Perpetual Futures Peg
The perpetual futures peg is the mechanism that ensures the price of a perpetual contract stays close to the price of the underlying spot asset. Unlike traditional futures, perpetual contracts do not have an expiration date, so they rely on the funding rate to prevent the contract price from drifting away from the spot market.
If the perpetual price is higher than the spot price, the funding rate becomes positive, forcing long position holders to pay short position holders. This payment creates an incentive to sell the contract, pushing the price back down.
Conversely, if the perpetual price is lower than the spot price, the funding rate becomes negative, incentivizing buyers. This dynamic keeps the derivative market aligned with the spot market.
Maintaining this peg is vital for the integrity of the derivatives ecosystem and for providing traders with a reliable instrument for hedging and speculation.
