Podcast with AcadiaSoft – “Crunch time: Why data standardization in OTC Derivatives matters”

The standardization of the way the Over-The-Counter bi-lateral derivatives industry records and digitizes trade details is hugely important. But the process of achieving those methods of standardization is anything but simple. The brand new episode of our ‘Ahead of the Curve’ #podcast series sees our panel of experts discuss why data standardization in OTC Derivatives is so vital and how the industry can look to prepare.

To get under the skin of this highly topical issue, Fred Dassori and Richard Barton from AcadiaSoft are joined by Donal Gallagher, Chief Executive at Quaternion Risk Management, who shares his outlook for standardization: “The industry is ready for standardization, but in practise I think firms need to allow more time. I think they need to start earlier on this journey of preparedness to allow more time for testing, to allow more time for processes to bed in and to understand what standardization needs to be put in place”.

A Time of Stress: SIMM Passed the Test – ISDA SIMM™ Data Study

In February 2020, the COVID-19 pandemic began to sweep across the world, sparking a global shutdown and ushering in the beginning of a steep recession and potentially ushering in an indeterminate period of global economic uncertainty. Selloffs in the Equity, Bond, and Commodity markets began to produce losses ranging from 35% to 40% from their all-time highs, leading to volatility levels not seen since the recession in 2008. The OTC derivatives market had its share of volatility as well, seeing high yield CDS indices reaching new highs in March. As the volatility picked up, so did collateral swings and movements across all markets, including the OTC derivative market, prompting Central Counterparties (CCPs) to adjust their margin models mid-stream to account for collateral shortfalls. The impact of the COVID shutdown also prompted regulators across the globe to delay the margin rules for bilateral OTC derivatives by one year.The Recent Volatility and ISDA SIMM™

As market volatility increased, risk models in the cleared OTC markets adjusted rapidly to ensure firms were adequately covering risk, but on the bilateral OTC side, firms exchanging margin using the ISDA SIMM model (SIMM) had experienced something entirely different. SIMM is the initial margin model used by all firms that are in scope for the non-cleared margin rules to exchange regulatory initial margin. SIMM is by design a model that is intended to avoid procyclicality. It was conservatively built to ensure it could withstand market shocks to allow firms who use the model to cover their risk without making adhoc adjustments, even through a highly volatile market period of stress. During the initial volatility period of February through March 2020 many industry experts questioned whether SIMM was built to be able to withstand these shocks. By all intents and purposes, SIMM did withstand the period of stress and volatility based on the data and evidence that we will demonstrate in this study.In addition, SIMM does have a robust governance structure in place to ensure that if there are observations of exceedances produced by the model due to new periods of stress, they are identified and the model is altered accordingly to ensure risk is being appropriately captured and that the model remains conservative enough to avoid future events of procyclicality.

In this data study we explore exactly how SIMM performed during the period of January through mid-April 2020. We will look to see what, if any, exceedances took place across asset classes and compile benchmark data to illustrate how SIMM performed against Value-at-Risk (VAR) models during other periods of stress. We will also look to make recommendations based on the data observed to any changes we believe could benefit the model.

Acadia QRM SIMM Data Study 2020

Simm may come with a side benefit – a common data standard

Quaternion’s ORE XML trade format standard is being widely adopted by the industry through client subscriptions to our partnership with AcadiaSoft for risk-related initial margin (SIMM) compliance solutions, along with steady open source adoption. While the AcadiaSoft Services have certainly experienced certain mild growing pains referenced in the article, industry-wide adoption of ORE XML will lead to greater standardization in the OTC derivatives market, and potentially bring with it even greater synergies and cost reductions as we look to offer more value-added risk services to the industry.

AcadiaSoft and Quaternion Form Risk Services Partnership

Norwell, MA, and Dublin, Ireland August [2], 2018 – AcadiaSoft Inc., the leading industry provider of margin automation solutions worldwide, and Quaternion Risk Management Ltd., a leading risk analytics firm, today announced the formation of a partnership to provide risk services for firms subject to initial margining requirements for non-centrally-cleared derivatives. The initiative couples AcadiaSoft’s proven capabilities in automation with Quaternion’s extensive quantitative expertise and will enable AcadiaSoft clients to access a range of services via the secure environment of the AcadiaSoft Hub.

“Combining AcadiaSoft’s existing infrastructure with our risk analytics tools presents opportunities to create new products that will greatly benefit both the smaller players in the non-centrally-cleared market facing near-term hurdles, as well as larger, established institutions looking to reduce spend on functions that have become ‘business-as-usual’ and could now be more efficiently outsourced and standardized,” said Donal Gallagher, chief executive officer at Quaternion.

