Morpho Vault Deposits Surge 51% in Q3 as S&P Global Unveils Vault Risk Framework
TREE NEWS reports: Morpho vaults attracted $2.12 billion in net deposits during the third quarter, a 51% increase that lifted total net deposits to $6.26 billion as of September 30. The growth was fueled by new distribution channels: Robinhood integrated lending vaults into its app, and Circle’s Arc mainnet went live with Morpho running from day one. Together, Robinhood Chain and Arc contributed $670 million in new vault deposits, accounting for 32% of the quarter’s net inflow.
Institutional Backing Meets Regulatory Scrutiny
The surge in deposits has not gone unnoticed by traditional finance. S&P Global announced its Vault Risk Assessment (VRA) framework on October 4, designed to evaluate the actual cash accessibility for vault depositors. The framework scores markets, curator quality, and liquidity, with cash levels and largest depositor concentration directly impacting liquidity scores. Final scores are capped by the weaker of curator and liquidity ratings, and mapped to a scale from AAA(v) to D(v).
This move signals that DeFi lending is being taken seriously by credit rating agencies, but it also exposes structural vulnerabilities. Among 206 vaults with at least $1 million in deposits, the largest wallet held more than 20% of deposits in vaults representing 74% of net deposits. In 8 of the 12 largest vaults, the largest depositor held more than the vault’s cash reserves. Spark and Grove, both deploying Sky’s capital, are the largest depositors in three of these eight vaults.
Concentration and Withdrawal Risks
The concentration of deposits among a few curators and large depositors raises questions about liquidity during stress events. S&P’s framework highlights that even when vaults are backed by similar collateral, withdrawal channels and depositor concentration vary widely. In 217 vaults, 99% of deposits have at least a two-day timelock on risk changes, and 97% are covered by guardian or sentinel mechanisms. While these are viewed as strong governance features, the August 23 attack on Term’s vaults—where attackers used a malicious governance proposal to seize control—shows that governance mechanisms are not foolproof.
Competitive Landscape and Future Outlook
The curator landscape is shifting. The top two curators averaged 61.9% of net vault deposits in Q3, down from 71.0% in Q1 but up from 46.9% a year earlier. Sentora’s share grew to 17.5%, overtaking Gauntlet, while Steakhouse maintained a 43.1% average share. Meanwhile, regulatory questions loom: SEC Commissioner Hester Peirce has raised the issue of when curator discretion makes a vault a security, and Sentora met with the SEC Crypto Task Force in August to discuss this boundary.
As Morpho’s total value locked approaches $11 billion and active loans reach $5.5 billion, the protocol’s integration with traditional finance is accelerating. S&P’s first vault ratings, expected later this year, will provide a benchmark for institutional investors. However, the concentration of deposits and reliance on a few large allocators remain points of fragility. The coming months will test whether DeFi’s promise of transparent, accessible liquidity can withstand the scrutiny of rating agencies and the realities of withdrawal demands under stress.
