When a bond's trading price drops to half its face value, it's a sign of significant trouble. .
Recently, 30-year #US Treasuries issued during the pandemic fell below 50 cents on the dollar.
In any other country this would mean bankruptcy, but when the rating agencies like Standard & Poor's, Moody's and Fitch, an incredibly powerful oligopoly, arbitrarily rating, uncontrollably rating and ruling the global financial system in an absolute fashion, for the US it s OK.
Not for long, tho
