Funding Rate Explained: Who Pays and Why
The funding rate is a periodic payment between traders who are long and traders who are short a perpetual futures contract. When funding is positive, longs pay shorts; when it is negative, shorts pay longs. It exists to keep the price of a perpetual contract close to the real price of the coin, and it is one of the best public gauges of whether traders are crowded on one side.
Why perpetual futures need funding
A traditional futures contract has an expiry date. On that date it settles at the spot price, so its price naturally converges to spot. A perpetual future never expires, so there is no settlement to pull it back.
Funding solves this. If the perpetual trades above spot because more traders want to be long, longs pay shorts. That makes holding a long more expensive and holding a short more attractive, which pushes the contract price back toward spot. The reverse happens when the perp trades below spot.
The exchange does not keep funding payments. They move directly from one side of the market to the other.
Who pays whom
| Funding | Who pays | What it usually means |
|---|---|---|
| Positive | Longs pay shorts | More demand for longs; the perp trades above spot |
| Around zero | Little or nothing | Balanced positioning |
| Negative | Shorts pay longs | More demand for shorts; the perp trades below spot |
How often funding is paid
- Hyperliquid: every hour. That is why Whale Radar shows funding as a percentage per hour.
- Binance, Bybit, OKX and most centralized exchanges: usually every 8 hours, with some pairs on 4-hour or 1-hour intervals.
Always compare funding over the same period. A rate of 0.01% per hour equals 0.08% per 8 hours, 0.24% per day, and roughly 88% per year if it stayed there (it rarely does).
How the funding rate is calculated
Exchanges use slightly different formulas, but most combine two parts:
- A premium component: how far the perpetual price is above or below the spot index. A larger premium means larger funding.
- An interest component: a small fixed rate that reflects the cost of borrowing the quote currency versus the base currency.
The rate is usually averaged over the funding period and capped to prevent extreme payments. You do not need to compute it yourself: the current rate is shown on every coin page, for example BTC funding.
Worked examples
A long paying funding
You are long $10,000 of BTC on Hyperliquid and funding is +0.01% per hour.
- Each hour you pay: 10,000 × 0.01% = $1.
- Each day: about $24.
- Over a week: about $168, before trading fees.
If you used 10x leverage, your margin is $1,000, so a week of funding costs almost 17% of your margin. This is why funding matters most for leveraged positions held for days.
A short receiving funding
You are short $10,000 of a coin with funding at +0.05% per hour. You receive $5 per hour, about $120 a day. That can look attractive, but high positive funding often appears during strong rallies, and the price move against your short can be far larger than the funding you collect.
Negative funding
Funding at −0.03% per hour means shorts pay longs. Traders who are long receive payments. Deeply negative funding often appears after sharp drops, when many traders pile into shorts.
What funding tells you about the market
Very high positive funding
Many traders are long and willing to pay to stay long. The trade is crowded. If price stalls or drops, those longs may close or get liquidated, which can turn into a fast move down known as a long squeeze.
Very negative funding
Shorts are crowded. A move up can force them to buy back, producing a short squeeze. Some of the sharpest rallies in crypto start from deeply negative funding.
Funding near zero
Positioning is balanced, or there is little leverage in the market. It says less on its own.
Combine funding with open interest
Funding shows which side pays. Open interest, the total value of open contracts, shows how much leverage is in the market.
- Rising open interest with rising positive funding: new leveraged longs are entering.
- Rising open interest with negative funding: new shorts are entering.
- Falling open interest: positions are closing, voluntarily or through liquidations.
Whale Radar shows funding and open interest side by side on each coin page and in the market table on the live dashboard, with filters for coins with the highest and most negative funding.
Common mistakes
- Treating funding as a trade signal. High funding can stay high for days in a strong trend. It describes positioning; it does not time reversals.
- Comparing 1-hour and 8-hour rates directly. Convert to the same period first.
- Ignoring funding on long holds. For leveraged positions held for weeks, funding can cost more than trading fees.
- Farming funding without a hedge. Collecting funding with an unhedged position exposes you to the full price move.
FAQ
Is a positive funding rate bullish?
It means more traders are positioned long, which reflects bullish sentiment. Extremely high funding is often a sign of a crowded trade rather than a reason to buy.
Do I pay funding if I close before the funding time?
On exchanges that pay every 8 hours, you only pay or receive funding if you hold the position at the funding timestamp. On Hyperliquid, funding is settled every hour.
Does spot trading have funding?
No. Funding only applies to perpetual futures.
Where can I see funding for every coin?
The coin prices page lists funding, open interest and volume for every market on Hyperliquid.
