How Perpetual Futures Funding Works
Funding rates keep perpetual futures contracts anchored to the spot price. Every 8 hours, a funding payment is exchanged between long and short traders:
- Positive funding rate — The contract trades at a premium to spot. Longs pay shorts.
- Negative funding rate — The contract trades at a discount to spot. Shorts pay longs.
Why Funding Rates Matter
Funding rates are a market sentiment indicator:
- Persistently high positive rates signal an overleveraged long market, often preceding corrections
- Extreme negative rates indicate crowded short positions and potential for a short squeeze
- Near-zero rates suggest a balanced, healthier market
Annualized calculation: A 0.05% 8-hour rate equals approximately 54.75% annualized — a significant carrying cost.
Trading Strategies
- Funding arbitrage — Hold spot long + perpetual short to collect positive funding
- Contrarian signals — Extreme rates often signal crowded trades due for mean reversion
- Cost management — Factor funding into holding cost calculations
