Funding Rates in Crypto Perpetuals: How They Work and How to Trade Them
Perpetual futures use funding rates to stay anchored to spot prices. Understanding funding rates is essential for any derivatives trader.
Perpetual futures (perps) do not have an expiry date — unlike traditional futures that expire quarterly. To prevent them drifting away from spot price, a funding mechanism charges longs (if perps trade above spot) or shorts (if perps trade below spot) at regular intervals (every 8 hours on most exchanges, every second on Hyperliquid). Understanding funding rates turns a cost centre into a potential income source.
How Funding Rates Work
- Positive funding: perpetual trades above spot — longs pay shorts — signal of bullish sentiment
- Negative funding: perpetual trades below spot — shorts pay longs — signal of bearish sentiment
- Rate: typically 0.01-0.1% per 8-hour period — can spike to 0.3%+ during extreme sentiment
- Calculation: based on interest rate component + premium (difference between perp and spot price)
- Impact: if funding is 0.1%/8h and you are long $100,000 → you pay $100 per 8 hours = $300/day
Trading Funding Rate Signals
- Extreme positive funding + price at resistance → potential long liquidation incoming → consider short
- Extreme negative funding + price at support → potential short squeeze incoming → consider long
- Funding rate history: persistent positive funding during uptrend = genuine demand, not just speculation
- Cross-exchange comparison: if Binance funding is higher than Steyble Perps → potential arbitrage
- Mean reversion: extreme funding rates tend to normalise — trade the normalisation not the trend
Funding Rate Arbitrage
When BTC perpetuals have high positive funding: sell perps, buy spot (delta-neutral) → earn funding rate with no directional risk. At 0.1%/8h = 109% annualised gross yield. Practical net yield after borrow costs: 30-80% APY depending on conditions. Execute via Steyble Perps (short side) + Steyble spot (long side) — both managed in one portfolio view for the position.
