"Sell deficits, buy surpluses" was a winning strategy for emerging markets in 2013, but the new mantra for investing in developing economies may be "sell commodities, buy manufacturers", says Citi.
"It is unlikely that 'deficits vs surpluses' will always govern investor behavior towards emerging markets, especially now that this theme is becoming a little less relevant due to the current account adjustment that's taken place in some of the most vulnerable countries," Citi strategists led by Guillermo Mondino wrote in a report.
Countries with current account deficits such as Brazil, India, Indonesia, Turkey and South Africa – dubbed the Fragile Five - suffered for most of last year amid concerns over the Federal Reserve scaling back monetary stimulus, while those with current account surpluses including Korea, Hungary and Israel performed well.
Emerging market policymakers have since stepped up efforts to bring their deficits under control. However, their efforts have had varied success.
"Some of the disappointments in the Fragile Five adjustment process are explained by disappointing commodities markets," Mondino said, pointing to Indonesia, South Africa and Brazil.
"Meanwhile, India and Turkey – the two Fragile Five members with the largest manufactured exports sectors – seem to be having better luck adjusting their trade balances," he added.
In Indonesia, for example, the current-account gap widened slightly in the first quarter to 2.06 percent of gross domestic product (GDP), compared with 1.98 percent in the previous three months.
And Citi says weakening commodity exports will widen the current account gap further. It recently revised its 2014 current account deficit target for Indonesia to 2.8 percent of GDP from 2.5 percent.
Coal – the country's biggest mining export – for example, is declining not only in terms of volume but also value due to weak prices. During the first four months of the year, Indonesia's total coal exports totaled $7.4 billion, compared with $8.5 billion in the same period a year earlier, according to Societe Generale.
