Historically collateral management has been seen as secondary to the trading, risk, or financing functions. Although it has always been the case that some derivative trades required collateral to be moved, there was not typically concern over the availability of collateral as a whole – despite the collateral workflow being complex.
However, this has been changing in recent years due to increasing regulation affecting different parts of the industry, for example, clearing mandates such as those in Dodd Frank and the Uncleared Margin Rules (UMR) from BCBS/IOSCO that have mandated movement of both Variation Margin (VM) and Initial Margin (IM) on derivatives that can’t be cleared at a CCP (Central Clearing Party).
In addition, volatility across the markets has been responsible for sudden and very significant spikes in margin requirements as dynamic risk-based margin models adapt to short term market stress.
The attached charts illustrate some of the changes in IM and VM requirements over the last two years. Some highlights are:
With the UMR rules having just rolled out to phase 5 firms – and phase 6 coming into force in September 2022 – many more firms are now having to move IM on uncleared trades; adding to the demand for collateral.

Overall, this means that firms actively using derivatives now have to manage daily VM and IM movements as well as posting significant amounts of collateral against IM, and have to ensure they have sufficient supply of eligible collateral, whether that is cash or non-cash assets.
If a firm is in a position where they have insufficient assets available to meet a margin call, then they have no option but to address this with urgency. This can be via a range of tools such as freeing up cash, reassigning assets, or entering into collateral transform trades in order to meet the requirement. Handling a collateral shortfall in this way is expensive, operationally difficult and creates trading risk as it can mean a forced close out of trades causing losses on the portfolio.This is where collateral resilience comes into play.
Collateral resilience is an operational model that aims to ensure there is always sufficient collateral to meet any demand in any market.
The first stop in building resilience is knowing what you are going to be required to post out as collateral. This means having the tools in house to calculate your T+1 IM and VM exposures across all business lines and external counterparties.
Calculating your expected IM or VM requirement in advance of the daily collateral management process allows you to determine if you will have sufficient eligible collateral before you receive the margin calls from your brokers or counterparties. This also gives you the added benefit of being able to validate broker statements and margin calls.
Consistency across all business lines is key in this process, as being able to predict T+1 requirements on only some agreements gives a partial picture and doesn’t provide the ability to guarantee collateral coverage.
The next step is putting in place the ability to forecast potential future needs for collateral on short- and medium-term horizons.
VM Forecasting provides a view on the maximum amount of Variation Margin that may be called over a defined time horizon, e.g., next 5 business days, and in a certain confidence level. This is used by firms to ensure they have the right amount held in cash buffers to meet calls while freeing up excess cash for trading activities.
Forecasting of Initial Margin is also a powerful tool. For example forward projecting portfolio growth or drift over time, or defining stress scenarios of extreme market conditionsprovides a set of metrics of possible IM requirement levels which can then be analysed against inventory to determine where collateral shortfalls could occur in future.
Another extension of this concept is collateral what-if analysis, where a firm can test impact of changes to collateral eligibility haircuts or availability. This scenario is looking at situations where the overall margin requirements may not change but changes to the eligibility or rating of collateral assets means that there is no longer sufficient collateral available and a shortfall can occur.
The third leg of the Collateral Resilience solution is Optimization, and this applies to both margin and collateral.
Margin Optimization – Using techniques to optimise and reduce your margin requirement clearly improves collateral resilience because less collateral is needed. There are multiple ways to do this, starting with pre-trade checks to identify the clearing house or counterparty that has the lowest margin impact and then moving towards post trade analytics to identify trades that can be replaced or novated. . These optimization techniques allow for the same portfolio risk to be expressed while maximising portfolio offsets by counterparties. Some examples of this we see with clients are trades being novated among FCMs or futures contracts being rebooked with risk equivalent trades on a competing exchange.
The last piece of the jigsaw when ensuring collateral resilience is implementing a fully featured collateral optimization engine. Rather than the waterfall allocation models commonly used by collateral systems a true collateral optimization allows you to ensure that collateral is deployed in the most efficient way depending on each organisation’s individual constraints, and that the maximum amount of liquid assets are retained to provide buffer for any unforeseen margin calls. A complete collateral optimiser will support substitution and rebalancing and allow for configuration defining what inventory can be used and when.
The above tools require robust data across all business lines including:
|Visibility on CSA terms
|All collateral agreements, eligibility terms and constraints
|Knowing accurately what is available as collateral inventory across the organisation is essential, and this includes data on asset reference data and holding location, as well as trading constraints that may restrict ability to pledge certain assets.
|Good trade data
|Calculating the initial and variation margin in various scenarios, needs full portfolio and trade economics
This data is not always easy for firms to access – often the information is being managed by an outsource service provider, or else held in in house systems that can’t integrate to front or middle office.
So how easy is it to put these tools and processes in place? Naturally, it is not straightforward, or everyone would have done it already.
There are three areas that commonly create hurdles to implementing a true collateral resilience strategy: Systems, Data and Organisation.
The systems that need to be linked for all the above to be possible are often separate and siloed and not designed for integration and bringing back-office information into the front and middle office.
Additionally, data is represented differently between front and back-office systems with neither having the full picture so this has to be combined and harmonised. The agreement and funding data may not even be in a system or may be managed externally by an outsource service provider. All the usual issues of mismatched identifiers, and patchy trade economics come into play.
Sitting across all of this are the organisational barriers. To implement the strategies described above requires collaboration between front and back-office teams and of course, that creates challenges in aligning priorities, allocating budgets etc.
While none of the above is simple, it is well worth the investment and focus for any firm that has significant collateral exposure. Investing in systems and workflows to put in place the various tools and transparency on collateral information produces great rewards including:
