On the Nature of Banks - 'Insured' vs. 'In Specie'

I've never been entirely sure why banks confuse people so much. They really are very simple creatures. They make loans and back those up with deposits and other borrowings, charge a margin for one over the other in return for making an underwriting decision, and undertake to swap their liabilities around in various manners to maintain their liquidity.

And that's about it really. In fact all the problems start happening when you let lending banks do anything much more than this.

In a monetary system there are two main ways of setting up a banking structure. You can either have an 'in specie' system where the central bank issues actual liabilities and assets in the denomination currency to back the banking system (also known, inaccurately, as 'full reserve'), or you can have an 'insured' system where the central bank promises to issue actual liabilities and assets when certain events happen. For the rest of the time they remain 'contingent'.

This is what a commercial bank's balance sheet looks like in an 'insured' scheme:

Insured Deposits are those covered by the country's deposit insurance scheme (here in the UK it is 100% of the first £85,000 per person). All other deposits are uninsured or 'bailed in'.

Bank Bonds are corporate bonds issued by banks, issued on the money markets usually as traded securities. Examples include Permanent Interest Bearing Shares (PIBS), or Bank Subordinated Bonds.  These differ from the 'fixed rate bonds' that you hear banks selling, which are really just a form of term deposit.

Preference Shares are very similar to bank bonds but have a lower claim on the banks assets and therefore should pay a high interest rate to offset the risk. They are also classed as equity instruments rather than debt instruments.

Ordinary shares are the normal shares/common stock in the bank and which receive the bank's variable dividend payment.

If a bank's lending turns out to be bad and the loan section therefore shrinks, then the losses accrue to the right hand side of the balance sheet from the bottom upward. Ordinary shareholders lose out first, then preferred shareholders, all the way up to insured depositors.

The Bank is then insolvent and the central bank (or other authorised government body) steps in to administer the failed bank under the insurance arrangements. Where necessary it issues Central Bank Reserves to pay the insured depositors, and writes the loss out to its own balance sheet. The assets of the failed bank are sold to other market participants, the central bank recovers its loss form those assets and if there is anything left the other creditors get a fraction of their investment back. 

So in reality the insured depositors don't really hold their money with the commercial bank. They hold it with the central bank because the risk has been transferred via the insurance policy. Which is what insurance was invented for. 

Change the accounting policy of a bank to require that it shows the insured element explicitly and you get this:

Change it again to require that the balance sheet is split into responsibility areas and you get this:

Remove the word 'contingent' and that is what an 'in specie' system will look like under the current policy settings.

Any other magical powers ascribed to 'in specie' systems are either due to hidden policy changes, (which can be just as easily be applied to an 'insured' system), a misunderstanding of how banks or money things actually work on the part of those making the claims, or (mostly) just plain political propaganda.

'In specie' and 'insured' systems are operationally identical. You can transform the balance sheet of one into the other. Nothing substantive changes. That's why MMT has always been agnostic on the subject.

“Insured Deposits are those covered by the country's deposit insurance scheme (here in the UK it is 100% of the first £85,000 per person).” The glaringly obvious problem there is that that “insurance” (paid for as it is by taxpayers) amounts to a SUBSIDY of the banking industry. In the US, the TBTF subsidy comes to the same thing. And subsidies, as it explains in the introductory economics text books, misallocate resources, i.e. they reduce GDP.

Put another way, those subsidies are all part of the “socialism for the rich” movement, which most politicians and ordinary citizens seem quite happy with, for some bizarre reason.Banksters have got politicians and ordinary citizens suckered.

As to the actual size of the subsidy, the total amount of subsidised loans made available to banks in the recent crisis (in the US and Europe) came to $29trillion according to Randy Wray (see link below). That’s about double US GDP. As for any reader who’s jaw doesn’t drop on reading that figure, all I can say is there’s something wrong with their jaw.

You will have a similar 'subsidy' under any other system - because they are *operationally identical*. (How many more times do I have to say that).

You really do need to get over the obvious hang up here. The country needs a certain amount of lending to happen given the other policy settings within government - or there will be a depression.

So *given those policy settings* the central bank has to make sure that the banks are funded with money at the correct price to get that level of lending. (And yes they are funded under the current system - banks can only lend to the extent that they can backfill with deposits).

Don't forget that in the UK there is always National Savings, which attracts away deposits at an interest rate. The Banks are competing with that drain all the time to attract funding.

So it is completely pointless getting angry about something that is simply a direct result of the policy settings that the elected government have implemented.

Instead change the government to one that has different policy settings that has less reliance on pushing private debt.

No need to change the system.

"failed bank are sold to other market participants, the central bank recovers its loss"
What if it doesn't recover its loss? Could this be conceivable? What happens then?

"What happens then?"

The central bank is the depositor in the bank and takes a loss. It writes this off against its own equity, and then creates some more by expanding its balance sheet or run with negative equity.

Currency issuers don't suffer with losses because there is nobody to shut them down. They exist due to sovereign power.
