The world of cryptocurrency derivatives continues to evolve, and one of the most widely used instruments—perpetual contracts—is seeing significant improvements on leading platforms. Among them, OKEx (now rebranded as OKX) has recently implemented a major upgrade to its perpetual contract tiered margin system, significantly increasing user position limits while reducing margin requirements and improving leverage efficiency.
This strategic adjustment not only enhances trading flexibility for individual users but also strengthens overall market liquidity—a win-win development for traders and the broader crypto ecosystem.

Understanding Tiered Margin in Perpetual Contracts
Perpetual contracts have become the go-to derivative product in digital asset trading due to their unique advantages:
- No expiry or settlement
- Flexible long and short positions
- Adjustable leverage levels
- Multiple order types
- Broad selection of underlying assets
To manage risk across varying position sizes, exchanges use a tiered margin system, where larger positions fall into higher tiers with different parameters such as:
- Maximum position size per tier
- Initial margin rate
- Maintenance margin rate
- Maximum available leverage
As traders move up the tiers (i.e., increase their position size), the maintenance and initial margin rates typically rise, while the maximum allowable leverage decreases—this is designed to control systemic risk.
However, OKEx’s latest update flips this trade-off in favor of users by increasing position thresholds across key tiers, effectively allowing more exposure with less capital and reduced risk of liquidation.
What Changed? Key Updates to Tiered Margin Rules
In July 2020, OKEx announced an overhaul of its tiered margin structure for both coin-margined and USDT-margined perpetual contracts. While the exact date is no longer relevant, the impact of this change remains significant for active traders.
The update affected multiple major cryptocurrencies, including BTC, ETH, and others. Though specific tables were included in the original announcement, the core outcome was clear: higher tier thresholds mean lower effective margin rates and higher leverage availability at equivalent position sizes.
Let’s break down what this means with a real-world example.
Real Example: Opening a 20 BTC Position in BTCUSDT
Suppose a trader wants to open a 20 BTC position in the BTCUSDT perpetual contract. On OKEx, each contract represents 0.01 BTC, so 20 BTC equals 2,000 contracts.
Before the update:
- Maximum leverage: ~66.66x
- Initial margin required: ~0.3 BTC
- Maintenance margin rate: 1%
After the update:
- Maximum leverage increased to 100x
- Initial margin reduced to just 0.2 BTC
- Maintenance margin rate cut in half to 0.5%
This means:
- The trader needs 33% less capital upfront
- The liquidation price moves further away, reducing risk
- More room for market fluctuation without triggering auto-liquidation
- Greater profit potential from the same capital base

Competitive Edge: OKEx vs Other Major Exchanges
How does OKEx compare to rivals like Binance and Huobi under similar trading conditions?
Let’s analyze a scenario involving an 8,000-contract position in ETHUSDT, with each contract valued at 0.1 ETH. That’s a total exposure of 800 ETH, or approximately **$160,000** at $200 per ETH.
| Parameter | OKEx | Binance | Huobi (approx.) |
|---|---|---|---|
| Initial Margin Rate | ~3.125% | 4% | ~3.5% |
| Max Leverage | 32x | 25x | ~28x |
| Effective Maintenance Margin Rate | ~1.25% | ~1.67% | ~1.5% |
Note: Data derived from public tiered margin schedules and calculations based on position size.
From this comparison:
- OKEx requires the lowest initial margin
- Offers the highest maximum leverage
- Has the lowest maintenance margin rate, meaning a wider buffer before liquidation
For active traders, especially those using algorithmic or high-frequency strategies, these differences translate into tangible advantages—lower costs, better capital efficiency, and enhanced risk control.
Why This Matters for Traders and Markets
1. Improved Capital Efficiency
Traders can now deploy smaller amounts of collateral to achieve the same (or larger) positions. This opens up opportunities for mid-sized and retail traders to access levels of exposure previously reserved for institutional players.
2. Reduced Liquidation Risk
With lower maintenance margin rates, positions are less likely to be liquidated during volatile market swings—critical during events like Bitcoin halvings or macroeconomic shocks.
3. Enhanced Market Liquidity
Higher position limits encourage larger traders (whales and funds) to operate directly on the platform instead of relying on OTC desks. This increases order book depth and reduces slippage for all users.
4. Greater Accessibility
By lowering barriers to entry—both in terms of capital and risk tolerance—OKEx makes advanced trading tools more accessible to a global audience.
User-Centric Innovation: A Culture of Feedback
Beyond technical upgrades, OKEx has long emphasized user experience. Former CEO Jay Hao was known for actively engaging with the community via social media, treating every piece of feedback as a potential product improvement.
This “everyone is a product manager” philosophy has driven iterative enhancements across the platform—from UI/UX refinements to advanced risk engine optimizations.
Such responsiveness builds trust and loyalty in an industry where transparency and reliability are paramount.
