What is delta neutral?
Delta neutral describes a portfolio holding long and short positions that offset each other's price directional movements, resulting in near zero net exposure.
How does it work?
Buy 1 Bitcoin. Sell a short futures contract for 1 Bitcoin.
If Bitcoin falls, the spot holding loses value and the short on perps gains roughly the same. If Bitcoin rises, the reverse.
You have removed the thing most crypto positions depend on, so you need a different source of yield.
Where the yield comes from
That source is the funding payment.
Perpetual futures have no expiry, so exchanges use a periodic funding payment to keep the perpetual price tethered to spot.
When the perpetual trades above spot, longs pay shorts. When below, shorts pay longs.
Holding spot and shorting the perpetual puts you on the receiving side whenever funding is positive.
Why funding is usually positive
Participants generally expect higher prices ahead, which pushes futures prices above spot.
This pattern is called contango, and in crypto it persists longer because of the high demand for leveraged long exposure, but persistent is not permanent.
Funding can flatten and it can invert.
This is why the asset of choice matters: it must have deep liquidity, and long periods of positive funding rates to be considered a good asset to execute a delta-neutral strategy on.
What delta neutral does not mean
- Not risk free. It removes directional price risk, not execution, liquidity, venue, margin, or funding risk.
- Not a guaranteed yield. Extended negative funding can produce negative yield.
- Not self-maintaining. Neutrality is held through systematic rebalancing, not assumed.
