Dear OKX users,
Since the launch of USDT-margined futures and perpetual contracts on OKX, we've observed steady growth in trading volume, user participation, and market liquidity. To further improve position limits and market depth, we'll implement adjustments to the tiered margin rules for USDT-margined contracts on January 17, 2020 (17:00–17:30 HKT). Trading will remain unaffected during this update.
Key Benefits of the Adjustment
- Higher position limits at equivalent maintenance margin tiers
- Optimized risk management parameters
- Enhanced liquidity across all contract types

Tier Calculation Formulas
| Parameter | Formula | BTC Example (Tier 3) |
|---|---|---|
| Position Limit | Base Limit + (Increment × Tier Count) | 50,000 + (2 × 500,000) = 1,050,000 |
| Tier Maintenance Margin | Base MM + (Tier Count × 0.5%) | 0.5% + (2 × 0.5%) = 1.5% |
| Tier Initial Margin | Base IM + (Tier Count × 0.5%) | 1.0% + (2 × 0.5%) = 2.0% |
| Maximum Leverage | 1 ÷ Tier Initial Margin | 1 ÷ 2.0% = 50.00× |
Note:
- All coins maintain a 0.5% incremental rate for both margin types
- Maximum maintenance margin capped at 50.0% for all coins
