WSJ article "Yield hungry investors revive carry trade in emerging markets"

Expectations that rates in the developed world are unlikely to rise have made high-yielding emerging-market currencies more appealing

A cautious shift from the world's central banks is sending investors hunting for big paydays in emerging-market currencies, despite concerns that global growth may continue to slow.

Many are employing a strategy known as the carry trade, where an investor borrows in a low-yielding currency to roll the funds into a higher-yielding emerging-market asset, such as local bonds and pockets the difference. Emerging markets are popular targets for carry traders because they often offer yields that are much higher than those found in developed countries.
