Izabella Kaminska gets confused on 100%-reserve banking, or collateral, unless it’s… wait, I’m confused now

Meanwhile, Izabella Kaminska in the FT had an interesting (as usual), but very confused and confusing, blog post. I asked whether or not she was reading my blog given that some of her claims pretty much reflect mine (she calls the shadow banking system a “decentralised full-reserve banking system that just happens to run parallel with the official fractional system we are used to.” Compare that with my “[…] parallel 100%-reserve banking system. The shadow banking system is effectively some version of a 100%-reserve banking.”). But the similarities stop here. She sounds very confused… She gets mixed up between various terms, principles and concepts and tries to hide it behind quite complex wordings.

She mixes collateralised lending with 100%-reserve and uncollateralised lending with money creation. They are in fact totally unrelated. A bank or shadow bank can be fractional-reserve-based or 100%-reserve-based, which simply relates to whether or not a bank lends out a share of its deposits or if it maintains them in full in its vaults. Collateralised lending is, well, just lending provided against collateral (which can be almost any type of assets). Both fractional and 100%-reserve banks can lend against collateral in order to minimise the risk of loss in case of default. 100%-collateralised lending is not 100%-reserve.

True, 100%-cash collateralised lending could be thought of as some form of 100%-reserve banking as the cash reserve at the bank would virtually never depart from the deposit base amount. For example, if a fractional bank collects USD100 in deposits and lends out USD90, it only keeps 10% of cash deposits in reserve. If, though, it lends out USD90 collateralised against USD90 of cash, then it ends up with USD100 in its vault, the same amount as the deposit base (although there will be limitations on the liquidity of the cash as the collateral will likely be ‘stuck’ until repayment or default). But, following her claim, a mortgage bank would be a 100%-reserve bank as the value of the housing portfolio on which lending is secured is worth more than the amount of lending. This is obviously wrong. Unless houses are now a generally-accepted medium of exchange?

Then she claims that “the official banking sector, for example, has the capacity to make uncollateralised investments in growth areas it feels are promising regardless of whether borrowers have collateral, or whether they can be fully funded.” Not really. First, banks usually collateralise between a quarter and more than 100% of their lending. Second, “uncollateralised investments in growth areas it feels are promising regardless of whether borrowers have collateral” is called venture capital and is clearly not what banks do. Venture capital funds, business angels, and some crowdfunding and P2P platforms are here for that (you could also probably add the junk bond market to the list). She then adds that, in contrast to banks, “the shadow banking sector’s strength, of course, is that it is prepared to service those entities (whether directly or indirectly) the official banking sector is not prepared to service, thanks to a greater emphasis on collateral or funding.” As I just said, this is not the case. Venture capital-type investments cannot accept collateral as… there is none! This is why they are high-risk.

According to Izabella, there is a reason why shadow banks cannot create money: their use of collateral. While it is true that (most, probably all) shadow banks cannot create money, it is not because they lend against collateral as described above. A lot of shadow banks don’t lend against collateral: think most money market funds, P2P lending, hedge funds, mutual funds, payday lenders…or simply the bond market! But they don’t create money either! They only transfer cash.

In the comment section she also seems to claim that fractional reserve banking is an innovation of our modern banking system. Where did she get that? Fractional reserves have been used since antiquity: the use of the ‘monetary irregular-deposit’ contract in classical Roman law gave rise to fractional reserves as deposits were mixed with other ones of equivalent nature (as opposed to the mutuum, or monetary loan contract, which is similar to what we could describe as today’s mutual funds for example). Despite the illegality of lending out irregular-deposits, some bankers took advantage of the fungibility of money, and of the fact that many irregular-deposits were rarely withdrawn, to lend out a part of their deposit base. The ‘bank’ of Pope Callistus I (see photo) failed as it was unable to return the irregular-deposits on demand. Other examples of failed banks exist at this period but fractional reserves really took off from the late middle ages in Europe.

Not everything is wrong in her article as I mentioned at the beginning of my post. She’s right to claim that regulation would only displace risk to another corner of the financial system that shadow banking is merely a response to the regulatory-incentivised under-banked part of the economic system, and that P2P lending is a kind of shadow banking. But too many confusions or misunderstandings around collateral, money creation, bank funding, bank reserves, etc., obfuscate the topic.
