What is Funding Rate?
Funding rate is a periodic payment between long and short traders on perpetual futures. It keeps the futures price aligned with spot price. Typically settled every 8 hours (3x daily).
How It Works
Positive funding (most common): Longs pay shorts. This means more traders are long — the market is bullish. If funding is 0.01% per 8 hours, holding a $10,000 long position costs $1 every 8 hours ($3/day, $90/month).
Negative funding: Shorts pay longs. More traders are short — the market is bearish. Less common. If you are long during negative funding, you get PAID to hold your position.
Delta-Neutral Funding Strategy
Buy spot + short futures of same size. Your directional exposure is zero (delta-neutral). You collect funding payments from short position when funding is positive. At 0.03%/8h (during bullish periods), this generates ~0.09%/day = ~2.7%/month = ~32%/year risk-free (minus fees and slippage).
Best platforms for funding rate farming: PrimeXBT (0.01% maker, lowest cost to maintain position), MEXC (0% maker), Bybit. See PrimeXBT review and funding rate strategy guide.
What Is Funding Rate?
Funding rate is a periodic payment between long and short traders on perpetual futures contracts. It exists to keep the perpetual contract price close to the spot price. When the perp price is above spot (longs dominate), longs pay shorts. When the perp price is below spot (shorts dominate), shorts pay longs. Payments occur every 8 hours on most exchanges (00:00, 08:00, 16:00 UTC).
How Funding Rate Works (With Numbers)
Let us say BTC spot price is $65,000 and the perpetual price is $65,200 (trading at a premium). The exchange calculates a positive funding rate, for example 0.05% per 8-hour period:
| Position | Size | Funding Payment (0.05%) | Direction |
|---|---|---|---|
| Long $10,000 | $10,000 | -$5.00 | Pays |
| Short $10,000 | $10,000 | +$5.00 | Receives |
If funding stays at 0.05% per 8 hours for 24 hours, the long trader pays $15/day (0.15%). Over a month, that is $450 (4.5% of position). This is a significant hidden cost that many beginner traders ignore.
Reading Funding Rate Signals
| Funding Rate | Market Sentiment | Trading Implication |
|---|---|---|
| +0.01% (normal positive) | Slightly bullish | Neutral — this is the default state |
| +0.05 to +0.10% | Moderately bullish | Caution on new longs, consider collecting funding as shorts |
| +0.10 to +0.30% | Extremely bullish (euphoria) | High reversal risk, shorts collect significant funding |
| Above +0.30% | Mania / parabolic | Liquidation cascade imminent, avoid leverage entirely |
| -0.01% | Slightly bearish | Neutral to slightly bullish (contrarian) |
| -0.05 to -0.10% | Moderately bearish | Potential bottom, longs collect funding |
| Below -0.10% | Extreme fear | Strong contrarian buy signal, short squeeze likely |
Delta-Neutral Funding Rate Strategy
This is the most popular way to profit from funding rates without taking directional risk:
- Buy BTC spot (e.g., $10,000 worth on Bybit or OKX).
- Short BTC perpetual for the same amount ($10,000 short on futures).
- Net exposure: zero. If BTC goes up, your spot gains and futures loses equally. If BTC goes down, your spot loses and futures gains equally.
- Collect funding. When funding is positive (most of the time in bull markets), your short position receives funding payments every 8 hours.
At 0.05% funding per 8 hours, this strategy earns $15/day on a $10,000 position = $450/month = 54% annualized. In reality, funding fluctuates, so realistic returns are 15-40% APY depending on market conditions.

Common Mistakes with Funding Rates
- Ignoring funding cost when holding positions. A day trader who holds a long for 3 days at 0.1% funding pays 0.9% — more than many profit targets.
- Assuming positive funding means price will drop. In strong bull markets, funding stays positive for weeks while price keeps rising. Funding signals crowded positioning, not guaranteed reversal.
- Running delta-neutral without accounting for fees. Opening and closing the hedge costs trading fees. At 0.02% maker, a round trip costs 0.08% total. Subtract this from funding profits.
- Not monitoring funding rate changes. Funding can flip from positive to negative within hours during volatile events. Set alerts on Coinglass for extreme funding rate changes.
Frequently Asked Questions
Do I pay funding if I close before the funding time?
No. Funding is only charged/received at the exact funding timestamp (00:00, 08:00, 16:00 UTC on most exchanges). If you open and close a position between funding times, you pay zero funding. This is why many scalpers trade between funding windows.
Which exchange has the lowest funding rates?
Funding rates are similar across major exchanges because they are market-driven (based on the premium between spot and perp prices). The exchange does not set the rate. However, dYdX and Hyperliquid adjust funding hourly, which can lead to faster normalization and smaller extreme spikes.
Can funding rate make me lose money?
Yes. If you are long during sustained positive funding (bull market), you pay 0.3-1% daily. Over a week, this can erode 2-7% of your position regardless of price movement. Always factor funding into your trading plan.
