Starting at 10:00 PM on August 9, 2023, OKX will implement a significant update to the way the maximum transfer amount is calculated for users operating under Portfolio Margin (PM) account mode. This adjustment is designed to improve capital efficiency and enhance user experience by allowing eligible option holdings to contribute toward transfer capacity.
The key change involves incorporating net positive option value as part of the collateral framework, enabling users with long options positions to potentially access higher transfer limits from their trading accounts. This marks a step forward in aligning risk models with real-world trading behaviors and asset valuations.
How Net Positive Option Value Supports Max Transfer Amount
Currently, within the PM account structure, net positive values from long option positions are not factored into collateral calculations. As a result, users holding in-the-money or deeply out-of-the-money options do not see an increase in their maximum allowable transfers—even if those options hold intrinsic or potential value.
After the update, OKX will begin recognizing positive net option value as valid collateral for the purpose of determining max transfer amounts. This means that profitable or valuable long options can now support increased liquidity access, giving traders more flexibility in managing their funds across different platforms or wallets.

However, to maintain robust risk management standards, several safeguards and valuation adjustments will be applied:
1. Liquidity Discount Coefficient
All long option values will be multiplied by a liquidity coefficient—a dynamic factor reflecting market depth and ease of execution. Options with lower trading volume or wider bid-ask spreads will receive a higher discount, ensuring only liquid and easily tradable assets contribute meaningfully to transfer capacity.
2. Delta-Based Discount for OTM Options
Out-of-the-money (OTM) options will undergo an additional valuation adjustment based on their Delta value, which measures sensitivity to price changes in the underlying asset. A discount coefficient between 0 and 1 will be applied depending on the Delta:
- Deeply OTM options (very low Delta) face heavier discounts.
- Near-the-money or high-Delta OTM options receive milder reductions.
This ensures that only options with a realistic probability of becoming in-the-money meaningfully influence transfer limits.
3. Predefined Cap on Option Value Contribution
To prevent overexposure, there will be a hard cap on the total net long option value that can be used to support transfers within each PM account. This limit is set at the account level and helps maintain system-wide stability during periods of extreme volatility.
These layered controls ensure that while users benefit from increased capital utility, systemic risks remain tightly managed.
Temporary Suspension During Market Volatility
OKX has built in a circuit breaker mechanism to automatically disable the option-value-based transfer feature when abnormal market conditions are detected in the options market—such as sudden spikes in implied volatility, order book imbalances, or flash crash scenarios.
During such events:
- The option value support for max transfer amount will be temporarily suspended.
- Users can still perform standard transfers based on traditional collateral (e.g., spot balances, futures PnL).
- Core account metrics—including Adjusted Equity, In Use Margin, and Cross Margin Ratio—remain unaffected.
Once risk indicators return to normal levels, the feature will be reactivated seamlessly for all PM users without requiring manual intervention.
This dynamic toggle ensures platform resilience while preserving user access to core functionality even under stress conditions.

Why This Update Matters for Traders
For active options traders, this change unlocks tangible benefits:
- Improved capital efficiency: Long options are no longer "dead" assets—they now contribute to usable liquidity.
- Greater financial agility: Higher transfer limits allow faster movement of funds for arbitrage, hedging, or external investments.
- Fairer valuation model: Recognizing time and intrinsic value in options aligns more closely with professional-grade risk frameworks.
Moreover, the inclusion of smart discounts and caps demonstrates OKX’s commitment to balancing innovation with safety—a critical consideration in decentralized and highly volatile digital asset markets.
