Equity Capital(= Assets - Liabilities)

Liabilities(Debt Capital)

Assets

Banks balance sheet

• Optimise return on equity capital: RoE as key indicator for investors and shareholders

• Limitations from regulator: Minimum required equity capital compared to business activities

- Solvency

- Stable financial systems, protection of local depositors

Main internal steering factor: Optimisation of limited resource equity capital

4/41

Credit Risk

Unexpected losses due to default of borrowers, counterparties, emittents

e.g.subprime crisis

Operational Risk

ngs Bank,

Unexpected losses due to failures of Systems, processes, human or technical errors, external events and legal processes

e.g. BariSocGen

Market Risk

arket movements of Unexpected losses due to mrisk factors like interest rates, stock and currency prices

e.g.new economy crash

Liquidity Risk

to repay liabilities

costs

to sell assets

Unexpected losses due to:a) unability

b) higher refinancing

c) lacking market depth

Risks of banking business

Risks unavoidable

Challenge: Detect, measure and manage true risks adequately to prevent unexpected losses !!

No Risk no Business !

Regulatory goals

Basel II Goals

• Aligning regulatory capital requirements more closely to the underlying risks

• Incentives to improve internal risk managementmore forward looking

• Risk adequate pricingif higher/lower risk than higher/lower margins

Basel I

is/was not adequate formodern risk situation.

14/41

Credit Risk development: Basel I and Basel II Standardansatz

Simple rule:

Capital / Risk Weighted Assets > 8%

Capital = RWA * 8%

~ Exposure * Weighting Factor

e.g. 20% for OECD* countries

*Organisation for Economic Co-operation and Development

NO credit rating (PD)

NO portfolio effects (diversification/concentration)

15/41

Basel II: Advanced Internal Rating Based Approach (AIRB)

Simple rule:

Capital / Risk Weighted Assets > 8%

Capital = RWA * 8%

~ Exposure * K (PD, LGD, Maturity)

Probability of Default

Still no portfolio effects (diversification/concentration)

but

Loss given Default

Analysis of balance sheet (quantitative model)

Analysis of historical defaults and crisis in the banking sector (quantitive model)

Qualitative Analysis by relationship manager and credit risk analysts to adjust quantitative model

Key Indicator: Probability of support by shareholders and/or government !

Internal determination of default riskGeneral approach:

Internal Determination of banks probability of default (PD) and loss given default (LGD):

Credit Risk Portfolio Model

Issues:

Different portfolio models on the market

BASEL II

Pillar 1: Calculation of regulatory capital for• Credit risk (AIRB-Ansatz)• Operational risk (AMA Ansatz)• Market risk (internal GS I model)

Pillar 2: Supervisory review process (SRP)4 principles:• supervisory review process• regulatory advices• regulatory transparency• specific topics within the SRP

Pillar 3: Market disciplineQualitative&quantitative disclosure of:• scope of application• capital structure• adequacy of capital resources• taken risks

Minimum requirementsfor Risk Management(MaRisk = national implementation)

Operational risk has always been there and lies at the heart of a lot of high losses and even bankrupticies Barings Bank, SocGen…

Operational Risk

Operational Risk means the risk of loss resulting from inadequateor failed internal processes, people and systems or from externalevents, and includes legal risk

Enough losses to care about it!

Benefits from optimising processes, efficient controls and transparent loss and risk analyses are not just prevention of catastrophic losses but also leads to lower costs in the normal business running

Regulator forces it now with OpRisk calculation requirements under Basel II

20/41

Methods to calculate OpRisk capital charges

The Basic Indicator Approach • Simplest of the three approaches• Default option for smaller banks

• Straightforward calculation based on the firms' income

The Advanced Measurement Approach • Highest capital relief and highest positive impact on bank processes but inevidable more complex. • Under this approach each bank calculates own capital requirements, by developing and applying

its own internal risk measurement system• Bank must meet certain qualifying criteria• Risk measurement system must be validated by the regulator

The Standardized Approach• Calculations based on Income

• Different Percentages applying accross different business lines• Standardized Approach banks have to meet certain qualifying criteria to be able to take the

advantages of the approach
