OKX to Adjust Initial and Maintenance Margin Calculations for Futures in Hedge Mode

Published on Sep 21, 20263 min read

To improve your trading experience and optimize capital efficiency in hedge mode, OKX will adjust the calculation methods for the Initial Margin Requirement (IMR) and Maintenance Margin Requirement (MMR) for futures under cross-margin hedge mode.This adjustment applies to Futures mode accounts and Multi-currency Margin mode accounts. Isolated margin mode is not affected by this adjustment.


This adjustment will be gradually rolled out starting on September 22, 2026, and is expected to be fully effective for all users by October 12, 2026.


1. Calculation of Position and Opening Order Initial Margin in Hedge ModeAfter the adjustment, in hedge mode, the system will no longer simply add the margin requirements for the long and short sides together. Instead, it will calculate the margin requirement for each side separately and use the higher of the two as the final Initial Margin Requirement.


Updated calculation method

  • Long-side margin requirement = (Long position value + long opening order value) / leverage

  • Short-side margin requirement = (Short position value + short opening order value) / leverage

  • Initial Margin Requirement (IMR) in hedge mode = Max (Long-side margin requirement, Short-side margin requirement)

Impact of adjustmentThis adjustment helps reduce margin usage for users with hedged positions and opening orders, thereby improving capital efficiency.


2. Calculation of Position and Opening Order Maintenance Margin in Hedge ModeAfter the adjustment, in hedge mode, the system will no longer simply add the maintenance margin requirements for the long and short sides together. Instead, it will calculate the maintenance margin requirement for each side separately and use the higher of the two as the final Maintenance Margin Requirement.


Updated calculation method

  • Long-side maintenance margin requirement = (Long position value + long opening order value) × maintenance margin ratio

  • Short-side maintenance margin requirement = (Short position value + short opening order value) × maintenance margin ratio

  • Maintenance Margin Requirement (MMR) in hedge mode = Max (Long-side maintenance margin requirement, Short-side maintenance margin requirement)

Impact of adjustmentThis adjustment helps reduce maintenance margin requirements for users with hedged positions and opening orders, thereby improving capital efficiency.


Please note:

During the phased rollout, some users may gain access to the new margin calculation method earlier than others. Please refer to the account, position, and margin data displayed on the trading page or returned via the Open API.
