ECB and EBA Push Competing Rewrites to MiCA's Stablecoin Architecture

What just happened

The ECB and central banks of all 27 EU member states proposed scrapping the MiCA requirement for stablecoin issuers to keep a portion of their reserves in bank deposits. CryptoSlate reported the proposal directly challenges this mandatory bank deposit safeguard, framing it as an obstacle rather than a protection. Bits.Media confirmed the same: the ECB and national central banks of all 27 EU countries plan to cancel this specific reserve condition written into MiCA.

On a separate track, the European Banking Authority asked the European Commission to study whether crypto lending and loans should come under MiCA. ForkLog reported the EBA called specifically for analysis of cases where crypto companies give clients access to credit DeFi protocols. The potential tools the EBA named include compliance checks for client-facing services, limits on credit leverage, and additional disclosure requirements. The EBA also raised the possibility of a certification system.

DiarioBitcoin adds that the EBA request covers more ground than lending alone: the authority pushed for clearer token classification boundaries, tighter oversight of global stablecoins, and cleaner rules for tokenized deposits – all areas where MiCA's current definitions create ambiguity.

Why it matters

These two proposals cut in opposite directions, and that tension is the core story here. The central bank bloc wants to loosen one of MiCA's most concrete safeguards for stablecoins. The EBA wants to expand MiCA's perimeter into lending and DeFi. Both are responding to the same pressure: MiCA, fully in force since December 2024, is already meeting its limits.

The bank deposit reserve rule was designed to ensure stablecoin liquidity stays anchored in the EU financial system. For issuers of euro-referenced and asset-referenced tokens, this requirement means direct exposure to banking counterparty risk – exactly the risk stablecoin structures are often built to avoid. If the ECB proposal moves forward, issuers could hold reserves in alternative forms. That materially changes the compliance calculation for non-EU stablecoin issuers evaluating whether to seek MiCA authorization. It also shapes how existing EU-authorized exchanges handle stablecoin listings for their retail clients.

The EBA's lending push matters for a different constituency. Any CASP – crypto asset service provider – that wraps DeFi lending protocols for EU retail clients could face new licensing requirements, leverage caps, or mandatory disclosure. Platforms that combine custody with yield or lending products are the most exposed. The EBA's explicit mention of DeFi credit protocol access signals that the regulator is not distinguishing between direct lending and gateway access.

CryptoSlate also flagged that Britain's systemic sterling stablecoin code was simultaneously reaching its consultation deadline. If the UK finalizes a lighter reserve structure while the EU is still debating changes, stablecoin issuers face a clear structural incentive to choose UK domicile for EU-adjacent distribution.

What changes by when

Nothing changes immediately. MiCA's existing rules – CASP licensing, stablecoin authorization requirements, the bank deposit reserve condition – remain in force today. The ECB and national central bank proposal is exactly that: a proposal. It has not been submitted as a formal legislative amendment to the European Parliament or Council. Any change to MiCA's text would require the standard co-decision procedure, which typically runs one to two years from formal proposal to entry into force.

The EBA's call for a crypto lending framework is at an earlier stage still. The EBA asked the European Commission to analyze possible legislative changes – not to draft them. The Commission would need to issue a formal response, potentially commission a study, and then decide whether to initiate a targeted MiCA amendment or wait for a broader review cycle.

What traders and builders should track is not the proposals themselves, but the Commission's response timeline. A formal MiCA review process – if opened – would set the clock for when new lending rules or revised reserve requirements could realistically take effect.

What's still uncertain

The most significant open question is whether the European Commission will treat these two tracks as a coordinated review or as separate inputs with separate timelines. The central bank bloc and the EBA are not aligned. Central banks want to pare back one reserve safeguard; the EBA wants to add new layers in adjacent areas. The Commission holds the formal right of legislative initiative and will need to weigh these positions against each other and against the interests of the European Parliament, which fought for some of MiCA's strictest provisions during negotiation.

Token classification is another unresolved area. DiarioBitcoin reported the EBA's concern about hybrid tokens – instruments that blur the line between asset-referenced tokens, e-money tokens, and utility tokens. MiCA's classification system determines which rulebook applies to a given product. If the EBA succeeds in prompting a classification review, some tokens currently operating under one MiCA category could be recategorized, with immediate compliance consequences.

There is also the question of how much the central bank proposal is driven by concerns about EU competitiveness rather than pure financial stability reasoning. If the answer is competitiveness, the proposal gains political momentum. If it is read as weakening depositor protection, it will face pushback from the same Parliament members who shaped the original reserve requirements.

Our take

For traders on EU-regulated platforms, nothing changes today. The stablecoin reserve requirement stands. The exchange CASP license remains the first thing to verify before depositing or trading – any platform serving EU retail clients with MiCA-regulated tokens must hold one. We recommend checking ESMA's published CASP register directly, not relying on exchange self-reporting.

If you hold or trade significant positions in stablecoins that required MiCA authorization to remain listed, watch the European Commission's legislative calendar. A formal MiCA amendment proposal would signal that the reserve change is moving from discussion to drafting stage. That transition is when authorization strategies for stablecoin issuers actually shift.

For builders working on DeFi lending integrations that serve EU users, the EBA signal is early but directional. We would not wait for final rules before reviewing whether your architecture routes EU retail clients through identifiable credit protocols. The EBA specifically named that pattern as the focus of its analysis. A compliance-aware design now costs less than a retrofit after rules are enacted.

Track three things in parallel: the Commission's response to the EBA lending report, any formal submission of the central bank reserve proposal to the co-decision process, and the UK stablecoin consultation outcome. The gap between UK and EU stablecoin rules is the structural arbitrage that will shape where the next generation of authorized stablecoin issuers chooses to incorporate.

FAQ

Are EU central banks actually removing stablecoin reserve requirements right now?

No. The ECB and central banks of all 27 EU member states have proposed eliminating the mandatory bank deposit portion of stablecoin reserves, but this is a proposal, not an enacted change. MiCA's current reserve requirements remain in force until any legislative amendment completes the EU co-decision procedure.

What does the EBA want to regulate in crypto lending?

The European Banking Authority asked the European Commission to analyze bringing crypto lending and DeFi credit access under MiCA, including cases where crypto companies route clients to credit DeFi protocols. The EBA named potential tools including leverage limits, client compliance checks, and additional disclosure requirements, but no formal rule has been drafted yet.

How does the EBA proposal on hybrid tokens affect existing MiCA-listed assets?

The EBA requested clearer classification boundaries for hybrid tokens – assets that sit across MiCA's existing categories of asset-referenced tokens, e-money tokens, and utility tokens. If the European Commission acts on this, some products currently operating under one MiCA category could be reclassified, changing which set of compliance rules applies to them.
