Cash accounts at Interactive Brokers (IBKR) are not allowed to have a negative balance in any currency. This policy is in place to maintain account stability and comply with regulatory requirements for cash accounts. To prevent negative balances, IBKR has implemented the following measures:
- Automatic Currency Conversion (AutoFx):
- If a withdrawal or transaction would result in a negative balance in one currency, the system automatically attempts to convert funds from other currencies available in the account.
- This conversion appears as a currency pair transaction in your account activity.
- Transaction Rejection:
- In cases where there are insufficient funds across all currencies in the account to cover a transaction, the system may reject the transaction to maintain a non-negative balance.
- Proactive Balance Management:
- The system continuously monitors account balances to ensure they remain positive across all currencies.
These preventive measures help ensure that your cash account always maintains a positive balance, providing financial stability and adhering to regulatory standards. It is important to keep track of your account balances in various currencies and ensure sufficient funds are available for your intended transactions.
