The bankruptcy of the United States is now certain

Excerpt:

When governments go bankrupt it's called "a default." Currency speculators figured out how to accurately predict when a country would default. Two well-known economists - Alan Greenspan and Pablo Guidotti - published the secret formula in a 1999 academic paper. That's why the formula is called the Greenspan-Guidotti rule. The rule states: To avoid a default, countries should maintain hard currency reserves equal to at least 100% of their short-term foreign debt maturities. The world's largest money management firm, PIMCO, explains the rule this way: "The minimum benchmark of reserves equal to at least 100% of short-term external debt is known as the Greenspan-Guidotti rule. Greenspan-Guidotti is perhaps the single concept of reserve adequacy that has the most adherents and empirical support."

So how does America rank on the Greenspan-Guidotti scale? It's a guaranteed default.
