If we look at the total in the federal reserves account
Here at the moment is about 3 trillion and if the reserve requirement is 10% does that mean that there is at least 30 trillion out there in money supply?
I know that there can be excess reserves, but give the fact that the reserves have increased dramatically in shot period of time, we can assume that there was a shortage and not excess of supply meaning the 3T were needed to back up around 30T.
You cannot infer wider money numbers from the monetary base, since there are excess reserves. Those excess reserves were not created to “back up” deposits, it was a deliberate action to expand the monetary base.
