What Is MEXC Contract Margin Ratio? When Will Liquidation Occur?

MEXC Contract Margin Ratio Definition

1. The MEXC contract margin ratio represents the percentage of a trader’s position value that must be held as collateral in the form of initial margin.

2. This ratio is dynamically adjusted based on market volatility, asset type, and contract maturity—ranging from 0.5% for high-liquidity perpetuals to 15% for low-volume quarterly futures.

3. Margin ratio values are published in real time on MEXC’s official margin table and updated automatically when price thresholds or risk parameters change.

4. Traders can view their current margin ratio per open position through the “Positions” tab in the trading interface, where it appears alongside leverage settings and liquidation price indicators.

5. Unlike traditional exchanges, MEXC applies tiered margin ratios for larger positions, meaning higher notional sizes trigger incremental margin requirements to curb systemic exposure.

Liquidation Trigger Mechanism

1. Liquidation occurs when the maintenance margin level falls below the exchange-defined threshold—typically 0.5% for most BTC/USDT perpetual contracts.

2. The system calculates real-time equity against position margin using mark price, not last traded price, to prevent manipulation-induced liquidations.

3. Once equity drops to or below the maintenance margin requirement, the position enters forced liquidation queue and is closed at the best available market price within 200 milliseconds.

4. Partial liquidation may occur for multi-position portfolios where only undercollateralized contracts are terminated while others remain active.

5. A liquidation fee—usually 0.5% of the position’s notional value—is deducted from the remaining wallet balance before settlement.

Margin Call Threshold Behavior

1. MEXC does not issue manual margin calls; instead, it activates automatic margin replenishment alerts when equity reaches 110% of maintenance margin.

2. These alerts appear as pop-up notifications and email/SMS warnings, specifying exact USD-equivalent top-up amounts required to avoid liquidation.

3. Users may add margin manually via deposit or cross-margin transfer during active alerts, with updates reflected in real time across all positions.

4. If no action is taken within 60 seconds after alert activation, the system initiates partial closure starting from the highest-risk position.

5. Alert thresholds are recalculated every 3 seconds using live funding rate, index price, and order book depth data sourced from five independent price oracles.

Collateral Asset Eligibility

1. Only USDT, BTC, ETH, and stablecoins listed on MEXC’s Tier-1 collateral list are accepted for margin deposits without discounting.

2. Altcoin collateral undergoes haircut application—e.g., SOL is accepted at 70% of its marked value, ADA at 50%, and memecoins at 0%.

3. Cross-margin mode allows users to allocate multiple eligible assets simultaneously, with the system optimizing allocation based on volatility-weighted contribution.

4. Intraday collateral swaps are permitted, but each swap incurs a 0.02% processing fee and requires minimum 15-second confirmation delay.

5. Collateral valuation uses a 10-second time-weighted average price (TWAP) derived exclusively from MEXC’s internal matching engine—not external APIs.

Frequently Asked Questions

Q1: Does MEXC apply different maintenance margin levels for isolated versus cross-margin positions?Yes. Isolated margin positions maintain fixed maintenance thresholds defined at entry, while cross-margin positions use dynamic thresholds recalculated per wallet equity composition and asset correlation matrix.

Q2: Can a position be liquidated even if the mark price hasn’t crossed the liquidation price?Yes. During extreme slippage events, MEXC’s liquidation engine may trigger based on auction imbalance metrics—such as bid-ask spread widening beyond 3% over 5 consecutive ticks—regardless of mark price alignment.

Q3: Are liquidation orders executed on-chain or off-chain?All liquidation orders are executed off-chain via MEXC’s proprietary matching engine, with final settlement recorded on-chain only after full execution and reconciliation.

Q4: How does MEXC handle overlapping liquidations during flash crashes?The exchange deploys a priority queue sorted by position age and margin utilization rate, ensuring older positions with lower utilization are preserved while newer, highly leveraged ones are cleared first.
