EU Considers MiCA Oversight for DeFi Lending Vaults

Brussels Opens the Door on DeFi Lending

The European Commission opened a consultation on May 20, 2026, seeking input on areas MiCA left unresolved when it first passed. DeFi lending and crypto borrowing sit at the center of that conversation. The consultation window closes on September 30.

MiCA was built to standardize crypto asset rules across the EU, but it never fully addressed on-chain lending models. Lending vaults in particular present a classification problem regulators still haven’t solved.

Where MiCA Left Vaults Undefined

Lending vaults channel large pools of assets into credit markets, often without the characteristics regulators typically associate with traditional lenders. Their legal status has rested on non-binding interpretations for years now, leaving open questions about who is actually responsible when something goes wrong.

Yuriy Brisov, a partner at Digital & Analogue Partners, points out that EU law doesn’t have a specific category for a “vault” at all. That means lawyers have to analyze what a structure actually does and who controls it, rather than relying on how it’s labeled. This kind of functional analysis is becoming central to how regulators will eventually decide.

Three Different Paths Forward

Industry voices are offering distinct, sometimes conflicting, ideas for how Brussels should approach this.

• Look at structural facts, not labels. Brisov suggests regulators focus on specific structural elements, like whether there’s an undertaking or appointed manager at all. He also points to direct coded claims on the pool for token holders, and whether users can exit before parameter changes take effect, as key signals worth examining.
• Don’t use decentralization as the test. Jonathan Galea, a partner at Cahill Gordon & Reindel, warns that treating decentralization itself as the dividing line could backfire. It risks penalizing newer, more innovative protocols while giving mature incumbents an easier path to compliance.
• Give DeFi lending its own rulebook. Michael Egorov, founder of Curve Finance, argues DeFi lending needs a framework built specifically for it, with different safeguards than traditional lending. He believes a tailored approach would actually improve both safety and accessibility.

Why a Single Category Worries Everyone

A recurring concern among stakeholders is Brussels applying one blanket rule to something that isn’t uniform. Galea makes the point that vaults serve very different functions. Some direct liquidity straight into lending markets, while others buy and sell crypto assets entirely.

Lumping DeFi lending into a single regulatory category risks capturing fundamentally different activities under the same rules. That kind of mismatch could produce regulation that fits none of them well, and the uncertainty in the meantime is already affecting how protocols get designed and how users assess their own risk.

Where Different Voices Stand

After September 30

Once the consultation period closes, the feedback collected will shape whatever comes next. Regulators will need to decide whether lending vaults stay outside MiCA entirely, or whether a tailored framework for crypto lending and borrowing gets built from scratch.

Builders and users alike should watch closely for which criteria regulators end up prioritizing, whether that’s structural control, responsibility allocation, or user exit rights. The real challenge for Brussels is finding a way to distinguish between genuinely different forms of on-chain lending, rather than treating them as one problem with one solution.

Hashlytics Take

The interesting tension here isn’t whether the EU regulates DeFi lending. It’s whether regulators can resist the urge to write one rule for a category that clearly doesn’t behave like one thing. Brisov’s functional test, looking at control and structure rather than labels, is the only approach on the table that scales past the current wave of vaults. Everything else risks either freezing innovation in place or missing the actual risk entirely.
