Portfolio margin

Portfolio margin is a risk-based margin policy available to qualifying US investors. The goal of portfolio margin is to align margin requirements with the overall risk of the portfolio. Portfolio margin usually results in significantly lower margin requirements on hedged positions than under traditional rules. While the margin requirements of Regulation T generally limit leverage on equity to 2, with portfolio margin, leverage of 6.67 or more is possible.

  ## What Is Portfolio Margin? Portfolio margin refers to the modern composite-margin policy that must be maintained in a derivatives account containing swaps (including credit default swaps), options, and futures contracts. The objective of portfolio margining is to offset the risks to the lender through consolidating, or netting positions to account for a portfolio’s overall risk. It typically results in drastically lower margin requirements for hedged positions compared to traditional policy rules. Portfolio margin accounting requires a margin position that is equal to the remaining liability that exists after all offsetting positions have been netted against each other.

• What is Portfolio Margining? - SpiderRock

  Portfolio margining is a risk-based margining methodology that uses a more sophisticated model to determine margins than Federal Reserve’s Regulation T margin, the source of the 50% margin we mentioned above. Regulation T limits the amount of credit a broker can extend to a margin account to 50% of the security’s purchase price. The trader must deposit the remainder. Margin accounts must therefore fund at least 50% of their position. However, percentage-based margins rely on a fairly crude measure. That 50% doesn’t reflect real-world risk. A trader who invests in high-risk securities has the same borrowing constraints as a trader with a hedged low-risk portfolio. [...] SpiderRock # What is Portfolio Margining? Data & Analytics What is Portfolio Margining? Portfolio margining is a margining strategy used to determine how much risk a broker can take on when lending to an investor. The margin is the collateral an investor must deposit to cover the risk of buying or borrowing financial instruments with cash borrowed from the broker. Like other margining strategies, portfolio margining is a form of risk management intended to prevent situations in which excessive lending damages brokers and destabilizes the market. [...] The TIMS portfolio margin calculations are an example of scenario analysis, a technique investors use to estimate their portfolio’s value and level of risk. Scenario analysis aims to calculate the changes in a portfolio’s value in response to different situations. Analysts often stress test portfolios by examining worst-case scenarios, providing data they can then use to ascertain and manage risk.

  # Portfolio Margin Account Trading Term Portfolio margin is a risk-based margining system used by brokerage firms to calculate the minimum margin requirement for a portfolio of securities. Unlike the traditional margin system, which sets fixed margin requirements based on individual positions, portfolio margin evaluates the overall risk of a portfolio, considering how different positions in the portfolio interact with each other. Under portfolio margin, margin requirements are typically lower for diversified portfolios, because the system recognizes that certain positions can offset potential risks. This can allow investors to take on larger positions with less capital, but it also requires more sophisticated risk management, as it reflects the actual market risks in the portfolio. [...] ### Portfolio Margin at IBKR Under SEC-approved Portfolio Margin rules and using our real-time margin system, our customers are able in certain cases to increase their leverage beyond Reg T margin requirements.

The goal of portfolio margining is to set levels of margin that more precisely reflect actual net risk of the products in the portfolio. The customer may benefit from portfolio margining in that margin requirements that are calculated based on net risk are generally lower than alternative “position” or “strategy” based methodologies for determining margin requirements. Lower margin requirements allow the customer to make more efficient use of the capital allocated to an account. The instruments included in a portfolio margining program can be limited to related instruments that are subject to the same regulatory regime (i.e., only [...] The longstanding practice for strategy-based margins is to require margin based on set formulas for a single option position or recognized strategy (e.g., a spread), regardless of what other offsetting positions are held in the account and regardless of potential market moves. Therefore, in certain cases, such as being long a put and long the underlying stock, there is no recognition of the fact that the value of one position gains when the value of a another (correlated) declines. Each position must be margined separately, unlike portfolio margining. Strategy based margin requirements are covered in Cboe Rule 10.3.

Portfolio margining first became available on a limited basis in July 2005 and was expanded in April 2007. A portfolio margin requirement is calculated by simulating market moves up and down, and accounting for offsets between and among all products held in the account that are highly correlated. For example, options on the S&P 500 Index (SPX) receive offset with options on the SPDR® S&P 500® ETF Trust (SPY) and options on the SPDR® Dow Jones® Industrial Average ETF Trust (DIA). Portfolio margin requirements are covered in Cboe Rule 10.4.
