Basis Trading on Hyperliquid
Basis trading focuses on the price relationship between spot and derivatives rather than outright direction, but the spread can widen, funding can change, and execution can dominate expected convergence.
Basis is the difference between the price of an asset in one market and the price of related derivative exposure. On Hyperliquid, traders can compare native spot with perpetual markets and build relative-value positions around that spread. A basis trade is not automatically delta-neutral or low-risk; its outcome depends on hedge ratios, funding, financing, convergence, and execution.
Perpetual basis is different from dated-futures basis
A dated futures contract has an expiry where futures and spot converge mechanically through settlement. A perpetual future has no expiry. Its link to spot comes through funding, mark/oracle systems, trader arbitrage, and market demand.
That means a perp basis can persist or change sign without a fixed calendar date forcing convergence.
Positive and negative basis
A perp trading above spot has positive price basis. A trader might buy spot and short the perp if the expected funding and convergence compensate for costs. A perp below spot creates the opposite relationship.
The funding rate is related to market imbalance but is not identical to the instantaneous basis. Treat them as separate variables.
Capital efficiency
Portfolio Margin can make relative-value structures more capital efficient because eligible spot and perp exposures are considered together. That efficiency is valuable only if the risk engine continues to recognize the hedge under stress.
Borrowing assets to create either leg introduces a financing rate that should be modeled as dynamically as funding.
Research workflow
Record spot price, perp mid, mark, oracle, funding, open interest, available depth, and relevant borrow rates at entry. Express basis in basis points, then track how each component contributes to PnL.
Backtests should use executable prices and historical funding rather than assuming trades occur at mid and the current funding rate persists.
Failure modes
Basis can widen before converging. One leg can become illiquid. Funding can reverse. Borrow availability can disappear. Large positions can cross margin tiers. Exchange or oracle behavior during a market disruption can differ from normal periods.
A basis trade should be sized for the path, not only the expected endpoint.
