Funding rate arbitrage captures the difference between spot and futures prices through the periodic funding payments in perpetual swaps.
What Is Funding Rate Arbitrage
In perpetual futures, funding rates are periodic payments between long and short traders to keep the futures price close to spot. When funding is positive, longs pay shorts. Funding rate arbitrage captures these payments with a hedged position.
How It Works
| Step | Action |
|---|
| 1 | Identify a perpetually positive funding rate |
| 2 | Go long on spot (buy the asset) |
| 3 | Go short on perpetual futures (same size) |
| 4 | Collect funding payments from longs |
| 5 | Roll or close when funding turns negative |
The spot long hedges price risk while you collect the funding rate.
When Funding Rate Arbitrage Works
| Condition | Best For |
|---|
| Strong uptrend | Funding is positive as longs dominate |
| Low volatility | Less risk of liquidation on the short |
| High volume pairs | BTC, ETH perpetuals |
| Centralised exchanges | Binance, Bybit, OKX |
Risks
| Risk | How to Manage |
|---|
| Funding turns negative | Close and exit |
| Liquidation on short leg | Maintain sufficient margin |
| Spot-futures basis widens | Monitor basis carefully |
| Exchange risk | Use reputable exchanges |
| Slippage on entry/exit | Use limit orders |
Profit Calculation
| Input | Example |

| Position size | 10 BTC |

| Daily funding | 0.03% |
| Daily profit | 0.003 BTC |
| Annualised | ~10-15% (variable) |
Exchanges with Best Funding Opportunities

| Bybit | 0.01-0.03% per 8h | Very high |
| OKX | 0.01-0.04% per 8h | High |
| dYdX | Variable | Moderate |
Execution Tips
| Tip | Why |
|---|
| Enter spot first, then short | Avoids being net short |
| Use limit orders | Reduces slippage |
| Monitor funding every 8 hours | Funding payments occur at intervals |
| Close when funding turns negative | Otherwise you pay instead of receiving |
| Keep margin on the short | Prevent liquidation from price spikes |
Bottom Line
Funding rate arbitrage captures the spread between spot and futures by collecting funding payments. The strategy works best in strong trends with positive funding. Risks include liquidation, funding flipping negative, and exchange issues. Use careful position sizing, monitor funding schedules, and exit when the opportunity reverses. It’s a low-risk strategy when executed properly but requires active management.
