What Is the Consequence of Missing a Funding Payment Due to Insufficient Margin?
If a trader's margin is insufficient to cover a negative funding payment (i.e. they are the paying side), the margin balance will be reduced, pushing the position closer to the maintenance margin level. If the account equity falls below the maintenance margin level as a direct result of the funding payment, the position will be immediately liquidated.
The funding payment is treated as a loss that directly depletes the available margin.
