What is Settlement (Funding)?
Settlement in perpetual futures is the discrete moment when the exchange applies the funding payment: it debits the side that owes funding and credits the side that receives it, based on the rate and each trader's position size at that timestamp — not continuously, but at fixed funding intervals.
Settlement is the event, not the rate. A perpetual contract quotes a funding rate continuously, but money only changes hands at the settlement timestamp that closes each funding interval (commonly every 8h, or every 1h on venues like Hyperliquid, dYdX, Pacifica and RiseX). At that instant the exchange looks at your open position size and the applicable rate, computes the payment, and moves it between longs and shorts. Hold the position through the timestamp and you settle; close one minute before and you owe or earn nothing.
The payment is size-based, not margin-based: funding = position notional × funding rate, applied at each settlement. When the rate is positive, longs pay shorts; when negative, shorts pay longs. The transfer is peer-to-peer between traders — the exchange is only the clearing mechanism, so a funding-arbitrage carry position that is long on one venue and short on another nets the two settlements against each other.
For funding arbitrageurs, settlement is where the strategy's yield actually accrues. The screener's predicted/annualized APR is an estimate of what future settlements will pay; the realized funding you bank is the sum of the discrete settlement amounts you were actually holding through. If your position turns over between two settlements, or you enter just after a settlement, you can carry price risk for hours before collecting a single payment.
Two subtleties bite most in practice. First, alignment: two venues on different funding intervals (say 8h vs 1h) settle at different clocks, so your realized carry is lumpy rather than smooth. Second, the rate that settles is the realized rate at the timestamp, which can differ from the predicted rate you saw when you opened — this is why a realistic backtester reconstructs PnL from actual per-settlement amounts rather than multiplying one snapshot rate by time.
Worked example — one 8h settlement on a BTC carry
- •Position: long 1 BTC on Venue A, short 1 BTC on Venue B, BTC ≈ $60,000 → notional $60,000 per leg.
- •Venue A funding rate this interval: +0.01% (longs pay). You are long → you PAY 0.01% × $60,000 = $6.00.
- •Venue B funding rate this interval: +0.03% (longs pay). You are short → you RECEIVE 0.03% × $60,000 = $18.00.
- •Net at this settlement: +$18.00 − $6.00 = +$12.00 collected for holding through the timestamp.
- •Annualized on the wider leg: 0.03% × 3 settlements/day × 365 = 0.03% × 1095 = 32.85% APR (before fees & slippage).
FAQ
What is settlement in perpetual futures funding?
It is the fixed moment at the end of each funding interval when the exchange actually transfers the funding payment between longs and shorts. The rate is quoted continuously, but cash only moves at these discrete settlement timestamps.
Do I pay funding if I close before settlement?
No. Funding is only charged or credited to positions open at the settlement timestamp. If you close even seconds before it, you neither pay nor receive funding for that interval — though you also lose that interval's carry.
Why does realized funding differ from the predicted APR?
The APR shown is annualized from a current rate snapshot, but each settlement applies the realized rate at its own timestamp, which drifts. Realized funding is the sum of those actual per-settlement amounts, so a backtester rebuilt from settlements is more accurate than rate × time.
How does settlement timing affect a funding-arb position?
Two legs on different funding intervals settle on different clocks, making realized carry lumpy. To bank a full interval's funding you must hold each leg through its own settlement timestamp, so entry timing relative to settlement changes how quickly the carry actually accrues.
