All of this has been manipulated by Federal Reserve games with rates and free money for banks etc. PRinting money that will never be paid. Over 200 trillion in the hole now and for future obligations. It only gets worse. ALl chasing yield and no value . Happens like last time Fed manipulated rates.Not a free market and that what causes these massive sell-off on reality.Worthless inflated paper dollars being printed to finance this massive debt. Wake up people.
