Funding Rate Explained

Calculation

Funding rate represents periodic payments exchanged between traders holding opposing positions in perpetual futures contracts, ensuring the contract price closely mirrors the underlying spot market price. This mechanism prevents perpetual contracts from diverging indefinitely from the spot market, maintaining alignment through incentivized arbitrage. The rate is determined algorithmically, based on the premium or discount between the perpetual contract and the spot index, adjusted for time; a positive funding rate indicates long positions pay shorts, while a negative rate signifies the opposite. Consequently, funding rates influence trading strategies, particularly for those aiming to capitalize on rate differentials or manage carry costs.
