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
Idiosyncratic risk stabilised through adjusted through
risk adjusted capital reserves
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 MANAGEMENT IS TO
BALANCE THE CREATION OF VALUE WITH
EXPOSURE TO RISK FACTORS
Corporate Strategy
Shareholders
Funding Strategy
Debt, Bond holders
Risk Appetite
• Exposure
• Sensitivity
• Maximum Loss
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

Support Regulatory Compliance with information on
market behaviour in addition to statistical analysis
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

THE FALLACY OF MODERN FINANCE THEORY
Modern 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
Rs = i +  (Rm-i) + a
Rs = Expected return on the security
i = risk-free return
Rm= Expected return on the market
 = Cov(s,m)

Risk Intelligence is the New Efficient Frontier
Balancing shareholder value versus risk exposure depends on the firm’s
assessment of its aggregate sensitivity to risk factors under changing
conditions and on its ability to act upon it.
Regulators’ insights depend on risk intelligence.
