Simple, but completely wrong. The bank never loans your money. When it wants to originate a loan it creates new deposits from nothing.

  That is not how fractional reserve banking works, people - or, to me at least, it gives a wrong impression. Say we are in a fractional reserve banking system, where the required reserve is 10%. I deposit $1M at the bank. My bank can now lend $900K to you. You can now deposit $900K back at your bank. Your bank can now lend $810K to someone else, and so on and so on. The geometric sum of this is "1/reserve_ratio"; so if there's a 10% reserve ratio, then the initial $1M deposit can lead to $10M of loans outstanding. No single bank is loaning out more than is being deposited with it.

    This used to be true, but hasn't mattered for a long time. The reserve requirement is zero for most (all?) US banks. https://www.federalreserve.gov/monetarypolicy/reservereq.htm https://www.federalreserve.gov/monetarypolicy/reservereq.htm

      It doesn't matter because no banks have been anywhere near the reserve requirements that were previously in effect. The change to the "ample reserves" regime is just a tacit admission that lending is not functionally limited by reserve ratios in the U.S. at the moment.

        I'm sure you know, but (based on discussions that took place at the time of the announcement back in 2020) I know a lot of people who leapt directly to the assumption that the removal of the reserve requirement was so that banks could "create even more money out of thin air than they were previously allowed to do". I hope you don't mind me clearing that misconception up, even if it's not for your benefit!

      - howeyc 5y ago
        That's how it has been for a while, as the bank of England paper explains. The key is that the bank is "on the hook" for being able to get that money back eventually. So they don't just loan indiscriminately.
        SilasX 5y ago
        But “eventually” can mean “now, as an easy loan from the central bank/lender of last resort”, which trust the solvency of the bank’s loans.

      So basically all commercial banks are free to issue unlimited loans (and create unlimited new dollars)?
      - User23 5y ago
        Basically, yes. There are “capital” requirements, but as far as I can tell that’s basically just laundering their loan business by trading equity with peer banks, which are of course largely based on loan performance.

    - danielmarkbruce 5y ago
      The capital requirements result in something similar. In the end, a loan by JPM of $100 is backed by about $90 of deposits and about $10 of JPM equity. In practice JPM has more capital than that, but there is some adjustments to the loan amount given the risk of any loan etc. So, JPM needs more equity if it wants to ramp up it's loans.
  - RobertoG 5y ago
    That's not how it works. Banks lend and then try to find reserves, after the fact, because they have legal requirements. No bank loss a good lending business because they have not reserves enough. When a bank make a loan, there are two possibilities: they have enough reserves, then they don't need to do anything. Or they don't have enough reserves, so they have to borrow them from other banks or from the central bank. If they borrow them from other banks they are creating demand for reserves in the inter-bank market. That makes the interest rate go up. The central banks don't try to control the quantity of money, but the interest rate. If there are a lot of demand for reserves and the Central Bank don't add reserves to the system the interest rate will go up. So, the Central Bank add or retire reserves in order to keep the interest rate in the range they want. The quantity of money is decided by the demand of lending in the economy. The Central Bank can choose to try to control the quantity of money or the interest rate, but not both. All modern Central Banks try to control the interest rate.

  Except that the people who are loaned money withdraw it pretty quickly, and then the bank does need cash from deposits (or from inter-bank lending, but the net amount of that is zero).

      Banks cover their funding needs through the interbank market that provides the overnight loans required to balance their books at the end of the day. Banks will raise deposit rates to attract deposits if they constantly find that they need to go to the interbank market to balance their books because it is cheaper. The discount window is used when the bank is unable to access the interbank market which is usually an indicator the bank is expected to fail. The discount window provides liquidity for high quality assets at high costs (which is why it is called the discount window). If the bank runs out of high quality assets and can’t raise capital it becomes insolvent (bankrupt) and the FDIC takes over the bank and winds it down.
      - JumpCrisscross 5y ago
        > will raise deposit rates to attract deposits if they constantly find that they need to go to the interbank market to balance their books because it is cheaper This is true for the largest banks. For many smaller banks, interbank lending is cheaper than deposits. Particularly if those deposits must come from new customers. Your model is roughly correct over long, strategic time periods. But in tactical timeframes, deposits are assumed fixed or lightly. (In fact, the post-97 role of money centre banks has been to attract deposits to then lend to smaller banks.)

