We study the optimal management of capital flows in a small open economy model with financial frictions and multiple policy instruments. The paper reports two main findings. First, both foreign exchange intervention (FXI) and macroprudential polices are tools complementary to the monetary policy rate that can largely reduce inflation and output volatility in a scenario of capital outflows. Second, the optimal policy mix depends on the underlying shock driving capital flows. FXI takes the leading role in response to foreign interest rate shocks, while macroprudential policy becomes the prominent tool for domestic risk shocks. These results highlight the importance of calibrating the use of multiple instruments according to the underlying shocks that induce shifts in capital flows.

The volatility of capital flows to emerging markets continues to pose challenges to policymakers. In this paper, we propose a new framework to answer critical policy questions: What policies and policy frameworks are most effective in dampening sharp capital flow movements in response to global shocks? What are the near- versus medium-term trade-offs of different policies? We tackle these questions using a quantile regression framework to predict the entire future probability distribution of capital flows to emerging markets, based on current domestic structural characteristics, policies, and global financial conditions. This new approach allows policymakers to quantify capital flows risks and evaluate policy tools to mitigate them, thus building the foundation of a risk management framework for capital flows.

Policymakers have relied on a wide range of policy tools to cope with capital flow shocks. And yet, the effects and interaction of these policies remain under debate, as does the motivation for using them. In this paper, quantile local projections are used to estimate the entire distribution of future policy responses to portfolio flow shocks for 20 emerging markets and understand the variety of policy choices across the sample. To assuage endogeneity concerns, estimates rely on the fact that global capital flows are exogenous from the viewpoint of any one of these countries. The paper finds that: (i) policy responses to capital flow shocks are heterogeneous across countries, fat-tailed—“extreme” responses tend to be more elastic than “typical” responses—and asymmetric—“extreme” responses tend to be more elastic with respect to outflows than to inflows; (ii) country characteristics are linked to policy choices—with cross-country differences in forex intervention relating to the size of balance sheet vulnerabilities and the depth of the forex market; (iii) the use of targeted macroprudential policy and capital flows management measures can help “free the hands” of monetary policy by allowing it to focus more squarely on domestic cyclical developments.

This paper uses a general equilibrium model to examine the central role played by commercial banks in intermediating and amplifying the capital flow shocks to the local economy in the 1997 Asia financial crisis. It finds that a sudden stop of capital inflows affects the equilibrium credit supply through two channels: first, the plunge of foreign financing decreases the loanable funds directly; and second the sudden stop drives up the cost of providing banking services, thereby additionally reducing the available bank credit to firms through a "deposit run". Empirical results from a VAR model broadly support the theoretical implications.

During the 2008 global financial crisis, several emerging market economy (EME) authorities argued that advanced economy policies including large-scale asset purchases by the U.S. Federal Reserve were primary sources of excessive capital flows and created adverse spillover effects to the EMEs. More recently, EME policy makers have been concerned about the adverse effects of advanced economy monetary policy normalization. Tracking the link between the monetary policy shocks in advanced countries and capital flows to emerging markets can be crucial for informing the debate about appropriate policy responses to capital inflows by the EMEs.
