Circle, the company behind the world's second-largest stablecoin by market capitalization, has launched a formal lobbying push against one of the most contentious provisions in the European Union's digital asset framework — the requirement that stablecoin issuers park a significant portion of their reserves in bank deposits. The move puts Circle on a direct collision course with European central banks, which are simultaneously calling for tighter safeguards, and frames what may become the defining regulatory battleground for dollar-denominated stablecoins seeking a durable foothold on the continent.
The core of Circle's argument is structural. Under the EU's Markets in Crypto-Assets (MiCA) regulation, issuers of asset-referenced tokens and electronic money tokens — the two categories that capture most mainstream stablecoins — must hold a defined share of their reserve assets in deposits at licensed credit institutions. Circle contends that this mandate creates unnecessary concentration risk and places stablecoin operators under an asymmetric dependency on the traditional banking sector, the very counterparty risk that robust reserve design is supposed to minimize. The company is urging EU policymakers to replace the bank-deposit floor with a broader, more flexible reserve framework that could include high-quality liquid assets such as short-duration government securities.
This is not a fringe concern. The tension between stablecoin reserve architecture and banking regulation sits at the heart of how dollar-pegged instruments interact with existing monetary infrastructure. When Silicon Valley Bank collapsed in March 2023, Circle itself disclosed that roughly $3.3 billion of USDC's reserves were held at the failed institution, triggering a brief but sharp depeg. That episode demonstrated, in real time, the systemic exposure that bank-deposit mandates introduce — an irony that Circle is now actively leveraging in its EU advocacy. Requiring issuers to concentrate reserves inside the very institutions that carry deposit-run risk does not obviously make stablecoin holders safer; it transfers and potentially amplifies the risk profile.
Beyond the reserve question, Circle is pressing on two additional fronts that together would reshape the operational landscape for non-European stablecoin issuers. First, the company is advocating for the preservation of cross-border co-issuance arrangements — structures that allow a stablecoin to be issued and redeemed across multiple legal jurisdictions through coordinated entity frameworks, rather than requiring a separate, standalone issuer in every market. Co-issuance is commercially important: it allows Circle to maintain liquidity efficiency and a unified reserve pool rather than fragmenting capital across dozens of national subsidiaries. MiCA's current architecture creates ambiguity around whether such arrangements remain permissible at scale, and Circle wants explicit regulatory endorsement.
Second, and perhaps most significant from a geopolitical standpoint, Circle is calling on the EU to establish a formal recognition route for foreign stablecoin issuers. Without such a pathway, non-EU operators — including those regulated under frameworks like the United States' emerging federal stablecoin regime or the United Kingdom's evolving Payment Services rules — face a binary choice: either establish a full MiCA-compliant entity inside the EU or exit the European market entirely. A recognition or equivalence mechanism, similar in concept to what exists in traditional financial regulation for foreign banks and investment firms, would allow issuers regulated to comparable standards abroad to serve EU users without duplicating their entire compliance infrastructure. This matters most for USDC, which competes for European institutional and retail volume against Tether's USDT — an issuer that has chosen not to pursue MiCA authorization at all.
The response from European central banking authorities has been predictably cautious. Central banks are pushing for stronger safeguards rather than looser reserve requirements, reflecting longstanding concerns about the systemic implications of widely adopted private stablecoins. Their worry is less about Circle specifically and more about the precedent: if a stablecoin at scale holds its reserves primarily in sovereign debt rather than bank deposits, the instrument begins to behave more like a money market fund than an electronic payment token, raising questions about monetary transmission, financial stability, and the appropriate regulatory perimeter. That is a legitimate debate, but it is also one that risks producing rules optimized for theoretical worst cases rather than the operational realities facing compliant issuers today.
What this moment reveals is that MiCA, for all its ambition as a comprehensive crypto regulatory framework, is already entering a phase of consequential refinement before its stablecoin provisions have been fully stress-tested by the market. Circle's intervention is a sophisticated attempt to shape that refinement in ways that favor reserve flexibility, global interoperability, and competitive parity with less-regulated rivals. Whether EU policymakers respond by accommodating compliant foreign issuers or by hardening domestic requirements will determine whether the eurozone becomes a genuine hub for regulated stablecoin activity — or cedes that ground to jurisdictions moving faster and with lighter hands.
