Margin Requirement — New Calculation: April 28, 2022

Effective 29 April 2022, Interactive Brokers1 will implement a new methodology to measure margin requirements for accounts holding a concentrated position in a low cap stock(s), including all holdings under the same issuer.

New Methodology

Currently, margin requirements for accounts holding a concentrated position in a low cap stock are determined using a proprietary Value at Risk (VAR) methodology, which calculates the theoretical worst-case loss of the position, given a range of price and implied volatility changes. The price scanning range for a given security is the greater of an individual portfolio’s concentration margin rate and the result of a stress test that simulates a price change reflective of a $500 million decrease in market capitalization.

The new methodology applies the same VAR framework, but Interactive Brokers will apply the greater of the individual concentration margin rate or low cap stress test to each asset.

For example, below are two assets held in a single account, issued by the same issuer with the same value, where the market capitalization of the issuer is $715 million.

  • Asset A: Concentration rate is 100%
  • Asset B: Concentration rate is 30%

Under the present calculation, the margin requirement for the portfolio would be based on the $500 million decrease in market capitalization, or approximately 70% of the market value of the 2 assets. Under the new concentration methodology, Asset A minimum price scan would remain at 100% and Asset B would increase to 70%, with an effective margin rate of 85%.

Recommended Actions

To evaluate the new change’s full impact on your portfolio and ensure the accounts remains margin compliant, please see KB Article 2957: Risk Navigator: Alternative Margin Calculator, and/or from the margin mode setting in Risk Navigator, select “MARGIN 20220429”.

Accounts that are unable to carry a position under this new margin requirement are subject to liquidations to bring the account into margin compliance. Therefore, please make necessary adjustments to your portfolio to comply with Interactive Brokers’ new policy.
