Briefing
The European Banking Authority (EBA) issued two Opinions rejecting the European Commission’s (EC) proposed amendments to the draft Regulatory Technical Standards (RTS) on the Markets in Crypto-Assets Regulation (MiCA) reserve requirements. This action immediately solidifies a stricter prudential framework for stablecoin issuers by preventing the introduction of material liquidity risk and regulatory arbitrage. The EBA specifically deemed the EC’s changes inconsistent with Articles 36(1)(b) and 38(1) of MiCA, thereby maintaining a tighter alignment with the established banking liquidity standards.

Context
Prior to this intervention, the operationalization of MiCA’s stablecoin framework was subject to a period of technical uncertainty as the EC sought to amend the EBA’s initial draft RTS. The prevailing challenge was the potential for the EC’s proposed changes to permit the investment of issuance proceeds into non-Highly Liquid Financial Instruments (non-HLFI) and to relax crucial concentration and look-through limits. This regulatory ambiguity created a compliance risk for Asset-Referenced Token (ART) and E-Money Token (EMT) issuers, who faced the possibility of a less robust, more market-exposed reserve architecture.

Analysis
This EBA decision mandates that stablecoin issuers, specifically ART and EMT providers, must maintain a conservative reserve architecture fully aligned with the EBA’s original, more stringent standards. The impact directly alters the capital and treasury management systems of regulated entities, preventing the use of instruments that could introduce credit or concentration risk into the reserve. For a firm, this means the compliance framework must strictly prohibit the investment of reserve assets into non-HLFI, ensuring the 1:1 backing remains highly liquid and minimally exposed to market volatility. This is a critical update because it closes a potential loophole for regulatory arbitrage, forcing systemic compliance with banking-grade prudential requirements.

Parameters
- MiCA Articles Reinforced ∞ Articles 36(1)(b) and 38(1). (These are the specific legal provisions the EBA cited as being violated by the EC’s proposed amendments, relating to the reserve of assets.)
- Core Risk Mitigated ∞ Material Liquidity Risk. (The primary risk the EBA sought to prevent by rejecting the EC’s amendments.)
- Reserve Requirement Ratio ∞ 1:1. (The fundamental backing ratio for stablecoins under MiCA.)
- EC Letter Date ∞ August 28, 2025. (The date the EC informed the EBA of its intention to endorse the RTS with amendments.)

Outlook
The EBA’s firm stance ensures the MiCA stablecoin framework will proceed with a high degree of prudential rigor, setting a precedent for banking-style reserve management in digital assets. The next phase involves the EC’s formal response to the EBA’s Opinions, though the EBA has clearly signaled its commitment to close scrutiny of the MiCA prudential framework. This action will likely influence global regulators, including the Financial Stability Board (FSB), who are seeking to establish comprehensive and consistent rules for stablecoins, positioning the EU framework as the gold standard for reserve quality.

Verdict
The EBA’s decisive rejection of relaxed standards affirms the EU’s commitment to a banking-grade prudential framework for stablecoins, structurally reinforcing MiCA’s role as a global benchmark for digital asset financial stability.
