What is Perpetual Futures Funding?

Traditional futures contracts have an expiration date. When that date arrives, the contract settles and traders must roll to a new contract if they want to maintain exposure.

Perpetual futures have no expiration. They can be held indefinitely. This makes them popular with crypto traders who want continuous exposure without the hassle of rolling contracts.

But without expiration, how do perpetual futures stay aligned with the spot price? This is where funding comes in.

Funding is a periodic payment between traders holding long and short positions. It occurs at regular intervals, typically every 8 hours (though some exchanges use 4-hour or 1-hour intervals).

When the perpetual price trades above the spot price, funding is positive. Longs pay shorts. This incentivizes selling (or shorting) the perpetual, pushing its price back toward spot.

When the perpetual trades below spot, funding is negative. Shorts pay longs. This incentivizes buying the perpetual, pushing its price up toward spot.

The payment is proportional to position size. If funding is 0.01% and you hold $10,000 worth of position, you pay or receive $1 that interval.

Funding rates reflect market sentiment and positioning. During bullish periods when many traders are long, funding tends to be positive and sometimes very high.

During bearish periods or market crashes, funding often flips negative as short interest increases.

Rates can change dramatically over hours or days. A pair showing 0.1% funding might be at 0.01% or even negative within 24 hours.

External factors also matter: news events, liquidation cascades, and capital flowing in or out of the crypto market all affect funding.

Positive funding means longs pay shorts. This is common during bull markets and indicates traders are willing to pay a premium to hold long positions.

Negative funding means shorts pay longs. This typically occurs during bearish sentiment when traders are paying to stay short.

Extremely high positive or negative funding often precedes a reversal, as the imbalance becomes expensive enough to force position changes.

Neutral funding (close to zero) suggests balanced positioning with no strong directional pressure.

Raw funding rate: the percentage paid per interval. Common range is -0.1% to +0.1% per 8 hours, but can spike much higher during volatile periods.

Annualized APR: raw rate extrapolated to a yearly figure. A 0.01% per 8-hour rate equals roughly 10.95% APR (0.01% × 3 × 365).

Historical funding: look at how funding has behaved over days or weeks, not just the current snapshot. Persistent positive funding is more meaningful than a single high reading.

Funding across exchanges: rates differ between Binance, Bybit, OKX, etc. These differences can create opportunities but also add complexity.

If you hold leveraged positions, funding directly impacts your PnL. High positive funding costs you money if you are long.

Funding arbitrage strategies attempt to capture these payments by holding offsetting positions.

Understanding funding helps you time entries. Entering a long when funding is extremely positive means you are paying a premium that may not last.

Funding is not a perfect predictor of price direction, but extreme readings often signal crowded trades that may unwind.
