There are also opportunities in high-yielding currencies, such as the CurrencyShares Australian Dollar (NYSEArca: FXA) and the WisdomTree Dreyfus Brazilian Real (NYSEArca: BZF).
