A MULTISTAGE DECISION MODEL FOR THE OPTIMAL ISSUANCE OF SOVEREIGN DEBT UNDER ESA95
2014
The aim of this paper is to develop a stochastic programming model for the optimal composition of debt portfolios. Such a prob- lem has recently acquired a more and more major interest, being the indebtedness of many countries quite worrying. We propose a stochastic programming model where the decision maker desires to minimize a certain cost function while bounding the interest rate risk. Our analysis focus mainly on the cost function ESA95, which is a methodology developed by the European System of Accounts to gauge the cost of servicing the debt. The model is implemented under two financing strategies, one as- sumes the government cannot resort to budget surplus to pay interest expenses,…
Contingent Convertible Bonds for Sovereign Debt Risk Management
2018
Abstract We consider convertible bonds that contractually stipulate payment standstill, contingent on a market indicator of a sovereign’s credit worthiness breaching a distress threshold. This financial innovation limits ex ante the likelihood of debt crises and imposes ex post risk sharing between creditors and the debtor. Drawing from literature on contingent contracts, neglected risks, and bank CoCo, we extend prevailing arguments in favor of sovereign CoCo (S-CoCo). We discuss issues relating to their design: which market trigger, market discipline and sovereign incentives, and errors of false alarms or missed crises, and provide supporting evidence with eurozone data and a simple simul…
