Capital Flows During Quantitative Easing: Experiences of Developing Countries

A potentially important side effect of quantitative easing (QE) by the United States Federal Reserve was the expansion of capital flows into developing countries. As a result, there were widespread concerns that reversing QE might trigger financial instability in those countries. The central objective of our article is to empirically investigate this important issue by (1) examining the effect of QE on capital flows into developing Asia and (2) identifying the most significant factors that influence the effect of a QE taper tantrum on exchange rate instability. We find that capital flows into developing countries during QE were at least comparable to those before the global financial crisis. We also find that capital flows during QE and the symptoms of those capital flows such as high inflation, credit expansion, and the deterioration of the current-account balance accounted for much of the destabilizing effect of a QE taper tantrum. While there is no evidence that macroprudential policies directly reduce the destabilizing effect, they can nevertheless be useful preemptive measures.
