The Federal Reserve system of banks and other US intragovernmental holdings account for a stunning $5.127 trillion in US Treasury debt. This is the most recent number available (Sept 2009), and is at an all-time high, rising in every reporting period since 2007. About a decade ago, the total government holdings were “only” $2.5 trillion.
