Niall Ferguson, in his sweeping history of money book The Ascent of Money, makes an important observation
"The evolution of money has been a process of gradual dematerialisation."
From gold coins to paper notes to digital ledger entries, each step in the evolution has moved money further away from a physical thing toward a shared belief. Nowhere is this more relevant today than in our world of fiat currencies based on notional values, which are themselves moving steadily toward digital form, adding another layer of abstraction. And digital assets, like stablecoins, are at the next dimension in this shift.
Origins:
Why stablecoins exist at all
Stepping back a little, why did stablecoins come to exist at all? it came down to crypto market settlements. Back in early 2010s, as Bitcoin trading was gaining real ground on early exchanges, crypto markets were trading around the clock, 24 hours, 7 days a week. Whenever people wanted to take profits or reduce risk, they needed somewhere to park value that was not volatile. But moving money in and out of bank accounts is slow. The banking system runs on business hours. The crypto market doesn't. So people needed a stable asset that could move on a crypto network, any time, without going through a bank. Stablecoins solved that.
Over time however, stablecoins stopped being just a workaround for crypto traders. They became genuinely useful for moving money across borders, faster and more cheaply than traditional bank transfers. The cross-border benefits were realized, almost like a familiar pattern of accidental usefulness that we have seen in other industries.
This dynamic has precedent in history of banking and financial transactions.
A financial instrument created to solve one problem and then becoming very useful for something much bigger, has of course happened before. In 17th century Amsterdam, merchants trading across long distances faced a version of the same challenge of moving value faster than the available infrastructure could carry it. Economic historian Jan de Vries, writing about the commercial revolution of early modern Europe, describes how merchants needed financial instruments that could move faster than coins could physically travel. They created bills of exchange: IOUs between trusted parties that circulated as a kind of proxy money. Not officially issued by any state. But accepted widely enough to do the job.
What is similar about the Amsterdam example and what we just saw with crypto markets is how these bills evolved. They started as a simple workaround for slow settlement between trading partners. But over time, as historian Herman Van der Wee noted in his research on Antwerp and Amsterdam's financial markets, the bills of exchange became the circulatory system of European trade, moving value across cities and countries in ways that the underlying coin-based system never could have managed at that speed or scale.
Stablecoins are following a similar arc. Started as workaround, but now taking on other roles.
Why trust always concentrates
Trust isn't distributed equally, it concentrates around whatever has already earned it. The Amsterdam bills of exchange reached for the most trusted thing available when it came to collateral. The bills clustered around the most accepted currencies of their day.
You can see this play out even further in Amsterdam. Herman Van der Wee, in The History of European Banking, describes how the private merchant system that preceded the Bank of Amsterdam already understood this:
"...the foundation of the deposit bank in Amsterdam had been preceded by private initiatives of merchants who deposited full-bodied coins... Lenders were protected from repayment in debased coin, for the bankers undertook to pay back the deposits in the same high-quality coins as they had received."
The merchants were building and operating for convenience, but on the back of a promise. That what you put in is what you get back, undiluted. The Bank of Amsterdam came along and made official what trust had already worked out. Stephen Quinn and William Roberds describe exactly how, in their study of the Bank of Amsterdam's rise in the American Economic Review:
"The Bank [of Amsterdam] provided a uniform and secure money (bank money) for the settlement of large-value transactions... By providing a stable unit of account and a secure means of payment, the Bank reduced the transaction costs and risks associated with the use of a variety of circulating coins."
The point to note here is this - trust was not built top down by central banks. Private merchants built trust informally first. But backed by a stable value surrogate. Because it was reliable. Then banks and institutions formalised it.
The shift:
- Interoperability isn't trust. Different systems talking to each other doesn't answer why people pick one currency over another.
- Trust doesn't transfer easily. Trusting a dollar stablecoin is one thing. Trusting a local one means trusting a lot more behind it.
- Governments don't share currency control. A private stablecoin competing with a national currency is a threat most governments will want to closely regulate.
