Crypto funding rates: what they are and how they work
A crypto funding rate is a periodic payment between traders holding perpetual futures. It often keeps the contract near spot and can flip sign.

- Positive funding means longs pay shorts; negative funding reverses that.
- The rate blends a premium to spot with an interest component.
- Funding can flip sign, making holding costs unpredictable.
- Leverage can lead to liquidation if margin falls too low.
- Perpetual futures have no expiry; US retail access is limited.
A perpetual future is a crypto contract with no settlement date. Without an expiry to pull its price toward spot, exchanges use funding to tie the two prices together. The exchange publishes a rate, and the two sides pay each other at set intervals.
How does the funding rate work?
The payment moves directly between traders, not to the exchange. The sign of the rate decides which side pays. When the perpetual trades above spot, funding is usually positive, and longs pay shorts; when it trades below spot, funding is usually negative, and shorts pay longs. The rate has two parts: a premium to spot and an interest component, and exchanges often cap the total.
Why do traders watch funding?
Traders watch the rate as a sentiment gauge. A strongly positive rate usually means many traders are long. A strongly negative rate points to the other side.
- How crowded the long or short side looks
- What it costs to keep a leveraged position open
- Whether the rate is high or low compared with its recent past
- How quickly the rate has changed
What risks and limits matter?
Funding can flip sign, so a payment you receive in one interval can become a cost in the next. That makes the total cost of holding a leveraged position hard to predict.
How is it different from futures?
Traditional futures expire on a set date and converge toward spot. A perpetual future has no expiry, and funding takes the place of that convergence. In the United States, retail access to perpetual futures has been limited, and these contracts trade mostly offshore.
Frequently asked questions
No. Funding applies to perpetual futures positions, not to coins you hold in a spot wallet.
The exchange sets the schedule, usually at fixed intervals. The rate can change or flip sign each time.
No. Each exchange sets its own rate and schedule, so the same asset can carry different rates.
You do not get a separate bill. The exchange takes the payment from your margin balance. If the balance cannot cover it, the position may be closed.
