National debts incurred by illegitimate regimes against the best interests of the citizens is a serious problem of international economics and politics. These sovereign debts, often referred to as odious debts, deplete the public purse and create an ongoing financial liability that serves to constrain investment and economic growth, and conspires to keep millions in poverty. This important and timely book explains the legal principles and politics involved in the issue of odious debts, and sovereign debt arrangements more generally. The author goes beyond abstract arguments and proposes legal rules and international regulation that should be put in place to create the right incentives to stop the transmission of odious debts. Her proposal is for a registration scheme for sovereign debt, and the imposition of positive duties on financiers who provide loans to sovereign borrowers. Sovereign Finance and the Poverty of Nations will appeal to students, academics, debt activists, policymakers, international finance practitioners and anyone with a general interest in sovereign finance affairs.
