An Alternative Framework For Foreign Exchange Risk Management Of Sovereign Debt

Abstract: This paper proposes a measure of synchronization in the movements of relevant domestic and foreign fundamentals for choosing suitable currency for denomination of foreign debt. The selection of explanatory variables for exchange rate volatility is motivated using a New Keynesian Policy model. The model predicts that not only traditional optimal currency area variables, but also variables considered by the literature on currency preferences, such as money velocity, should be relevant for explaining exchange rate volatility. The findings show that measures of inflation synchronization, money velocity synchronization, and interest rate synchronization can be useful indicators for decisions on the currency denomination of foreign debt.

This volume, edited by David Folkerts-Landau and Marcel Cassard, consists of papers presented at a conference held in Hong Kong SAR that was hosted by the IMF and the Hong Kong Monetary Authority. It focuses on a wide range of issues confronting policymakers in managing their sovereign assets and liabilities in a world of mobile capital and integrated capital markets. Topics include public debt management strategy, central bank reserves management, technical and quantitive aspects of risk management, and credit costs and borrowing capacity in optimizing debt management. The papers draw on experiences of policymakers and private sector participants actively involved in formulating and implementing debt and reserves policy.

In an environment of sizable and volatile capital flows and integrated international capital markets, large and unhedged net external sovereign liabilities expose countries to swings in international asset prices and to potential speculative currency attacks. The paper argues that an essential step in reducing emerging market vulnerability to such external shocks is to reform the institutional arrangements governing asset and liability management policies, so as to promote a transparent, publicly accountable, and professional incentive structure.

The Asian Development Bank (ADB) has been working closely with the Association of Southeast Asian Nations (ASEAN) and the People's Republic of China, Japan, and the Republic of Korea---collectively known as ASEAN+3---to foster the development of local currency bond markets and facilitate regional bond market integration under the Asian Bond Markets Initiative (ABMI). ABMI was launched in 2002 to strengthen the resilience of the region's financial system by developing local currency bond markets as an alternative source to foreign currency denominated short-term bank loans for long-term investment. Bond investors typically have a long position in local currency bond markets. To manage their foreign exchange (FX) risk, they may want to hedge that exposure for a period of time. They also want to be sure they can easily convert the local currency to dollars upon the sale of a bond. This study was undertaken under ABMI and funded by the Government of Japan. It reviews the FX and FX hedging markets in ASEAN+3 as they relate to cross-border investments in local currency bonds, and makes recommendations to facilitate the development of the markets and FX risk management.

This paper provides an overview of sovereign debt portfolio risks and discusses various liability management operations (LMOs) and instruments used by public debt managers to mitigate these risks. Debt management strategies analyzed in the context of helping reach debt portfolio targets and attain desired portfolio structures. Also, the paper outlines how LMOs could be integrated into a debt management strategy and serve as policy tools to reduce potential debt portfolio vulnerabilities. Further, the paper presents operational issues faced by debt managers, including the need to develop a risk management framework, interactions of debt management with fiscal policy, monetary policy, and financial stability, as well as efficient government bond markets.

This paper reviews empirical and theoretical work on the links between banks and their governments (the bank-sovereign nexus). How significant is this nexus? What do we know about it? To what extent is it a source of concern? What is the role of policy intervention? The paper concludes with a review of recent policy proposals.
