Circle, the issuer of the world's second-largest stablecoin by market capitalization, has formally called on the European Union to overhaul the reserve requirements embedded in the Markets in Crypto-Assets (MiCA) regulation — a move that could reshape how stablecoin operators access and manage capital across the bloc. The company wants mandatory bank-deposit minimums scrapped in favor of more flexible liquidity standards, while simultaneously pressing Brussels to protect the right of stablecoin issuers to operate across EU member-state borders without additional regulatory friction.
The intervention arrives at a critical juncture. MiCA, which entered full force as the world's most comprehensive crypto regulatory framework, was designed to bring stability and consumer protection to digital asset markets. Its reserve rules for stablecoin issuers — requiring that a significant portion of reserves be held in bank deposits — were intended to anchor the sector to the traditional financial system and limit systemic risk. Circle's argument, however, is that those same rules may be creating operational rigidities that undermine rather than reinforce financial stability, particularly for non-bank issuers whose reserve management disciplines already meet high liquidity standards through other instruments.
The Reserve Architecture Debate
At the heart of Circle's submission is a structural critique of MiCA's prescriptive approach to reserves. The regulation, as currently written, mandates that a defined minimum share of stablecoin reserves be placed in bank deposits — an architecture that effectively ties issuers to banking counterparties in ways that introduce their own concentration and counterparty risks. Circle is advocating for a principles-based liquidity framework instead, one that would permit issuers to hold qualifying liquid assets — such as short-duration government securities — as an alternative or complement to bank deposits, provided those assets meet rigorous liquidity and credit-quality thresholds.
This is not a purely self-interested argument, though Circle's commercial position gives it obvious incentive to pursue change. The core regulatory-design tension is real: by compelling issuers to concentrate reserves in bank deposits, MiCA may inadvertently replicate the very fragility it seeks to prevent. Bank deposits, unlike short-term sovereign instruments, carry credit exposure to individual institutions and are subject to bail-in regimes. A framework that instead specifies liquidity outcomes — rapid convertibility, minimal credit risk, transparent valuation — without dictating the exact instruments used could arguably deliver superior systemic resilience while giving issuers room to optimize.
Cross-Border Issuance: A Single-Market Imperative
Circle's second major concern centers on cross-border stablecoin issuance within the EU. The single market has long been one of Europe's defining economic achievements, and its extension to digital finance is a stated ambition of MiCA itself. Yet the company warns that without clear and consistently applied rules governing cross-border activity, the regulation risks fragmenting rather than integrating the European stablecoin market. Divergent national-level interpretations of MiCA's passporting provisions could, in practice, force issuers to seek separate authorizations or comply with overlapping supervisory demands across member states — an outcome at odds with the regulation's pan-European intent.
Preserving robust cross-border issuance rights matters not just for Circle's own growth ambitions in Europe, but for the broader competitive positioning of EU-regulated stablecoins against dollar-denominated alternatives that face no comparable fragmentation risk. If European issuers are forced to navigate a patchwork of national requirements, the structural advantage of a MiCA license — theoretically granting access to all 27 member states from a single authorization — is materially eroded.
The Timing and Political Context
Circle's push comes as the European Commission prepares for its formal MiCA review process, a scheduled reassessment that will give policymakers the opportunity to refine the regulation based on early implementation experience. This review window is politically significant: it represents perhaps the only near-term opportunity for substantive amendments before MiCA's requirements become entrenched through years of supervisory practice and national-level jurisprudence.
The stablecoin industry globally is watching closely. Other major issuers and their lobby groups are likely to coordinate parallel submissions, and the outcome of the MiCA review could set a global precedent for how sovereign regulatory regimes treat reserve composition and cross-border digital-asset activity. The European Banking Authority (EBA) and the European Securities and Markets Authority (ESMA), both of which hold supervisory roles under MiCA, will be central to how any revised framework is interpreted and enforced.
What This Means for the Market
Circle's advocacy represents more than a compliance adjustment request — it is a direct challenge to the philosophical underpinnings of MiCA's stablecoin chapter. If Brussels accedes to more flexible liquidity rules, it would validate the argument that principles-based regulation can coexist with robust consumer protection in digital finance. If it holds firm on bank-deposit minimums, issuers will face continued pressure to maintain banking relationships as a regulatory prerequisite, concentrating systemic dependencies in precisely the counterparties regulators most fear. For European policymakers, the review is an opportunity to demonstrate that MiCA can evolve with the market it governs — rather than calcify into a framework that advantages incumbents and discourages innovation at precisely the moment when the global race for stablecoin leadership is intensifying.
