What is a variation margin?
Like a futures broker, a clearing member may pay a variable margin to their respective clearing houses in response to unfavorable price swings in their futures contracts. This is known as the variation margin. A variation margin is used to offset the exposure resulting from holding high-risk positions. Members may choose to pay it daily or intraday. Clearing houses can maintain an appropriate level of risk that permits the orderly payment and receiving of monies for all traders using that clearing house by requiring a variation margin from their members.
Introduction to Variation Margin
Use variation margin to raise the capital in an account to the margin level. This margin and the corresponding initial and maintenance margin must be maintained by liquid assets to serve as collateral for any losses that could arise from active trading.
For instance, the initial margin on a single futures contract a trader purchases is $3,000. This is the minimum amount required to be in their account to accept the deal. There might be a $2,500 maintenance margin. This implies that the trader must top up the account to $3,000 if the balance falls below $2,500 because they have lost $500 on their position(s), which lowers the account’s buffer to an unacceptably low level. Variation margin is the amount required to raise the account to a level that will guarantee future transactions.
Imagine a broker with thousands of traders, each taking various positions and potentially winning or losing money. After taking into account these positions, the broker or clearing member must give the clearing houses money equal to the total risk associated with all of their transactions.
The precise market circumstances and price movement throughout the day determine how much variation margin is applied. A broker may determine that extra funds must be paid as a variation margin when the equity account balance exceeds the initial or maintenance margin requirement. We term this request for money a “margin call.”
Call for Margin
When a broker asks an investor to make extra contributions to reach the minimum margin requirement, it’s called a margin call. It takes effect when there is a loss on the account or when more positions are taken, bringing the equity level below what is needed to maintain those holdings. The brokerage may then liquidate the securities in the account until the required amount is paid or the risk is lowered to a manageable level if the investor cannot satisfy the margin call.
Required Maintenance Margin
When determining the variation margin, the maintenance margin is a crucial component to consider. When trading stocks, it refers to the amount of money an investor has to maintain in his margin account. Usually, it is smaller than the first margin needed to close a deal. The investor can borrow from a brokerage with these criteria. This margin serves as security against the investor’s loan amount.
A minimum of 25% is required by the Financial Industry Regulatory Authority (FINRA) for the maintenance margin on equities. Based on the investor and level of risk, other brokerages may set higher minimums, like 50%.
Maintenance margin has a distinct meaning when trading futures. It is the point at which a shareholder must credit their account with the total amount of the original margin.
Variation Margin Example
Assume that a trader pays $10 per share for 100 shares of ABC stock. The broker sets a 50% initial margin for purchases. This implies that for the broker to execute deals, he has to always have $500 in his account. Assume $300 for the maintenance margin as well.
The $300 in trading losses are subtracted from the original margin account if the price of ABC drops to $7. As a result, the starting margin account balance of $200 is now less than the $300 maintenance margin amount previously mentioned. The revised starting margin is $350, or 50% of $700. The trader must add $150 to their account to continue trading.
Conclusion
- The amount of money required to guarantee trading margin levels is called the variation margin.
- It depends on many aspects, including the nature of the asset, anticipated price changes, and market circumstances.
