I think the person is most likely talking about minimum capital requirements (which are not a “deposit outside of their doors”) and doesn’t quite understand the system.
To understand the regulatory framework for banks, the best place to start is the BIS and Basel III. https://www.bis.org/committees/bcbs/standards Generally speaking, international banks follow Basel III in addition to their domestic regulators’ capital requirements (which are probably also derived from Basel III, but have differences just to make things tedious).
Not a bad place to start, yes.
However, BIS and Basel III (and the previous Basels) are just what's currently in force for most of the world. I suspect most people would be better served by more of an historical overview. But it also depends on what one is interested in.
