Margin in an Interactive Brokers (IBKR) account refers to the amount needed to maintain positions and potentially borrow against eligible securities. It is important to note that having a margin account does not necessarily mean you are borrowing money. If you hold only long positions and your cash balance remains positive, you are not borrowing on margin.
IBKR offers two types of margin accounts:
- Reg T Margin (rules-based):
- Provides 4:1 potential leverage during the day
- Offers 2:1 leverage overnight
- Portfolio Margin (risk-based):
- Requires an account value of USD 110,000 or equivalent to request an upgrade to Portfolio Margin
- Offers up to 6:1 potential leverage depending on account composition
In a Risk Based Margin account, leverage is not guaranteed at a specific ratio. Margin requirements are calculated using various formulas based on factors such as Market Capitalization, potential loss of Concentrated positions, or Portfolio Margin rules.
How margin works in an IBKR account:
- Available cash in the required currency is used first for purchases.
- If insufficient cash is available, a margin loan is created automatically.
- This results in a negative balance in the respective currency.
- Interest is charged on any negative settled cash from a margin loan.
- IBKR does not automatically convert currency balances.
Margin loans can be created by:
- Purchasing securities without sufficient cash in the settlement currency.
- Withdrawing funds exceeding settled cash in the withdrawal currency.
- Incurring fees exceeding settled funds in the fee currency.
Margin can be used for new positions or cash withdrawals. Depositing currency reduces negative cash balances in that specific currency. It is important to understand that while margin accounts allow for potential leverage, they also come with risks. Users can choose between margin and cash accounts based on their trading needs and risk tolerance.
