SKN | ECB Pushes to Extend Stablecoin Yield Ban to Lending and Staking

Key Points:

• The European Central Bank and EU national central banks want MiCA restrictions on stablecoin remuneration extended to lending, borrowing, staking and other structures that can generate indirect returns.
• The ESCB argues that yield-bearing arrangements could blur the distinction between electronic money and bank deposits, potentially changing competition across the European financial system.
• Central banks also want to replace MiCA’s 30% to 60% bank-deposit reserve requirement with liquidity rules based on how quickly stablecoin reserves can be converted into cash.

European central banks are seeking tighter restrictions on how stablecoins can generate returns, expanding a regulatory debate that increasingly connects crypto markets with conventional banking. In its response to the European Commission’s review of the Markets in Crypto-Assets Regulation, the European System of Central Banks said the existing prohibition on direct stablecoin remuneration should also cover lending, borrowing, staking and other indirect structures.

Central Banks Target Indirect Stablecoin Yield

The ESCB, comprising the ECB and the EU’s 27 national central banks, said stablecoins are intended primarily for payments rather than savings. Its 57-page consultation response supports maintaining the MiCA prohibition on crypto-asset service providers paying remuneration on stablecoins, but argues that the restriction should extend beyond activities already governed by the regulation.

The concern is that platforms could potentially transform a non-yielding stablecoin into a yield-bearing arrangement through lending, staking or layered financial products. From the central banks’ perspective, such structures could replicate some economic characteristics of bank deposits while operating under a different regulatory framework. The proposal therefore focuses on the economic function of the product rather than only the form in which the return is delivered.

Reserve Rules Could Also Change

The ESCB is simultaneously proposing a significant adjustment to stablecoin reserve requirements. Under current MiCA rules, issuers must hold at least 30% of reserves as bank deposits, rising to 60% for stablecoins classified as significant. The central banks argue that large stablecoin deposits could create a less stable source of bank funding because issuers may withdraw funds rapidly during periods of market stress.

Instead, the ESCB wants reserve requirements tied to liquidity maturity. Its proposal would require specified portions of reserves to mature within one to five working days. Draft European Banking Authority standards cited by CoinDesk provide a possible framework: significant stablecoins would hold at least 40% of reserves in assets maturing within one day and 60% within five working days, while non-significant stablecoins would face lower thresholds of 20% and 30%.

Implications for Crypto Lending and Staking

The proposed expansion could affect a broad segment of the European crypto market because stablecoins are increasingly used as collateral, settlement assets and liquidity instruments. Restricting indirect remuneration could reduce the range of stablecoin-based financial products available to European customers, particularly if lending or staking arrangements are viewed as attempts to circumvent the direct-yield prohibition.

For crypto platforms, the regulatory distinction could become increasingly important. Businesses offering stablecoin lending or rewards may need to demonstrate that their products do not effectively transform payment tokens into deposit-like savings products. The approach could also influence how global platforms structure products specifically for EU customers.

Europe’s Approach Fits a Wider Stablecoin Debate

The European discussion follows similar debates elsewhere. In the United States, eight banking groups urged lawmakers to strengthen restrictions on stablecoin rewards during the Senate debate over the Clarity Act. That legislation subsequently failed to advance in a 49-50 procedural vote, leaving the U.S. framework unresolved at the statutory level.

At the same time, the ESCB said European regulators face enforcement challenges because some non-compliant crypto businesses continue serving EU customers despite the MiCA licensing deadline in June 2026.

The next stage will depend on how the European Commission incorporates the central banks’ recommendations into the MiCA review. For crypto investors and institutions, the key variables are whether indirect stablecoin yield becomes more restricted, how reserve-liquidity rules are ultimately designed, and whether enforcement becomes more consistent across the bloc. The outcome could materially shape the economics of stablecoin lending, staking and payments across Europe.
