Foreign exchange intervention (FXI) is a highly debated topic. Yet, comprehensive and comparable data on FXI is hard to find. This paper provides a new dataset of FXI covering a large number of countries over the period 2000-20 at monthly and quarterly frequencies. It includes publicly available data for about 40 countries and carefully constructed proxies for 122 countries. Proxies are focused on both spot and derivative transactions that alter the central bank’s foreign currency position and account for a wide range of central bank operations, including vis-à-vis residents, the first proxy to do so to our knowledge. The paper discusses the merits of the new proxy relative to coarser measures traditionally used like the change in reserves, and potential definitional differences with published data. The paper also presents stylized facts using our newly constructed FXI proxies.

The paper documents the use of foreign exchange intervention (FXI) across countries and monetary regimes, with special attention to its use under inflation targeting (IT). We find significant differences between advanced and emerging market economies, with the former group conducting FXI limitedly and broadly symmetrically, while the use of this policy instrument in emerging market countries is pervasive and mostly asymmetric (biased towards purchasing foreign currency, even after taking into account precautionary motives). Within emerging markets, the use of FXI is common both under IT and non-IT regimes. We find no evidence of FXI being used in response to inflation developments, while there is strong evidence that FXI responds to exchange rates, indicating that IT central banks in EMDEs have dual inflation/exchange rate objectives. We also find a higher propensity to overshoot inflation targets in emerging market economies where FXI is more pervasive.

I conduct interviews with 32 Central Bankers from Emerging Markets and present five unifying themes that explain their behavior when reacting to a U.S. monetary tightening. I then estimate the impulse response functions of their two main monetary tools, the policy rate and foreign exchange interventions, to an increase in the U.S. rate, using the answers from the interviews as a guide for the best econometric specification. I find that most Central Banks react to a U.S. tightening by raising domestic rates, regardless of the exchange rate regime, but their reasons for doing so vary – from controlling inflation to preventing capital outflows.

This study looks into the significance of a floating exchange rate regime, further development of the foreign exchange derivatives market, and concurrent internationalization of the Renminbi (RMB) for a resilient, open, and growing Chinese economy. The first chapter analyzes the macroeconomic impact of foreign exchange intervention based on empirical studies on 26 economies, explaining why most countries favor a floating exchange rate regime under the existing international monetary system. The second chapter discusses the macroeconomic and microeconomic conditions that would facilitate a successful transition to a floating exchange rate. The final two chapters discuss the importance of further developing the foreign exchange derivatives market in China and explores paths toward further opening-up of the capital market and internationalization of the RMB under a floating exchange rate. Based on the authors’ decades of reflections and systematic analysis on real cases both in China and abroad, the title sheds lights on China’s exchange rate issues and research on exchange rate policy. This book will be an essential reference for scholars, students, professionals, and policymakers interested in exchange rate, currency internationalization, the financial market, especially the derivatives market, and the Chinese economy.

We estimate a New Keynesian small open economy model which allows for foreign exchange (FX) market frictions and a potential role for FX interventions for a large set of emerging market economies (EMEs) and some inflation targeting (IT) advanced economy (AE) countries serving as a control group. Next, we use the estimated model to examine the empirical support for the view that interest rate policy may not be sufficient to stabilize output and inflation following capital outflow shocks, and the extent to which FX interventions (FXI) can improve policy tradeoffs. Our results reveal significant structural differences between AEs and EMEs—in particular FX market depth—leading to different transmission of capital outflow shocks which justifies occasional use of FXI in some EMEs in certain situations. Our analysis also highlights the critical importance of accounting for the endogeneity of FXI behavior when assessing FX market depth and policy tradeoffs associated with volatile capital flows in past episodes.

This paper examines the impact of Dollar exchange rate volatility on firm productivity in Emerging Markets economies (EMs). Using firm level data covering 16 EMs over the period 1998 -2019, the paper shows that dollar exchange rate volatility reduces firm productivity growth. Exploring channels, its finds that the results are driven by countries with low level of financial development, high dollar invoicing, high bilateral trade with the US, high collective bargaining coverage and open capital account. Exploring the role of policy, it finds that Foreign Exchange Interventions (FXI) dampen this impact on firm productivty. Further, exploiting firm level data, the paper shows that dollar exchange rate volatility operates also through the financial friction channel, reducing contemporaneous investments, especially at firms with low liquidity buffers and weak balance sheet (high leverage). The role of financial frictions is confirmed through the finding that younger firms, more likely to face financial constraints, are also found to be more vulnerable to dollar exchange rate volatility. In addition, we also find evidence of a large and persistent effect on firms with highly irreversible investment, lending support for the real option channel of uncertainty on the dollar exchange rate. These findings are robust to a battery of tests, including controlling for uncertainty, financial crises and using an instrumental variable strategy exploiting US monetary policy shocks as an exogenous source of variation in dollar exchange rate volatility.
