In the unfolding contest over the future of money, Europe faces a critical inflection point.
While stablecoins are becoming more prominent as retail payment tools, their proliferation also raises significant questions about the architecture of modern financial systems, particularly in relation to monetary sovereignty.
As the US accelerates efforts to mainstream dollar-backed stablecoins, the EU must decide whether to passively observe or actively shape the outcome.
Stablecoins and Mainstream Payments
Historically viewed as mere instruments for crypto investors seeking refuge from volatility, stablecoins are now edging into mainstream payment ecosystems.
This evolution risks undermining the central role of sovereign currency and could, over time, erode trust in traditional monetary anchors – chief among them, the euro.
The US, under recent executive initiatives, is embracing the notion of a lawful, globally circulating stablecoin regime.
With Donald Trump signalling strong support for crypto markets, American legislators are poised to enshrine stablecoin growth into law.
European Caution
By contrast, Europe’s approach remains cautious.
Though the Markets in Crypto-Assets Regulation (MiCA) provides a pioneering framework for crypto oversight, it stops short of adequately addressing the growing overlap between stablecoins and traditional forms of money.
The risk for the euro is not outright dollarisation, but rather the creeping substitution of stablecoins for everyday transactions, subtly displacing central bank money as the unit of account and medium of exchange in digital contexts.
Stablecoins pose conceptual challenges too. Despite their name, they are neither truly “stable” nor actual “coins.”
Like money market funds, their value hinges on the liquidity and creditworthiness of their underlying assets – attributes that can falter under stress.
In contrast, central bank money offers settlement finality, regulatory oversight, and systemic trust, all of which remain out of reach for decentralised tokens operating outside central banking frameworks.
Digital Euro
The much-anticipated digital euro could offer a public sector counterweight to private stablecoins, but its effectiveness as a retail payment instrument is far from guaranteed.
Designed as a supplementary payment option rather than a transformative one, the digital euro’s commercial appeal remains uncertain.
As such, policymakers would do well not to rely solely on its rollout to defend monetary sovereignty.
A more robust solution may lie in tightening the boundaries between traditional money and asset-backed tokens.
Interoperability should not be unconditional.
While MiCA mandates 1:1 convertibility of stablecoins with fiat money, such parity may undermine the distinctiveness of central bank currency.
Instead, introducing controlled friction – via settlement lags, conversion costs, or transaction limits – could help preserve the primacy of sovereign money without stifling innovation.
For 5,000 years, money has acted as a shared measure of value and reliable settlement tool.
As digital innovation continues to reshape the financial landscape, European regulators must ensure that new instruments like stablecoins are treated not as equivalents to central bank money, but as distinct entities with different risk profiles and regulatory needs.
The euro’s integrity, and Europe’s role in the next chapter of monetary evolution, hinges on what Brussels chooses to do next.
The ball is firmly in Europe’s court.