Initially, the partnership will focus on helping firms with non-centrally cleared derivatives portfolios meet the operational and regulatory challenges associated with margin requirements. On September 1, 2016, the largest banks that trade non-centrally cleared derivatives were required to post and collect initial margin (IM) due to a new margin framework established by the Basel Committee on Banking Supervision (BCBS) and the International Organization of Securities Commissions (IOSCO), and each year since, and through 2020, those requirements touch a growing set of sell-side and buy-side firms.

“We expect to be able to significantly cut the burden placed on market participants by the non-cleared margin rules and make achieving compliance a straightforward process – even for relatively small firms,” said Fred Dassori, head of Risk Services and corporate development at AcadiaSoft. “After collaborating with the team at Quaternion on a range of projects over the past year, we’re excited to now be formalizing our partnership, and we’re looking forward to working together to greatly expand the set of tools we offer and give our clients a simple and efficient path forward.”

By offering these future services through the same platform as AcadiaSoft’s existing Initial Margin Exposure Manager and MarginManager products, which sit at the heart of the current IM calculation, reconciliation, and collateral messaging processes, AcadiaSoft and Quaternion aim to make their new risk services as seamlessly-integrated into existing industry workflows as possible.

Big Data and Graph Theoretic Models: Simulating the Impact of Collateralization on a Financial System

In this paper we represent a financial system using a weighted directed graph model. We simulate and analyze the impact of financial regulations regarding the collateralization of derivative trades on systemic risk, employing a novel open source risk engine. The analysis finds that introducing collateralization does reduce the costs of resolving a financial system in crisis. It does not, however, change the distribution of risk in the system. The implications of the analysis highlight the importance of scenario based testing using hands on metrics to quantify the notion of system risk.

Forecasting Initial Margin Requirements – A Model Evaluation

The introduction of mandatory margining for non-cleared portfolios has major implications for the pricing and risk measurement of OTC derivatives. In particular, a model for estimating future initial margin requirements is necessary to enable the calculation of pricing adjustments (MVA), net counterparty credit exposures and credit capital (RWA). Existing literature on the topic suggests a model which makes use of regression techniques, but little detail is available on the predictive quality of these models within a Monte Carlo simulation framework. We review these regression-based initial margin models in detail and compare their output against the actual margin requirements measured by the ISDA SIMM methodology. We observe that the models generally perform well for single trades but show some degradation for single option products and larger diversified portfolios. We investigate potential extensions and improvements to the model, along with examining some additional “conservatism” features that may have application in the context of credit exposure measurement. The Initial Margin modelling approaches discussed here are similarly applicable to centrally cleared or exchange-traded portfolios.

Daisy Chains and Non-cleared OTC Derivatives

By Donal Gallagher, Roland Lichters, Sharyn O’Halloran, and Roland Stamm

The non-cleared over-the-counter (OTC) derivative market is estimated at $493 trillion notional [1]. One of the central triggers of the 2008 Financial Crisis was financial institutions’ excessive exposure to counterparty risk. These exposures peaked at over $4.5 trillion in 2008 [1]. The response of the global regulatory community to the financial crisis has been to introduce regulations and standards aimed at reducing the amount of counterparty credit risk in the financial system. These initiatives gave rise, for example, to the introduction of mandatory clearing for certain common classes of derivatives (cleared derivatives) and more recently the introduction of similar standards for non-cleared derivatives [2]. The primary means promoted to mitigate risk are mandatory variation margin (collateral against today’s value) and mandatory initial margin (collateral against the change in valuation in the event of default). The total amount of initial margin introduced as a result of these changes is estimated at $315 billion for US banks alone [3]. The regulatory expectation is that most derivatives classes will ultimately be subjected to mandatory clearing; however, the current volume and the slow rate of convergence toward mandatory clearing suggest that large volumes of derivative contracts will continue to be subject to the non-cleared OTC regime for the foreseeable future.

SPS Spotlight – FinTech and Financial Regulation

Streamed live on 15 Nov 2016

Columbia University School of Professional Studies presents
A Panel Discussion with Professor Sharyn O’Halloran, Thomas Deely, and Guests

A key issue for regulators and the financial service industry is mitigating systemic large-scale counterparty risk. Currently, individual financial institutions and regulators conduct systemic risk exposure analysis using proprietary models and data protocols absent any agreed upon baseline, best practices or public scrutiny. Without industry standards, shared benchmarks, or means to validate results, the impact of alternative policy interventions on the overall risk in the financial system remains uncertain.

This initiative showcases new open source analytical tools that develop highly granular trade and cross-asset class risk simulation and aggregate at the counterparty level. Bringing large-scale open source risk models to the public domain will enable a standard-based approach that facilitates research and greater understanding of the impact that policy levers have on the financial system.
