Initial Margin

What is initial margin?

Initial margin is the amount of collateral a trader must deposit to open a leveraged derivatives position, such as those covered in what are crypto perpetual futures. It’s essentially the “good-faith” buffer that helps ensure you can absorb some losses before your position becomes unsafe for the venue or counterparty. Initial margin is different from ongoing requirements like maintenance margin, which is the minimum equity you must keep after the position is open.

Initial margin crypto

In crypto markets, initial margin is the collateral you lock on an exchange or protocol to control a larger notional position using leverage. For example, if a platform requires 10% initial margin, opening a $10,000 position typically requires about $1,000 of collateral (before fees and any platform-specific adjustments). As the market moves, your account equity changes with unrealized profit and loss; if equity falls too far, you may breach maintenance margin and face liquidation or forced position reduction. Margin mode also matters: with isolated cross margin, you choose whether a single position is backed only by its own collateral (isolated) or by a broader pool of funds in your account (cross), which changes how initial margin and liquidation risk are managed.

IM perp

On perpetual futures, “IM” usually refers to the initial margin requirement for a perp position. Exchanges often express IM as a percentage (or its inverse as “max leverage”), and it can be dynamic: larger positions or riskier assets may require higher IM, and some venues use tiered schedules that increase margin as position size grows. Practically, IM on a perp sets your starting cushion—how far price can move against you before your equity approaches the maintenance margin threshold. If you open a perp with high leverage, your initial margin is small relative to the position, so even modest adverse moves can quickly erode equity. Funding payments and trading fees also affect equity over time, meaning a position can drift toward liquidation even without a large spot move if costs accumulate.

Why initial margin matters

Initial margin is a core risk control for traders and platforms because it limits how much loss can occur before a position must be closed or collateral is used. For traders, understanding initial margin clarifies the real risk of leverage: lower IM increases potential return on capital but narrows the margin for error and makes liquidation more likely once maintenance margin is approached. For exchanges and the broader derivatives ecosystem, IM reduces counterparty risk and helps keep markets orderly during volatility by ensuring positions are backed by sufficient collateral. If you’re learning what are crypto perpetual futures, initial margin is one of the first concepts to master because it directly determines position sizing, liquidation distance, and how resilient your account is to fast price swings.
