Resolution Criteria: 

This question will be resolved as "Yes" for any given country if credible financial news sources or international financial institutions (such as the IMF, World Bank, or major credit rating agencies) report that the country’s government has entered a form of sovereign default, such as by missing a payment on external debt obligations and not making the payment within an applicable grace period, or announcing a moratorium on external debt payments. A default will be considered to have occurred at the earliest instance reported by a major financial news source or institution.

For the purpose of this question, "external debt" refers to debt issued under foreign jurisdictions or denominated in foreign currencies. Temporary payment delays due to technical issues that are quickly resolved will not be considered defaults.