- Domestic strength doesn't travel. Local-currency stablecoins make sense at home, but the moment money crosses a border, it's back to the same trust problem.
One of the livelier debates in the stablecoin world right now is about interoperability: whether different stablecoins, different blockchains, and different digital currency systems will eventually be able to talk to each other seamlessly. If that happens, the argument goes, then using a Euro stablecoin or a Singapore dollar stablecoin would be just as easy as using a US dollar one. The friction is reduced.
That is a reasonable. But I think it misses something important about why people choose one currency over another in the first place. Interoperability solves a plumbing problem, but not the trust problem.
The trust problem - it does not transfer easily
Think about what happens when someone in a country with serious inflation gets access to a digital asset like a stablecoin for the first time. What do they want? They want to get out of their local currency. They want something that holds its value and is accepted widely. A stablecoin in their local currency gives them none of that. It's a digital version of exactly the thing they are trying to get away from. Making a weak currency digital doesn't make it attractive.
That's one problem. The other is simpler and has nothing to do with trust at all: dollar stablecoins already have a first-mover advantage in a network is hard to claw back. They have liquidity, with far more buyers and sellers on either side of every trade. They have distribution, accepted almost everywhere a stablecoin gets used. And they have institutional adoption that keeps compounding on itself. For a non-USD stablecoin to actually scale, it must do more than just exist. It has to be genuinely better for a specific reason in a specific context.
The government dilemma
Governments make this more complicated too. Governments outside the US are being asked to do two things at once, and those two things don't pull in the same direction. On one hand, they need to move fast to create the conditions for their own local currency stablecoins to scale, simply to avoid getting pulled into dollar dependency by default. On the other hand, the same governments want to keep monetary control for themselves, which is what CBDC experiments are really about. Encouraging private stablecoins and building a government-run digital currency are not the same instinct. They sit in tension with each other.
The local currency case — and its limits
Now, there are genuine cases for local currency stablecoins, and private issuers will find value of this. For purely domestic activity, like doing local payments, paying salaries, paying suppliers in the same market, holding savings in a familiar currency, a local currency stablecoin makes intuitive sense. And there will be businesses and contexts where this is genuinely useful.
But here is the thing. In most markets, local banking infrastructure for domestic transactions already works reasonably well. Moving money within a country, paying staff, settling with local vendors, these are not the broken parts of the system. Even in countries where digital banking systems are not yet there, and could encourage them to leapfrog to a stablecoin based system, the potential has a ceiling.
And cross-border is exactly where local currency stablecoins run into trouble. The moment it becomes about moving money across borders, it is back to the same questions of trust, reserves and acceptance. Who holds this currency at the other end? How easily can it be converted? A Singapore dollar stablecoin moving from Singapore to a supplier in Brazil reintroduces all the friction that a dollar stablecoin was designed to remove. None of this means local currency stablecoins won't grow. They will, especially within their own regions. But that growth will likely stay regional for a long while, and the distance between that and the scale a US dollar stablecoin already operates at is not closing anytime soon.
So where does this leave us
Three things that I see:
The edge:
New networks are supposed to level the playing field. Unfortunately, they don't. They tilt it further toward whoever already had the advantage. What happens next tends to run counter to intuition and there are examples of this.
Stablecoins are a new network. And the thing flowing most powerfully through them, from the very beginning, has been the dollar.
"Stablecoins are more likely to reproduce the existing hierarchy of currencies than to flatten it."So here we are — and here is where I think this goes. The following seem likely.
"What if stablecoins are actually how dollar dominance gets written into the new layer of global finance, faster and more embedded than before?"That question doesn't answer itself. But it's worth pushing past the question mark.
But a trend is a trend is a trend; until it bends
As one economist, David Lubin, put it at a Chatham House discussion on dollar dominance.
“the dollar is the QWERTY keyboard of the international monetary system.”
Wrong battlefield:
I don't have a clean answer to how that will emerge. But I think it matters. The real innovation in this space is happening at the edges, where the USD versus local currency stablecoin battle barely registers. That's probably the only way the encoded advantage gets broken at all.
