Hyperliquid Cross vs Isolated Margin Explained
Cross vs isolated margin on Hyperliquid: how each mode assigns collateral, how liquidation differs, and which fits which trade.
Direct answer
In isolated margin, a fixed amount of collateral backs one position, so a loss there is capped at that margin. In cross margin, the account's available balance backs all cross positions, which lowers liquidation risk on one trade but exposes the whole balance to a bad one. Pick isolated to ring-fence risk and cross to give positions more room.
In short
- 1Isolated margin caps the loss on one position at its assigned margin.
- 2Cross margin shares collateral across positions, so one loss can consume the account.
- 3Liquidation price depends on the mode, so a single-position calculator cannot model cross.
How does isolated margin work?
You assign a specific margin to the position. Adverse moves reduce that margin, and when what remains reaches the maintenance requirement the position can be liquidated. Other balances in the account are not touched.
How does cross margin work?
Cross positions draw on the shared account balance. Unrealized profit on one position can support another, and a loss on one reduces what protects the rest. The liquidation boundary is set by account-wide equity against account-wide maintenance, so it moves as other positions change.
Which should I use?
Isolated suits a speculative trade where you want a hard cap on loss, or a position you do not want other trades to affect. Cross suits hedged or correlated positions that benefit from sharing collateral. Neither lowers market risk; both change how fast a loss reaches liquidation.
- Isolated: defined risk per position, less capital efficiency.
- Cross: more capital efficiency, correlated blow-up risk.
- Re-check the mode before each order.
Why does it matter for calculators?
A liquidation estimate for one position only works for isolated margin because the margin is known. Cross and portfolio margin need the full account state. If the displayed price came from a simplified tool, treat it as an estimate.
Example: two accounts, same loss
Say an account holds $5,000. Trader A opens a $20,000 isolated long at 10x with $2,000 of margin. A bad move can take at most that $2,000, leaving $3,000. Trader B opens the same position in cross, backed by the whole $5,000.
Trader B has more room before liquidation, but if the position keeps falling the entire $5,000 is exposed. If B also holds a second correlated trade, a single move can reduce equity for both at once.
Common mistakes
Decide the maximum amount you are willing to lose on each idea, then pick the mode that enforces it.
- Switching to cross to avoid liquidation without recognising the larger loss it exposes.
- Opening several correlated cross positions and treating them as diversified.
- Using a single-position liquidation calculator for cross margin.
Practical next steps
Before your next order, open the position settings and confirm the margin mode, then write down the most you are willing to lose on this idea. If that number is smaller than your account balance, isolated margin with that amount is the cleaner way to enforce it. If you choose cross, keep a second figure: the account equity at which you will close everything by hand. The liquidation calculator on this site models the isolated case, and it will tell you plainly when a scenario needs full account data instead.
