You clearly have a balance in your account, but the withdraw button is grayed out or shows as unavailable. In a Portfolio Margin account, this is a common misunderstanding: having "money" on paper does not mean all of it is available.
Funds are locked because the system has marked them as collateral for certain unsettled risks. Below we explain which risks are involved and how to check them.
1. Initial Margin for Open Positions
This is the most direct one. If you hold any position that requires margin in your Portfolio Margin account—such as perpetual contracts, delivery contracts, or short options—the system will set aside part of your total assets as initial margin.
- What happened: You have open contract or short option positions.
- Why it is locked: This money acts as a safety cushion for your current positions. If the price moves against you, this is the money that takes the loss first.
- How to check: On the account's "In Use" or "Margin Used" page, look for the amount used by "Contracts" or "Options".
2. Order Margin for Open Orders
This is easy to miss. You place a limit order that has not been filled yet—for example, using USDT to buy BTC. Even if the order has not gone through, the system may freeze some funds.
- What happened: You have unfilled orders on the spot or contract page.
- Why it is locked: The system needs to make sure you have enough funds to settle the order if it fills, so it reserves the money in advance.
- How to check: Go to the "Open Orders" page. Any order with a status of "Open" or "Pending" may be using funds. Cancel the order and funds should be released immediately.
3. Collateral Value Adjustment for Exchange Orders
This is a more hidden rule in Portfolio Margin mode. When you use an asset with a high collateral rate (like USDT) to buy an asset with a lower collateral rate (like some altcoins), the system may set aside extra funds.
- What happened: You placed a spot buy order for an asset whose collateral rate is lower than the asset you are using to pay.
- Why it is locked: The system expects that after the trade fills, the overall collateral value of your account may drop. It locks the difference in advance to prevent your account risk from suddenly rising.
- How to check: In the "In Use" details, you may see an amount under "Spot". This may include that extra reserve.
Risk Warning: Forcing a Withdrawal May Cause a Shortfall or Liquidation
Unsettled risk in a Portfolio Margin account is calculated dynamically. Even if you withdraw only part of your funds, it may cause your account's maintenance margin rate to fall below the threshold instantly and trigger forced liquidation. The platform is not trying to block you; the system is protecting you (and itself) from a shortfall. If a forced withdrawal pushes your account equity below zero, the risk fund may eventually have to cover the loss.
How to Check Before Withdrawing
Do not focus only on the withdraw button. Check these places on the account page first:
- "In Use" or "Margin Used": This is the total amount locked.
- Open Orders list: Look for unfilled orders. If there are any, cancel them first.
- Account maintenance margin rate: If this ratio is near the warning level (for example, 100%), the account risk is high and withdrawing is not recommended. Close positions or reduce open orders first. Once the "In Use" amount drops, the withdraw button should light up.
