From 1 September 2016 until September 2022, the initial margin rules for non–cleared derivative transactions have been phased-in and an increasing number of market participants have been subject to the requirements every year.
However, many firms are still not affected by the initial margin rules for non-cleared derivative transactions, does it mean that those firms are done with initial margin concerns?
Reminder on the initial margin rules
Before the initial margin rules enforcement, exchanging “Independent Amounts” on non-cleared derivatives was not a so common practice. It was mainly a means for risk departments to mitigate the low creditworthiness of a counterparty, or the risk implied by the synthetic leverage of their clients (in the hedge funds space for example), via a one-way delivery of collateral (usually from the buy-side client to the sell-side bank), either outright or with segregation arrangements.
Now, exchanging initial margin (IM) on non-cleared derivative trades has become an established practice since the implementation of the IM rules (i.e. UMR “Uncleared Margin Rules”). Today, all firms with an Aggregate Average Notional Amount (AANA) of non-centrally cleared derivatives at consolidated group level above EUR 8 billion are subject to these rules. All OTC derivative positions (even the ones exempted from IM requirements such as physically settled forex forward and forex swap transactions) count for the purpose of calculating the AANA.
Most financial counterparties trading non-cleared derivatives are in-scope of the rules and exemptions are very limited. As of today, the rules have been transposed in many jurisdictions (e.g. EU, USA, Japan, Australia, Hong Kong, Singapore) and they embed a significant extraterritorial effect. So most cross-border transactions involving third country entities are brought in-scope of the IM obligations.
The scope of non-cleared derivative instruments subject to the rules is generally consistent across the main jurisdictions in Europe, Asia-Pacific and in the USA. Physically settled forex forwards and swaps are excluded across all jurisdictions, as well as the exchange of principal on cross-currency swaps. However, some jurisdictions may have specific exemptions, either on a permanent basis – e.g. equity options and forwards are out of scope in the USA – or on a temporary basis – e.g. equity options for which the exemption in the EU is extended for two years to January 2026 as proposed by the European Supervisory Authorities.

Initial margins can be calculated either using a table-based model, also called “Grid”, or a regulator-approved internal model, such as the Standard Initial Margin Model (SIMM) developed by the ISDA. These two methods coexist however industry participants are encouraging the adoption of a unique calculation framework to facilitate regulatory approval and minimize margin disputes between participants. They are subject to a two-ways exchange principle (each party posts and receives at the same time), a bankruptcy-remote obligation from a safekeeping perspective (implying custodial segregation) and among other things, a possible relief if margins stay under a EUR 50 million threshold.
The compliance process is complex, involves many parties and resources (e.g. trading, risk, legal, middle and back offices, IT, custodians, market platforms) and can take from 6 to 9 months on average. To face these requirements, firms have different options to comply, such as implementing the rules by their own means, or appointing a service provider, like BNP Paribas, who can propose an end-to-end solution.
Staying alert
Although the final phase has passed, vigilance must endure.
For firms already live, solid controls must be maintained to ensure the process runs properly as the volume of IM exchanges is growing.
Meanwhile some firms have not yet been impacted but could be in the future and they must monitor their Aggregate Average Notional Amount (AANA). For EU, the next AANA calculation period is between March and May 2024, for a compliance date as of 1 January 2025 with several calculation methods applying depending on the regulation. Getting close to the EUR 8 billion AANA should instantly trigger an implementation project to avoid a compliance breach.
Which initial margin calculation method?
The Grid method has the beauty of simplicity but does not consider the netting of risks inside a portfolio.
Meanwhile, SIMM is more complex to implement, maintain and implies more complex analysis when disputes arise, however it allows netting of market risks for positions executed with the same counterparty (e.g. payer vs. receiver swap), so reflects a better picture for risk-neutral portfolios.
Despite a massive adoption of SIMM, the Grid method remains an option in some relationships between banks and buy-side firms, with some agreements combining the two methodologies (SIMM and Grid) depending on instrument types.
There are multiple reasons:
- Implementing SIMM can take time for certain types of instruments, Grid can be an alternative to comply quickly with the rules.
- The regulator may prescribe to use the Grid method for specific instruments where he estimates that a specific risk is not sufficiently considered by SIMM.
- Grid can lead to lower IM amounts in particular cases and as the costs of financing posted collateral come into play, especially when collateral received cannot be reused, this is an important criterion.
