Futures Funding Rates

Mechanism

Futures funding rates are periodic payments exchanged between traders holding long and short positions in perpetual futures contracts. This mechanism ensures that the perpetual future price remains closely anchored to the underlying spot asset price. When the funding rate is positive, long position holders pay short position holders; a negative rate means shorts pay longs. These payments prevent significant and sustained divergences between the perpetual future and its spot counterpart. It is a critical component of perpetual swap market microstructure.
