In round terms, this official counterfeiting spree amounted to $3.5 trillion— reflecting the difference between the Fed's approximate $900 billion balance sheet when its "extraordinary policies" incepted at the time of the Lehman crisis and its $4.4 trillion of footings today. That's a lot of something for nothing. It's a grotesque amount of fraud.
The scam embedded in this monumental balance sheet expansion involved nothing so arcane as the circuitous manner by which new central bank reserves supplied to the banking system impact the private credit creation process. As is now evident, new credits issued by the Fed can result in the expansion of private credit to the extent that the money multiplier is operating or simply generate excess reserves which cycle back to the New York Fed if, as in the present instance, it is not.
But the fact that the new reserves generated during QE have cycled back to the Fed does not mitigate the fraud. The latter consists of the very act of buying these trillions of treasuries and GSE securities in the first place with fiat credits manufactured by the central bank. When the Fed does QE, its open market desk buys treasury notes and, in exchange, it simply deposits in dealer bank accounts new credits made out of thin air. As it happened, about $3.5 trillion of such fiat credits were conjured from nothing during the last 72 months.
