The banking system is a pull based system. You go to a bank, the bank gives you a loan and creates the money as they deposit it on your account, they literally don't care what the fed does rather the fed has no choice but to create more reserves if the commercial bank requests them. The commercial bank does something like "You wouldn't risk the banking system to collapse if you refuse me reserves would you?" The central bank then goes "Eh, I guess I have no choice, we have to do whatever it takes after all".

Meanwhile internet propaganda constantly tells people that it is a push based system, that somehow the Fed is telling the commercial banks to issue more loans and then for every dollar in created reserves the commercial bank calls and naggs you that you should borrow more and somehow the citizens just keep falling for it every single time.
