Definition — Isolated margin is a way of structuring leveraged positions where each position has its own dedicated collateral, its own loan, and its own risk limits. If one position fails, only the collateral assigned to it is at stake — the rest of your account is walled off.
Why Does Margin Mode Matter?
When you trade with leverage, you're borrowing capital against collateral. The question every margin system has to answer is: which collateral? There are two standard answers, and they produce very different risk profiles.
Isolated Margin: One Position, One Wall
Under isolated margin, every position lives in its own compartment. You decide how much collateral to commit when you open it, and that number is your maximum loss on the position. A liquidation, if it happens, consumes only what's inside the compartment.
Cross Margin: One Pool, Shared Fate
Under cross margin, all positions draw on a single shared collateral pool. This is capital-efficient — a winning position can prop up a losing one — but it links everything together: one position moving sharply against you can drain the pool and pull healthy positions into the same liquidation.
Isolated vs Cross Margin at a Glance
Isolated margin | Cross margin | |
|---|---|---|
Collateral | Dedicated per position | Shared across all positions |
Maximum loss per trade | The collateral you assigned | Potentially the whole pool |
One position blows up | Others unaffected | Others can be dragged down |
Capital efficiency | Lower — collateral sits per position | Higher — collateral works everywhere |
Mental accounting | Simple: each trade is its own bet | Complex: everything interacts |
How Isolated Margin Works in Practice
On StableStock, leveraged spot runs exclusively in isolated mode. Each position's funds and risk are ring-fenced from your spot account and from your other leveraged positions. You fund a position by transferring USDT or USDC into your leverage account and assigning it to the trade; each position then carries its own LTV (loan-to-value) risk metric, its own warning line, and its own liquidation line.
That structural choice does something subtle for risk management: it converts one big, tangled question ("how risky is my account right now?") into several small, answerable ones ("how risky is this position?"). Each position's LTV tells you exactly where that trade stands, and acting on it — adding collateral, trimming, or adjusting leverage — affects that trade alone.
What Isolated Margin Does Not Do
Isolated margin caps the damage of any single position; it doesn't make leverage safe. Within its compartment, a leveraged position still amplifies losses as well as gains, can still be liquidated, and liquidation still carries costs. Isolation limits contagion — it does not limit the risk you chose to put inside the box.
Takeaway: Isolated margin gives every leveraged position its own collateral, its own risk lines, and its own worst case — one trade going wrong can't touch the rest of your account. It trades some capital efficiency for containment and clarity, which is why it's the default structure for StableStock's leveraged spot.