  - epistasis 5y ago
    I don't think that's a fair interpretation of money or of what banks are doing. Imagine that a business has $1M/month of revenue, mostly through a quote and purchase order system where the terms are typically net 30. Then imagine they turn to net 60 or net 15, either increasing or decreasing their cashfrow for a single month. The terms of the invoicing are debt creation. And all debt creation is money creation. Thinking of money like swapping gold really limits the reality of how money has always functioned in our society. Money and debt are social relations, bonds between people, bonds between individuals and a larger collective. It's a human creation, that's been created again and again over time, and the idea of a money-less society is pretty much impossible to come up with. We must think of money not as an external thing, outside of humanity, but as an essential part of what humans do and create.

  Correspondent banking just seems messed up at the incentive layer... Seems like there is an incentive for banks to just credit free money into each other's accounts... Surely they can create lots of smaller (low profile) banks with accounts all over the place then use this mechanism to print free money for themselves to expand the money supply ad-infinitum. The attack surface is massive. With the same money being loaned and re-loaned across thousands of different banks, how could anyone possibly detect fraudulent currency creation (and distinguish it from genuine deposits)? It just takes one bank to act unethically in a chain of several thousands in order to subvert the entire system. Even without unethical behavior, it seems like a small chance of human error, when applied across thousands of banks, would cause accidental printed money to leak into the system. For example, there have been many news reports of banks accidentally crediting people with 100x the money which they were supposed to receive; what about all the times when such error occurred but was not detected and did not make the news? That money still found its way into the economy and still contributed to inflation. The problem can be simply summarized as too many single points of failure.

    A homeowner can take $100,000 from a home equity line of credit and drop it into his savings account and create $100,000 in new dollars with a button click. The bank didn’t need to “get” deposits to make this happen as the deposits are created when the homeowner took out the loan. The new dollars and the liability are just entries in the banks balance book but the dollars can be spent like any other dollar at that point. If the next day the homeowner moved all the money back and paid off the equity the dollars are destroyed. This is how a bank works. The size of a banks balance sheet and the number of dollars it can create is constrained by the amount of shareholder equity (by regulation). Regulators typically require a 10 to 1 ratio of loans to capital which has potential for fraud. Just imagine if you had 10 banks levered 10 to 1 and you took all the deposits and put them on black at the local casino. Half of your bets would yield a 10x return on capital and the others you’d lose all your capital (and all your depositors money) but on average you’d make 5x. Because of the risk banks are highly regulated and regulators require that named individuals that can be held personally and criminally liable for fraud and auditors who also can be held personally and criminally liable as well.

  If banks could create money out of nothing, then they could not be damaged by a bank run. They would just create enough money to satisfy the run. The reality is that they can be damaged (or bankrupted) by a bank run, because their books do need to balance. That is why the U.S. created FDIC insurance (which is funded by the banks themselves).
  - ilammy 5y ago
    These are unrelated things. The reason bank run collapses are a thing is that the deposits aren't just sitting there as cash in the vault. Banks invest the deposits and those can't always be liquidated quickly and efficiently in case of a bank run. If the bank doesn't have enough collateral to borrow the needed cash, the bank is forced to do firesales which is not the best business strategy. Nobody will lend you money when you're selling off your property at a huge discount.
    - danielmarkbruce 5y ago
      They are certainly related. The reason the deposits aren't sitting there is because they went flying out the door to fund the loans the bank made. If the bank could just fund loans out of thin air, they wouldn't need bank deposits in the first place. Just go look at the balance sheet of a real bank. You'll see it all balances very nicely - there are assets (mostly loans to businesses and consumers), liabilities (mostly deposits) and shareholders equity (mostly money shareholders put up). Here is one to look at: https://www.sec.gov/ix?doc=/Archives/edgar/data/72971/000007297122000096/wfc-20211231_d2.htm https://www.sec.gov/ix?doc=/Archives/edgar/data/72971/000007... All those 100's of billions of loans on the books are funded. Money comes in, money goes out, nothing much has changed in 1000s of years.

  This is a pretty awful doc. While technically it's not wrong, it doesn't continue to follow the flow long enough. The example given of "creating money" by creating a balance in someone's account is meaningless. In practice, the money is almost immediately sent to... the seller of the house.

The idea banks make money out of thin air is a stupid idea, it sounds clever but does nothing except muddy the waters. Nobody used to say the local grocer was "creating money out of thin air" when they created a line of credit.

    "Do I have enough assets so I can in fact send the money to the seller of the tractor you just purchased?" Yes you do. Because it is just an internal transfer within the bank. From your account at the bank, to the sellers account at the bank. If it is to another bank, then that destination bank becomes a depositor in the source bank, which creates a loan to the source bank and a new deposit for the seller is created in the destination bank. The destination bank does this otherwise the seller will move their bank account in disgust to the source bank - who does promise to complete the transfer. All very simple and the way it has been done for centuries. It's all loans create deposits - book entries.
