The funding rate is a periodic payment between long and short traders in a perpetual futures contract. It keeps the perpetual contract’s price anchored to spot. When longs outnumber shorts, longs pay shorts. When shorts dominate, shorts pay longs. The rate adjusts automatically based on the gap between the perpetual price and the spot price.
How funding rates work
Perpetual futures have no expiry date, so there is no natural mechanism to converge the contract price toward spot. Funding rates fill this role. If the perpetual trades above spot, longs pay shorts every 8 hours (the standard interval on most exchanges). This cost discourages excessive long positioning and nudges the perpetual price back toward spot. If the perpetual trades below spot, shorts pay longs.
Rates are expressed as a percentage per 8-hour period. A rate of 0.01% per 8 hours equals roughly 10.95% annualized. During bull market extremes, rates can reach 0.1–0.3% per 8 hours, or 36–109% annualized. Holding a leveraged long during these periods is genuinely expensive, even before price moves against you.
What this means for traders
Funding rates are both a cost and a sentiment signal. Consistently high positive rates (0.05% or above per 8 hours) indicate over-leveraged longs and can precede sharp corrections when positions get liquidated in a cascade. Consistently negative rates signal excessive short positioning, which can set up a short squeeze. Neither condition guarantees a move, but both warrant adjusting your position size.
Checking the funding rate before entering a leveraged position is as routine as checking the bid-ask spread on a spot trade. Coinglass aggregates funding rates across exchanges in real time.

A concrete example
You hold 5 BTC long in a perpetual contract at $90,000. The funding rate is 0.05% every 8 hours. That is $225 per 8-hour period, or $675 per day, just to maintain the position. Over a week with no price movement, you pay $4,725 in funding. If BTC rises 5% during that week, the funding cost is absorbed. If BTC is flat or falls, you lose both on the position and on the funding. The break-even price change for the week is roughly 5.25%, just to cover funding at that rate.
Frequently asked questions
Do funding rates apply to quarterly futures?
No. Quarterly futures converge to spot at expiry, so they do not need a funding mechanism. The premium or discount on a quarterly contract (the basis) is priced in at entry and converges to zero at settlement.
Can you profit from funding rates?
Yes, through basis trading. Buy the asset spot, short the perpetual, and collect the positive funding payments from longs while hedging your directional exposure. This is a common institutional strategy during bull markets when rates are elevated. Returns of 10–30% annualized are achievable in high-funding environments, with exchange counterparty risk as the main downside.
What was the highest funding rate recorded?
During peak bull market periods in 2021, ETH and BTC perpetuals on some exchanges hit 0.3% per 8 hours (roughly 109% annualized) for several days. More speculative tokens like DOGE hit even higher rates briefly. These extremes are reliably associated with short-term market tops, not bottoms.
