Coin Metrics finds stablecoin lending often trails 1-year Treasuries despite $290 billion market
A Coin Metrics research note compared on-chain fixed-income opportunities with U.S. Treasuries and volatile crypto assets, arguing that stablecoin lending does not consistently deliver a superior risk premium despite the sector’s scale. The report says the stablecoin market has grown past $290 billion, with more than $8.6 billion deposited in lending protocols such as Aave v3 and Morpho. Yet returns vary sharply even for the same asset: since January 2026, average USDC deposit yields on Aave and Morpho have differed by 159 basis points. On Aave, USDC lending yields averaged 31 basis points below the 1-year Treasury yield, and stayed below that benchmark 78% of the time in 2026. Morpho v2 vaults posted a median USDC return 65 basis points above the 1-year Treasury yield, but with roughly 3.3 times the annual volatility. The report also highlights dispersion within the same protocol, governance-driven yield differences, and the role of vault curators and yield-bearing stablecoins such as USDS and GHO. While stablecoins do not always beat traditional fixed-income alternatives, Coin Metrics says they have delivered a steadier income source than lending volatile assets like ETH or WBTC.
