Funding Rate in Crypto: What It Is and Who Pays

The funding rate is a periodic payment exchanged between traders holding long and short positions in a crypto perpetual futures contract. When the rate is positive, longs pay shorts. When it is negative, shorts pay longs. The exchange does not keep the payment: it simply moves money between the two sides to keep the perpetual price close to the spot price.

Funding is one of the core mechanics of crypto derivatives, and it is easy to ignore until it quietly eats a large part of a trade's profit. This guide covers who pays whom, how funding is calculated, what it costs in money, how to read it as a sentiment signal, and how to factor it into a trade.

Quick answer: The crypto funding rate is a recurring payment between long and short holders of a perpetual futures contract, commonly settled every 8 hours. A positive rate means longs pay shorts; a negative rate means shorts pay longs. The payment equals position notional multiplied by the funding rate, and it keeps the perpetual price anchored to spot.

Funding rate: key facts

What is the funding rate in crypto?

The funding rate is the mechanism that keeps a perpetual futures contract trading close to the underlying spot price. A traditional futures contract has an expiry date, and on that date it settles against spot, so the two prices must converge. A perpetual future never expires, so it needs a different anchor. The funding payment is that anchor.

The perpetual swap was introduced by BitMEX in 2016, with funding built into its design. Today most crypto derivatives exchanges list perpetuals, and funding is the defining cost of holding them.

Funding is a transfer between traders. You only pay or receive funding if you hold a position at the moment funding settles; a trade opened and closed between two settlement times pays no funding.

Who pays the funding rate?

The side that is pushing the perpetual price away from spot pays the funding rate. When the perpetual trades above the spot index, funding is usually positive and longs pay shorts. When the perpetual trades below the spot index, funding is usually negative and shorts pay longs.

The chart below shows that process. While longs dominate, the perpetual trades above the spot index. Funding payments, not a settlement date, pull the contract back toward spot over time.

How is the funding rate calculated?

The funding rate is usually built from two parts: a premium component and an interest component. The exact formula, caps and intervals vary by exchange, so always read the contract specification of the venue you use.

1. Premium component. This measures how far the perpetual price sits above or below the spot index (an average of prices from several spot exchanges). A large premium pushes funding positive; a discount pushes it negative.
2. Interest component. This reflects the difference in borrowing rates between the two assets in the pair (for example, a stablecoin and the base coin). On many venues it is a small fixed value per interval.
3. Combination and caps. The exchange combines the two parts, often smooths the premium over the interval, and clamps the result between a floor and a ceiling so funding cannot swing without limit.
4. Settlement. At each funding time (commonly every 8 hours), every open position pays or receives notional x funding rate.

On many venues, a calm market settles near a small baseline such as 0.01% per 8 hours, which is why 0.01% is often treated as a "neutral" reading. It is a convention, not a universal rule.

Note that funding is charged on notional, the full size of the position, not on the margin you posted. A 10,000 USD position at 10x leverage uses 1,000 USD of margin, but funding is calculated on the full 10,000 USD. That is why leverage magnifies funding costs relative to your capital.

How much does the funding rate cost? Worked examples

Funding looks tiny as a percentage, so it helps to convert it into money. Assume a 10,000 USD notional position and 8-hour funding (three settlements per day, 21 per week).

Example 1: 0.01% per 8 hours (a calm market)

• Per period: 10,000 x 0.0001 = 1 USD
• Per day: 1 x 3 = 3 USD
• Per week: 1 x 21 = 21 USD

Example 2: 0.03% per 8 hours (crowded longs)

• Per period: 10,000 x 0.0003 = 3 USD
• Per day: 3 x 3 = 9 USD
• Per week: 3 x 21 = 63 USD

With 1,000 USD of margin (10x), 63 USD a week is 6.3% of the margin before any price move. A long that is right about direction but slow to pay off can still lose money once funding is counted.

If the rate is negative and you are long, the same arithmetic works in your favour: you receive the payment.

Is a high funding rate bullish or bearish?

A high positive funding rate shows that longs are paying a lot to stay long, which means bullish positioning is crowded. It is not, by itself, a reliable bullish or bearish signal. Crowded positioning can persist for a long time while price keeps rising.

The chart below shows an illustrative four-day path of 8-hour funding. It starts near 0.010%, climbs to 0.031% as longs crowd in, turns negative to -0.012% when shorts take over, and then returns near zero.

