Sovereign Risk, Currency Risk, and Corporate Balance Sheets

We provide a comprehensive account of the evolution of the currency composition of sovereign and corporate external borrowing by emerging markets over the past fifteen years. We show that a higher reliance on foreign currency debt by the corporate sector is associated with higher sovereign default risk. We introduce local currency sovereign debt and private sector currency mismatch into a standard sovereign debt model to examine how the currency composition of corporate borrowing affects the sovereign's incentive to inflate or default. A calibration of the model generates the empirical patterns of sovereign credit risk over the last decade.
