Circle Challenges EU: Urges Lower Crypto Thresholds in Market Integration Package

Stablecoin giant Circle has issued a formal warning to European regulators, demanding urgent revisions to proposed capitalization rules that could stifle institutional crypto adoption. The company argues the EU's current Market Integration Package framework creates a 'regulatory paradox'—effectively banning euro-denominated stablecoins like EURC from institutional use before they can achieve the massive scale required for legal operation. Circle's petition to the European Commission specifically calls for lowering market cap thresholds for e-money tokens under the Central Securities Depositories Regulation, claiming the existing rules create friction that prevents growth at the very moment Europe seeks deeper financial integration.

The Mechanics of the ‘Chicken-and-Egg’ Problem

The complaint comes down to one mechanical flaw.

Under the current draft of the Central Securities Depositories Regulation, only e-money tokens that already meet a high market capitalization threshold can be used in settlement systems. Circle’s problem with that is straightforward. No euro-denominated EMT currently meets that threshold.

The regulation creates a chicken-and-egg scenario. Tokens need a settlement utility to grow. Settlement utility requires a scale that they cannot achieve without it. Circle is calling it a structural barrier to entry and they are right.

The firm is requesting amendments to the DLT Pilot Regime to break the cycle. Excluding non-significant EMTs from settlement does not protect the market. It stalls the EU’s entire tokenization ambition before it starts.

The stakes are direct. If the European Commission adopts Circle’s recommendation, EURC moves from a niche trading pair to a recognized settlement instrument for traditional finance. Banks and asset managers can settle trades on-chain. Euro stablecoins become functional collateral under CSDR rules.

If nothing changes, institutional participation stays theoretical. The vast majority of stablecoin liquidity sits in USD-denominated assets like USDC. For the EU to build a functioning DLT-based economy it needs a euro equivalent that moves frictionlessly between crypto exchanges and regulated securities venues.

The current framework does the opposite. It locks euro stablecoins out of the infrastructure they need to scale. Circle’s March 20 submission is an attempt to preempt a liquidity freeze in a market that has not even launched yet.

Regulatory Context: MiCA and the Integration Gap

Circle’s lobbying effort comes just months after the Markets in Crypto-Assets (MiCA) regulation took full effect in December 2024. While MiCA provided the licensing framework for issuers, the Market Integration Package is intended to build the rails for those assets to move across borders.

The friction underscores a broader disconnect. While MiCA is law, its implementation has been criticized by legal experts for varying wildly from country to country. Yuriy Brisov, a partner at Digital & Analogue Partners, has argued that the rules remain difficult to interpret, leaving issuers in a gray zone regarding compliance.

The Commission’s proposals are intended to fix this fragmentation, but Circle warns that without specific tweaks to the DLT regime, the “integration” will be in name only. As negotiations on the package continue—potentially through 2027—the gap between regulatory intent and market reality is widening.

If the Commission adjusts the thresholds, Europe opens the door to on-chain capital markets. If they hold the line, euro stablecoins remain stuck in the sandbox. Until the final text is agreed upon, institutional adoption is waiting on a definition.
