Credit Risk related risk factors became (more) material (e.g. Bond/CDS Basis, Correlation-Risk)

Underestimation of migration risk

Misapprehension of default and jump-to-default risks

Modelling shortcuts proved incorrect - misuse of proxies in the pricing and risk measurement of securitisation

products... they are not bonds !

Misapprehension of correlations and volatilities

Misapprehension of liquidity

Number of regulatory Backtesting-Outliers increased significantly

120 Outliers for 15 banks with internal model approval in Germany in 20081

Risk factors

Internal Model Approach - Generalities

g

Risk factors

Factors deemed relevant in pricing function should be included in VaR model (otherwise justification to Supervisor)

Non-linearities for options and other relevant products (e.g. mortgage-backed securities, tranched exposures or n-th-to-default credit derivatives)

Correlation risk

Basis risk (e.g. between credit default swaps and bonds)

Proxies used should show a good track record for the actual position held (i.e. an equity index for a position in an individual stock)

Scaling methodology (e.g. square-root of time) for the holding period (1-day to 10-day) is allowed but must

be justified periodically to the supervisors

Use of weighting schemes is more flexible as long as the resulting capital requirements is not reduced

Update of data sets should be made, at least, on a monthly basis (process allows more frequent updates)

Hypothetical (or clean) backtesting is made mandatory for validation

Stress Testing (use of more recent examples for Stress testing scenarios)

1. CRD III requires in addition reverse stress testing

2. CRD III requires institutions to calculate overshootings consistently on the basis of hypothetical (clean) and actual (dirty) back-testing. The plus-factor is determined by the higher of the number of overshootings under hypothetical and actual changes in the value of the portfolio.]

Specific Risk

All material components of price risk must be captured

Surcharge models are no longer allowed

Internal Model Approach – Specific Risk

Surcharge models are no longer allowed

Specific risk of equity risk positions

Model event risk (e g merger break ups/takeovers) at 99% 10 day horizon

Model event risk (e.g. merger break-ups/takeovers) at 99%, 10 day horizon

For securitisation positions and n-th-to-default credit derivatives

Specific risk capital charge is based on the standardised method

Specific risk capital charge is based on the standardised method

Positions may be included in VaR but a standardised charge is required anyway

Limited exception for correlation trading portfolio

Limited exception for correlation trading portfolio

 Comprehensive Risk Measure

 Floor equivalent to 8 % of the standardised methodq

Market risk modelling – Part b

Stressed VaR

Intended to replicate a value-at-risk calculation that would be generated on the bank’s current portfolio if the

relevant market factors were experiencing a period of stress

Internal Model Approach – New charges

Applied to all positions covered under VaR

- Consistent with the VaR (99%, 10 days) for the current portfolio

Model inputs calibrated to historical data

Continuous 12-month period of significant financial stressp g

Relevant to the bank’s portfolio

Approved by the supervisor

Regularly reviewed

No particular technique is prescribed for VaR

(i.e. parametric, historical or Monte Carlo); hence, different techniques might be used to deliver a SVaR

 For example, banks should consider applying anti-thetic data, or applying absolute rather than relative volatilities to deliver an appropriate stressed value-at-risk1

At least, a weekly calculation

Capital requirement

Expressed as :

 "sVaRavg"= average SVaR number over the last 60 business days (i.e. 12 results)

 Multipliers (mc and ms ) are set by supervisors, minimum 3 plus [0 - 1] depending on the backtesting results based on the VaR (not the SVaR)2

1. This is not specified in the CRD III

(22)

Market risk modelling – Part b

Incremental Risk Charge

Who?

Banks that model specific risk for traded debt instruments (interest rate risk positions)

If not met standardised method

Internal Model Approach – New charges

g

If not met, standardised method

If met, default and migration risks could be excluded from VaR/SVaR to avoid double counting

What?

Default and migration risks

All positions subject to a capital charge for specific interest rate risk,BUT

Not securitisation positions nor n-th-to-default credit derivatives (even if hedges)

Subject to supervisory approval, all listed equity positions and derivatives positions based on listed equities, consistently with internal risk management framework

Not CRM hedges, if applicable

How?

