2013 seems like a long time ago but worth revisiting this (4 minute) memo from Reuters about the purpose of the Reverse Repo Facility (now over $2.3tril) and explains what your current MMKT Mutual Fund is currently comprised of.

“In an overnight reverse repo transaction, the Fed would sell a Treasury bond to a U.S. primary dealer or a large money market fund and buy it back the next day for a slightly higher price. The transaction temporarily takes cash out of the banking system, while the dealer or fund earns interest on the deal.”

So basically as I understand it – while you should be earning say 2% APR on your MMKT holdings in (today’s) rising rate environment, you are actually only earning say .75% while the gov’t gives (kicks back) the mutual fund .75% and the remaining .5% is ‘disappeared’ from the system (QT).

There is also the possibility the RRP could suddenly stop (on the Fed side) at say the depths of a depression, and when maximum paper is held in MMKT’s – they then (to save the system of course) replace those $’s with FedCoin or some other form of CBDC.  Just sharing some thoughts on possible outcomes for this $#!t$#0w.

Seriously Tenters, take a look at the composition of what your MMKT Mutual funds holdings are.
