CRITICAL SUCCESS FACTORS IN IMA IMPLEMENTATION

Risk Intelligence: The 21st Century Frontier of Market Efficiency
THE ROAD TO SYSTEMATIC RISKS
Number of crisis over time appears to be rising
370 years of cyclical crises always resulted from decoupling the perception of current risk versus future value
REGULATIONS AIM AT DE-RISKING VITAL ACTIVITIES
CAPITAL
Credit Risk Weighted Assets + [12.5 x (Mkt Cap Charge + Ops Cap Charge)]CAPITAL
Credit Risk Weighted Assets + [12.5 x (Mkt Cap Charge + Ops Cap Charge)]
Systematic risks through countercyclical prudential supervisory measures.
BCBS 164 on strengthening resilience contains proposals for capital buffers to contain leverage and exposure
Idiosyncratic risk stabilised through adjusted through risk adjusted capital reserves
IDIOSYNCRATIC RISK MANAGEMENT IS TO BALANCE THE CREATION OF VALUE WITH EXPOSURE TO RISK FACTORS

Risk is a measure of sensitivity to factors of exposure under scenarios
Managing risk is to align the firm’s exposure to the risk factors with its appetite for it

CREATE A CULTURE OF RISK MANAGEMENT – KEEP IT ALIVE
Risk Intelligence
No financial instrument is inherently risky
Valuation and aggregation methodology (covariance) depend on the nature of tail events
Crashes follow booms, but the future is not like the past
Restore the balance Capital Efficiency / Risk to alignCorporate Governance and Risk Appetite
Support Regulatory Compliance with information onmarket behaviour in addition to statistical analysis

CREATING A RISK INTELLIGENT GOVERNANCE AND COMPLIANCE FRAMEWORK
• Enterprise-wide aggregation (by risk factor)• Sensitivity analysis (portfolio and entity level)• Stress testing
• Effective counterparty exposure • Expected Positive Exposure (EPEs)• Credit Value Adjustments (CVAs)
GOVERNANCE DRIVEN
• Liquidity Risk Management• Stress test ALM & gap analyses• Counterparty driven gap analyses
• Collateral liquidity• Valuations of OBS exposure
CREATING RISK INTELLIGENCE
• Limit & Collateral Management• Net counterparty exposure• Risk concentration and sensitivity limits• Leverage ratios and OBS
COMPLIANCE DRIVEN
THE FALLACY OF MODERN FINANCE THEORYModern finance theory leads to
• Measuring expected return as a function of volatility (CAPM)• Diversifying risks through expectations of low covariance• Expressing tail event probabilities as a frequency of occurrence
The act of (collectively) observing an area of financial safety makes it risky
A. Persaud. Dec 2002
Rs = i + (Rm-i) + Rs = Expected return on the security
i = risk-free return
Rm= Expected return on the market
= Cov(s,m)Var(m)
Rs = Expected return on the security
i = risk-free return
Rm= Expected return on the market
= Cov(s,m)Var(m)
