Four page reference on bank loan loss accounting shows the simplified accounting structure of a bank balance sheet and income statement:
The cash account in the paper above is a poor term. It should be called the Reserve account and includes currency on hand (vault cash, teller drawers) as well as Central Bank exchange settlement funds which I call bank reserves.
This talk about bank accounting and operations is accurate although the discussion of bank capital (loan loss allocation) is overly simplified and Richard does not stress the importance of each bank's ability to make interbank reserve payments as it's primary liquidity constraint:
In other words, banks have to pay interest to attract deposits to keep reserve payments flowing in the interbank payment system, and banks have to pay dividends to shareholders to retain equity claims which take the first loan loss in the bank's loan portfolio. Individual banks don't get a free lunch when creating loans and deposits from thin air although the bank sector as a whole has overdraft privileges with the Central Bank so loans indeed create deposits in the aggregate financial economy. But an individual banker will tell you his books have to balance and he faces capital and liquidity requirements. The bank itself resembles a non-bank financial intermediary which must borrow and issue equity to hold its assets or lose control over the assets if the intermediary is liquidated by market forces or resolved in bankruptcy.
Gold money under the gold standard would just be items in the bank and non-bank cash accounts held on balance sheets:
Gold is a non-financial asset, meaning it is not the liability of a counterparty, however the structure of financial intermediaries under the evolution of accounting and law means there is never enough gold to repay all creditors and equity investors in a non-bank or bank business venture when the creditors and investors all try to convert their long term risk positions into liquid money. The modern financial system generates credit and finance instruments when everyone puts on risk (risk on) and the balances sheets are forced to unwind or deleverage when everyone tries to take off risk (risk off). Gold could not be "printed" in a risk off market and banks would be forced to liquidate assets to convert investments into gold payments. Modern central banks can print money by buying assets from banks or non-banks, which we call Quantitative Easing or Large Scale Asset Purchases (LSAPs). Governments can print money by issuing net new Treasuries via deficit spending usually to stimulate the economy and/or help the Central Bank prevent rapid asset price deflation in a risk off market panic.