How traders typically read funding:

• Rising positive funding with rising price: demand for leveraged longs is strong.
• Extreme positive funding: many longs are paying to stay in. If price stalls, those longs may close or be forced out, which can accelerate a drop. Read more on forced exits in what is liquidation in trading.
• Negative funding during a decline: shorts are crowded. A sharp bounce can force them to cover, similar to a short squeeze.

Funding is most useful alongside open interest: rising open interest with high positive funding means new leveraged longs are entering. Neither tells you when price will turn.

What is funding rate arbitrage?

Funding rate arbitrage, often called a cash-and-carry or basis trade, is a strategy that aims to collect funding while staying roughly neutral on price. In general terms, a trader buys the coin on the spot market and opens an equal-sized short on the perpetual. Price moves on the two legs largely offset, and while funding is positive the short leg receives payments.

It carries real risks:

• Funding can flip. If the rate turns negative, the short leg starts paying instead of receiving.
• Liquidation of one leg. The short perpetual is leveraged. A sharp rally can push it toward liquidation before the trader moves collateral, breaking the hedge. Exchanges typically use the mark price for this, but fast moves still happen.
• Execution costs. Fees, slippage and spreads on four trades (open and close both legs) can wipe out a small funding yield.
• Venue risk. Funds on exchanges can be exposed to outages or withdrawal freezes.

The return is compensation for these risks, not a guarantee.

How do you factor the funding rate into a trade?

Treat funding as a holding cost (or credit), like a fee that grows with time. A simple routine:

1. Check the current rate and the next settlement time before opening a position on a perpetual.
2. Estimate your holding period in funding intervals. A two-day hold at 8-hour funding is six settlements.
3. Convert to money: notional x rate x number of settlements. At 0.03% on 10,000 USD for six settlements, that is 18 USD.
4. Compare it with your target and your stop. If the expected funding cost is a meaningful share of your target profit, the trade needs a bigger edge or a shorter hold.
5. Size for it. Include expected funding in your risk budget. The risk management guide covers position sizing in detail.
6. Re-check during the trade. Funding can change at every interval, so a cheap hold can become expensive.

Common mistakes: judging funding by its percentage instead of its money value, and forgetting it is charged on notional rather than margin.

Crypto derivatives are high risk. Broker disclosures and academic studies consistently find that most retail day traders lose money, and leverage makes losses arrive faster.

How does Velotrade handle overnight costs?

Velotrade, a multi-asset prop trading firm offering simulated evaluations, does not charge a variable funding rate. According to the Velotrade FAQ, the overnight rate is a flat 0.05% of notional value. For crypto it applies to any position still open at 00:30 UTC and is charged every day, including weekends. The rate is the same whether you are long or short, so it does not flip with sentiment and is never received.

Using the same 10,000 USD position: 10,000 x 0.0005 = 5 USD per day held through 00:30 UTC, or 35 USD over seven days. Commission on crypto is separate at 0.03% per side. A trade opened and closed before 00:30 UTC pays no overnight charge.

For price comparison, the Velotrade FAQ points traders to the matching KuCoin USDT perpetual symbols on TradingView. Crypto trades 24/7 across 100+ instruments; see the crypto page and the instruments page for leverage per coin.

How does this apply in a prop trading evaluation?

Holding costs matter more in an evaluation because the limits are fixed in dollars. The daily loss limit resets every day at 00:30 UTC and is set from the higher of your balance or your equity at that time (CLASSIC 2-Step 5%, CLASSIC 1-Step 4%, PRO 1-Step 3%). The maximum drawdown is static, a fixed dollar floor that does not move.

Overnight charges are deducted from the trading account, so a multi-day swing trade should budget for them just as it would for funding on an exchange. There is no time limit on the evaluation, so there is no pressure to hold longer than the setup justifies. Compare how evaluation limits differ from margin-based leverage in funded trading vs leverage trading, and see the available challenges.

Can AI help with funding rate analysis?

AI tools can help screen many contracts for unusual funding readings, analyse your journal to see how much holding costs reduced your results, and support backtesting trading strategies that include funding as a cost.

AI does not remove risk. Extreme funding can stay extreme, and no model knows when a crowded trade will unwind. Treat AI trading signals as one input and keep the decision and sizing a human judgement.