No prescribed methodology

Soundness standards comparable to IRB (99,9 % ; 1 year)

C t t l l f i k ti

Constant level of risk assumption

Rebalancing positions thereby maintaining initial risk level (i.e. equivalent risk characteristics than original position)

Rebalancing frequency is driven by the liquidity horizon of a given position

Banks may assume a 1-year constant position, if applied consistently

Incremental Risk Charge….Detailed guidelines

Soundness of standard

Internal Model Approach – New charges

g

g

under the assumption of a constant level of risk,

and adjusted where appropriate to reflect the impact of liquidity, concentrations, hedging, and optionality

Constant level of risk

The constant level of risk assumption implies that a bank rebalances its trading positions over the one-year capital horizon in a

The constant level of risk assumption implies that a bank rebalances its trading positions over the one year capital horizon in a manner that maintains the initial risk level

This means incorporating the effect of replacing positions whose credit characteristics have improved or deteriorated over the liquidity horizon with “original” positions

l f i k

Soundness of standard/Constant level of risk

The frequency of the assumed rebalancing must be governed by the liquidity horizon

The liquidity horizon represents the time required to sell the position or to hedge all material risks covered by the IRC model in a stressed market

A bank can assess liquidity by position or on an aggregated basis (“buckets”)

A bank can assess liquidity by position or on an aggregated basis ( buckets )

The liquidity horizon for a position or set of positions has a floor of three months

The liquidity horizon is expected to be greater for positions that are concentrated

A non-investment-grade position is expected to have a longer assumed liquidity horizon than an investment-grade position.

A bank may elect to use a one-year constant position assumption

A bank may elect to use a one year constant position assumption

Correlation/Diversification/Concentration

A bank’s IRC model must include the impact of clustering of default and migration events (-> correlation/dependence within IRC)

Diversification between default or migration events and other market variables is not reflectedg

Significant basis risks has to be captured

Risk because of a maturity of the instrument shorter maturity than the liquidity horizon has to be captured

Residual risks resulting from dynamic hedging strategies must be reflected

Optionality must be captured

Validation

Model assumptions and inputs must be regularly validated (LH, CH, correlation, …)

Back testing will not be possible. Accordingly, validation of an IRC model necessarily must rely more heavily on indirect methods including but not limited to stress tests, sensitivity analyses and scenario analyses

Banks should develop relevant internal modelling benchmarks

Review of Quantitative Impact Studies

TBG-QIS 2009:

“Excluding the so-called correlation trading portfolio, the study concludes that the changes to the market

risk framework will increase average trading book capital requirements by two to three times their current

risk framework will increase average trading book capital requirements by two to three times their current

levels, although the Committee noted significant dispersion around this average”

TBG-QIS 2009/2010: Adjustments to the Basel II market risk framework announced by the Basel Committee (18

June 2010):

June 2010):

“As a result of these revisions, market risk capital requirements will increase by an estimated average of

three to four times for large internationally active banks”

Conclusion - Q&A

Wrapping Up

g

New market risk framework as imperfect solution with a noble scope

Lacking intellectual consistency

“Citiboys” would have preferred a simpler solution

Potential damages for some trading activities

Weakening the importance of VaR for capital management purposes

Changing shape for risk management profession

Swelling costs for financial institutions

Any questions?

Appendix 1

Metrics for calculating regulatory capital for market risk

The regulatory framework distinguishes between general and specific market risk:

Specific market risk relates to the idiosyncratic risk affecting exposures to individual issuers

General market risk relates to the systematic risk affecting the overall market

General Market Risk

Specific Market Risk

General market risk relates to the systematic risk affecting the overall market

The total market risk of a (portfolio of) position(s) is the sum of its idiosyncratic and systematic components

Standardised Measurement Method

Specific risk: EQUITY

Preferential treatment for liquid equity positions removed

8% specific risk capital charge for all equity positions

Specific risk: (RE-) SECURITISATIONS

Standard risk weights according to banking book regulation

SFA, concentration measure or deduction for unrated positions

 Supervisory Formula Approach based on PDs and LGDs for all underlying exposures derived from IRBA or from IRC

Capital requirements for long and short positions

 Max (long, short) for a two year transition period

Specific risk: CORRELATION TRADING PORTFOLIO

Definition correlation trading portfolio

Max (long, short) on a permanent basis

Appendix 2 The correlation trading portfolio

Standardised Measurement Method

Securitisations and n-th-to-defaults that meet the following criteria:

All reference entities are single-name products, including single-name credit derivatives, for which a liquid two-way

market exists. This will include commonly traded indices based on these reference entities

A two-way market is deemed to exist where there are independent bona fide offers to buy and sell so that a price

A two way market is deemed to exist where there are independent bona fide offers to buy and sell so that a price reasonably related to the last sales price or current bona fide competitive bid and offer quotations can be determined within one day and settled at such price within a relatively short time conforming to trade custom

No resecuritisations and no derivatives of securitisation exposures that do not provide a pro-rata share in the

proceeds of a securitisation tranche (e.g. options and LSS)

Positions which reference an underlying that would be treated as a retail exposure, a residential mortgage

exposure or a commercial mortgage exposure under the stan-dardisedapproach to credit risk are not included in

the correlation trading portfolio Positions which reference a claim on a special purpose entity are not included

the correlation trading portfolio. Positions which reference a claim on a special purpose entity are not included

either

Hedges which are neither securitisation exposures nor n-th-to-default credit derivatives and where a liquid two-way

market as described above exists for the instrument or its underlyings may be included
