Frequently Asked Questions

What is the funding rate in crypto futures?

The funding rate is a periodic payment exchanged between long and short position holders on perpetual futures contracts. It keeps the perpetual contract price anchored to the spot price. Positive rates mean longs pay shorts; negative means shorts pay longs.

How often is funding paid?

On most exchanges, funding is paid every 8 hours (at 00:00, 08:00, and 16:00 UTC). Some exchanges like Bybit also offer 4-hour and 1-hour funding intervals on select pairs.

Can I profit from funding rates?

Yes. A common strategy is funding rate arbitrage: hold a spot position and short the perpetual when funding is highly positive. You collect funding payments while being market-neutral. This works best during bullish periods when funding rates stay consistently positive.

Does funding rate affect my liquidation price?

Yes. Accumulated negative funding payments reduce your margin balance over time, which can gradually move your liquidation price closer. This is especially impactful for high-leverage positions held over several funding periods.
