Funding rate: what it is, who pays, and what extremes mean

The funding rate is a small, regular payment between the buyers and the sellers of a perpetual future. When it is positive, longs pay shorts. When it is negative, shorts pay longs. It exists to keep the price of a contract that never expires close to the price of the coin itself. This page explains how it is set, how often it is paid, what it costs on a real position, and how to read it when it goes to an extreme. The funding extremes card on our channel reads exactly this number.

Perpetual futures in one paragraph

A perpetual future is a contract that tracks the price of a coin such as BTC or ETH, with leverage, and with no expiry date. A normal future settles on a set day, so its price is pulled back to spot as that day approaches. A perpetual never settles, so nothing pulls it back on its own. The first crypto perpetual was launched by BitMEX in 2016, and perpetuals are now the most popular crypto derivative: a 2022 sample in the academic literature puts their volume at roughly two to three times spot volume.

Why funding exists

Without an expiry, the contract price could drift far from spot whenever more people want to be long than short. Funding is the fix. If the perpetual trades above the index price, the rate turns positive and longs pay shorts. Holding a long gets more expensive, which pushes the contract back toward spot. If the perpetual trades below the index, the rate turns negative and shorts pay longs.

Two points that are often misunderstood:

• The exchange does not keep the money. Binance, OKX and others state that funding is transferred directly between traders, with no fee taken.
• You only pay or receive if you hold a position at the funding time. Close before the timestamp and no funding changes hands.

The anchor is not perfect. Research on perpetuals finds that their prices can stay away from their theoretical value for long stretches, and that these gaps were larger in crypto than in comparable currency markets.

Who pays whom

How often it is paid

There is no single schedule. It depends on the exchange and the contract:

• Every 8 hours is the most common default. Binance and OKX settle at 00:00, 08:00 and 16:00 UTC by default.
• Shorter intervals exist. OKX lists 1, 2 and 4-hour settlements and moves a contract to a shorter interval, step by step, when the rate hits its cap or floor. Binance can switch a contract to hourly settlement after a settlement hits the cap or floor.
• Every hour on some venues. Hyperliquid pays funding hourly, at one eighth of a rate calculated on an 8-hour basis.

So always check the interval on the contract you hold. The same rate paid every hour costs eight times more per day than the same rate paid every 8 hours.

How the rate is calculated

The large exchanges use the same recipe, with two parts:

1. An interest component. A fixed base rate, usually 0.01% per 8 hours (0.03% a day) on Binance, OKX and Hyperliquid.
2. A premium component. A measure of how far the perpetual trades from the index, averaged over the funding period.

They are combined with a clamp: funding rate = premium + clamp(interest − premium, −0.05%, +0.05%). In plain words, when the premium is small, the clamp swallows it and the rate stays at the 0.01% base. On Binance this holds for any premium between −0.04% and +0.06%. Only when the premium moves outside that band does the rate move with it.

On top of that, each exchange sets a cap and floor per contract. Binance ties many of them to the contract's maintenance margin; Hyperliquid caps funding at 4% per hour. When a contract settles more often than every 8 hours, the rate is scaled down to the shorter period.

What it costs on a position

The payment is the position's notional value times the rate: funding = position value × funding rate. Note that it is the full position, not the margin you posted.

A worked example, on a $10,000 BTC long with 8-hour funding:

At the base rate that is about 11% of the position per year. If the position was opened with $1,000 of margin at 10x leverage, the same $90 a month is 9% of the margin every month. At 0.10% it is 90% of the margin in 30 days, before any price move. Funding is a cost like any other: size it in before you open the trade, not after.

What extremes tend to mean

A rate far above the base means many traders are paying a lot to stay long with leverage. A rate deep below zero means many are paying to stay short. Either way, the useful reading is crowded positioning: one side is large, and it is paying to stay there.

Crowded positioning matters because leveraged positions can be forced out. Research from the Bank for International Settlements on the gap between crypto futures and spot finds that it is driven mainly by smaller, trend-chasing investors seeking leveraged upside, and that a high gap has historically come before price crashes. That is evidence about risk, not a timer.

What an extreme rate does not tell you:

• It is not a forecast. A crowded long can stay crowded, and the price can keep rising while longs keep paying, for days or weeks.
• It does not say who is right. Funding measures where the leverage sits, not whether that view is correct.
• It is one venue at a time. Rates differ across exchanges and contracts, and an hourly rate is not comparable to an 8-hour rate until you put them on the same basis.

That is why we pair funding with other reads. Spot bitcoin ETF flows show what unleveraged money is doing: two different reads on positioning. Scheduled supply events such as token unlocks are context a funding number will not show.

Where you can trade perpetuals

Access to perpetual futures depends on where you live and on the exchange's licences. If you are in the EU, check first where EU traders can legally trade perps.

FAQ

What is the funding rate in crypto?

It is a periodic payment between longs and shorts on a perpetual future. It keeps the contract price close to the spot index, because the contract has no expiry date to pull it back.

What does a negative funding rate mean?

It means the perpetual is trading below the index, so shorts pay longs. It usually reflects strong demand for short positions. It does not by itself mean the price will rise.

How often is funding paid?

Most often every 8 hours, at 00:00, 08:00 and 16:00 UTC on Binance and OKX by default. Some contracts settle every 1, 2 or 4 hours, and some venues, such as Hyperliquid, pay every hour.

Is a high funding rate bullish or bearish?

Neither on its own. It shows that many traders are long with leverage and paying for it. That crowding can unwind sharply, but it can also last. Treat it as a read on positioning and risk, not on direction.
