Over the last six months, many developing emerging market economies had witnessed large, unforeseen, and unpredictable swings in their exchange rates. With rumors, and counter-rumors of likely tapering of the U.S. Federal Reserve’s Quantitative Easing (QE) programme, such swings resulted in abrupt depreciations by 16.7% in Indonesia, 7.3% in Thailand, 10.4% in Turkey, 9.3% in Brazil, 13.4% in India, and 8.8% in South Africa…
A recent policy brief by the Peterson Institute for International Economics provided Estimates of Fundamental Equilibrium Exchange Rates and revealed that many of these depreciations were, in fact, overshooting the fundamental equilibrium exchange rates that are consistent with the current account balances of these economies. Now it is found that Indonesia needs its currency to appreciate by 3.9%; Thailand, by 2.4%; the Philippines, by 3.8%; Malaysia, by 4.3%. Meanwhile, Turkey has to let its currency depreciate by 18.1%; South Africa, by 6.8%; Poland, by 4%; Brazil, by 3.4%. Table 1 below summarizes the relevant data.
