PayPal’s PYUSD is offering one of the highest stablecoin lending yields on Aave V3 Ethereum, standing well above rates available on much larger USDC and USDT markets. According to the Aave V3 Ethereum market dashboard, rates remain variable and respond dynamically to borrowing demand and available liquidity. PYUSD’s higher return currently reflects a much tighter lending market rather than simply a larger pool of capital.
A DeFiStar snapshot on October 14 placed PYUSD’s supply APY at approximately 6.91%, compared with 3.74% for USDC, 3.28% for USDT and 3.36% for DAI. USDT held roughly $2.78 billion in supplied liquidity and USDC about $2.39 billion, while PYUSD had only $7.92 million supplied. The yield premium therefore sits alongside dramatically lower liquidity and higher utilization, with about $7.18 million of PYUSD already borrowed.
High Utilization Pushes PYUSD Rates Higher
Aave’s interest-rate model adjusts borrowing and supply rates as utilization changes. When a larger share of deposited assets is borrowed, rates rise to attract new suppliers and encourage borrowers to repay. PYUSD’s roughly 91% utilization leaves considerably less idle liquidity than its headline APY alone suggests, making the higher rate a reflection of tighter market conditions rather than a guaranteed return advantage.
That contrasts with the scale of the major dollar stablecoins. USDC and USDT account for billions of dollars of supplied assets on Aave V3 Ethereum, giving those markets substantially deeper liquidity even when their quoted supply yields are lower. DeFiStar currently estimates that Aave V3 holds about 67.6% of the Ethereum lending TVL covered by its dataset. Protocol scale and individual pool yield are separate metrics: the deepest market does not necessarily pay the highest rate at a particular moment.
Rate management is also visible in Aave’s own GHO ecosystem. Governance recently raised the GHO borrowing rate to 4.5% as Stability Module liquidity tightened, aligning Core borrowing costs with the Aave Savings Rate. Changing a borrow rate can alter incentives for borrowers and suppliers, but it does not mechanically restore USDC or USDT liquidity to a depleted conversion module.
Stablecoin Yield Becomes Increasingly Automated
The differences between lending markets are also creating opportunities for automated allocation strategies. Ditto Network’s live Yield Split Vault accepts USDC on Ethereum and reallocates capital across Aave V3, Spark, Fluid and Morpho according to realized on-chain lending rates. The ERC-4626 structure turns rate dispersion between protocols into an automated allocation problem rather than requiring depositors to move capital manually whenever yields change.
More complex strategies can produce even larger headline returns, but those rates often depend on leverage, collateral parameters and maturity structures. A previous Aave supply-cap expansion for Pendle PT-USDG increased capacity for leveraged fixed-yield strategies, although that specific May 2026 principal token has since matured. Looping yields should therefore be separated from basic stablecoin supply APYs because leverage can amplify liquidation, funding and oracle risks alongside returns.
At the broader Ethereum level, lending rates have recently been relatively stable despite individual outliers. DeFiStar’s 30-day data show average stablecoin APYs declining only 0.07 percentage points, from 3.31% to 3.24%. PYUSD’s roughly 6.9% yield is therefore better understood as a localized utilization premium inside a small Aave market than evidence that Ethereum stablecoin yields are rising generally. Its persistence will depend on whether additional supply enters the pool, borrowing demand remains elevated or utilization falls enough to compress the rate again.
