Sovereign default

When a sovereign entity fails to pay its debts

A sovereign default is the failure or refusal of the government of a sovereign state to pay back its debt in full when due. Cessation of due payments may either be accompanied by that government's formal declaration that it will not pay its debts (repudiation), or it may be unannounced. A credit rating agency will take into account in its gradings capital, interest, extraneous and procedural defaults, and failures to abide by the terms of bonds or other debt instruments.
