Funding Rates Explained
A funding rate is a periodic payment between long and short traders that keeps perpetual futures near spot price. Learn how it works and what it signals.
A funding rate is a periodic payment exchanged between traders holding long and short positions in a perpetual futures contract, designed to keep the contract's price close to the underlying spot price. When the funding rate is positive, longs pay shorts; when it is negative, shorts pay longs.
Funding rates exist because perpetual futures never expire. Without a settlement date to pull the contract back to the spot price, exchanges need another mechanism — and funding is it. For traders, funding is both a cost to manage and a widely watched indicator of market positioning.
Why Perpetual Futures Need Funding
A traditional futures contract has an expiry date. At expiry, it settles at the spot price, so its price naturally converges with spot over time. A perpetual future has no expiry, so its price could drift away from spot indefinitely if many traders want to be long (or short) at once.
Funding solves this. If the perpetual trades above spot, longs pay shorts. That makes holding a long more expensive and holding a short more attractive, which pushes the perpetual price back toward spot. The opposite happens when the perpetual trades below spot.
How the Funding Rate Is Calculated
Exact formulas vary by exchange, but most combine two parts:
- 1Premium component: how far the perpetual's price is from a spot price index over the interval.
- 2Interest component: a small baseline rate reflecting the difference in borrowing costs between the two assets in the pair, often set to a fixed small value.
The result is a percentage applied to each position's notional value at every funding interval. Many exchanges also cap how high or low the rate can go.
How Much Funding Costs: An Example
Funding is charged on your position's full size, not your margin.
| Item | Value |
|---|---|
| Your margin | $1,000 |
| Leverage | 10x |
| Position size (notional) | $10,000 long |
| Funding rate per 8-hour interval | +0.01% |
| Funding paid per interval | $1 |
| Intervals per day | 3 |
| Funding paid per day | $3 |
The figures are illustrative. At 0.01% per eight hours, that is roughly 11% per year on the notional value — or about 110% of your margin at 10x leverage. In heated markets funding can be many times higher. That is why holding leveraged positions for long periods can be expensive even if the price barely moves. Read leverage in crypto trading before using it.
What Funding Rates Tell You About the Market
Traders watch funding across major exchanges because it reveals how leveraged traders are positioned:
| Funding pattern | What it may suggest |
|---|---|
| Near zero or slightly positive | Balanced positioning, typical in calm markets |
| Strongly positive for a long period | Crowded longs; vulnerable to a long squeeze if price drops |
| Negative | More demand for shorts; possible short squeeze if price rises |
| Sudden spike | Rapid build-up of leverage, often around news |
Crowded positioning can contribute to liquidation cascades, where forced selling or buying accelerates a move. However, funding can stay extreme for a long time, and it says nothing certain about direction. Use it together with open interest and other indicators, not on its own.
Funding on Centralized vs Decentralized Exchanges
Funding exists on both centralized exchanges and decentralized perpetual exchanges such as Hyperliquid and dYdX. Differences to note:
- Interval: many centralized exchanges settle every eight hours; several decentralized platforms settle hourly.
- Price sources: decentralized platforms rely on oracles for index prices.
- Transparency: on-chain platforms let anyone verify positions and payments.
- Platform risk: both carry risk — exchange failure on one side, smart-contract and oracle risk on the other.

How to Check Funding Before You Trade
Most exchanges display funding information on the trading screen for each perpetual contract. Before opening or holding a position, look for:
- 1The current or predicted funding rate for the next interval, and whether it is positive or negative.
- 2The time until the next funding settlement. You pay or receive funding only if you hold the position at that moment.
- 3The funding interval — every eight hours, every hour or continuous — so you can estimate the daily cost.
- 4Historical funding for the contract, which shows whether current levels are unusual.
- 5Any caps on the rate, listed in the contract specifications.
Then multiply the rate by your position's notional value and by the number of intervals you expect to hold. If that cost would wipe out a meaningful part of your expected gain, reconsider the trade or its size.
Funding and the spot-perp basis
Funding is closely linked to the "basis," the gap between the perpetual price and the spot price. When the perpetual trades at a premium, funding tends to be positive; when it trades at a discount, funding tends to be negative. Watching both together gives a clearer picture of how much traders are willing to pay for leveraged exposure in one direction.
Common Mistakes With Funding Rates
- 1Ignoring funding when holding positions for days or weeks. Small rates compound into large costs.
- 2Forgetting leverage multiplies funding relative to margin.
- 3Opening a position just before a funding settlement without checking the rate.
- 4Treating extreme funding as a guaranteed reversal signal.
- 5Assuming funding-capture strategies are risk-free. Funding can flip, and the derivative leg can still be liquidated.
Bottom line
Funding rates are payments between long and short traders that anchor perpetual futures to spot prices. They are a real cost for leveraged traders and a useful window into market positioning, but not a crystal ball. Check the rate and interval before opening a position, remember that funding scales with your full position size, and keep leverage modest.
Частые вопросы
What does a positive funding rate mean?
A positive funding rate means traders holding long positions pay those holding short positions. It usually happens when the perpetual contract trades above the spot price because demand for leveraged longs is strong. Persistently high positive funding can signal crowded bullish positioning, which some traders treat as a warning sign.
How often is the funding rate paid?
It depends on the exchange. Many centralized exchanges settle funding every eight hours, while some platforms, including several decentralized perpetual exchanges, settle hourly or continuously. Check the contract specifications on the platform you use, because the interval affects how quickly funding costs add up.
Do I pay funding if I trade spot crypto?
No. Funding applies only to perpetual futures positions. If you buy and hold coins on a spot market, there is no funding rate. If you hold a perpetual position at the moment funding is settled, you will either pay or receive funding depending on its sign and your direction.
Can funding rates be used to earn yield?
Some strategies try to capture funding by holding spot and taking an opposite perpetual position, a delta-neutral approach. Funding can turn negative, exchanges can fail, and liquidations can still happen on the perpetual side, so these strategies carry real risks despite sounding market-neutral.
