Spot and Delivery-Futures Basis Arbitrage in Crypto-Margined Contracts
Summary
The article describes a cash-and-carry style trade using spot cryptocurrency and a short crypto-margined delivery futures contract. It monitors the futures premium over spot, buys spot, and opens a matching short to capture the basis; the legs can be closed when the premium narrows, or held toward delivery, when the article expects the contract price to converge to spot. It explains that inverse contract profits are nonlinear in the settlement currency and distinguishes those results from profit measured in dollars. Historical examples use ETH delivery contracts and show premium changes, while the proposed process includes comparing expiries and accounting for fees across four trades.
The article presents the hedge as low risk, but also identifies prolonged basis widening, API failures that leave a single leg open, poor liquidity, and slippage as risks. Its example data and opportunity discussion are historical, and convergence does not eliminate the cost or operational risks of carrying the position. Results depend on contract terms, execution, fees, and funding or transfer mechanics.
Key ideas
- The strategy pairs a spot purchase with a matched short in a crypto-margined delivery contract.
- A narrowing futures-to-spot premium can produce a gain before delivery if it exceeds trading costs.
- Inverse contract profits are nonlinear in coin terms and differ from dollar-denominated outcomes.
- Expiry choice, simultaneous execution, fees, liquidity, and slippage affect the trade.
- Basis widening, API failures, and single-leg exposure can create losses despite the hedge.
