What is funding on a perp?
Funding is the small periodic payment between longs and shorts that keeps a perp’s price glued to the real asset. It is a cost when you’re on the crowded side, an income when you’re not, and always a signal.
Funding is the recurring payment that keeps a perp’s price glued to the real market. It’s both a cost to hold and a signal about crowd positioning, and your CEO reads it as both.
A perp has no expiry date, which raises a quiet question: with no settlement to force honesty, what stops its price from drifting away from the real asset it tracks? The answer is a mechanism running every few hours, and once you can read it, it doubles as a market-mood gauge.
01The tether, explained
When the perp trades above the real price, the market is saying too many people want to be long. Funding then flows from longs to shorts, being long now costs a trickle, being short earns one, and the pressure nudges the perp back down toward reality. Trades below, and the flow reverses. No committee sets it; the gap itself does.
| Funding is… | Who pays whom | What it tells you |
|---|---|---|
| Positive | Longs pay shorts | Crowd leans bullish, longs are crowded |
| Negative | Shorts pay longs | Crowd leans bearish, shorts are crowded |
| Near zero | Almost nothing moves | Perp and reality agree; no lean to speak of |
02Funding as a cost
Hold a position on the crowded side and the trickle drains you continuously, small per interval, real over weeks. A thesis that needs a month to play out must beat the price move it expects and the funding it will bleed on the way. Any honest expected-value math on a perp includes that line.
03Funding as a signal
Extreme funding is the market wearing its heart on its sleeve. Heavily positive funding means the long side is packed, which is exactly when a disappointment unwinds fastest. Contrarian desks read stretched funding as a crowd leaning too far over one rail, and either stand aside or quietly take the paid side. Not a strategy on its own; a strong sentence in the argument.
04How your fund treats it
Your CEO reads funding both ways at once: as a recurring cost budgeted into every perp thesis before entry, and as a crowding signal weighed with the rest of the evidence. When a position’s funding drain starts outrunning its remaining edge, that is a reason to close, written, like everything else, in the day’s memo.
Funding compounds silently. A “free” position on the crowded side is paying rent every few hours, a fund that ignores it is losing money slowly on purpose.
What to remember
- Funding is the payment that tethers the perp to the underlying price.
- As a cost, it quietly eats into a position held too long.
- As a signal, it reveals which side the crowd is piling into.
- Your fund treats funding as information and expense at once.
