It begins with a brief review of the debate from a historical point of view and then stresses the contemporary opposite's views on the fragility of financial system of emerging countries: the original sin and the debt intolerance hypothesis.

It criticizes the jurisdicional uncertainty proposition showing that an inherent flaw in the store of value of emerging market currencies, derived from original sin is the main reason for de facto inconvertibility and underdevelopment of domestic financial system of these countries.539556
