Briefing
The European Banking Authority (EBA) issued two Opinions formally rejecting the European Commission’s (EC) proposed amendments to the draft Regulatory Technical Standards (RTS) under the Markets in Crypto-Assets Regulation (MiCA) concerning stablecoin reserve liquidity and composition. This intervention maintains the EBA’s original, highly conservative prudential framework for Asset-Referenced Tokens (ARTs) and E-Money Tokens (EMTs), which is architecturally aligned with traditional banking liquidity standards. The EBA explicitly cited that the EC’s proposed changes ∞ which included allowing non-highly liquid financial instruments and relaxing concentration limits ∞ would introduce material liquidity risk and open the door to regulatory arbitrage, thus compromising the financial stability objectives of the MiCA framework, the full application of which begins in 2024 and 2025.

Context
Prior to this EBA action, the regulatory landscape for stablecoin reserves was characterized by the EC’s attempt to introduce greater flexibility into the final technical standards, specifically by modifying the EBA’s initial, more stringent draft RTS. The prevailing challenge for the industry was navigating the final, detailed requirements for reserve asset composition, which directly dictates capital efficiency and product structuring for issuers. The EC’s proposed amendments represented a potential, albeit controversial, easing of the reserve rules, suggesting a path for stablecoin issuers to include assets like certain money market funds or even non-highly liquid financial instruments (non-HLFI) in their backing portfolios, which the EBA viewed as a direct deviation from the core MiCA prudential mandate.

Analysis
This EBA Opinion directly impacts the compliance frameworks of all prospective ART and EMT issuers in the EU by cementing a strict, conservative interpretation of reserve asset eligibility. Regulated entities must now proceed with the EBA’s original, more stringent RTS as the operative standard, which mandates that reserve assets must be highly liquid and carry minimal market, credit, and concentration risk. This forces issuers to structure their product reserves almost exclusively with sovereign debt and high-quality, short-term money market instruments, directly affecting capital allocation and yield potential.
The compliance function must update its risk mitigation controls to ensure reserve portfolio management adheres to the strict concentration and look-through limits that the EBA is defending, thereby reducing the operational risk of a stablecoin run. This action reinforces the principle that digital asset stability must be achieved by leveraging time-tested banking liquidity safeguards.

Parameters
- EC Proposed Change ∞ Allowing investment into non-highly liquid financial instruments (non-HLFI), which the EBA rejected.
- Primary Risk Cited ∞ Material liquidity risk and potential for regulatory arbitrage, which the EBA seeks to prevent.
- EBA Action Type ∞ Two formal Opinions issued in response to the European Commission’s proposed amendments.
- Affected Tokens ∞ Asset-Referenced Tokens (ARTs) and E-Money Tokens (EMTs) under the MiCA framework.

Outlook
The next phase of this process requires the European Commission to issue its final decision on the RTS, which will either override the EBA’s opinion with a reasoned justification or align with the EBA’s stricter stance. Given the EBA’s strong financial stability mandate, the EC faces significant political and legal pressure to adopt the more conservative approach. This regulatory friction sets a powerful precedent for how EU financial authorities will enforce the prudential perimeter of MiCA, signaling a clear prioritization of systemic risk mitigation over market flexibility. Globally, this EBA stance will be studied by other jurisdictions, such as the US and UK, as a template for establishing non-bank stablecoin reserve requirements, potentially leading to a more harmonized, yet highly conservative, global standard for payment stablecoins.
