Aave Founder Stani Kulechov Slams ECB and EBA for Pushing Stablecoin Yield Ban

Stani Kulechov, founder of Aave (AAVE), on Friday criticized the European Central Bank and the European Banking Authority over their positions in the MiCA regulatory consultation, calling both institutions out for pushing a stablecoin yield ban and restrictions on DeFi access.

Key Points

Aave founder Stani Kulechov publicly criticized the ECB and EBA responses to the MiCA consultation.
Both institutions advocated for prohibiting yield payments on stablecoins, per Kulechov’s account.
They also pushed for restrictions on crypto asset service providers offering DeFi access.
The positions would affect any European CASP that routes users to DeFi protocols.
Kulechov described the responses as a source of disappointment, not just disagreement.

Kulechov said in a post that the ECB and EBA are not only advocating for a prohibition on paying yield on stablecoins but also for restrictions on crypto asset service providers that give users access to DeFi, including protocols within the Aave ecosystem.

What The ECB And EBA Are Advocating

Kulechov’s post broke down two distinct positions from the regulators.

The first is a yield prohibition on stablecoins. Under this position, issuers or intermediaries would be blocked from passing interest or yield to stablecoin holders. The rationale used by European banking regulators is that yield-bearing stablecoins compete directly with bank deposits and could draw funding away from the traditional banking system.

The second position would restrict CASPs, the licensed intermediaries under MiCA, from providing their users with access to DeFi protocols. This would effectively wall off European retail users from permissionless lending, liquidity, and yield products if their access point is a licensed CASP.

For Aave specifically, this matters at two levels. At the protocol level, Aave is a primary destination for users seeking yield on stablecoin holdings. At the infrastructure level, many users access Aave through interfaces operated by licensed firms. A CASP restriction could choke that distribution channel even if the Aave protocol itself remains accessible.

Background On MiCA And Stablecoin Regulation

MiCA, the Markets in Crypto-Assets regulation, took effect in the European Union in 2024 and established a licensing framework for crypto asset service providers and stablecoin issuers. The regulation left several technical details to be filled in through consultations, delegated acts, and guidance from the EBA and other bodies.

The stablecoin yield question has been contested since before MiCA passed. Banking lobby groups consistently argued that yield-bearing stablecoins are deposit-like instruments and should be treated as such. DeFi advocates countered that smart-contract yield is structurally different from interest on a bank deposit.

Kulechov’s post came in response to what he described as formal consultation responses, meaning these are not casual opinions but official positions submitted to the MiCA process. That distinction matters. Informal commentary from a central bank official can be walked back. A formal consultation response carries weight in how delegated acts are eventually drafted.
What This Means for DeFi in Europe

If the ECB and EBA positions are adopted, the practical effect on European DeFi users would be significant. Licensed CASPs, the only compliant on-ramps for many retail users, could be prohibited from routing transactions to protocols like Aave, Uniswap (UNI), or any permissionless platform.

The yield prohibition would hit stablecoin issuers operating in the EU. Products like yield-bearing USD Coin (USDC) or similar instruments could become unavailable through regulated European channels even if they remain accessible globally.

Kulechov’s public statement is a form of industry pushback designed to create visibility during the consultation window. DeFi protocols cannot submit formal consultation responses as legal entities in the way banks can. Public posts by founders are one of the few levers available to the sector.

The consultation is ongoing. Final positions from the EBA and delegated act drafting by the European Commission will determine whether these regulatory preferences become binding rules.
