The Federal Reserve raised its target range to 3.75%-4.00% on September 16, pushing the one-year Treasury yield to 4.45% the same day. That benchmark now sets a fresh standard against which crypto lending yields must be measured.
Coin Metrics found that USDC lenders on Aave earned an average of 31 basis points less than the one-year Treasury rate during its studied period in 2026. Aave's yield fell short of the Treasury rate in 78% of the intervals measured across that window.
Other platforms showed different results. Morpho's median USDC vault beat the Treasury benchmark by 65 basis points on average, but carried roughly 3.3 times the annualized volatility of Aave's offering.
Two Benchmarks, Not One
Comparing crypto lending to Treasuries alone tells an incomplete story. A European Central Bank working paper published September 14 found that monetary-policy transmission into DeFi stablecoin deposit rates is weak and unstable in the short term. Rates can even move opposite to Fed policy before converging over a longer horizon.
Anthony DeMartino, co-founder and CEO of Sentora, argues that CDOR—which tracks overnight borrowing rates on USDC and USDT inside Aave V3—provides a better measure of on-chain credit conditions. The one-year Treasury measures what an investor gives up by choosing crypto lending over the safest available alternative, while CDOR measures what borrowing dollars inside Aave costs on any given day.
A useful assessment of crypto yields requires both figures. A return that clears CDOR but misses the Treasury rate has still failed the more basic opportunity-cost test.
The Risk Premium Question
DeMartino noted that the premium over CDOR compensates for smart contract, liquidity, and credit risk, but there is no standard rate applied across the market. The fair premium depends entirely on the specific protocols, curators, and assets an investor is exposed to.
As an analytical exercise, a plain stablecoin vault might reasonably need to clear the higher of the Treasury rate or CDOR plus another 100 to 300 basis points. Curated or leveraged strategies would need 300 to 600 basis points above that same floor. That range explains why a 4.1% yield appears inadequate against 4.45% Treasuries, while even a 5.1% crypto yield remains debatable once volatility and tail risk are considered.
Real-World Example: Tokenized Equities
Kraken's newly launched xStocks Vaults let investors keep exposure to tokenized equities like SPYx, QQQx, or NVDAx while the vault borrows stablecoins against that collateral and deploys proceeds into DeFi reward strategies. Kraken currently advertises a 2% net annualized yield for SPYx and QQQx and 1.8% for NVDAx, net of a 25% performance fee, with withdrawals taking three days and potentially longer under stress.
On a $10,000 SPYx position, that 2% yield works out to roughly $200 of additional annual reward, entirely separate from whatever the underlying stock itself does. However, a 2% loss specific to the crypto vault's strategy would erase that entire year's incremental return.
Multiple Scenarios Ahead
Under a bull case, organic borrowing demand stays strong enough that on-chain borrowing costs climb independent of Fed policy, allowing crypto lending yields to clear Treasuries through genuine demand. Under a bear case, higher-for-longer Fed policy eventually cools risk appetite broadly, weakening crypto activity and pushing borrowers to deleverage. In that scenario, stablecoin deposit rates would fall even as Treasuries stay elevated.
Crypto yield products are already easy to access, though the harder question is whether that yield compensates for the risk sitting underneath it.
