Field-in-field (FinF) technique was used with 2–4 subfields per each main field. Beams of 6 MV energy were used by default and accompanied by 15 MV beams in 3D-CRT planning to improve target coverage and avoid superficial hotspots when needed. The gantry angles were optimized by minimizing the beams-eye view (BEV) overlap with psychological marketing examples the heart and left anterior descending artery (LAD). The remaining heart and LAD volumes in BEV were shielded with multi-leaf collimator (MLC). The CTV-to-PTV margin should not be reduced below 5 mm even with daily CBCT setup. Both tVMAT and 3D-CRT techniques were robust in terms of dose coverage to the target and OARs.
This article will break down the ins and outs of this important concept and give you a better understanding of how it helps to mitigate risk and promote transparency in the derivatives market. From the variation margin formula to the initial and maintenance margin requirements, this article will give you a comprehensive overview of this critical aspect of derivatives margin trading. If the price of ABC falls to $7, then the $300 in losses in the trade are deducted from the initial margin account.
The standardization helps as it creates a contractual framework for all market participants to negotiate within. Before we proceed, it is important to note that global regulators require that parties only enter into new legal documentation once they have or are soon expected to cross the IM threshold. This means that a Fund which has material swaps exposure (i.e., AANA above the thresholds) but which does not expect to cross the 50M IM threshold with any SD group does not need to redocument all of its U-OTC trading relationships. Permissible eligible collateral types for IM, as well as the haircuts for each collateral type, are defined in the Rules.

Additionally, these requirements help to mitigate counterparty credit risk for financial firms and systemically important non-financial entities. In summary, both initial and variation margins play vital roles in the financial market to safeguard the stability of transactions involving derivative instruments. While initial margin sets the groundwork by requiring an initial deposit to be made, the variation margin then serves to maintain liquidity, as it accounts for ongoing changes in the value of open positions. Variation Margin represents funds that traders in derivatives or futures markets must add or deduct daily to cover profit or loss fluctuations. Tracked by clearinghouses, it settles differences between initial trade prices and market values, minimising default risk. In financial markets and trading, the concept of margin plays a pivotal role in determining the financial obligations and risk management strategies for investors and institutions.
Contracts for Difference (CFDs) are a type of equity derivative that allows investors to trade on the price movements of various financial instruments, such as stocks, commodities, or indices, without actually owning the underlying asset. Initial margin requirements for CFDs are typically higher than those of stock trading to account for the higher degree of leverage involved. Variation margin in CFDs is calculated by comparing the value of the open position against the underlying asset’s current market price. In the European Union, the European Market Infrastructure Regulation (EMIR) establishes requirements for over-the-counter (OTC) derivatives, central counterparties, and trade repositories. A key component of EMIR focuses on the exchange of both initial and variation margin for non-centrally cleared OTC derivatives.
If the market moves against the investor’s position, the variation margin may be required to protect against potential losses and maintain the proper margin ratio. Initial margin and variation margin are often mentioned together when discussing margin trading but they’re not the same thing. Initial margin refers to the amount of money an investor can borrow inside a margin account.
Clearing houses calculate the variation margin based on fluctuations in the value of the underlying financial instrument and notify the clearing member, who in turn, calls for the variation margin from their clients. The variation margin process serves to minimize the credit risk for both the clearing house and the other market participants by ensuring that all parties maintain sufficient margin at all times. During the life of the trade, the brokerage firm monitors the value of the securities in the margin account. If the value of the securities falls below a certain level, known as the maintenance margin, the trader will have to deposit additional funds or sell some of the securities to bring the account back into compliance. This reduces the risk of the trader defaulting on their obligation to repay the borrowed funds, protecting the brokerage firm and other market participants involved in the transaction.
