What is Remargining (Derivatives)?
Remargining is a critical risk management process in the derivatives market that involves requiring a party to a futures or options contract to deposit additional funds to cover potential losses that exceed the initial margin. This process is essential for maintaining the financial integrity of trading and protecting counterparties from significant financial exposure. It highlights the dynamic nature of margin requirements, which fluctuate with market volatility and contract performance.
In essence, remargining serves as a safeguard against default. When the value of a derivative position moves unfavorably, potentially leading to a substantial loss for one party, the broker or clearinghouse steps in to demand more collateral. This ensures that the party holding the losing position has sufficient funds to cover the unrealized losses, thereby preventing a cascade of defaults that could destabilize the entire market.
The process is triggered when a trader’s account equity falls below a predetermined maintenance margin level. This maintenance margin is set by the exchange or clearinghouse and represents the minimum equity required to keep a position open. Failure to meet a margin call, which is the formal request for additional funds, can lead to the liquidation of the trader’s positions to cover the deficit.
Definition
Remargining (Derivatives) is the process by which a clearinghouse or broker demands additional collateral from a trader to cover unrealized losses on a derivative position that has moved against the trader’s favor, ensuring the account equity remains above the maintenance margin level.
Key Takeaways
- Remargining is a mechanism to address adverse price movements in derivative contracts by demanding additional funds.
- It is triggered when a trader’s account equity falls below the maintenance margin level.
- Failure to meet a margin call can result in the liquidation of open positions.
- Remargining protects clearinghouses and brokers from counterparty default risk.
- It is a dynamic process that fluctuates with market volatility.
Understanding Remargining (Derivatives)
When a trader opens a position in futures or options, they are required to deposit an initial margin, which is a good-faith deposit. This initial margin is a percentage of the contract’s total value, designed to cover potential, but not extreme, losses. However, markets are volatile, and the value of a derivative contract can change rapidly. If the market moves against the trader’s position, the equity in their account decreases. If this equity dips below the maintenance margin, a margin call is issued.
The margin call is the formal demand for the trader to deposit funds to bring their account equity back up to the initial margin level. The amount of the margin call is calculated to cover the deficit and restore the account to a healthy equity level. This process is performed at least daily, often intra-day, by clearinghouses and brokers to continuously monitor and manage risk exposure across all participants.
The daily settlement process, also known as marking-to-market, plays a crucial role in remargining. At the end of each trading day, all open positions are valued at their current market price. Profits are credited to traders’ accounts, and losses are debited. If the debiting of losses causes the account equity to fall below the maintenance margin, a margin call for remargining is triggered.
Formula (If Applicable)
While there isn’t a single universal formula for remargining itself, the calculation of a margin call is based on the difference between the current account equity and the maintenance margin. The basic concept involves bringing the account back to a specified level.
Margin Call Amount = (Required Equity Level – Current Account Equity)
Where the Required Equity Level is typically the initial margin or a level specified by the broker/exchange, and Current Account Equity is the value of the account after accounting for unrealized gains and losses from marking-to-market.
Real-World Example
Suppose a trader buys 10 contracts of crude oil futures with an initial margin requirement of $5,000 per contract, totaling $50,000. The maintenance margin is set at $4,000 per contract, or $40,000 total. If the price of crude oil drops significantly, causing the trader’s position to lose $15,000 in value by the end of the day, their account equity falls to $35,000 ($50,000 initial margin – $15,000 loss).
Since $35,000 is below the $40,000 maintenance margin, a margin call is issued. The trader must deposit an additional $15,000 to bring their equity back up to the initial $50,000 level ($40,000 maintenance margin + $10,000 to restore to initial margin level), or at least cover the difference to meet the maintenance requirement as per exchange rules. If the trader fails to deposit the funds, their position would be liquidated by the broker.
Importance in Business or Economics
Remargining is fundamental to the stability and functioning of derivatives markets. It ensures that participants can meet their obligations, thereby reducing systemic risk. Without effective remargining, large price swings could lead to widespread defaults, paralyzing trading activities and potentially triggering broader financial crises.
For businesses that use derivatives for hedging, understanding margin requirements and the potential for remargining is crucial for financial planning and risk management. It helps in accurately assessing the cost of hedging strategies and ensuring sufficient liquidity is available to meet margin calls, even during periods of extreme market stress.
The process also promotes market discipline by discouraging excessive speculation. Traders who cannot manage their risk or maintain adequate capital are prevented from accumulating positions that could pose a threat to market stability. This contributes to a more robust and reliable marketplace for all participants.
Types or Variations
While the core concept of remargining remains consistent, variations can exist based on the specific derivatives product, the exchange, and the clearinghouse’s rules. These can include different initial and maintenance margin requirements, different frequencies for marking-to-market and margin calls (e.g., daily vs. intra-day), and specific rules for different asset classes like equities, currencies, commodities, or interest rates.
Some sophisticated trading strategies might involve portfolio margining, where margin requirements are calculated on the net risk of an entire portfolio rather than individual positions. This can lead to lower overall margin requirements for well-diversified portfolios. However, the underlying principle of remargining to cover adverse movements and maintain adequate collateral still applies.

Frequently Asked Questions (FAQs)
What is the difference between initial margin and maintenance margin?
The initial margin is the amount required to open a derivative position, serving as a good-faith deposit. The maintenance margin is the minimum equity level an account must maintain after the position is established; if equity falls below this, a margin call is triggered for remargining.
How often are margin calls for remargining typically issued?
Margin calls are typically issued at least once a day as part of the daily settlement process (marking-to-market). However, depending on market volatility and the broker’s or exchange’s rules, intra-day margin calls can also be issued if significant adverse price movements occur during the trading day.
What happens if a trader cannot meet a margin call for remargining?
If a trader fails to deposit the required funds to meet a margin call, their broker or clearinghouse has the right to liquidate the trader’s open positions. This liquidation is done to cover the losses and bring the account equity back to an acceptable level, thereby mitigating further risk to the broker and the market.
