This paper assesses empirically the key drivers of private capital flows to a large sample of emerging market economies in the last decade. It analyzes the effect of the global financial cycle, measured by the VIX, on capital flows and investigates the role of fundamentals and country characteristics in mitigating or amplifying its effect. Using interaction models, we find the effect of the VIX to be non-linear. For low levels of the VIX, capital flows are driven by fundamental factors. During periods of stress, the VIX becomes the dominant driver of capital flows while other determinants, with the exception of interest rate differentials, lose statistical significance. Our results also suggest that the effect of global financial conditions on gross private capital flows increases with the host country’s level of financial sector development. Finally, our results imply that countries cannot fully insulate themselves from global financial shocks, unless creating a fragmented global financial system.

This paper documents the evolution of gross and net capital flows to emerging market economies and surveys the large literature on the potential drivers. While the capital flow landscape has been shaped by the evolution of both global and country-specific factors, the relative importance of these factors has varied over time and differs depending on the type of capital flows. The findings from the survey of the literature thus underscores the importance of policies in both source and recipient countries in shaping capital flows.

Has the unprecedented financial globalization of recent years changed the behavior of capital flows across countries? Using a newly constructed database of gross and net capital flows since 1980 for a sample of nearly 150 countries, this paper finds that private capital flows are typically volatile for all countries, advanced or emerging, across all points in time. This holds true across most types of flows, including bank, portfolio debt, and equity flows. Advanced economies enjoy a greater substitutability between types of inflows, and complementarity between gross inflows and outflows, than do emerging markets, which reduces the volatility of their total net inflows despite higher volatility of the components. Capital flows also exhibit low persistence, across all economies and across most types of flows. Inflows tend to rise temporarily when global financing conditions are relatively easy. These findings suggest that fickle capital flows are an unavoidable fact of life to which policymakers across all countries need to continue to manage and adapt.

Capital flow volatility is a concern for macroeconomic and financial stability. Nonetheless, literature is scarce in this topic. Our paper sheds light on this issue in two dimensions. First, using quarterly data for 65 countries over the period 1970Q1-2016Q1, we construct three measures of volatility, for total capital flows and key instruments. Second, we perform panel regressions to understand the determinants of volatility. The measures show that the volatility of all instruments is prone to bouts, rising sharply during global shocks like the taper tantrum episode. Capital flow volatility thus remains a challenge for policy makers. The regression results suggest that push factors can be more important than pull factors in explaining volatility, illustrating that the characteristics of volatility can be different from those of the flows levels.

Using a sample of 34 emerging markets and developing economies over the period 2009Q3-2015Q4, the paper employs a panel framework to study the determinants of capital flows, both net and gross, across a wide range of instruments. The baseline regressions are then extended to focus on high and low episodes – quarters with flows one standard deviation above/below mean. Overall, the results suggest that the capital flow slowdown witnessed in recent years is due to a combination of lower growth prospects of recipient countries and worse global risk sentiment. However, the determinants of flows can be considerably different across instruments and across the type of flows considered, net or gross. The sensitivity of certain types of flows, towards push and pull factors, increases during periods of high and low capital flows. Moreover, some variables may not necessarily be significant during normal times, but can be important drivers during such episodes, and vice versa. Indicators like the gap between the U.S. long- and short-term maturity bond yields – not significant during normal times – can be an important driver during high episodes.

This paper analyzes the behavior of gross capital inflows across 34 emerging markets (EMs). We first confirm that aggregate inflows to EMs co-move considerably. We then report three findings: (i) the aggregate co-movement conceals significant heterogeneity across asset types as only bank-related and portfolio bond and equity inflows do co-move; (ii) while global push factors in advanced economies mostly explain the common dynamics, their relative importance varies by type of flow; and (iii) the sensitivity to common dynamics varies significantly across borrower countries, with market structure characteristics (especially the composition of the foreign investor base and the level of liquidity) rather than borrower country’s institutional fundamentals strongly affecting sensitivities. Countries relying more on international funds and global banks are found to be more sensitive to push factors. Our findings suggest that EMs need to closely monitor their lenders and investors to assess their inflow exposures to global push factors.
