what is a banker&#39;s bank?
<p>What is a banker's bank? I came across this term when I was scrolling through my research on banks. I came across <a href="http://www.investopedia.com/terms/b/bankers-bank.asp" rel="nofollow">this</a> 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 <a href="http://www.investopedia.com/terms/c/charter.asp" rel="nofollow">this</a>, 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.</p>

<p>Sounds like this is referring to a <a href="https://en.wikipedia.org/wiki/Central_bank" rel="nofollow">central bank</a>, which is a standard fixture of fiat monetary systems.</p>

<p>The central bank regulates the supply of money, in part by setting the terms under which retail/commercial banks can operate, borrow, and lend.</p>
