European Commission considers regulating DeFi lending vaults

The European Commission has launched a consultation to determine whether decentralized finance (DeFi) lending and borrowing activities should be brought under the Markets in Crypto Assets (MiCA) regulatory framework. While the original MiCA legislation largely excluded these activities, Brussels is now examining how to regulate digital asset lending, with a specific focus on lending vaults.

Lending vaults present a significant regulatory challenge because they can automate the distribution of capital across various markets via software and smart contracts. Unlike traditional banks or centralized exchanges, these systems often lack a single responsible entity. Responsibilities—such as risk management, strategy, and capital allocation—are frequently distributed among multiple participants or automated protocols.

Legal experts note that EU law currently lacks a specific category for ‘vaults,’ meaning regulators must define them by their economic function rather than their label. This creates difficulty in establishing a regulatory perimeter, as DeFi projects often transition from centralized control by developers to more decentralized structures over time. The complexity is illustrated by protocols like Morpho, whose architecture divides roles among owners, curators, allocators, and sentinels, making it difficult to map onto existing legal models.
