International Swaps and Derivatives Association highlights Open-Source as future of technology infrastructure.
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 . 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 . 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 . 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 . 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.
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.

The tenor basis phenomenon became significant with the 2007 financial crisis and has altered the traditional way of one-curve pricing and risk management to a multi-curve phenomenon. The stochastic nature of basis spreads between curves particularly poses a challenge for forward looking applications like XVA or real world measure exposure analytics. This paper presents a Two- factor Gaussian approach for modelling multiple fixing curves and basis spreads in the risk neutral and spot measure, shows the impact on basis swap exposure, investigates the correlation structure and discusses the pros and cons of interpreting as a spread or multi curve model respectively.
Quaternion Risk Management announces the launch of opensourcerisk.org – the first end-to-end open source risk application. opensourcerisk.org will provide complex risk analytics for financial institutions through a series of releases.
Continue to follow our journey as, today, we launch our contribution to the development of next generation global risk standards. We welcome your contribution to our opensourcerisk.org framework as its evolves.
Quaternion recently sponsored a September 14th Risk.net webinar discussion on the evolution of XVAs. Participants included Scott Sobolewski (Principal Consultant at Quaternion), Yann Coatanlem (MD, Head of Multi-Asset Quantitative Analysis at Citigroup,
Massimo Morini (Head of Interest Rate and Credit Models, Banca IMI), and Peter Zeitsch (Solution Architect at Calypso Technology).
The list of valuation adjustments banks must apply when pricing a derivative has grown exponentially and given rise to an alphabet soup of new valuation adjustments. The term XVAs has been coined to describe the entire family, namely funding valuation adjustment (FVA), capital valuation adjustment (KVA), and now, margin valuation adjustment (MVA). The sheer volume of these adjustments coupled with the impact on profitability has led banks to compute the capital required to support them through the life of the trade. This has considerably increased the computational complexity as well as placed demands for real time calculation of all of this information. Needless to say, dealers attempting to manage their XVAs are finding the process extremely challenging and a few have joined-up in an effort to curb their XVAs, under the banner of optimisation and trade compression.
Discussion topics included:
- What is MVA and how does it interact with the other XVAs?
- How complex is MVA, relative to other adjustments?
- In practical terms, where is the industry on MVA at this point?
- Do you expect MVA to follow the same evolutionary path that we’ve seen for other XVAs?
- Interaction between MVA, KVA, CVA, DVA, FVA
- Rank order of the different XVAs, once IM regime has been fully implemented
- What are the key regulations that will determine the correct MVA/XVA treatment for a trade?
- What are the practical / implementation challenges?
- Given all of this, what timeline is likely for MVA to start showing up in pricing?
- How much pricing dispersion is it likely to produce?
- Can MVA already be seen for cleared trades with CCPs?
- Accounting treatment for MVA (IFRS 9, 13)
- What does the blending / blurring of XVAs mean for the way they are managed? What is the right organisational structure?

Scott Sobolewski, a Principal Consultant in our Boston office, recently published an article in Treasury & Risk Magazine titled “How Do Dealer Banks Price Derivative Products?”. The article helps corporate treasurers, asset managers, and other end-users of over-the-counter (OTC) derivatives understand the various components of bank regulatory and capital charges currently built into dealer pricing. Most users have grown comfortable with concepts like CVA and FVA, though newer valuation adjustments for initial margin (MVA) and regulatory capital (KVA), as well as Basel’s new initial margin rule taking effect on September 1, 2016, make it more important than ever to keep pace with new regulation. The market environment necessitates that risk managers at large financial institutions and end-user treasury functions understand how bank pricing has evolved in the wake of Dodd Frank and Basel III, not only for regulatory compliance exercises like reporting or stress testing, but for proactive risk management. By facilitating increased understanding on both sides of a derivatives trade, Quaternion hopes to increase liquidity within the shrinking uncleared OTC derivative market and reduce overall systemic risk across the financial system.
Quaternion sponsored a QuantLib User Meeting at the Chartered Accountants’ Hall, One Moorgate Place, London EC2R 6EA on Tuesday 12th July 2016.
“The QuantLib project is aimed at providing a comprehensive software framework for quantitative finance.

A top-class panel of risk experts from banks, universities and audit companies discussed the current state and the future of standard approaches, risk factor models, simulation and regulation on May 3rd 2016 in Frankfurt.
While a South Korean delegation was getting into the mood for the annual meeting of the Asian Development Bank at the Grandhotel Hessischer Hof, many risk managers from banks and other companies arrived in the room next door. The setting was perfect for the eclectic mix of experts, who maintained an interesting discussion for more than an hour. Roland Stamm, Partner at Quaternion Risk Management, was responsible for the organization of the evening and moderated the panel. The discussion was very dynamic and marked by both unanimously agreed and opposed analyses of various aspects of the status quo in risk modeling.

Modern Derivatives Pricing and Credit Exposure Analysis: Theory and Practice of CSA and XVA Pricing, Exposure Simulation and Backtesting
The past 10 years have see an incredible change in pricing financial products, driven by the credit crisis which started in 2007 with the near bankruptcy of Bear Sterns, reaching a first climax with the implosion of the US housing market and the banking world’s downfall, and then turning into a sovereign debt crisis in Europe. A major change to have affected the landscape has been the increasing complexity in the valuation of derivatives – multi-curve pricing , various value adjustments (XVAs) using Monte Carlo simulation of markets through time , credit risk measurement and capital allocation – all based on increasingly complex mathematical and IT machinery.
Published in November 2015, Modern Derivatives Pricing and Credit Exposure Analysis is a comprehensive, practical guidebook for modern derivatives pricing and credit analysis, written with the practitioner in mind. Theoretically rigorous but focused on market practice, it provides a detailed and consistent toolkit of pricing and risk methods to cope with the increasing complexities of today’s derivatives management. The presented risk factor evolution models for six different asset classes allow efficient computation of various value adjustments (XVAs) and risk measures in a competitive and increasingly regulated environment. The text bridges the gap between the risk-neuraland real-world measure for backtesting purposes and explains different methods for speeding up XVA computation in order to allow fast calculations of margin adjustment or XVA greeks.
Written to provide sound theoretical detail with practical implementation, this book provides readers with both an overview and deep dive into valuation and risk methods applied in the industry today.
