Key takeaways
- Crypto lending vault deposits jumped roughly 150% to $10 billion
- SEC and European scrutiny raises questions about vault curators
- S&P Global introduced new assessments of onchain lending risks
Crypto lending vaults have attracted more than $10 billion in deposits, up from approximately $4 billion at the beginning of 2025, as investors increasingly use decentralized finance (DeFi) platforms to earn returns on stablecoins and other digital assets.
The roughly 150% expansion has drawn attention to the managers controlling lending strategies, with the US Securities and Exchange Commission (SEC) and European regulators examining how existing financial rules apply to these structures. The Financial Times reported the latest developments on October 19, highlighting annual yields ranging from 3% to more than 20% across different strategies.
Crypto Lending Vaults Attract $10 Billion as Yields Reach 20%
Unlike traditional lending pools, many crypto vaults rely on specialized managers known as curators. These operators select lending markets, establish collateral requirements, adjust risk parameters and allocate deposited funds across borrowing strategies.
Investors deposit assets such as USDC or USDT and receive tokens representing their interests in the vault. Returns generally come from borrowers paying interest, although some strategies involve additional incentives or more complex exposures.
The expansion is particularly notable as established crypto companies increasingly integrate decentralized lending infrastructure. Coinbase, for example, has expanded its onchain lending services using Morpho, while its newer fixed-rate loans introduce different borrowing arrangements.
Institutional involvement is also growing. Flare previously integrated FXRP into a $280 million RLUSD lending vault operated through Morpho, demonstrating how XRP-backed collateral can connect with Ethereum-based credit markets.
However, attractive yields do not necessarily indicate low risk. Borrowers may provide volatile collateral, while complicated liquidation mechanisms can amplify losses during sudden market declines.
SEC and European Regulators Examine DeFi Lending Risks
Regulatory attention increasingly centers on whether vault curators perform functions resembling traditional investment managers.
In a July statement, SEC Commissioner Hester Peirce warned that certain crypto activities may fall under existing securities laws regardless of the technology involved. The comments did not establish that all lending vaults are securities products, but reinforced the importance of evaluating individual structures.
European authorities have also identified risks involving collateral chains, liquidity and cascading liquidations in decentralized lending. Those concerns become more important when multiple protocols depend on the same assets or interconnected borrowing positions.
Past failures illustrate the potential consequences. The Elixir stablecoin collapse exposed financial connections involving multiple DeFi platforms, while earlier market liquidations showed how falling crypto prices can quickly force leveraged positions to close.
S&P Global Introduces Vault Risk Assessments
The regulatory discussion coincides with a significant development in institutional crypto infrastructure.
On October 4, S&P Global Ratings launched a dedicated assessment framework for digital asset lending vaults. Its methodology evaluates six areas: portfolio credit quality, liquidity mismatch, curator risk, blockchain risk, protocol risk, and vault security and governance.
S&P emphasized that these assessments are not conventional credit ratings and do not evaluate advertised yields.
The initiative reflects growing demand for standardized risk information as DeFi increasingly resembles traditional managed investment products. Institutional interest is already extending across crypto lending markets, including the broader Sky ecosystem.
