One of my recent posts flagged some useful work that JP Koning had shared summarising four different regulatory strategies USD stablecoins issuers have adopted.
The New York Department of Financial Services (NYDFS) trust company model [Paxos, Gemini, BUSD]
The Nevada state-chartered trust model [TrueUSD, HUSD]
Multiple money transmitter license model [USDC]
Stay offshore [Tether]
If I read this post from Circle correctly, we can now add a fifth strategy; the Federally-chartered national commercial bank model. For those with a historical bent, this might also be labelled the “narrow bank” model or the “Chicago Plan” model.
Here is a short extract from the Circle post …
Circle intends to become a full-reserve national commercial bank, operating under the supervision and risk management requirements of the Federal Reserve, U.S. Treasury, OCC, and the FDIC. We believe that full-reserve banking, built on digital currency technology, can lead to not just a radically more efficient, but also a safer, more resilient financial system.
We are embarking on this journey alongside the efforts of the top U.S. financial regulators, who through the President’s Working Group on Financial Markets are seeking to better manage the risks and opportunities posed by large-scale private-sector dollar digital currencies.
What is interesting for students of banking is the parallels that Rubinstein notes between MakerDAO and the free banking systems that evolved during the 18th and 19th centuries. Scotland is one of the poster children of this style of banking and we can see a legacy of that system (albeit much more regulated and so not true free banking) in the form of the private bank notes that the three Scottish banks still issue in their own name. He quotes Rune Christensen (founder of MakerDAO) describing the way in which his project accidentally developed a form of fractional reserve banking”
In the very beginning of the project, I remember we didn’t even realise, in the beginning of Maker, that we were essentially just building a protocol that did the same things as fractional reserve banking, did something very similar to how a banking balance sheet works and we were just implementing that as a blockchain protocol. We thought we were doing something completely, totally different from how money usually worked in the traditional sense.”(source)

This statement should be qualified by the fact that they can only do this (i.e. replicate fractional reserve banking) because the currency of the decentralised bank is a form of money called Dai. Fractional Reserve Banking has proved to be a risky form of financial technology in the conventional banking system which has developed a range of tools to manage that risk (e.g. capital adequacy and liquidity requirements, deposit preference arrangements often coupled with deposit insurance to insulate the “money” part of the bank balance sheet from risk, high levels of supervision and other restrictions on the types of assets a bank can lend against).
MakerDAO has a stabilisation mechanism that employs “smart contracts” that manage the price of Dai by managing its supply and demand. The pros and cons of the various stabilisation mechanisms that underpin stable coins like Dai is a topic for another day.
Rubinstein describes the MakerDAO lending and “money” creation process as follows:
The bank he devised to create his money … works like this:
An investor comes into Maker DAO for a loan. He (yep, usually he) has some collateral he’s happy to keep locked in a vault. Right now, that collateral is usually a crypto asset like Ethereum. For every $100 worth of crypto assets, Maker is typically prepared to lend $66 – the gap adding a buffer of protection against a possible fall in the value of the collateral. Maker accepts the collateral and advances a loan, which it does by issuing its Dai money.
At this stage I am not sure where this is headed. It is not clear, for example, if the purpose of this “bank” is simply to create more Dai via trading in crypto-assets or to build something that translate outside CryptoLand. Rubinstein quotes Rune Christensen himself stating that
I don’t think that it will necessarily replace everything… The traditional financial system will actually largely remain the way it is. It will just replace certain parts of it that right now are really bad and really old… those things will be replaced with DeFi and blockchain, but the actual bank itself probably will remain.”
I am a long way from figuring this out but Marc’s post is I think worth reading for anyone who want to understand where these new (or possibly reinvented) forms of finance are heading. To the extent that DeFi is reinventing things that have been tried before, I suspect it would be useful to reflect on why free banking is no longer the way the conventional banking system operates. That is another topic for another day.
Given the central role that money plays in our economy, understanding how the rise of digital money will play out is becoming increasingly important. There is a lot being written on this topic but today’s post is simply intended to flag a paper titled “The Rise of Digital Money” that is one of the more useful pieces of analysis that I have come across. The paper is not overly long (20 pages) but the authors (Tobias Adrian and Tommaso Mancini-Griffoli) have also published a short summary of the paper here on the VOX website maintained by the Centre for Economic Policy Research.
