What is a banker's bank? I came across this term when I was scrolling through my research on banks. I came across this definition, that says that they are banks that service the charter banks that founded them(or so I understood). I didn't know what charter was so I founded this, which says charter is a legal document rather that a type of bank. The central bank(of my country), says it is a banker's bank that is supposed to actually regulate other bank's monetary policies. So, I was getting very confused with my amateur deductions and finally resolved here.
