The Stability Fee is an annual percentage yield applied to the PHT generated from a vault, similar to the interest paid for collateralizing digital assets and borrowing PHT.
Paid in PHT, the Stability Fee contributes to the APACX Protocol's reserves, ensuring that the protocol has sufficient resources to maintain the peg.
To maintain the peg of PHT to PHP, the APACX Protocol employs dynamic stability fee adjustments based on market conditions. The protocol uses a Proportional-Integral-Derivative (PID) controller model, which fine-tunes the stability fees during various market cycles.
Key Stability Adjustments:
Market Demand for PHT: Stability fees are adjusted based on changes in demand for PHT.
PHP-USD Exchange Rate Volatility: Fluctuations in the exchange rate between PHP and USD prompt adjustments in the stability fee.
Collateral Risk: Risk factors associated with the asset type of collaterals backing PHT are also considered.
Stability fees collected over time are stored in a risk reserve or surplus buffer.
This reserve ensures system stability by providing a cushion in case of market stress or volatility.
Surplus funds are gradually distributed to maintain the protocol's balance.
The PHT Yield Rate (PYR) allows PHT holders to earn yield by locking their PHT in a designated contract. This mechanism serves two purposes: providing an incentive for holding PHT long-term and helping maintain the peg to PHP.
PYR and Stability Mechanisms:
Above Peg: If PHT trades above the 1:1 peg (greater than 1 PHP), the protocol may lower the PYR or increase stability fees to reduce demand and bring the price back to the peg.
Below Peg: If PHT trades below the peg (less than 1 PHP), the protocol may increase the PYR or decrease stability fees to encourage demand and restore the peg.
