Funding rate (perpetual futures)

How the rate is set

A perpetual contract never expires, so nothing forces it to converge to the spot price. The funding payment does that work: when the perpetual trades above the index of spot prices, the rate tends to be positive and longs pay shorts, which makes holding longs more expensive and shorts more attractive; below the index, the reverse.

Binance documents its formula for USDⓈ-M contracts as F = [average premium index P + clamp(interest rate − P, 0.05%, −0.05%)] ÷ (8 ÷ N), where N is the funding interval in hours. The premium index measures how far the impact bid and impact ask prices of the perpetual sit from the price index; the interest rate is fixed at 0.01% per interval, representing the difference between the cost of holding the quote currency and the base asset. The clamp means that when the premium is small, the rate settles at the interest rate.

A payment example

A long position with a notional value of 10,000 USDT at a funding rate of +0.01% pays 10,000 × 0.0001 = 1 USDT at the funding time; the shorts on the other side receive it. The exchange does not keep the payment: it passes between traders. Only positions open at the funding timestamp pay or receive. At a constant +0.01% every 8 hours, a long would pay three times a day, about 0.03% per day, which compounds to roughly 11% over a year of simple accumulation, a cost that a leveraged long carries on the full notional, not on the margin posted.

What the rate says, and what it does not

• A persistently high positive rate says that perpetual longs are paying to keep their positions: demand for leveraged longs exceeds shorts at the index price.
• It is a price of positioning, not a forecast; markets can keep rising with high funding or fall with it.
• Rates differ between exchanges and between contracts on the same exchange, because each has its own participants.
• Activity can shift around funding timestamps as positions are opened or closed to avoid or collect a payment.

In Senzoukria

The desktop reads Binance USD-M perpetual and Bybit linear perpetual trades and order books from public feeds for analysis, but it does not display funding rates, and nothing funding-related is presented as executed volume. Crypto charts are analysis only: there is no crypto order ticket and no crypto autopilot. When reading perpetual order flow around funding times, the exchange's own schedule is the reference, since intervals can differ by contract.
