Basel I

Initiation: Herstatt bankruptcy 1974

Publication of new rules 1988, Implementation: 1992,

Minimum capital requirement = amount of credit x 8 % x percentage

weight of risk class

Risk classes and percentage weights: no discredition for banks

• 0 % for sovereign bonds of OECD-countries (zero!)

• 20% for interbank credits (1 million) within OECD countries (16 000)

• 50% for collateralized real estate credits (40 000)

• 100% for other credit engagement including loans to corporations (80000)

Important elements

1

From Basel I to Basel III Dorothea Schäfer 4

Basel I

1. Common equity capital and retained earnings (core (Tier 1) capital)

2. Additional internal and external resources of the bank

(supplementary capital, long-term liabilities, specific provisions)

Tier 1 capital: core Tier 1 capital plus other instruments, e.g. non-

redeemable non-cumulative preferred stock

Loss taking: Common equity capital and retained earnings

Weird: other instruments than loss taking instruments qualify as bank

capital

Definition of capital within Basel I

1

From Basel I to Basel III Dorothea Schäfer 5

Basel I

• Only four risk categories

• Independency of risk weights of borrower‘s solvency

and liquidity

• Cross-subsidization of loans and credits (good

borrowers subsidize bad borrowers)

Main critique of Basel I

2004: publication of Basel II framework

2007: implementation

Main elements

1. Basically no change in definition of capital

2. Introduction of individual risk weights

1. Ratings (ECAI External Credit Assessment Institution, e.g S&P, Moody’s,

Fitsch)[standard approach]

2. Own calculations (bank itself assesses risk)[IRB approach]

3. Calculation of a bank’s required capital

Basel II

“The European CRDs have introduced […] a risk weight of 0% for

“exposures to Member States’ central government […].

[…] instead of confining the zero risk weight to the standardised

approach, (the CRDs) permit a generalised zero risk weight through the

so-called “IRB permanent partial use” rules”

IRB permanent partial use: IRB in general except for sovereign debt. (Speech of Hervé Hannoun, Deputy General Manager Bank for International Settlements, at Financial

Stability Institute High-Level Meeting Abu Dhabi, UAE, 26 October 2011 )

Incentives

2

Dorothea Schäfer 12

From Basel I to Basel III

1. Investing in the zero risk weight debt of EU member

states

2. Minimum risk assessment with own models

3. Investing in highly rated securities (e.g super senior

tranches of US subprime CDOs)

4. Installing off-balance sheet vehicles with no capital

requirements (continues from Basel I, no

counterbalancing regulation present)

Basel II

Consequence

2

Dorothea Schäfer 13

From Basel I to Basel III

1. Growing of total assets without additional capital

2. Bank got bigger and bigger

3. Excessive leverage and extremely low leverage

ratios

4. Expansion of off-balance sheet vehicles

Basel II

Basis for such incentives

Leverage effet in combination with bonuses which are linked to the return

on equity

More anectotic evidence: the Swedish real estate case

2

Dorothea Schäfer 20

When the Basel 2 accord came into effect in Sweden in 2007, Sweden’s

largest mortgage lenders were authorized by FI to use internal models to

calculate the risk weights in their credit exposures. The result of the

introduction of the models was that risk weights for Swedish mortgages

dropped sharply, and many of the largest players now have average risk

weights down at around 5 per cent for these exposures. This can be

compared to risk weights of 50 per cent in the regulations applicable until

2007 – the Basel 1.” (Finansinspektionen – Memorandum Nov 26, 2012)

Basel II

Conclusion for Basel II

2

From Basel I to Basel III Dorothea Schäfer 26

Risk weights in Basel II • have enabled banks to get larger and larger without increasing the amount of

loss-absorbing equity capital, • made banks more vulnerable, • have contributed to the European financial crisis

• because of the short distance of many large European banks to default and

• the therefore high probability that sovereign EU/Euro member states have to accumulate more debt in order to help their banks

In addition: lobby groups use risk weights to fight for lower ones (e.g. sme loans, real estate loans, energy investments). This may decrease credit costs on the micro level but decreases stability on the macro level (race to the bottom)

Basel III

Is it the answer to these problems?

3

Dorothea Schäfer 27 From Basel I to Basel III

Basel III

Important elements

3

From Basel I to Basel III Dorothea Schäfer 28

• Narrower definition of eligible capital (focus: loss absorption)

• Increase of capital requirements

• Banks in general

• Global systemically (Sifis), domestic systemically important

financial institutions

• Leverage ratio

Still dominant: risk weighting is basis for capital requirements

Struggle with US about role of rating agencies

Basel III

Important elements

3

From Basel I to Basel III Dorothea Schäfer 29

• Liquidity coverage ratio and net stable funding ratio

• Liquidity for 30 day of stress (recently postponed 2015 to

2019)

• NSFR: fighting of maturity mismatch (goal: liquid for one

year)

• Payment rules (bonus systems)

(CRD IV: EUP and EUC struggle)

Basel III

Capital requirements

3

From Basel I to Basel III Dorothea Schäfer 30

• Core capital (Common equity and retained earnings)

• Banks in general (7 %, including max. CCB: 9.5 %)

• from 2% to 4.5%

• capital conservation buffer: 2.5 % (supervisory authorities impose

constraints)

• Counter cylical buffer (CCB) from 0 to 2.5 %

• Sifis: on top between 1% and 2.5 % (depends on

importance) + 1% in addition for the highest class Sifis (in

discussion)

Reminder: Tier 1 capital ratio of German banks 11.9 % (IMF)

Basel III

Capital requirements

3

From Basel I to Basel III Dorothea Schäfer 31

CRD IV: EUP and EUC struggle about eligibility of additional

buffers (Sweden, UK)

EUP: fear of competitive advantage for buffer countries

Weird because for years lower capital requirements than the

“strong Basel II” rules were labelled as competitive advantage

(e.g. German banks complained a lot about US bank not

following the Basel II rules)

Basel III

Capital requirements

3

From Basel I to Basel III Dorothea Schäfer 32

Leverage ratio : 3 percent in 2019

• Too low for large banks

it implies a leverage of 33 x the required capital,

no constraint for the growth in size (no constraint for mh)

• Required capital is broader defined than the core capital,

therefore: required core leverage ratio is actually lower

• Too late

• Not exactly clear: mandatory or only ratio for observation

Basel III

Final remark

3

From Basel I to Basel III Dorothea Schäfer 33

Basel III is not the answer to the identified problems

• It does not effectively constrain the leveraged growth model

of banks

• It does not effectively constrain the banks’ discretion about

the risk weighting and the capital requirements

• It does not effectively remove the management’s incentive

to build on the leveraged growth model

• Limitation of the moral hazard (mh) problem of Sifis: highly

questionable
