The Cash Account is the most basic type of account you can open with Interactive Brokers. It’s ideal for investors who prefer simplicity and are cautious about taking on debt:

  • Transaction Basis: Trades are executed using the available funds in the account. There’s no leverage available, meaning you cannot borrow funds or engage in short selling.

  • Settlement Period: After selling shares, the funds from the transaction will not be available for trading until after the settlement period, which typically lasts 2 days in the UK.

IBKR Reg T Margin Account

A step up in terms of flexibility and potential for higher returns, the Reg T Margin Account allows more experienced traders to leverage their investments:

  • Age and Deposit Requirements: Investors must be at least 21 years old and deposit a minimum of $2,000.
  • Leverage: This account type allows investors to borrow against the value of the securities in their account to open new positions or engage in short sales.

IBKR Portfolio Margin Account

For investors looking for even greater leverage and the ability to undertake riskier trades, the Portfolio Margin Account offers advanced features:

  • Capital Requirement: A significant initial investment of $100,000 is needed to open this type of account.
  • Enhanced Leverage: Provides higher leverage limits, enabling the execution of more aggressive trading strategies.
  • Additional Benefits: No custody fees are charged, and interest is paid on uninvested cash balances within the account.
