Taper Tantrum (2013)
May-September 2013What Happened
Federal Reserve Chair Ben Bernanke mentioned the possibility of tapering quantitative easing during congressional testimony in May 2013. Emerging-market portfolio inflows, which had surged from $192 billion to $598 billion quarterly during the era of easy money, reversed sharply. Brazil, India, Indonesia, Turkey, and South Africa — dubbed the "Fragile Five" — saw currencies depreciate by as much as 15 percent in four months.
Outcome
Central banks in affected countries burned through foreign reserves defending currencies and were forced to raise interest rates despite weak domestic growth.
The episode established that portfolio investors in emerging markets act as a herd. It prompted several countries to build larger reserve buffers and shift toward local-currency borrowing — exactly the resilience measures the IMF is now urging more broadly.
Why It's Relevant Today
The Taper Tantrum occurred when non-bank investors supplied a smaller share of emerging-market debt than they do today. The IMF's 2026 warning is essentially that the same dynamic exists at much larger scale, with non-bank investors now supplying 80 percent of flows versus a lower share in 2013.
