Still think emerging markets are too risky? Think again. Smarter policies are leading to less vulnerable economies and rising currencies. For investors who need to wring more income from their bond portfolios, it’s time for a fresh look.

Just a few years ago, the outlook for emerging markets was very different. Many countries were on a borrowing binge, which resulted in large current account and fiscal deficits. That left them dependent on capricious portfolio inflows—money invested in domestic stock and bond markets or deposited in domestic banks—to finance their spending.

Foreigners were happy to fund those deficits for a while because they needed higher yields than developed-market bonds could deliver. But when the Federal Reserve hinted in 2013 that it would start to tighten its easy money policies, investors quickly cut their risk, and the flow of capital into these emerging economies dried up.

The result: emerging-market asset values plunged and economic growth stalled. The most vulnerable countries—Brazil, India, Indonesia, Turkey and South Africa—became known as “the fragile five” and were hit especially hard. By the first quarter of 2016, Brazil’s real had lost about half its value against the US dollar, while the Turkish lira was down 40%. Between 2013 and 2015, the J.P.

WEAK CURRENCIES DO THE HEAVY LIFTING

When it comes to wading back into emerging markets, investors may be wondering: Why now?

There’s no denying that the adjustment these countries went through was painful. But it’s finally starting to pay off in the form of stronger economic fundamentals. In other words, the fragile five aren’t so fragile anymore.