For instance, the party posting cash collateral to a Custodian must direct the Custodian to invest such cash into eligible non-cash collateral. This is necessary due to potential legal issues for a secured party to take a security interest over cash (as opposed to non-cash collateral) held in a segregated collateral account. The restriction on cash also helps to reduce the risk that a loss may occur following a Custodian bankruptcy, since non-cash assets held in a segregated account are not taken onto the Custodian’s balance sheet, as cash is. Prior to the advent of UMR, SDs recognized the risk that a loss could occur in the event of a counterparty/Fund default, due to market movements between the time of the last VM movement and the closing out of the swap exposure. To account for this risk, SDs would impose an additional margin requirement on certain counterparties whom they viewed as having a high-risk profile, typically Funds. This additional margin requirement may be calculated in many ways, depending on the particular arrangement between the SD and the Fund, as well as the SD’s credit appetite.
They must ensure that their accounts are adequately funded to satisfy both types of margin requirements, thus avoiding potential margin calls and maintaining a healthy trading account. The amount of variation margin varies depending on the exact market conditions and price movement experienced over the course of the day. The variation margin payment of additional funds may be deemed necessary by a broker when the equity account balance falls below the maintenance margin or initial margin requirement. Margin trading involves borrowing capital to purchase securities, allowing traders to leverage their investments and potentially amplify profits. In this context, initial margin and variation margin are two critical components to understand.
When later recalling this collateral, the posting party must send that instruction to the Custodian, however the Custodian will not return the collateral unless a release is granted from the secured party. Again, Managers will want to automate these collateral movement instructions to the Custodian to the extent possible, in order https://g-markets.net/ to maximize the efficiency of their operations. Since IM will now be heldat an unaffiliated third party custodian (“Custodian”), it will therefore not be impacted by the bankruptcy of the SD. This therefore gives the SD the security that margin is available, but it can only access it after its Fund counterparty defaults.
Therefore, it is important for Managers to understand which jurisdiction’s Rules apply to them. The general rule of thumb is that the Rules of the domicile of the SD with which the Fund is trading will apply.[18] For instance, for a US-based Manager, with a Cayman-domiciled Fund trading with a US-based SD, the US Rules will apply. While the Rules will only apply to new transactions that are entered into after a certain date, this fact may inconveniently create multiple workflows for Managers monitoring their new and legacy transactions. Margin debt is the grease that lubricates the financial engines of the world and facilitates their smooth deployment.
At the end of each trading day, the clearinghouse, acting as an intermediary, revalues derivative contracts based on the prevailing market prices. This daily revaluation determines the profit or loss on each contract compared to its initial trade price. Initial margin and variation margin are both forms of collateral that are used in the derivatives market to reduce counterparty risk, but they serve different purposes.
Because a SD has a better credit profile than a Fund, the SD would impose this additional margin requirement on the Fund. The SD would typically not post this additional margin to their Fund counterparty in return. As this type of margin is calculated on a daily basis, it provides an immediate snapshot of the financial health of a portfolio. Should it fall, the brokerage will liquidate assets through a “margin call”, should the account holder fail to supplement the portfolio up to the new margin requirements.
Based on the shifts between setup methods, CBCT setup is recommended as a complementary method with SGRT. If the existing documents contain bespoke provisions that are inconsistent with the VM Protocol, they may wish to consider using a bilateral agreement. Institutions may also use more bespoke documentation or correspondence to help identify the appropriate margin requirements.
If the SD becomes insolvent, transactions would be closed out and, assuming that the Fund has satisfied all of its obligations to the SD, it would be permitted to take the IM back without being dragged into a long insolvency proceeding. This article provides an overview of the regulations for initial margin on uncleared OTC derivatives (“UMR” or the “Rules”) and explains to hedge fund managers and asset managers (“Managers”) how they need to prepare for these changes. Variation margin is the reserve required to maintain the ratio for an account to be viable. It is posted daily by brokers with the clearing agencies that settle the liquidity. FINRA requires this amount to be $2,000 or 100% of the purchase price of margin securities, whichever is less. Traders may make these payments on a day-to-day or intraday basis as directed by the clearing house.
The initial margin is the amount agreed by the traders while entering into the futures contract. The variation margin acts as collateral for the successful execution of the derivative contract. It helps to protect the interest of the party gaining the benefit of entering into the contract. The balance in the trading account is assessed daily after accounting for the market fluctuations.
