To safeguard users during periods of significant market volatility, such as a blockchain fork, exchanges often adjust their contract tier rules. This article explains the rationale behind such adjustments and provides detailed insights into managing associated risks effectively.
Key Adjustments to BCH Contract Tiers
The tier adjustments primarily target various BCH contract types, including both perpetual and delivery contracts, quoted in USDT and USD. The goal is to mitigate the risks of auto-deleveraging and loss sharing by modifying maintenance margin rates, initial margin requirements, and maximum leverage levels.
BCHUSDT Perpetual Contract Adjustments
The revised tier structure for BCHUSDT perpetual contracts introduces new thresholds for position sizes and corresponding margin requirements.
- Tier 1: Positions from 0 to 400 contracts now require a 3.00% maintenance margin and a 4.00% initial margin, allowing up to 25x leverage.
- Tier 2: Positions between 401 and 4,000 contracts require a 3.50% maintenance margin and a 4.50% initial margin, permitting up to 22.22x leverage.
- Higher Tiers: For larger positions, each subsequent tier increases the position size threshold by 8,000 contracts. The margin rates incrementally rise by 0.5% per tier, consequently reducing the maximum available leverage.
BCHUSD Perpetual Contract Adjustments
Similar adjustments have been applied to the USD-quoted perpetual contracts to ensure consistency in risk management.
- Tier 1: Covers 0 to 1,000 contracts with a 3.00% maintenance margin and 4.00% initial margin for 25x leverage.
- Tier 2: Applies to 1,001 to 10,000 contracts, increasing margins to 3.50% and 4.50%.
- Progressive Tiers: Larger positions see tier thresholds increase by 20,000 contracts each, with margin requirements rising by 0.5% per level.
BCHUSDT Delivery Contract Updates
Delivery contracts for BCH paired with USDT have also been updated to reflect the new risk parameters.
- The initial tier now covers 0 to 200 contracts with a 3.00% maintenance margin.
- Subsequent tiers increase the contract threshold by 10,000 per level and margin rates by 0.5%, systematically reducing leverage for larger holdings.
BCHUSD Delivery Contract Updates
The adjustments for USD-margined delivery contracts mirror those of their perpetual counterparts.
- The structure begins with a 0-1,000 contract tier at 3.00% maintenance margin.
- Each new tier adds 20,000 contracts to the range and 0.5% to the margin rates, ensuring a graduated approach to risk.
Proactive Risk Management for Traders
Following these adjustments, the maintenance margin rate for some existing positions may increase. Traders are strongly advised to take proactive steps to manage their risk exposure.
- Reduce Leverage: Consider partially closing or fully closing positions to lower your account's overall leverage.
- Add Collateral: Depositing additional funds to increase your margin balance can help avoid margin calls.
- Monitor Closely: Keep a vigilant eye on your positions, especially during high-volatility events like a fork.

Frequently Asked Questions
What is a contract tier system?
A tier system organizes open positions into brackets based on their size. Each tier has specific margin requirements, with larger positions typically requiring a higher margin percentage. This protects both the trader and the exchange from excessive risk.
Why were these adjustments made specifically for BCH?
These changes were implemented in anticipation of the Bitcoin Cash (BCH) fork. Hard forks can create extreme price volatility and uncertainty, significantly increasing the risk of liquidations. The adjusted tiers help cushion the market against these potential effects.
How do I know what tier my position is in?
Your exchange's trading interface or account section for futures and perpetual swaps will display your current open positions and their corresponding tier level, along with the associated margin requirements.
Will these tier changes be permanent?
Not necessarily. While some changes may remain, exchanges often revert to standard tiers or make further adjustments once the period of high volatility has passed and market conditions have normalized.
What is the difference between initial and maintenance margin?
The initial margin is the amount required to open a leveraged position. The maintenance margin is the minimum amount of equity that must be maintained in the position to avoid being liquidated. The maintenance margin is always lower than the initial margin.
Can I still open large positions after these changes?
Yes, but it will require more capital. The tier adjustments mean that larger positions will need a higher initial margin, effectively lowering the maximum leverage available for big trades.
