How funding works
When the perp trades above the reference price, longs pay shorts; when it trades below, shorts pay longs. Payments settle periodically, so an account holding the receiving side accrues a steady income stream proportional to notional and the prevailing rate.
Rates are highest when positioning is most one-sided, which is exactly when the crowd is most confident. That is the source of the edge and also the source of the risk: you are paid to hold the uncomfortable side.
- Funding is paid on notional, so leverage scales the income and the risk together.
- Rates fluctuate; a position sized for a high rate can survive into a flat one.
- The income is small per interval and compounds only if the position survives.
- Delta management determines whether the strategy is income or a disguised directional bet.
