Foreign Exchange Intervention; A Shield Against Appreciation Winds?

This paper examines foreign exchange intervention practices and their effectiveness using a new qualitative and quantitative database for a panel of 15 economies covering 2004-10 with special focus on Latin America. Qualitatively, it examines institutional aspects such as declared motives, instruments employed, the use of rules versus discretion, and the degree of transparency. Quantitatively, it assesses the effectiveness of sterilized interventions in influencing the exchange rate using a two-stage IV-panel data approach to overcome endogeneity bias. Results suggest that interventions slow the pace of appreciation, but the effects decrease rapidly with the degree of capital account openness. At the same time, interventions are more effective in the context of already ‘overvalued’ exchange rates.

Can Foreign Exchange Intervention Stem Exchange Rate Pressures from Global Capital Flow Shocks

Many emerging market economies have relied on foreign exchange intervention (FXI) in response to gross capital inflows. In this paper, we study whether FXI has been an effective tool to dampen the effects of these inflows on the exchange rate. To deal with endogeneity issues, we look at the response of different countries to plausibly exogenous gross inflows, and explore the cross country variation of FXI and exchange rate responses. Consistent with the portfolio balance channel, we find that larger FXI leads to less exchange rate appreciation in response to gross inflows.

Riding Global Financial Waves: The Economic Impact of Global Financial Shocks on Emerging Market Economies

Over the past two decades, most emerging market economies witnessed two key developments. A marked process of financial integration with the rest of the world, arguably turning these economies more vulnerable to global financial shocks; and an improvement of macroeconomic fundamentals, helping to increase their resiliency to these shocks. Against a backdrop of these opposing forces, are these economies more vulnerable to global financial shocks today than in the past? Have better fundamentals offset increasing financial integration? If so, what fundamentals matter most? We address these questions by examining the role of these two forces over the past two decades in amplifying or buffering the economic impact of these shocks. Our findings show that EMEs, with the exception of Emerging Europe, have become less vulnerable. Exchange rate flexibility and external sustainability are key determinants of the impact of these shocks, while the extent to which deeper financial integration is a source of vulnerability depends on the exchange rate regime.

Unveiling the Effects of Foreign Exchange Intervention: A Panel Approach

We study the effect of foreign exchange intervention on the exchange rate relying on an instrumental-variables panel approach. We find robust evidence that intervention affects the level of the exchange rate in an economically meaningful way. A purchase of foreign currency of 1 percentage point of GDP causes a depreciation of the nominal and real exchange rates in the ranges of [1.7-2.0] percent and [1.4-1.7] percent respectively. The effects are found to be quite persistent. The paper also explores possible asymmetric effects, and whether effectiveness depends on the depth of domestic financial markets.

External Conditions and Debt Sustainability in Latin America

Highly favorable external conditions have helped Latin America strengthen its economic fundamentals over the last decade. But, has the region built enough buffers to guard itself from a weakening of the external environment? This paper addresses this question by developing a simple framework that integrates econometric estimates of the effect of global factors on key domestic variables that determine public and external debt dynamics, with the IMF‘s standard debt sustainability framework. Results suggest that, while some countries in the region are well placed to withstand moderate or even large shocks, many would benefit from having stronger buffers to be in a position to deploy countercyclical policies, especially under tail events. External sustainability, on the other hand, does not appear to be a source of concern for most countries.

Modernizing Bank Regulation in Support of Financial Deepening: The Case of Uruguay

This paper studies how Uruguays regulatory framework was gradually strengthened to address shortcomings identified during the 2002-03 crisis, to align with international standards and, more recently, to deal with cyclical pressures resulting in an acceleration of bank lending. In particular, regulatory reforms pertaining to loan classification and provisioning as well as liquidity requirements are reviewed and evaluated against best practices. The paper concludes that prudential regulation in Uruguay now generally conforms to high standards while also embracing innovative elements such as dynamic provisioning.

The Cost of Foreign Exchange Intervention: Concepts and Measurement

The accumulation of large foreign asset positions by many central banks through sustained foreign exchange (FX) intervention has raised questions about its associated fiscal costs. This paper clarifies conceptual issues regarding how to measure these costs both from an ex-post and an ex-ante (relevant for decision making) perspective, and estimates both marginal and total costs for 73 countries over the period 2002-13. We find ex-ante marginal costs for the median emerging market economy (EME) in the inter-quartile range of 2-5.5 percent per year; while ex-ante total costs (of sustaining FX positions) in the range of 0.2-0.7 percent of GDP per year for light interveners and 0.3-1.2 percent of GDP per year for heavy interveners. These estimates indicate that fiscal costs of sustained FX intervention (via expanding central bank balance sheets) are not negligible.

Foreign Exchange Intervention Under Policy Uncertainty

We study the use of foreign exchange (FX) intervention as an additional policy instrument in an environment with learning, where agents infer the central bank policy rules from its policy actions. Under full information, a central bank focused on stabilizing output and inflation can achieve better outcomes by using FX intervention as an additional policy tool. Under policy uncertainty, where agents perceive that monetary policy may also have exchange rate stabilization goals, the use of FX intervention entails a trade-off, reducing output volatility while increasing inflation volatility. While having an additional policy tool is always beneficial, we find that the optimal magnitude of intervention is higher in monetary policy regimes with lower uncertainty. These results indicate that the benefits of using FX intervention as an additional stabilization tool are greater in regimes where monetary policy is credibly focused on output and inflation stabilization.

Latin America : New Challenges to Growth and Stability

Over the past fifteen years countries in Latin America made tremendous progress in strengthening their economies and improving living standards. Although output fell temporarily during the global financial crisis, most economies staged a rapid recovery. However, economic activity across the region has been cooling off and the region is facing a more challenging period ahead. This book argues that Latin America can rise to the challenge, and policymakers in the region are already implementing reforms in education, energy, and other sectors. More is needed, and more is possible, in Latin Americas quest to continue to improve living standards.

Terms-of-Trade Cycles and External Adjustment

We study the process of external adjustment to large terms-of-trade level shifts—identified with a Markov-switching approach—for a large set of countries during the period 1960–2015. We find that adjustment to these shocks is relatively fast. Current accounts experience, on average, a contemporaneous variation of only about ½ of the magnitude of the price shock—indicating a significant volume offset—and a full adjustment within 3–4 years. Dynamics are largely symmetric for terms-of-trade booms and busts, as well as for advanced and emerging market economies. External adjustment is driven primarily by offsetting shifts in domestic demand, as opposed to variations in output (also reflected in the response of import rather than export volumes), indicating a strong income channel at play. Exchange rate flexibility appears to have played an important buffering role during booms, but less so during busts; while international reserve holdings have been a key tool for smoothing the adjustment process.
