A maintenance margin call is issued when the equity in your Individual/Joint Brokerage Account or Trust Account that your Margin Loan is from falls below the maintenance margin requirements. There are primarily two scenarios that could cause this:
- Market depreciation: If the equity in your account drops below the minimum maintenance requirement set by your brokerage, it could trigger a maintenance margin call. Market depreciation is usually the most common cause for lower equity, but any fees or interest charges could also reduce your account equity.
- Higher Margin Requirements: The maintenance margin requirements for your portfolio could also increase due to the following:
- Rebalancing: If securities with higher margin requirements are underweight in your portfolio, relative to securities with lower requirements, rebalancing an account with a Margin Loan could trigger a margin call. This most commonly happens when you modify your portfolio to contain higher requirement securities.
- Margin Requirement Changes: Your brokerage or clearing firm can increase the margin requirements on specific securities based on volatility and other factors.
Let’s look at these scenarios using an example:
Say your account value is $50,000, which consists of $49,000 invested in securities and a $1,000 cash balance. Then with the standard 25% maintenance margin requirement rate you borrow $10,000 using an M1 Margin Loan.
In the above example, the account has $40,000 of equity compared to the maintenance requirement of $12,500 resulting in $27,750 of excess equity.
Scenario 1: Market Depreciation
When you know the maintenance margin requirement rate of a portfolio (in this case 25%), the following formula will tell you exactly how much the portfolio value would have to depreciate to trigger a margin call:
(Margin Loan balance-cash balance) / (1 – maintenance margin requirement rate)
In our example, that translates to:
($10,000-$1,000) / (1 - 0.25) = $13,333.34
This means that the $49,000 portfolio value would have to drop below $12,000 to trigger a maintenance margin call (which is over a 70% drop!).
Let’s look at the numbers right before the maintenance margin call when the portfolio value drops to $13,000, and the cash balance stays uninvested at $1,000.
We see that maintenance excess equity remains positive; therefore, no maintenance margin call is issued.
When the portfolio value drops to $11,000 (below the previously calculated $12,000 threshold), we see that the maintenance excess equity is negative and a margin call for $750 would be issued.
In the above example, you would need to deposit cash or sell securities to meet the margin call.
Scenario 2: Higher Margin Requirements
Now let’s review an example where the portfolio value does not change, but you update your portfolio to include highly volatile stocks with a 100% maintenance margin requirement rate and rebalance.
In this case the maintenance requirement increases from $12,500 in the first scenario to $50,000, causing the maintenance excess equity to drop and resulting in a $10,000 maintenance margin call.
