A funding rate is a small payment that passes between traders on a perpetual futures contract every few hours, to keep the contract's price close to the real coin's price. When funding is positive, traders who are long pay traders who are short. When it's negative, shorts pay longs. The exchange doesn't keep it. On most exchanges it's quoted per eight hours, which makes it look tiny, and that's exactly why it catches people out.
What is a funding rate in crypto?
A perpetual future is a bet on a coin's price that never expires. We explain the whole product in how perpetual futures work. Because there's no expiry date, nothing forces the contract's price to meet the real price of bitcoin or ether at some point. Left alone, it would drift wherever the crowd pushed it.
Funding is the fix. Every few hours, the side that's pushing the contract away from the real price pays the other side. If everyone's piling into longs and the contract trades above spot, longs pay. That makes being long more expensive and being short more attractive, until the gap closes. It's a payment between traders, not a fee to the exchange.
You only pay or receive funding if you hold a position at the exact moment it settles. Close your trade a minute before and you skip it. Open one a minute after and you skip it too.
Positive vs negative funding: who pays whom
Positive funding is the normal state in crypto, because more people want leveraged exposure to prices going up than down. Negative funding is rarer. It usually turns up after a sharp fall, when traders rush to short and the contract slips below spot.
How funding is calculated
Every exchange has its own recipe, but most follow the shape Binance publishes. There are two parts. A fixed interest rate, set at 0.01% per eight hours on most Binance contracts. And a premium, which measures how far the contract has drifted above or below the spot price, averaged over the whole period rather than taken at one moment.
Binance then clamps the difference between the two, so small drifts don't change anything. Its own guide says that as long as the premium sits between -0.04% and 0.06%, funding comes out at exactly 0.01%. That's why you see 0.0100% on Binance's screen most of the time. Only when the crowd leans hard one way does the number move.
| Platform | How often funding is paid | Limits |
|---|---|---|
| Binance | Every 8 hours (00:00, 08:00, 16:00 UTC) on most contracts | Switches a contract to every hour if funding hits its cap; smaller contracts capped at ±2% |
| Hyperliquid | Every hour, at one eighth of the 8-hour rate | Capped at 4% an hour |
| Kalshi (US) | Every 8 hours | Capped at 2% per period |
Those intervals matter more than they look. The same 0.01% charged hourly instead of every eight hours costs eight times as much. Always check the interval on the contract page before you compare rates across exchanges.
What funding actually costs you
Funding is charged on the full size of your position, not on the margin you put up. That's the part that bites. Take a $10,000 long position, held all year:
| Funding per 8 hours | Per day | Per year (if it never changed) |
|---|---|---|
| 0.01% (Binance default) | $3 | $1,095, about 11% |
| 0.03% (busy market) | $9 | $3,285, about 33% |
| 0.10% (overheated) | $30 | $10,950, about 110% |
If you put up $1,000 at 10x to control that $10,000, the default rate alone eats about $1,095 a year, more than your whole deposit. Funding is the quiet reason leveraged longs that "were right in the end" still lose money.
Rob's take
Read the funding number as a daily bill, not a decimal. "0.03%" sounds like nothing. "$9 a day on a $10,000 position, whether the price moves or not" is what it actually is. If you wouldn't pay that rent to hold the trade for a month, don't open it.
Prefer to watch? The fee that eats leveraged trades, in under a minute.
Is a high funding rate bullish or bearish?
Both, which is why it's useful. A high positive rate tells you traders are paying heavily to be long. That's bullish sentiment. It also tells you the long side is crowded and expensive to hold, and crowded trades unwind violently. When the price dips, overleveraged longs get liquidated, their forced selling pushes the price lower, and the next layer gets liquidated too.
On 27 February 2024, with bitcoin near $57,000 and money pouring into the new US spot ETFs, annualized funding on Binance's bitcoin perpetual passed 100%, according to Velo Data and CoinGlass. Bybit was at 95%. Traders were paying more than their position's entire value per year for the privilege of staying long. Readings like that don't tell you the top is in. They tell you the market is running hot, and that a pullback will hurt.
Negative funding works the same way in reverse. Deeply negative funding means shorts are crowded. If the price bounces instead of falling, shorts get squeezed and have to buy back, which can send it up fast. That's why some traders treat strongly negative funding as a warning to bears, not a green light.
Funding is one gauge among several. Read it next to the price trend and the money flows covered in what moves bitcoin's price, and the cycle phases in how to read crypto market cycles.
Funding rate arbitrage, and its catch
If longs are paying shorts, why not just be short and collect? Because a plain short loses money if the price rises. So traders run what's called cash and carry: buy the coin, and short the same amount on a perpetual. The two positions cancel each other's price risk, and what's left is the funding payment. In a hot market that can mean double-digit yearly returns without betting on direction.
⚠ Red flag
"Market neutral" doesn't mean risk-free. Funding can flip negative and start charging you instead. The exchange holding your short can fail, freeze withdrawals or change its rules. And if the price spikes, your short can be liquidated even though the coin you hold went up by the same amount. Anyone selling you a "safe" funding yield is leaving those parts out.
Where to check funding rates
The most reliable figure is on the exchange's own contract page, next to the countdown to the next settlement. Binance, Bybit, OKX and Hyperliquid all show the current rate and the time left. For a view across exchanges at once, data sites such as CoinGlass and Velo publish live funding tables and history. Check three things before you trade: the current rate, which way it's running, and how often it's charged.
Questions people ask
What does a negative funding rate mean in crypto?
It means the perpetual contract is trading below the coin's spot price, so traders holding short positions pay traders holding long positions. It usually means more traders are betting on a fall than on a rise.
Is a high funding rate bullish or bearish?
Neither on its own. A high positive rate shows traders are paying a lot to be long, which is bullish sentiment, but it also means the trade is crowded and expensive. Crowded long trades are the ones that unwind fastest when the price dips.
How often is funding paid?
It depends on the exchange. Binance settles most contracts every eight hours, at 00:00, 08:00 and 16:00 UTC, and can switch a contract to every hour in extreme markets. Hyperliquid pays funding every hour.
Do I pay funding if I just hold the coin?
No. Funding only applies to perpetual futures positions. If you buy and hold the coin itself, or trade dated futures, there is no funding payment.
