S&P Global Ratings launched a risk assessment framework for digital asset lending vaults, products that pool investor deposits for yield-generating strategies. On-chain lending vaults have expanded significantly, with deposits reaching approximately $10 billion in September, up from $1.5 billion two years prior.
The framework evaluates vaults across six distinct risk categories: portfolio credit quality, liquidity mismatch, curator, blockchain, protocol, and vault security and governance risk. S&P Global clarified that the framework does not constitute credit ratings and does not evaluate vault yields. Instead, it aims to identify potential points of failure across the risk landscape.
Lisa Schroeer, an analyst at S&P Global Ratings, said a material weakness in any single factor can constrain the overall Vault Risk Assessment. She added that a strong score in one factor does not offset a material weakness in another, reflecting a sector with many potential points of failure.
Digital asset lending vaults typically pool investor capital and deploy it through predefined strategies managed either by smart contracts or human curators. Depositors receive tokens representing their share of the vault's assets and accrued returns.
The expansion has been driven by exchanges, wallets and DeFi platforms rolling out products that package lending and other yield strategies for users. These offerings span various assets, from core cryptocurrencies to tokenized securities.
In February, Wallet in Telegram, now known as Walt, introduced self-custodial vaults for Bitcoin, Ethereum and USDT utilizing infrastructure from Morpho, TAC and Re7. Kraken followed with its own Bitcoin yield vault in May, powered by Veda and curated by Sentora. The product attracted $30 million in deposits from 4,000 wallets within its initial 10 hours.
By September, Kraken expanded to yield vaults for tokenized traditional securities, including tokenized Nvidia shares, SPDR S&P 500 ETFs and Invesco QQQ ETFs, with Sentora managing lending strategies through DeFi markets.
The sector's growth has also exposed risks. In August, the lending protocol Term Finance experienced an estimated $8.5 million loss when an attacker exploited governance controls within its Meta Vaults.
Schroeer said the assessment aims to provide greater transparency on risks involved, allowing entities to make more informed decisions when allocating capital to DeFi vaults. Digital asset lending vaults currently operate within a regulatory gray area in the United States.
