BRUSSELS — Stablecoin giant Circle has officially petitioned the European Union to recalibrate its landmark digital asset framework, warning that the current regulatory architecture risks isolating the European market from the rest of the global crypto economy.
In a detailed policy submission to the European Commission, Circle argued that while the Markets in Crypto-Assets Regulation (MiCA) has successfully established Europe as an early regulatory pioneer, its rigid structural mandates have inadvertently excluded the world’s most prominent stablecoins. The issuer of the dollar-pegged USDC and euro-pegged EURC warned that without targeted amendments, the European bloc risks driving liquidity, innovation, and global trading volume toward offshore jurisdictions.
The filing comes at a critical juncture for European crypto policy. As Brussels prepares for a broader legislative review scheduled for 2027, regulators face mounting pressure to balance consumer protection and financial stability with the commercial realities of a borderless digital asset market.
1. Main Facts
At the heart of Circle’s policy intervention is a striking statistic: out of the top 25 stablecoins by global market capitalization, only three are currently regulated under MiCA.
Circle contends that this severe disparity highlights a structural disconnect between European regulatory ambitions and the realities of global liquidity. While MiCA has successfully attracted a cohort of compliant European issuers, it has largely failed to capture the high-volume, globally distributed tokens that anchor modern decentralized finance (DeFi) and centralized exchange trading pairs.
The core of Circle’s remediation proposal focuses on two primary areas:
- Preserving "Multi-Issuance": The firm argues that European regulators must protect structures that allow globally circulating stablecoins to be co-issued by an EU-authorized entity alongside a foreign-regulated counterpart. Eliminating this model, Circle warns, would fragment global supply chains and force European users onto foreign platforms.
- Overhauling Reserve Requirements: Circle has directly challenged MiCA’s strict mandates regarding where and how stablecoin reserves must be stored, arguing that current banking-deposit quotas actively increase systemic credit risk.
2. Chronology of the MiCA Debate and Circle’s Intervention
The journey toward a comprehensive European crypto framework has been long, contentious, and heavily scrutinized by industry participants.
- September 2020: The European Commission initially proposes the Markets in Crypto-Assets (MiCA) regulation as part of a sweeping Digital Finance Strategy designed to foster innovation while mitigating financial crime and consumer risks.
- May 2023: Following extensive negotiations between the European Parliament, the Council, and the Commission, MiCA is formally adopted, establishing clear rules for crypto-asset service providers (CASPs) and stablecoin issuers.
- June 2024–December 2024: Provisions governing stablecoins (categorized under MiCA as Asset-Referenced Tokens and E-Money Tokens) officially take effect. Issuers race to secure European authorization, while international players grapple with compliance hurdles.
- Late 2025: As European crypto firms navigate the tight squeeze of MiCA’s ongoing transition period, European regulators begin tightening enforcement, notably pressing major global exchanges like Binance over compliance issues and "reverse solicitation" exemptions.
- Thursday (Recent Submission): Circle submits its formal response to the European Commission’s ongoing consultation regarding the upcoming MiCA review, marking one of the most significant industry challenges to the framework’s operational rules to date.
- 2027 (Expected): The European Commission is formally set to roll out comprehensive revisions to MiCA, with a specific focus on closing loopholes related to foreign stablecoin issuers and cross-border digital asset activity.
3. Supporting Data and Regulatory Friction Points
Circle’s critique of MiCA is not merely conceptual; it is grounded in specific, highly technical operational constraints that the company claims undermine systemic stability rather than protect it.
The Commercial Bank Deposit Mandate
Under current MiCA rules, e-money token issuers are legally required to hold at least 30% of their reserve assets in commercial bank deposits. For tokens deemed "significant" due to their massive market penetration, this threshold climbs to a staggering 60%.
Circle has pushed back hard against this requirement, arguing that parking billions of dollars in commercial bank deposits introduces unnecessary counterparty credit risk. Instead of shielding token holders from volatility, Circle argues, the rule exposes reserve funds to the vulnerability of commercial banking institutions. Intriguingly, this puts Circle in rare alignment with the European Central Bank (ECB), which has previously voiced skepticism over traditional banking exposure for digital asset reserves and has called for more flexible, ultra-liquid alternatives.
Single-Sovereign and Single-Bank Concentration Caps
In addition to the commercial deposit quotas, Circle took aim at two specific regulatory caps:
- A 35% cap on single-sovereign exposure, which restricts the amount of low-risk government debt (such as short-term sovereign bonds) an issuer can hold.
- Strict limits on how much capital can be held at any single banking institution.
Circle argues that these constraints create an operational nightmare for large-scale issuers. Rather than mitigating risk, the rules force major stablecoin operators to fragment their reserves across dozens of different commercial banks, dramatically increasing administrative overhead, monitoring costs, and overall operational vulnerability.
4. Official Responses and Industry Stakeholder Reactions
The debate over MiCA’s shortcomings has triggered a wide array of responses from regulators, lawmakers, and competing market participants.
- Circle’s Official Stance: In its official commentary, Circle emphasized that its recommendations are intended to refine, rather than dismantle, a framework it otherwise praises. "MiCA gave Europe an early lead in regulatory clarity," a company representative noted, "but regulation must scale with reality. If the world’s biggest tokens remain outside the perimeter, the framework risks creating a localized sandbox rather than a globally competitive market."
- The European Commission’s Position: Brussels officials have maintained a pragmatic stance, acknowledging that MiCA is a living framework designed to evolve. The Commission’s decision to open a formal consultation and target 2027 for major revisions indicates a willingness to listen to industry feedback, particularly as global stablecoin dynamics shift.
- The ECB and Prudential Regulators: Central bankers across the Eurozone continue to eye stablecoins with cautious vigilance. While the ECB shares Circle’s concerns regarding commercial bank deposit risks, it remains deeply opposed to any regulatory relaxation that might dilute monetary sovereignty or encourage the widespread substitution of domestic fiat deposits with private, dollar-pegged digital assets.
5. Global Implications and the Geopolitical Stablecoin War
Circle’s lobbying efforts in Brussels cannot be viewed in a vacuum. They are part of a massive, high-stakes geopolitical contest over monetary dominance and the future architecture of global payments.
As U.S. lawmakers increasingly debate federal stablecoin legislation, Washington has begun framing dollar-pegged tokens explicitly as a strategic tool to extend the global dominance of the U.S. dollar (the greenback). By anchoring international trade, cross-border remittances, and emerging decentralized financial systems in dollar-backed stablecoins, the United States stands to reinforce its central role in the global financial architecture.
Conversely, European policymakers have long harbored anxieties regarding "dollarization"—the risk that citizens and businesses across the EU might bypass the euro in favor of more liquid, globally accessible dollar stablecoins. This underlying tension explains why MiCA’s rules on foreign issuers and reserve structures were drafted with such stringent defensive barriers in mind.
However, industry analysts warn that overly defensive regulations may backfire. By making compliance excessively burdensome or structurally incompatible with global liquidity pools, Europe risks marginalizing its own financial institutions. Local crypto firms may find themselves unable to compete with offshore alternatives that operate free of MiCA’s restrictive reserve quotas.
As the European Commission digests Circle’s recommendations and prepares for the 2027 legislative overhaul, the bloc faces a definitive choice: adapt its regulatory perimeter to capture and tame global stablecoin liquidity, or maintain a fortress-like stance that leaves the world’s most vital digital financial plumbing entirely outside of Europe’s reach.
