Based on a dataset of 112 emerging economies and developing countries, this paper addresses two key questions regarding the accumulation of international reserves: first, has the accumulation of reserves effectively protected countries during the 2008-09 financial crisis? And second, what explains the pattern of reserve accumulation observed during and after the crisis? More specifically, the paper investigates the relation between international reserves and the existence of capital controls. We find that the level of reserves matters: countries with high reserves relative to short-term debt suffered less from the crisis, particularly if associated with a less open capital account. In the immediate aftermath of the crisis, countries that depleted foreign reserves during the crisis quickly rebuilt their stocks. This rapid rebuilding has, however, been followed by a deceleration in the pace of accumulation. The timing of this deceleration roughly coincides with the point when reserves reached their pre-crisis level and may be related to the fact that short-term debt accumulation has also decelerated in most countries over this period.

We explore the role of financial openness – capital account openness and gross capital inflows – and a newly constructed gravity‐based contagion index to assess the importance of these factors in the run‐up to currency crises. Using a quarterly data set of 46 advanced and emerging market economies (EMEs) during the period 1975Q1‐2011Q4, we estimate a multi‐variable probit model including in the post‐Lehman period. Our key findings are as follows. First, capital account openness is a robust indicator, reducing the probability of currency crisis for advanced economies, but less so for EMEs. Second, surges in gross (but not net) capital inflows in general increase the risk of a currency crisis, but looking at a disaggregated level, gross portfolio flows increase the risk of a currency crisis for advanced economies, whereas gross FDI inflows decrease the risk of a crisis for EMEs. Third, contagion has a very strong impact, consistent with the past literature, especially during the post‐ Lehman shock episode. Last, our model performs well out‐of‐sample, confirming that early warning models were helpful in judging relative vulnerability of countries during and since the Lehman crisis.

This paper revisits the bipolar prescription for exchange rate regime choice and asks two questions: are the poles of hard pegs and pure floats still safer than the middle? And where to draw the line between safe floats and risky intermediate regimes? Our findings, based on a sample of 50 EMEs over 1980-2011, show that macroeconomic and financial vulnerabilities are significantly greater under less flexible intermediate regimes—including hard pegs—as compared to floats. While not especially susceptible to banking or currency crises, hard pegs are significantly more prone to growth collapses, suggesting that the security of the hard end of the prescription is largely illusory. Intermediate regimes as a class are the most susceptible to crises, but “managed floats”—a subclass within such regimes—behave much more like pure floats, with significantly lower risks and fewer crises. “Managed floating,” however, is a nebulous concept; a characterization of more crisis prone regimes suggests no simple dividing line between safe floats and risky intermediate regimes.

• Christian Saborowski, Sarah Sanya, Hans Weisfeld and Juan Yepez. “Effectiveness of Capital Outflow Restrictions,” January 2014. IMF Working Paper no. 14/8. Washington, DC: International Monetary Fund.

This paper examines the effectiveness of capital outflow restrictions in a sample of 37 emerging market economies during the period 1995-2010, using a panel vector autoregression approach with interaction terms. Specifically, it examines whether a tightening of outflow restrictions helps reduce net capital outflows. We find that such tightening is effective if it is supported by strong macroeconomic fundamentals or good institutions, or if existing restrictions are already fairly comprehensive. When none of these three conditions is fulfilled, a tightening of restrictions fails to reduce net outflows as it provokes a sizeable decline in gross inflows, mainly driven by foreign investors.
