The Aave community is moving to recalibrate GHO's dual-rate structure, proposing a 25 basis point increase on its Ethereum Core market while maintaining the established spread across Prime. Under the GHO Stewards framework, the Risk Council would raise the Core borrow rate from 4.25% to 4.50% APR, bringing it into alignment with the Aave Savings Rate. Simultaneously, the Prime base rate would shift from 2.75% to 3.00%, preserving the 25 bps discount relative to Core that was introduced in August. This coordination addresses a widening arbitrage gap that has become costly for the protocol to sustain.
The motivation for these adjustments stems from competitive pressure in broader lending markets. When the Core rate last increased in August, policymakers intended a follow-up adjustment once competing stablecoins—USDC and USDT—reached 4.50% borrowing costs. Those assets have now arrived at 4.39%, narrowing the gap considerably. More pressingly, GHO currently trades cheaper to borrow than deposit: borrowers pay 4.25% to mint while depositors earn 4.50% through sGHO, a 25 bps spread funded entirely by the protocol. At 4.50%, GHO's borrow rate would exceed USDC and USDT rates by a modest margin, compensating the protocol for its stable asset status while remaining competitive. This alignment is essential for sustainable economics, as perpetual negative carry undermines GHO's long-term viability as a system.
The Prime adjustment follows methodical precedent. By raising the base rate to 3.00%, Prime's rate at the kink point rises to 4.25%, with borrowers at the current 86% utilization paying approximately 4.17%—up from 3.92%. This preserves the intended Prime discount while proportionally increasing borrowing costs across that market. The strategy reflects Aave's calibrated approach to maintaining separate rate curves suited to institutional and retail liquidity profiles.
GHO's peg stability adds urgency to these moves. The token traded below $0.999 for most of September and closed October near $0.9993, while Stability Module reserves have contracted sharply—the USDC GSM is now depleted and the USDT reserve holds only 22.5M. Higher borrowing rates may discourage new minting and encourage repayment, potentially tightening supply and supporting the peg. Borrowers seeking to acquire GHO can still mint through remaining Stability Modules fee-free or purchase on secondary markets, preserving optionality while price pressure exists. As GHO matures beyond its launch phase, aligning its cost of capital with market rates and savings incentives will prove critical to establishing it as a reliable collateral asset across DeFi.
