Adjustment of Perpetual Swap Tiered Maintenance Margin Ratio Schedule

·

Cryptocurrency derivatives trading continues to evolve, with platforms enhancing risk management frameworks to support growing market demand. On July 16, 2020, a significant update was implemented to the tiered maintenance margin ratio schedule for selected perpetual swap contracts. This adjustment aimed to increase position limits and improve market liquidity—two critical factors for traders seeking flexibility and scalability in volatile markets.

By expanding risk thresholds across multiple assets, traders can now hold larger positions within the same margin tier, reducing the frequency of margin adjustments and enabling smoother execution strategies. This article breaks down the changes, explains key concepts, and highlights how these updates benefit active traders.

Understanding the Margin Ratio Adjustment

The core objective of this update was to enhance position scalability without altering the underlying risk parameters for each tier. In practical terms, users can now open larger positions before moving into a higher margin tier—meaning more trading capacity at lower maintenance costs.

Two types of perpetual swaps were affected:

For both categories, the basic risk limit (the starting contract volume for the first tier) and the step size to the next tier (increment per additional tier) were increased for a wide range of cryptocurrencies.

Coin-Margined Perpetual Swaps: Expanded Limits

The update significantly raised thresholds for several major altcoins. Notably:

These increases allow traders greater exposure before hitting stricter margin requirements, improving capital efficiency—especially for high-frequency or large-volume strategies.

USDT-Margined Perpetual Swaps: Strategic Upgrades

Stablecoin-margined contracts received even broader enhancements, reflecting growing demand for USD-pegged trading pairs:

These changes make it easier for traders to scale positions gradually while maintaining favorable leverage and margin conditions.

How Tiered Margin Calculation Works

To fully grasp the impact of this update, it's essential to understand how tiered margin systems function in perpetual swap trading.

Each tier defines:

Here’s how each parameter is calculated:

Maximum Contracts in a Tier

Formula:
Tier-1 max contracts + (number of additional tiers × step size)

Example (BTCUSDT, Tier 3):
1,000 + (2 × 10,000) = 21,000 contracts

Maintenance Margin Ratio

Formula:
Basic maintenance margin + (additional tiers × margin increment)

Example (Tier 3):
0.5% + (2 × 0.5%) = 1.5%

Initial Margin Ratio

Formula:
Basic initial margin + (additional tiers × initial margin increment)

Example (Tier 3):
1.0% + (2 × 0.5%) = 2.0%

Maximum Leverage

Formula:
1 / initial margin ratio

Example (Tier 3):
1 / 2.0% = 50× leverage

This structured approach ensures risk is proportionally managed as position size grows.
