Earlier quoted context omitted.
You didn’t say "if the banking system as a whole has $1 million in deposits (of actual cash that people gave to the bank to put in their checking accounts) the system banking as a whole can make $10 million in loans" [and there will be in the end $11m in deposits in the banking system as a whole, offsetting the $1m in reserves and $10m in loans] You said "if a bank has $1 million in deposits (of actual cash that peop…
I mean apologies if I'm misunderstanding what you're saying - but as far as I can tell you're claiming the leverage ratio for a bank is 0.9:1 and I'm saying it is 9:1. If that's the case only one of us can be correct. It doesn't help that you're conflating the terms "deposits" and "reserves". Deposits are liabilities of the bank, while reserves are assets held in their account at the central bank. If the banking syst…
Liabilities : deposit $1m
Assets : reserves $1m
Now you can lend $900k to someone, who takes the money and tranfers it to someone else’s account in another bank to buy bitcoins or whatever. Your bank has now Liabilities : deposit $1m
Assets : reserves $100k, loan $900k
And you cannot make more loans until you increase your reserves which means getting new deposits (so we’re no longer talking about a bank with $1m in deposits).Say you get an additional million in deposits, your bank has now
Liabilities : deposits $2m
Assets : reserves $1.1m, loan $900k
And it could lend and additional $900k.Alternatively, it could get funding from another source like borrowing from banks of issuing bonds. For example
Liabilities : deposit $1m, bond $1m
Assets : reserves $1.1m, loan $900k
I don’t think any of this is controversial, let alone wrong. By the way, for simplicity in those balanced sheets the “reserves” is all the funding available which has not been lent, not just the required reserves ($100k for $1m in deposits, etc.)> If the banking system as a whole is leveraged 9:1, that implies each individual bank is leveraged approximately 9:1.
One of the main points of the paper under discussion is that this doesn’t happen. Reserves are not a binding constraint on lending.
[0] I don’t know if it makes much sense to talk about whether it is “actual cash”. Maybe my employer took a loan to pay me, maybe not. Maybe it was in cash, maybe by cheque, maybe by bank transfer. Would that change anything?
