The European Union's landmark crypto regulation, the Markets in Crypto-Assets Regulation (MiCA), has achieved its primary objective of making euro-denominated stablecoins among the safest in the world. But according to a new report from industry group Blockchain for Europe, that safety has come at a steep commercial cost — one that threatens to leave the euro permanently sidelined in the rapidly expanding global stablecoin market.

A Regulatory Laffer Curve

The report, drafted by European Central Bank official Ulrich Bindseil and Blockchain for Europe's Erwin Voloder, invokes the concept of a regulatory 'Laffer curve' to describe MiCA's unintended consequences. Just as excessive taxation can reduce total tax revenue, the authors argue that overly strict stablecoin rules have suppressed the very activity they were designed to govern.

The numbers are stark. According to data from DeFiLlama cited in the report, euro stablecoins currently account for less than 1% of global stablecoin volume — a figure that stands in sharp contrast to the euro's considerable weight in international trade and finance. The US dollar, by comparison, dominates the stablecoin landscape through tokens such as USDT and USDC, which collectively command the vast majority of market activity.

The Remuneration Ban: A Structural Handicap

At the heart of the critique is MiCA's prohibition on euro electronic money tokens (EMTs) paying interest to holders. The ban was conceived as a safeguard against stablecoins becoming deposit substitutes and destabilising the traditional banking system. In practice, however, the authors contend it has rendered MiCA-compliant euro tokens "at a particular disadvantage" in a positive interest rate environment.

While bank deposits and foreign currency stablecoins can embed or distribute yield through alternative mechanisms, euro EMTs are barred from doing so. The result, the report argues, is a product that is technically sound but commercially unattractive — safe enough to hold, but offering no incentive to do so over competing instruments.

Europe's Digital Currency Ambitions at Stake

The implications extend well beyond the stablecoin market itself. As digital payments and decentralised finance continue to grow, the currency in which transactions are denominated carries significant geopolitical and economic weight. A euro stablecoin ecosystem that fails to gain traction risks ceding further ground to dollar-denominated alternatives in global digital commerce.

The Blockchain for Europe report places these concerns within a broader policy debate, comparing MiCA's approach to those of other jurisdictions and urging European lawmakers to reconsider the regulatory framework before the competitive gap widens further.

A Call for Reform

Bindseil and Voloder stop short of calling for MiCA to be dismantled. Instead, they advocate for targeted reforms — particularly around the remuneration ban — that would allow euro stablecoins to compete on a more level playing field without abandoning the prudential safeguards that MiCA has established.

Whether European regulators will heed the call remains to be seen. MiCA only came into full effect in late 2024, and policymakers may be reluctant to revisit its provisions so soon after implementation. But with the global stablecoin market expanding rapidly and the dollar's digital dominance deepening, the window for Europe to establish a credible euro stablecoin presence may be narrowing.
