ECB proposes liquidity thresholds to replace MiCA stablecoin deposit rules
In brief
- ESCB proposes liquidity thresholds for reserve assets maturing within one and five working days, replacing 30-60% bank-deposit rules
- Central banks warn current MiCA rules create direct stablecoin-issuer links, exposing banks to liquidity shocks
- ESCB cites enforcement gaps in MiCA, noting non-compliant crypto firms still access EU customers despite licensing requirements
The Problem With Current Rules
Today's MiCA framework mandates that issuers hold at least 30% of reserves, or 60% for significant stablecoins, as bank deposits. The ESCB argues this concentration creates fragility. If stablecoin holders panic and demand redemptions, issuers must liquidate deposits quickly, forcing banks to absorb sudden outflows they may not be equipped to handle.
A Liquidity-Based Alternative
The central banks propose a different framework. Instead of bank-deposit mandates, the ESCB backed minimum liquidity thresholds for reserve assets maturing within one and five working days.
The European Banking Authority's draft rules, published in 2024, already sketch the contours. For significant stablecoins, the thresholds are 40% of reserves maturing within one working day and 60% within five working days. For non-significant tokens, the thresholds are 20% and 30%, respectively.
The ESCB sees merit in this approach. It separately pointed to overnight reverse repurchase agreements (repos) and short-term sovereign bonds as alternative instruments issuers could use to achieve liquidity. These assets can be mobilized faster than deposits and don't concentrate counterparty risk on a single lender.
Enforcement Gaps Remain
The ESCB also flagged a broader problem. The central banks warned of "material challenges" in enforcing MiCA, saying non-compliant crypto companies can still access EU customers despite licensing requirements. A rule on paper doesn't protect the financial system if bad actors can sidestep it. The proposal, then, sits within a larger conversation about MiCA's teeth—and whether the EU's stablecoin regime can actually enforce what it mandates.
Frequently asked questions
Why do central banks want to change MiCA's stablecoin deposit rules?
The ESCB argues that requiring stablecoins to hold 30-60% of reserves as bank deposits creates a direct link between issuers and lenders, exposing banks to sudden liquidity shocks if a stablecoin run forces rapid withdrawals. Liquidity-based thresholds would distribute risk more evenly.
What would replace the current bank-deposit requirement?
The ESCB proposes minimum liquidity thresholds for reserve assets maturing within one and five working days. For significant stablecoins, this means 40% and 60% respectively; for non-significant ones, 20% and 30%. Repos and short-term sovereign bonds could serve as qualifying instruments.
What enforcement problems does the ESCB see in MiCA?
The central banks warned that non-compliant crypto companies can still access EU customers despite MiCA's licensing regime, creating material challenges for regulators to enforce the rules effectively.
