GHO Price Stability Mechanism Explained: Aave’s New Approach to Decentralized Stablecoins

The issuance logic and collateral mechanism of GHO

In the Aave protocol, users can collateralize crypto assets to mint GHO. Each minting is executed by a Facilitator, who has a set capacity limit to ensure the system is not unbalanced due to over-minting.

The value of the collateralized assets is always higher than the issuance of GHO, thereby ensuring its over-collateralization safety. When the value of the collateralized assets drops, the system will automatically trigger liquidation or destruction mechanisms to prevent depegging risks.

Why can GHO maintain a $1 peg?

The price anchoring of GHO relies on a two-tier mechanism:

• Market Arbitrage: GHO allows users to repay or redeem at any time for 1 dollar. When the price is below the peg, arbitrageurs buy to repay; when it’s above the peg, they mint and sell.
• Governance intervention: Aave DAO can indirectly control market supply by adjusting lending rates, discount ratios, and Facilitator capacity, similar to the interest rate policies of central banks.

This allows the price fluctuations of GHO to be automatically absorbed, forming a robust dynamic balance.

The economic principles of interest rate adjustment and discount mechanisms

Unlike traditional stablecoins, the borrowing rate of GHO is not entirely determined by the market, but is set by Aave Governance through smart contracts.

At the same time, Aave introduced a “discount model,” where users holding stkAAVE can enjoy lower borrowing rates. This mechanism creates dual incentives:

• Encourage users to hold and stake AAVE;
• Reduce the financing costs of the core community and enhance system stability.

This “decentralized interest rate policy” is the innovation of GHO, which also gives it greater macro-control capabilities.

Market Arbitrage and Supply-Demand Dynamics

The price fluctuations of GHO will trigger market self-correction:

• When the market price is
• When the price > 1 dollar, users will mint GHO and sell it, increasing the supply.

At the same time, Aave DAO can adjust parameters based on market conditions, allowing the system to return to its peg more quickly. This combination of automated arbitrage + governance adjustments makes GHO a “self-balancing” stable system.

The market potential and challenges of GHO

In the current stablecoin market, USDT and USDC dominate, but both are regulated by centralized institutions. In contrast, GHO is managed by smart contracts and a DAO, aligning more with the spirit of Decentralization Finance (DeFi).

In the future, with the addition of more Facilitators and multi-chain expansion, GHO may become an important base currency for cross-chain payments, lending, and liquidity markets.

However, GHO still faces competition from algorithmic stablecoins like DAI and FRAX, and its governance efficiency and liquidity depth will determine its long-term value.