For example, for a 6-month bond forward with an underlying bond maturity above 10 years, the difference between Grid and SIMM can be significant (for example, with a 40-years underlying bond maturity, the difference is about 13% of the notional). Under SIMM, a longer time-to-maturity implies higher rate sensitivities thus higher SIMM amount, whereas Grid is capped after a certain time-to-maturity.
As a result, directional rate portfolios with long maturities – typical of insurance or pension portfolios – may in some cases exhibit lower IM amounts with Grid compared to SIMM.
When the regulation does not prescribe the use of a method, a firm can opt for the different methods listed in the Credit Support Annex (CSA) signed with its counterparty.
Initial Margin threshold monitoring: buying more time
A relief mechanism has been put in place to take into consideration the complexity of implementation for firms with a low trading activity.
In April 2020, the Basel Committee on Banking Supervision (BCBS) stated:
The requirements could impose some unnecessary operational costs on smaller entities that pose no significant systemic risk to the system and would not be expected to be bound by the initial margin requirements, in particular, in light of the provided threshold amount of EUR 50 million.
BCBS, Margin requirements for non-centrally cleared derivatives
As always, the devil is in the details. This EUR 50 million threshold is the maximum threshold a firm can set with another trading relationship – both firms should consider this amount at consolidated group level. Thus, for institutions with multiple entities, themselves in trading relationships with several branches/subsidiaries of a bank, a significant part of the preparatory work (and maintenance thereafter, acknowledging developments and creation of entities) is to map and allocate the appropriate threshold amount to each relationship, function of the expected trading activity post-compliance date and the risk profile of the transactions. Finally, for a same relationship, it could also happen that these thresholds are set in an asymmetric way between the pledger and pledgee directions.
In light of that, if, for a given trading relationship, the uncleared OTC derivatives portfolio in-scope, i.e. having all its trades executed after compliance date, has its IM amounts under the threshold (EUR 50 million or lower depending on the allocation mechanism described previously), it is then exempt of IM postings until it reaches this threshold. Firms under the threshold are not expected to have the specific documentation in place, custodial or operational processes related to IM.
This, however, is only supposed to grant more time for firms and custodians to prepare for full IM compliance, as once this threshold is exceeded, firms are expected to start posting and collecting, thus have every required documentation and processes in place and running. Therefore, a precise monitoring of the thresholds is crucial.
Latest evolutions of the IM model
Since its introduction, most industry participants have adopted the SIMM model. However, there remain areas for strengthening initial margin models. Regulators, such as the Prudential Regulation Authority (PRA), highlighted some concerns about the proper implementation and use of the SIMM model, and thus the ability to identify and correct model malfunctions in a stressed market.
In 2023, significant changes were published with the revision of the Governance Framework beginning of March, including the modification of the recalibration frequency from annual to bi-annual to adjust the SIMM model shortfalls more dynamically.
On top of that, the ISDA SIMM Remediation defined a EUR 25 million threshold above which back testing and reporting must be in place, regardless of whether the portfolio exposure is above or below the EUR 50 million margin exchange threshold. Thus, even if they do not exchange margin, certain entities will be for the first time subject to the back testing obligation and will have to monitor where they stand against this EUR 25 million threshold.
On 3 July 2023, the European Banking Authority published the final draft of the Regulatory Technical Standard on the Initial Margin Model Validation to answer to the risk mitigation for non-cleared OTC derivatives in accordance with the Article 11(15) of the European Market Infrastructure Regulation (EMIR 648/2012). It defines obligations for market participants, around their internal compliance policies on the Initial Margin framework (governance and back testing methodology) and harmonises the supervisory review for validation of the internal model.
Those requirements of Initial Margin validation will be phased-in and will apply to the largest firms first, as per the AANA calculation criteria.
In a first phase (date not yet published at the time of writing), the firms above EUR 750 billion gross notional of uncleared OTC derivatives will follow the “standard” approach as defined in the Regulatory Technical Standard (RTS), which adds-up several procedure and documentation requirements compared to the current framework of internal model approval.
To simplify the validation for firms below EUR 750 billion, these will be subject to the “simplified” approach, two years after the first phase.
However, in parallel to the final draft of the RTS, the European Banking Authority (EBA) published an opinion letter in which they recommend facilitating the coordination with the industry by centralising the validation exercise. The EBA also proposes to review the scope of firms impacted by the RTS requirements, by restricting the submission only to the largest one.
The rules may still evolve over time. As we observe reviews for other major regulations, some consultations have happened recently in Europe, the latest one being issued by the Basel Committee on Banking Supervision and the International Organization of Securities Commissions about the Initial Margin model validation framework.
