Direct Answer
Basis trading takes a position in the difference between a futures price and the spot price of the underlying, the basis, buying spot and selling futures when the basis is rich and expected to narrow, or the reverse when it is cheap, so the profit comes from convergence rather than from the direction of the asset. It tends to work when the mispricing is caused by flows rather than by information, such as speculative demand for futures, and the trader can hold to convergence at expiry. Convergence is certain at expiry but the path is not; leveraged basis trades have blown up in both Treasury and crypto markets when financing dried up.
Basis Trading
How Does Basis Trading Work?
Basis trading takes a position in the difference between a futures price and the spot price of the underlying, the basis, buying spot and selling futures when the basis is rich and expected to narrow, or the reverse when it is cheap, so the profit comes from convergence rather than from the direction of the asset.
The rules:
- Compute the basis as futures price minus spot, and compare it with the cost of carry (financing plus storage minus income) that explains it
- Enter when the basis deviates from fair carry by more than the trading costs
- Hold to expiry, when the basis converges to zero, or close when it has returned to fair value
- Account for margin on the futures leg and the funding of the spot leg
Worked example. A future at 101.50 against spot at 100.00 is a 1.50 basis; with fair carry of 0.80, the basis is $0.70 rich, which a basis trader captures by buying spot and selling the future to expiry. The inputs are illustrative numbers, not market data.
When it tends to work. It tends to work when the mispricing is caused by flows rather than by information, such as speculative demand for futures, and the trader can hold to convergence at expiry.
When it fails. It fails when the basis widens further before converging, forcing margin calls, and when the assumed carry (storage, financing, dividends) turns out to be wrong.
Main risk. Convergence is certain at expiry but the path is not; leveraged basis trades have blown up in both Treasury and crypto markets when financing dried up.