Part of the problem with thinking about the rise of digital money is being clear about how to classify the various forms. The authors offer the following framework that they refer to as a Money Tree.
This taxonomy identifies four key features that distinguish the various types of money (physical and digital):
Type – is it a “claim” or an “object”?
Value – is it the “unit of account” employed in the financial system, a fixed value in that unit of account, or a variable value?
Backstop – if there is a fixed value redemption, is that value “backstopped” by the government or does it rely solely on private mechanisms to support the fixed exchange rate?
Technology – centralised or decentralised?
Using this framework, the authors discuss the rise of stablecoins
“Adoption of new forms of money will depend on their attractiveness as a store of value and means of payment. Cash fares well on the first count, and bank deposits on both. So why hold stablecoins? Why are stablecoins taking off? Why did USD Coin recently launch in 85 countries,1 Facebook invest heavily in Libra, and centralised variants of the stablecoin business model become so widespread? Consider that 90% of Kenyans over the age of 14 use M-Pesa and the value of Alipay and WeChat Pay transactions in China surpasses that of Visa and Mastercard worldwide combined.
The question is all the more intriguing as stablecoins are not an especially stable store of value. As discussed, they are a claim on a private institution whose viability could prevent it from honouring its pledge to redeem coins at face value. Stablecoin providers must generate trust through the prudent and transparent management of safe and liquid assets, as well as sound legal structures. In a way, this class of stablecoins is akin to constant net asset value funds which can break the buck – i.e. pay out less than their face value – as we found out during the global financial crisis.
However, the strength of stablecoins is their attractiveness as a means of payment. Low costs, global reach, and speed are all huge potential benefits. Also, stablecoins could allow seamless payments of blockchain-based assets and can be embedded into digital applications by an active developer community given their open architecture, as opposed to the proprietary legacy systems of banks.
And, in many countries, stablecoins may be issued by firms benefitting from greater public trust than banks. Several of these advantages exist even when compared to cutting-edge payment solutions offered by banks called fast-payments.2
But the real enticement comes from the networks that promise to make transacting as easy as using social media. Economists beware: payments are not the mere act of extinguishing a debt. They are a fundamentally social experience tying people together. Stablecoins are better integrated into our digital lives and designed by firms that live and breathe user-centric design.
And they may be issued by large technology firms that already benefit from enormous global user bases over which new payment services could spread like wildfire. Network effects – the gains to a new user growing exponentially with the number of users – can be staggering. Take WhatsApp, for instance, which grew to nearly 2 billion users in ten years without any advertisement, based only on word of mouth!”

The authors then list the risks associated with the rise of stablecoins:
The potential disintermediation of banks
The rise of new monopolies
The threat to weak currencies
The potential to offer new opportunities for money laundering and terrorist financing
Loss of “seignorage” revenue
Consumer protection and financial stability
These risks are not dealt with in much detail. The potential disintermediation of banks gets the most attention (the 20 page paper explores 3 scenarios for how the disintermediation risk might play out).
The authors conclude with a discussion of what role central banks play in the rise of digital currency. They note that many central banks are exploring the desirability of stepping into the game and developing a Central Bank Digital Currency (CBDC) but do not attempt to address the broader question of whether the overall idea of a CBDC is a good one. They do however explore how central banks could work with stablecoin providers to develop a “synthetic” form of central bank digital currency by requiring the “coins” to be backed with central bank reserves.
This is effectively bringing the disrupters into the fold by turning them into a “narrow bank”. Izabella Kaminska (FT Alphaville) has also written an article on the same issue here that is engagingly titled “Why dealing with fintechs is a bit like dealing with pirates”.
The merits of narrow banking lie outside the scope of this post but it a topic with a very rich history (search on the term “Chicago Plan”) and one that has received renewed support in the wake of the GFC. Mervyn King (who headed the Bank of England during the GFC), for example, is one prominent advocate.
Hopefully you found this useful, if not my summary then at least the links to some articles that have helped me think through some of the issues.
