These are the algorithmic rules embedded in perpetual swap contracts designed to anchor the contract price to the underlying spot asset’s reference price. The core function involves periodic payments exchanged between long and short positions based on the deviation from parity. Understanding the calculation frequency and rate determination is essential for managing basis risk.
Incentive
When the perpetual contract trades at a premium to the spot index, longs pay shorts, creating a negative incentive to hold long positions and a positive incentive to hold short positions. This mechanism is designed to align the derivative’s price with the cash market through continuous, small cash flows. Traders must factor these expected payments into their total cost of carry analysis.
Adjustment
The periodic calculation and settlement of the rate serve as the primary tool for maintaining convergence between the perpetual futures price and the spot index. Significant positive or negative rates indicate persistent directional imbalance in the market. Strategic traders use the magnitude and sign of this adjustment as a direct signal of market positioning stress.
