Withdrawing Collateral

Last updated: Jun 16, 2026

You can withdraw collateral that is not required for open positions, USDT debt, or account-health limits. In multicollateral accounts, each asset is withdrawn separately.

Available margin

You can only withdraw available margin, collateral not currently required to meet the margin requirements of your open positions.

available_margin = adjusted_account_value - required_margin

Adjusted Account Value includes collateral haircuts and PnL effects. The final max withdrawal also applies asset balance, the USDT cap, LTV and debt limits, fees, and any active limits shown in the app.

If you have no open positions and no USDT debt, most of your balance is generally available to withdraw, subject to those checks.

How to withdraw

  1. Go to exchange.synthetix.io and connect your wallet.
  2. Select the subaccount you want to withdraw from.
  3. Click Withdraw on the asset row you want to withdraw.
  4. Enter the amount to withdraw, up to the maximum shown in the app.
  5. Review any withdrawal fee and account-health warning.
  6. Confirm the transaction.

Withdrawals are sent to your connected wallet address on Ethereum Mainnet. Once the transaction is confirmed, your wallet and subaccount balances update.

Withdrawing with open positions

You can withdraw available margin while holding open positions. However:

  • Withdrawing reduces your health ratio and moves your liquidation price closer to the current market price.
  • You cannot withdraw collateral that would bring the account below maintenance margin.
  • Non-USDT collateral price moves can reduce your withdrawable amount even if your position PnL has not changed.

Withdrawing USDT with non-USDT collateral

USDT withdrawals are capped by both account health and the USDT available to send.

Your maximum USDT withdrawal can include:

  • Held USDT balance.
  • Positive unrealized PnL that can support a USDT withdrawal while the position remains open.

Non-USDT collateral value supports margin and trading, but it does not become withdrawable USDT unless you first convert it through Swap or otherwise receive USDT settlement from trading.

Debt and LTV constraints

If your USDT balance is negative after positive unrealized PnL is considered, the account has USDT debt. That debt is backed by non-USDT collateral.

Withdrawal amounts can be reduced to preserve:

  • Required margin for open positions.
  • The USDT cap for USDT withdrawals.
  • LTV and LLTV limits for non-USDT collateral backing USDT debt.
  • Any tier-based Max Borrow limit.

Your max withdrawal can be zero even when an asset has a balance. Common reasons include open positions reserving margin, USDT debt requiring collateral to stay in the account, or the asset fully backing debt with no spare margin budget.

To improve withdrawable amounts, consider reducing positions, swapping collateral to USDT to repay debt, or depositing additional collateral.

Withdrawal fees

Withdrawals can have a per-asset withdrawal fee. The fee is deducted from the amount received and is shown before you confirm.

Ethereum Mainnet gas is paid in ETH by your wallet for on-chain withdrawal transactions.

Transfers between subaccounts

Moving collateral between subaccounts follows the same type of availability checks as withdrawals. The source subaccount must keep enough collateral for open positions, USDT debt limits, and LTV constraints.

Collateral in one subaccount does not support positions in another subaccount. See Subaccounts for details.

Withdrawal delays

Withdrawals are processed on-chain with no additional delay beyond transaction confirmation. There is no withdrawal queue or waiting period.
