Foreign Exchange Intervention Rules for Central Banks: A Risk-based Framework


Book Description

This paper presents a rule for foreign exchange interventions (FXI), designed to preserve financial stability in floating exchange rate arrangements. The FXI rule addresses a market failure: the absence of hedging solution for tail exchange rate risk in the market (i.e. high volatility). Market impairment or overshoot of exchange rate between two equilibria could generate high volatility and threaten financial stability due to unhedged exposure to exchange rate risk in the economy. The rule uses the concept of Value at Risk (VaR) to define FXI triggers. While it provides to the market a hedge against tail risk, the rule allows the exchange rate to smoothly adjust to new equilibria. In addition, the rule is budget neutral over the medium term, encourages a prudent risk management in the market, and is more resilient to speculative attacks than other rules, such as fixed-volatility rules. The empirical methodology is backtested on Banco Mexico’s FXIs data between 2008 and 2016.
















Regional Monetary Integration


Book Description

This book surveys the prospects for regional monetary integration in various parts of the world. Beginning with a brief review of the theory of optimal currency areas, it goes on to examine the structure and functioning of the European Monetary Union, then turns to the prospects for monetary integration elsewhere in the world - North America, South America, and East Asia. Such cooperation may take the form of full-fledged monetary unions or looser forms of monetary cooperation. The book emphasizes the economic and institutional requirements for successful monetary integration, including the need for a single central bank in the case of a full-fledged monetary union, and the corresponding need for multinational institutions to safeguard its independence and assure its accountability. The book concludes with a chapter on the implications of monetary integration for the United States and the US dollar.




Monetary and Currency Policy Management in Asia


Book Description

Asian economies strengthened their monetary and currency management after the Asian financial crisis of 19971998, and came through the global financial crisis of 20072009 relatively well. Nevertheless, the recent global crisis has presented new challenges. This book develops recommendations for monetary and currency policy in Asian economies aimed at promoting macroeconomic and financial stability in an environment of global economic shocks and volatile capital flows. Monetary and Currency Policy Management in Asia draws lessons from crises and makes concrete macroeconomic policy recommendations aimed at minimizing the impacts of an economic and financial downturn, and setting the stage for an early return to sustainable growth. The focus is on short-term measures related to the cycle. The three main areas addressed are: monetary policy measures, both conventional and unconventional, to achieve both macroeconomic and financial stability; exchange rate policy and foreign exchange reserve management, including the potential for regional cooperation to stabilize currency movements; and ways to ease the constraints on policy resulting from the so-called 'impossible trinity' of fixed exchange rates, open capital accounts and independent monetary policy. This is one of the first books since the global financial crisis to specifically and comprehensively address the implications of the crisis for monetary and currency policy in emerging market economies, especially in Asia. Presenting a broad menu of policy options for financial reform and regulation, the book will be of great interest to finance experts and policymakers in the region as well as academics and researchers of financial and Asian economics as well as economic development.




The Relative Effectiveness of Spot and Derivatives Based Intervention


Book Description

This paper studies the relative effectiveness of foreign exchange intervention in spot and derivatives markets. We make use of Brazilian data where spot and non-deliverable futures based intervention have been used in tandem for more than a decade. The analysis finds evidence in favor of a significant link between both modes of intervention and the first two moments of the real/dollar exchange rate. As predicted by theory for the case of negligible convertibility risk, the impact of spot market intervention in our baseline sample is strikingly similar to that achieved through futures based intervention worth an equivalent amount in notional principal.
