High-quality public debt management plays a critical role in reducing the vulnerability of developing countries to financial crises. With sound risk and cash management, effective coordination with fiscal and monetary policy, good governance, and adequate institutional and staff capacity in place, governments can develop and implement effective medium-term debt management strategies.Managing Public Debt: From Diagnostics to Reform Implementation draws insights from a joint pilot program set up by the World Bank and International Monetary Fund to design relevant reform and capacity-building programs in twelve countries. The experiences of these geographically and economically diverse countries—Bulgaria, Colombia, Costa Rica, Croatia, Indonesia, Kenya, Lebanon, Nicaragua, Pakistan, Sri Lanka, Tunisia, and Zambia—illustrate the challenges and elements necessary to make progress in the area of public debt management.
