Cryptocurrency trading, especially in volatile markets, can be a rollercoaster ride. One moment you're riding high, and the next, you're facing liquidation. While many traders focus on market direction and leverage, few pay attention to a critical yet often overlooked factor: funding rates.
In this comprehensive guide, we'll dive deep into funding rates—what they are, how they work, and why they matter for your trading strategy. We'll also compare funding rates across major exchanges like OKEx, Huobi, BitMEX, and Binance to help you make informed decisions.
What Are Funding Rates?
Funding rates are periodic payments exchanged between long and short traders in perpetual swap contracts. Unlike fees charged by exchanges, these payments are trader-to-trader mechanisms designed to tether perpetual contract prices to their underlying spot prices.
Key Characteristics of Funding Rates:
- Not a Fee: Funding rates are payments between traders, not fees collected by the exchange.
- Time-Bound: Typically settled three times daily (e.g., at 08:00, 16:00, and 24:00 UTC). No持仓? No payment.
- Purpose: To narrow the gap (basis) between perpetual contract prices and spot prices.
How Funding Rates Are Calculated
The exact formula varies by exchange but generally follows this structure:
Funding Rate = Clamp(MA((Mid Contract Price - Spot Index Price) / Spot Index Price - Interest), a, b)Where:
- Clamp: Caps the rate between bounds
aandb. - MA: Moving average over a specified period (e.g., 1 minute).
- Interest: Often zero in crypto perpetuals.
Determining Payment Direction:
- Positive Rate: Longs pay shorts.
- Negative Rate: Shorts pay longs.
Funding Fees: The Hidden Cost of Trading
To calculate your funding fee:
Funding Fee = Position Value × Funding RatePosition Value Formulas:
- Coin-Margined:
(Face Value × Contracts) / Mark Price - USDT-Margined:
Face Value × Contracts × Mark Price
Why Do Funding Rates Exist?
Perpetual contracts lack expiry dates. Without a mechanism like funding rates, the gap between contract and spot prices could widen indefinitely. Funding rates act as a corrective measure, ensuring price convergence.
Note: Traditional futures (with expiry dates) don’t need funding rates—their交割 process naturally aligns prices.
Exchange Showdown: Who Offers the Lowest Funding Rates?
Let’s compare OKEx, Huobi, BitMEX, and Binance using real-world data from Skew:
| Exchange | Avg. Funding Rate | Cost for $100K Position (30 Days) |
|---|---|---|
| OKEx | 0.002% | $603 |
| Huobi | 0.0044% | $1,323 (2.2× OKEx) |
| BitMEX | 0.0051% | $1,539 (2.6× OKEx) |
| Binance | 0.0071% | $2,142 (3.6× OKEx) |
Key Takeaway: OKEx’s funding rates are 50% lower than Huobi/BitMEX and 65% lower than Binance, saving traders hundreds—or even thousands—over time.
