Operational Risk Modeling in Financial Services: The Exposure, Occurrence, Impact Method (Wiley Finance) 1st Edition
Purchase options and add-ons
Transform your approach to oprisk modelling with a proven, non-statistical methodology
Operational Risk Modeling in Financial Services provides risk professionals with a forward-looking approach to risk modelling, based on structured management judgement over obsolete statistical methods. Proven over a decade's use in significant banks and financial services firms in Europe and the US, the Exposure, Occurrence, Impact (XOI) method of operational risk modelling played an instrumental role in reshaping their oprisk modelling approaches; in this book, the expert team that developed this methodology offers practical, in-depth guidance on XOI use and applications for a variety of major risks.
The Basel Committee has dismissed statistical approaches to risk modelling, leaving regulators and practitioners searching for the next generation of oprisk quantification. The XOI method is ideally suited to fulfil this need, as a calculated, coordinated, consistent approach designed to bridge the gap between risk quantification and risk management. This book details the XOI framework and provides essential guidance for practitioners looking to change the oprisk modelling paradigm.
- Survey the range of current practices in operational risk analysis and modelling
- Track recent regulatory trends including capital modelling, stress testing and more
- Understand the XOI oprisk modelling method, and transition away from statistical approaches
- Apply XOI to major operational risks, such as disasters, fraud, conduct, legal and cyber risk
The financial services industry is in dire need of a new standard -- a proven, transformational approach to operational risk that eliminates or mitigates the common issues with traditional approaches. Operational Risk Modeling in Financial Services provides practical, real-world guidance toward a more reliable methodology, shifting the conversation toward the future with a new kind of oprisk modelling.

Editorial Reviews
From the Inside Flap
Whilst regulators are proposing to withdraw the capacity for financial institutions to assess capital using internal statistical models, Operational Risk Modeling in Financial Services offers a well-tested, new approach.
Drawing on the authors' years of experience and lessons learned, Operational Risk Modeling in Financial Services outlines a fresh approach for the analysis and modeling of operational risks within financial institutions. The book discusses the need to measure operational risk to meet regulatory requirements, such as capital charge calculation or stress tests, as well as non-regulatory requirements including risk appetite and risk management.
The authors explain the challenges measurement presents and explore the three main tools used in operational risk analysis and modeling: RCSA, loss data models and scenario analyses. The book then details the authors' XOI method, for Exposure, Occurrence and Impact. This method makes it possible to define the exposed resource for each of the operational risks, therefore making it possible to describe the mechanism that can generate losses. Once the mechanism is identified, it can be successfully modeled and quantified.
From the Back Cover
Praise for Operational Risk Modeling in Financial Services
"Patrick Naim and Laurent Condamin articulate the most comprehensive quantitative and analytical framework that I have encountered for the identification, assessment and management of Operational Risk. I have employed it for five years and found it both usable and effective. I recommend this book as essential reading for senior risk managers."
-C.S. Venkatakrishnan, CRO, Barclays
"I had the pleasure to work with Laurent and Patrick to implement the XOI approach across a large multinational insurer. The key benefits of the method are to provide an approach to understand, manage and quantify risks and, at the same time, to provide a robust framework for capital modeling. Thanks to this method, we have been able to demonstrate the business benefits of operational risk management. XOI is also well designed to support the Operational Resilience agenda in financial services, which is the new frontier for Op Risk Management."
-Michael Sicsic, Head of Supervision, Financial Conduct Authority; Ex-Global Operational Risk Director, Aviva Plc
"The approach described in this book was a 'Eureka!' moment in my journey on operational risk. Coming from a market risk background, I had the impression that beyond the definition of operational risk, it was difficult to find a book that described a coherent framework for measuring and managing operational risk. Operational Risk Modeling in Financial Services is now filling this gap."
-Olivier Vigneron, CRO EMEA, JPMorgan Chase & Co
"The XOI methodology provides a structured approach for the modeling of operational risk scenarios. The XOI methodology is robust, forward looking and easy to understand. This book will help you understand the XOI methodology by giving you practical guidance to show how risk managers, risk modellers and scenario owners can work together to model a range of operational risk scenarios using a consistent approach."
-Michael Furnish, Head of Model Governance and Operational Risk, Aviva Plc
"The XOI approach is a simple framework that allows to measure operational risk by identifying and quantifying the main loss drivers per risk. This facilitates the business and management engagement as the various drivers are defined in business terms and not in risk management jargon. Further, the XOI approach can be used for risk appetite setting and monitoring. I strongly believe that the XOI approach has the potential to become an industry standard for banks and regulators."
-Emile Dunand, ORM Scenarios & Stress Testing, Credit Suisse

A "must read" for all risk practitioners in the operational risk modeling.
This approach has not been taught to me in my risk management courses, yet it allows one to approach risk quantification in a rational and structured way.
On the way to explaining XOI (Exposure, Occurence, Impact) method, they pass on to you understandable, boiled-down to core, concepts of math (Bayesian networks, probability distributions, convolutions of laws ... ). And you effortlessly pick it all up, so that in the end, you wonder how risk models could be worked out otherwise. As the core of the method stays true to the nature of risk and uncertainties, the method is applicable in a wide array of fields from cyber attacks to road safety, portfolio hedge to credit default, macro economics to bank finance, guaranteeing an unbiaised and explicit quantification of uncertainties.
In this way, risks or threat-laden situations can be dealt with efficiency in circumstances where you had once to rely on the hunch or intuition of "experts". These experts now serve even more usefully as their inputs, and not their "in petto" opaque estimations, are explicited. Their scenarios have been "math-ified".
It is also remarkable that the authors so generously share their know-how in modelling difficult situations by dispensing practical and life-tested advice on implementing variables and indicators. Risk consultants might as well take benefit from this.
In short, this is an Operational book on risk models, as much as a book on modelling Operational Risks.

In short, this is an Operational book on risk models, as much as a book on modelling Operational Risks.
It focuses on capturing the forward-looking view of the risk, and understanding what factors drive the risk. The approach is new and refreshing because it avoids the "reflex reaction" to use historical loss data (how much was lost) as the primary input into the quantification process. Rather, it first decomposes the risk into the risk factors that influence the level of risk, and then looks to calibrate those factors using the best available information. If the factor in question is observable, then data can be used to calibrate, otherwise Subject Matter estimates can be used.
The XOI method for quantifying operational risk is a very flexible and adaptable framework.
With the Loss Distribution Approach (LDA) falling out of favor as the preferred method for quantifying Operational Risk, Scenario Analysis has been gaining popularity. This book and the XOI framework proposes a road-map for financial institution to perform and conduct Scenario Analysis in a more structured manner.
Ultimately, this approach helps highlight the risk factors that are most material, and create a relatively more objective and repeatable mechanism to measure the risks.
