The international processes that are followed to resolve sovereign debt crises - generally referred to as 'sovereign debt management' (SDM) - might affect the enjoyment of internationally recognized socio-economic rights (ESR) by persons who live in debtor countries. Against this backdrop, this project examines and aims to clarify the international ESR obligations of the main actors that engage in SDM processes, namely: i) the indebted state; ii) third states that act as bilateral or multilateral lenders; and iii) international financial institutions. Initially, the study distinguishes between two 'actor-based' types of SDM processes, identifies the forms of conduct of the involved actors and the categories of the applicable conditionalities, and explains how the latter can negatively affect ESR enjoyment within a debtor country. In turn, the thesis investigates the existence, scope and meaning of each actor's international ESR duties, and addresses jurisdictional matters that emerge in that regard. Lastly, the project explores the benefits of adopting an ESR-approach to SDM, and offers insights on how the ESR duties of each actor can be better operationalized in SDM contexts.
