Cross margin shares one collateral balance across all positions; isolated margin limits each position to its own collateral. How each works, with an example.

Cross margin uses your whole account balance as shared collateral for every open position, while isolated margin ring-fences a fixed amount of collateral for each position separately. The choice decides how much you can lose when a single trade or loan goes wrong.
Margin is the collateral you post to open a leveraged trade or take a loan. The two modes differ in how far a loss can spread.
Isolated margin: each position has its own collateral bucket. If it is liquidated, you lose that bucket and nothing else. Cross margin: one shared pool backs everything, so profits on one position can keep another alive, but a big enough loss can consume the entire balance.
The same idea appears in DeFi lending. In an isolated market, a risky asset can only be borrowed against inside its own pool, so a problem stays contained. In a cross (global) market, all your deposits count together toward one borrowing limit and one health factor.
Perpetual futures venues usually let you pick per position; our perp DEX explainer covers how margin and funding interact there.
Say you have 10,000 USDC on a trading account and open a 10x long worth 10,000 USDC of BTC.
Isolated: you assign 1,000 USDC as margin. A drop of roughly 10% (a little less once maintenance margin is counted) liquidates the position. You lose about 1,000 USDC; the other 9,000 is untouched.
Cross: all 10,000 USDC backs the same position, so it survives a much larger drop before liquidation. But if BTC keeps falling, losses keep coming out of the whole balance, and a severe crash could wipe most of the account. More room to breathe, more to lose.
In lending, isolated markets protect lenders from a single bad collateral asset, while cross markets give borrowers more flexibility. Either way, understanding how DeFi liquidations work matters more than the mode you choose.
JewelSwap's money markets on MultiversX were designed with both isolated pools and a global (cross) lending pool, explained in our isolated and cross lending guide. Supply and borrowing on those markets are currently paused, so treat this as a description of the design, not a prompt to use them.
Cross margin is a mode where your entire account balance acts as shared collateral for all open positions, so gains in one can support another, but losses can draw on the whole balance.
Isolated margin caps the loss of each position at the collateral assigned to it, so it is safer for limiting damage. Cross margin is more capital-efficient and less likely to liquidate a single position early, but a bad move can cost the whole account.
In isolated mode, normally only the assigned margin is at risk. In cross mode, the whole account balance is at risk. In extreme gaps some venues can also socialise losses, so read the platform's rules.
