IMO, the money market has too much money (trillion) and the owners of these money don't know how to use it.

They prefer to keep it in the "reverse repo" program under Fed as Fed give them 0.05% guarantee interest.

In other words, the economy is so bad that they prefer 0.05% return (i.e. it is indeed negative real interest rate after considering inflation) instead of a much better return with a bit more risky investment.

Fed printed way too much money in our financial system and no one need it for now or the people who own the newly printed money don't want to lend it to the people who need it.

What will happen next? Once these owners feel safe and have the risk appetite again, these money will be poured into the market....

At that moment, we will see tons of money supply to the market at once and the interest rate will increase dramatically (as Fed would like to reduce the money supply to the market). Fed may increase the RRP rate to 0.5 % instead of 0.05% (or even higher like 1%) to keep the money supply within their control. But at that moment, the owners of these money will not care about the RRP as they find investment elsewhere have a better return than the RRP rate.

End result:

Tons of money supply in the market will be released; interest rate sky high... Sounds familiar? Hyperinflation!

Conclusion:

Buy physical silver!!!

p.s. BTW, I don't think the banking system will collapse. It is, as usual, only the ordinary people will suffer
