Where (FRED?) do I go to look at change in cash stores in bank savings/HYSA/MM accounts? Is this public?

As title states. Where can I go to look at the amount or rate of chance of cash in personal savings/MM/HYSA accounts? My assumption is that once we see a higher rate of change of money OUT of banks (negative roc or balance) then we will see a corresponding increase in the general market (follow the money). Where can I get this information, if available?
