  • Example 1: The Credit Portfolio Management Group(CPMG) proactively manages credit risk on an integrated* basis

    Dr Bob Mark

  • A significant challenge is to build a Superior ERM Solution in partnership with the C Suite whose Characteristics can be benchmarked in terms of:

    Dr Bob Mark

  • Characteristics of Policies at the Core of Superior ERM Solutions These include:The tolerance for risk (financial and non financial) is integrated and consistent with the Business Strategies (and visa versa)

    Risk measures are backtested, authorities are expressed in meaningful terms and reflect a desired tolerance for risk

    Risk is properly disclosed (e.g. Chinese walls may exist) internally and externally on a drill down and integrated portfolio management * basisDisclosureAuthoritiesRisk ToleranceBusinessStrategiesIndependentSuperior ERM Solutions

    Dr Bob Mark

  • Risk DisclosureKey characteristics of disclosure include having the ability to provide disclosures such as:Slicing and dicing the risk in real time (or near real time) by risk type, asset class ,business, product, industry, country, etcmark-to-market (mark- to-model) vs. cash flow viewsGAAP vs. Economic viewCapital (e.g. GAAP Capital vs. Economic Capital vs. Basel Capital) the main drivers of riskDisclosureAuthoritiesRisk ToleranceBusinessStrategiesIndependentSuperior ERM Solutions

    Dr Bob Mark

  • Disclosing the main drivers of financial and non financial risk would include answering such questions as :What are the top risks in the trading book and banking book (i.e. a literal hit parade of risks)Where are the concentrations of risk (e.g. hot spots)How often the list of main risks changeHave the forecasts of the top financial and operational risks (e.g. stress tests) been predictive? Have any of the top risks listed caused management to take action to alter them in any way? If so, how?What financial risks keep management up late at night?

    Dr Bob Mark

  • Example 2: August 1998:

    Equity prices dropped sharply

    Equity Volatility increased

    Liquidity dried up (Flight to quality)

    Correlations broke down

    Credit spreads widened

    Credit quality deterioratedWide Credit SpreadHigh VolatilityLow LiquidityAugust 98

    Dr Bob Mark

  • Example 3 :Certain types of backtesting disclosure have become standard (e.g. market risk).Ultimately,similar disclosure will become standard across all risk types C$ MillionsALCO Limit - Upper BoundaryALCO Limit - Lower BoundaryPotential Predicted Positive RevenueDaily Net Trading RevenuePotential Negative Revenue PredictedNov Dec Jan Feb Mar Apr May Jun Jul Aug Sep Oct August 27, 1998

    Dr Bob Mark

  • Characteristics of Methodologies at the Core of Superior ERM SolutionsThese include: VaR and Stress Test methodologies are predictive of the actual losses and integrated across all risks and all books of businessOngoing dedication toward first class risk methodology researchMathematical models are properly vetted.Positions are properly valued (and becomes a bigger deal with SOX).Risk methodologies are tied into pricing and performance measurement.IndependentFirst-ClassProactive RiskManagementPerformanceVetting &ValuationStress TestsVaR

    Dr Bob Mark

  • A term structure of risk is calculated over multiple time periodsThe term structure of PDs (from the obligor rating) and RRs (from the facility rating ) is typically applied to price as well as determine the capital for credit riskEXPOSURERECOVERIESDEFAULTS0TIMECREDIT LOSSPROBABILITYEXAMPLE

    Dr Bob Mark

  • Credit risk models (eg Mertons model) have also become deeply practical for the purposes of predicting such things as:Distribution of asset values at maturity of the debt obligationAssets ValueVTV0Probability of defaultTimeTFProbability of default (PD)

    Dr Bob Mark

  • Example 6: A key characteristic of superior credit risk stress test solutions is to arrive at reasonable paranoia stress testsStressing the boundaries of credit riskCredit risk factors may be shocked . . .. . .To produce perturbations of combined distributions of simulated future credit lossesEXPOSUREDEFAULTSRECOVERIES0TIMECREDIT LOSSPROBABILITYShocksEXAMPLE

    Dr Bob Mark

    Entergy-Koch Tradings (EKTs) advantage lies with its organizational structure. Its trading system allows it to attract and retain disciplined, quantitative, and economically driven individuals.The new capital accord would consist of thre basic pillars. Taken together they are seen as essential to the working of an effective regulatory capital framework1) A minimum capital requirement, which seeks to expand on and develop the concept of standardized rules to calculate a minimum level of capital for any institution.2) A Supervisory review of an institutions capital adequacy and internal assessment process. This will seek to ensure that the regulators are comfortable that a banks capital position is consistent with its overall risk profile and strategy. Early intervention is envisaged, if a regulator deems there to be deficiencies in either the level of capital or the internal control mechanisms.3) A Market Discipline pillar, which will act as a lever to strengthen disclosure and encourage safe and sound banking practices. Effective market discipline requires the disclosure of reliable and timely information, so that market participants and creditors can make well founded risk assessments. A significant intention, here, being to lessen the risk of Moral hazard to the local regulator. In th past regulators have often felt compelled to bail out creditors who have claimed that a lack of information and discolors prevented them from understanding the risks they were taking.

