I always thought the Fed bought Treasuries (usually) from a Primary Dealer and credited their account at the Fed with newly created money. I await your explanation of how it really works.
It is this little “only” thing. I realize you have been asleep for the past few months, but not to long ago the FED came up with a couple of new ways to inject liquidity in a total dosage of around $500 B -in round numbers - since the beginning of the BSC debacle which everyone besides you calls a bailout. Go to their website and you can read about it.
