The cryptocurrency derivatives market continues to evolve, with increasing trading volumes, user participation, and liquidity shaping the future of digital asset trading. In line with this growth, OKX has announced a strategic update to its USDT-margined perpetual and delivery contracts, optimizing tiered position limit rules to enhance user flexibility and improve overall market efficiency.
Effective January 17, 2020 (HKT), OKX implemented changes to the tiered risk allowance system for USDT-margined futures and perpetual swaps. This adjustment allows traders to hold larger positions under the same maintenance margin rate tier, empowering both retail and institutional participants with greater scalability in their trading strategies.
Importantly, the transition was seamless—users experienced no disruption in trading activities during the 30-minute window from 17:00 to 17:30 (HKT). The core goal? To support growing demand while maintaining platform stability and risk control.
Understanding Tiered Position Limits
Tiered position limits are a critical risk management mechanism used by exchanges to manage large positions and mitigate systemic risk. These tiers define how much a trader can hold before facing higher margin requirements. As position size increases, so does the required margin, helping prevent excessive leverage and potential liquidations during volatile market conditions.
Under the revised framework, OKX increased base and incremental risk limits across multiple assets. This means traders can now scale their exposure further before moving into higher-risk tiers—without compromising on safety protocols.
Key Benefits of the Update:
- Higher position caps per tier
- Improved capital efficiency for active traders
- Enhanced liquidity across major trading pairs
- Consistent risk controls with dynamic scalability

Updated Rules for USDT-Margined Perpetual Contracts
The following outlines the updated parameters for USDT-margined perpetual contracts:
BTC (Bitcoin)
- Base Risk Limit: 50,000 contracts
- Incremental Step: +500,000 contracts per tier
- Base Maintenance Margin Rate: 0.5%
- Base Initial Margin Rate: 1.0%
ETH (Ethereum)
- Base Risk Limit: 100,000 contracts
- Incremental Step: +400,000 contracts
- Maintenance Margin: 1.0%
- Initial Margin: 2.0%
EOS, LTC, BCH, ETC, XRP, TRX, BSV
Each altcoin received proportional adjustments to align with market depth and volatility profiles. Notably:
- LTC: Base risk limit increased significantly compared to previous settings.
- TRX & BSV: Higher base thresholds reflect growing interest and trading volume.
- ETC & XRP: Moderate increments ensure balance between accessibility and risk control.
These updates allow traders to maintain larger open positions before hitting stricter margin requirements—giving more breathing room during volatile swings.
USDT-Margined Delivery Contracts: Expanded Capacity
Delivery (or futures) contracts also saw significant upgrades in their tiered structure:
BTC & ETH
Same base limits as perpetuals, ensuring consistency across product types.
Altcoin Enhancements
- LTC: Base risk limit now at 250,000 contracts (up from lower tiers previously)
- TRX: Jumps to a massive 500,000 base limit with 1,000,000 incremental steps
- BSV & BCH: Substantial increases support growing institutional interest
This expansion reflects OKX’s commitment to supporting diverse trading needs—from high-frequency scalpers to long-term hedgers.
How Tier Calculation Works
Understanding the math behind the tiers is essential for managing risk effectively. Here's how the system calculates key values:
Position Size per Tier
Formula:
First-tier limit + (Number of increments × Incremental step size)
Example (BTC Perpetual – Tier 3):
50,000 + (2 × 500,000) = 1,050,000 contracts
Maintenance Margin Rate
Formula:
Base rate + (Number of increments × 0.5%)
Example (Tier 3 BTC):
0.5% + (2 × 0.5%) = 1.5%
Initial Margin Rate
Formula:
Base initial rate + (Number of increments × 0.5%)
Example (Tier 3 BTC):
1.0% + (2 × 0.5%) = 2.0%
Maximum Leverage Available
Formula:
1 / Initial Margin Rate
Example (Tier 3 BTC):
1 / 2.0% = 50x leverage
Note: The maximum maintenance margin rate across all tiers is capped at 50.0%, providing a clear upper boundary for risk exposure.
Why This Matters for Traders
These adjustments aren’t just technical—they directly impact your trading performance.
1. More Room to Scale
With higher base and incremental limits, traders can deploy larger strategies without immediately entering high-margin tiers. This reduces friction in building positions over time.
2. Better Risk Management
By spacing out the tiers more efficiently, sudden jumps in margin requirements are minimized. This gives traders more time to react before reaching critical thresholds.
3. Increased Market Liquidity
Higher individual position limits contribute to deeper order books and tighter spreads—benefiting all market participants through improved execution quality.

Frequently Asked Questions (FAQ)
Q: When did the new tiered rules take effect?
A: The updated rules were implemented on January 17, 2020, at 17:00 HKT. Trading remained fully operational during the transition.
Q: Do these changes affect both perpetual and delivery contracts?
A: Yes, both USDT-margined perpetual and delivery contracts have been updated with revised tiered position limits and margin calculations.
Q: Will my current position be impacted by the change?
A: While your nominal position size won’t change, your effective margin rate and maximum allowable leverage may shift based on the new tier structure. Review your holdings to ensure alignment with updated thresholds.
Q: How do I calculate which tier my position falls into?
A: Use the formula: Base limit + (n × incremental step). Count how many times your position exceeds each step to determine your current tier.
Q: What happens if I exceed the top-tier limit?
A: Positions beyond the highest defined tier will be subject to the maximum maintenance margin rate of 50%. It’s advisable to monitor your exposure closely.
Q: Are there differences between coin-margined and USDT-margined contracts?
A: This update applies specifically to USDT-margined products. Coin-margined contracts follow separate risk frameworks.
