The funding rate is a payment mechanism unique to cryptocurrency perpetual futures contracts. Unlike traditional futures that settle on a fixed date, perpetuals have no expiry. The funding rate is a periodic payment (typically every 8 hours) between long and short traders that keeps the perpetual contract price tethered to the underlying spot price.
Positive vs Negative Funding Rate
Positive funding rate: The perpetual price is above spot. Longs pay shorts. This incentivizes arbitrageurs to short the perpetual (and buy spot), pushing the perpetual price down toward spot.
Negative funding rate: The perpetual price is below spot. Shorts pay longs. This incentivizes arbitrageurs to buy the perpetual (and short spot), pushing the perpetual price up toward spot.
On most exchanges (Binance, OKX, Bybit), funding payments occur every 8 hours: 00:00, 08:00, and 16:00 UTC. You must hold a position at those exact times to pay or receive funding.
Funding Rate as a Sentiment Signal
Persistently elevated positive funding signals that retail traders are heavily long and paying to hold those positions. Historically, funding rates above 0.1% per 8-hour period sustained for multiple days have preceded short-term corrections, as the cost of holding longs increases and eventually forces liquidations.
Negative funding can signal capitulation — shorts are paying to hold, suggesting extreme bearishness that sometimes coincides with local price bottoms.
Calculating Funding Costs
Funding payment = Position notional value × Funding rate. At $50,000 notional and 0.03% per 8 hours: $50,000 × 0.0003 = $15 per funding period = $45 per day. Use the Funding Rate Calculator to calculate the annualized cost for any position and funding rate.
