Hyperliquid Isolated vs Cross Margin: Which Should You Use?

What Is Isolated Margin on Hyperliquid?

Isolated margin means you assign a fixed amount of USDC collateral to a single position. That collateral — and only that collateral — backs the trade. The rest of your account balance is completely walled off.

How it works in practice: You have $10,000 in your Hyperliquid account and want to open a 10x long on ETH. You set isolated margin and allocate $2,000 as margin, giving you a $20,000 notional position. If ETH drops far enough to trigger liquidation, you lose $2,000. Your remaining $8,000 is untouched.

This is the margin mode you should start with. The loss ceiling is explicit and predetermined — there are no surprises. You know the worst case before you click "Buy."

When isolated margin liquidation triggers:

1. The mark price moves against your position.
2. Your unrealized loss consumes the allocated margin down to the maintenance margin level.
3. Hyperliquid's liquidation engine closes the position automatically.
4. You lose the isolated margin. The rest of your account is unaffected.

What Is Cross Margin on Hyperliquid?

Cross margin pools your entire USDC balance as shared collateral for all positions running in cross mode. Every cross-margin position draws from — and contributes to — the same margin pool.

How it works in practice: Same $10,000 account, same 10x long ETH at $20,000 notional. But now you also have a 5x short SOL position worth $15,000. In cross mode, both positions share the full $10,000 balance. If your ETH long is profitable while SOL drops, the ETH gains offset the SOL losses in real time, keeping your overall margin healthy.

That sounds efficient — and it is. Cross margin gives you a larger buffer against liquidation on any individual position because the entire account balance absorbs losses. But the tradeoff is severe: if the market moves hard against multiple positions at once (a correlation shock), the losses compound against the same shared pool and can wipe out everything.

When cross margin liquidation triggers:

1. Losses across all cross-margin positions reduce total account equity.
2. Account equity falls below the combined maintenance margin requirement.
3. The liquidation engine closes the largest loss-making position first.
4. If that is not enough to restore the margin ratio, it continues closing positions until the account is above maintenance or fully liquidated.

Which Should You Choose? Practical Guidance

The right margin mode depends on your trading style and experience level. Here are three common scenarios with clear recommendations.

Scenario 1: Single Directional Trade (Use Isolated)

You have $5,000 in your account and want to go 10x long on BTC because you expect a breakout. You are risking $1,000 on this trade.

• Set isolated margin with $1,000 allocated.
• Your $10,000 notional BTC position has a liquidation price roughly 9.5% below entry.
• Worst case: you lose $1,000. Your remaining $4,000 is safe.
• Place a stop-loss above the liquidation price to exit with a smaller, controlled loss.

This is the correct default for any trade where the thesis is independent and directional. There is no reason to risk your entire account on a single idea.

Scenario 2: Hedged Pair Trade (Cross Can Work)

You are long BTC and short ETH — a spread trade betting that BTC outperforms ETH. Both legs move together most of the time, so losses on one are partially offset by gains on the other.

• Cross margin lets the unrealized PnL from both legs net against each other.
• Your effective margin requirement is lower because the positions are inversely correlated.
• If the spread moves in your favor, you never risk liquidation on either leg individually.

Cross margin is defensible here because the positions are designed to hedge each other. The cascade risk is lower (though not zero — correlation can break during black swan events).

Scenario 3: Multiple Independent Altcoin Positions (Use Isolated)

You are long DOGE, long AVAX, and short LINK — three unrelated trades with different theses. These positions are not hedging each other. In cross margin, a flash crash in DOGE could drain margin from AVAX and LINK, liquidating positions that were otherwise healthy.

• Set isolated margin on each position with a defined risk budget.
• If DOGE gets liquidated, AVAX and LINK are completely unaffected.
• Total risk is the sum of your three isolated allocations — never more.

How to Set Your Margin Mode

On app.hyperliquid.xyz, click the leverage chip above the order panel (it shows your current leverage, e.g. "5x"). A modal opens with two toggles — Cross and Isolated — plus a leverage slider. Select your preferred mode, set the leverage level, and confirm. The setting applies per market, and you must choose before opening a position. To switch modes on an existing position, close it first and reopen with the new mode.

For a full step-by-step walkthrough of the leverage modal, see the leverage guide. If you are new to perpetual futures, start there.