    Risk wears many disguises. One can ensure maximum transparency of risk through implementing an independent first class proactive market risk management program.

    ClickIf we put these trading risks together then an increase in equity volatility can sometimes be accompanied by a a widening in credit spreads as well as a drying up of liquidity. This does not always happen. But thats exactly what happened during the 4th quarter.In fact, some commentators have called the 4th quarter a market of firsts as we saw the dramatic coming together of these three separate risks.Specifically, Equity volatility increased which led to material losses in our Equity Derivatives book. The dramatic rise in equity volatility was accompanied by a drying up of liquidity. This flight to quality led to a widening of credit spreads which also hurt our High Yield book.

    CLICK

    The process works through sovereign and macro-economic issues, industry outlook and regulatory trends, to specific attributes (including quality of management, operating and financial positions) and eventually to issue-specific structure of the financial instrumentThe pace of innovation and the volume of activity in credit derivatives are heating up. These instruments promise to become a significant force in risk management for banks. Over the next decade they will transform credit markets. But as promising as the credit derivatives technology is, it is not yet a panacea for the credit problems of banking systems around the world. It has not yet, as is commonly believed, helped banks avoid meaningful amounts of losses in the credit cycle just ending now. Standard & Poors Rating Services estimates that, as of March 2003, $3 trillion total notional amount of credit derivatives outstanding, but only $100 billion represents a transfer of credit risk from banks lending and trading activities to other market participants. The remainder represents the dealing books of the 15 dealing banks that dominate the business, and to a much lesser extent, investment in credit risks by banks and insurance companies. In any case, the $3 trillion number pales before the aggregate loan and bond portfolios of the global banking system which total approximately $29 trillion and $5.5 trillion, respectively.Today risks that can be protected with credit derivative swaps (CDSs) are largely limited to investment grade names. This appears to have the effect of shifting the remaining risk sin the banking system further toward the riskier, non-investment grade range of the spectrum. For the market to become a significant force in moving risk away from banks, a noninvestment-grade market would have to become deeper. There is some evidence that this is occuring, at leat in the U.S. Insurance companies are reputed to be the end-providers of credit protection. They are indeed net providers of credit protection through CDSs. Most of their exposures, however, tend to be in the form of CDOs and basket trades, but these are almost exclusively of the AAA or so-called super-senior tranches of these structures, the second loss positions or, in the case of the monolines, providers of insurance wrap protection on the senor tranches. Such trances cannot be said to be intended to absorb risk.

    Losses, volume and profits are dependent random variables. This graph provides a three-dimensional illustration of the changes in expected profits, expected losses and expected portfolio size. The Efficient Frontiers illustrated in earlier slides are projections in different planes of this three-dimensional drawing.Where can trading losses related to model risk originate? Well, either from the inappropriate use of a model, e.g. using the right model with the wrong volatility parameters, i.e. what I call input risk in the graph shown on the screen, or using the wrong model. In the second case the math may be exact but the premises of the model are wrong. In the following I will illustrate both cases.Computers are now so powerful that there is a temptation to develop more and more complex models which are less and less well understood by management. There is clearly a need for risk management to have a thorough understanding of the pros and limitations of all the models being used within CIBC.Here are three examples of what can go wrong. The first two ones are directly related to model risk. The third one is more subtle and relate to both model risk and financial engineering.When it comes to infrastructure, the most important component is people. Here of course I refer to people throughout the organization, not just those in support functions.

    OR

    The last component of our integrated market risk management framework is infrastructure. The most important component of our infrastructure is people. It is self evident that a necessary condition to achieve a first class proactive management of CIBCs market risk, as illustrated by the arrow on the screen, is through hiring a highly skilled team of risk management experts.Click

    What is the way forward ...

    Our risk management plan is to build an independent and integrated business oriented process.

    We must develop a bankwide common language of risk. The language must accurately describe the multiple dimensions of risk, as well as accommodate the complexity inherent in restructuring and repackaging risk.

    As pointed out earlier, we need to develop policies and methodologies, as well as design an infrastructure which is independent but works in partnership with the risk-takers. For example, we need to appreciate the impact that our measurement of risk will have on the ability of direct risk takers to compete on price.

    Direct risk takers are responsible for understanding and pricing the risks they assume in pursuing their business activity. Our direct risk takers will only use measures of risk for pricing if they are based on best practice methodologies with low ivory tower content.
