AGENDA:
Functions of bank capital;
Definitions of Bank Capital, leverage ratio;
Structure of BASEL

2
Bank capital and minimum ratios;
Risk-weighted assets for credit risk, market risk and operational risk
Basel 2 and Basel 3.

Слайд 3

Importance of Bank Capital
Absorb unanticipated losses and preserve confidence of

the FI;
Protect uninsured depositors and other stakeholders;
Protect FI owners against increases in insurance premiums and liquidity premiums;
Acquire real investments in order to provide financial services.

Слайд 4

Two DEFINITIONS of capital:
Economic = difference in the market value

of assets and liabilities.
Regulatory = defined capital and ratios are based in whole or part on historical or book value with the exception of the investment banking industry.
The deviation of BV from its true MV depends on:
Interest rate volatility.
Examination and enforcement.
MV of Equity per share = MV of shares outstanding
Number of shares
BV of Equity per share = (Par Value of Equity +
Surplus Value +
Retained earnings +
Loan Loss Reserves)
Number of shares
MV/BV = the degree of discrepancy between the MV and BV of FI’s equity.

Слайд 5

Problem 1

Слайд 6

Why do FI and Regulators are against market value accounting?
Difficult to

implement, especially for small commercial banks with large amounts of non- tradable assets when it is impossible to obtain accurate market prices;
An unnecessary degree of variability of earnings;
FIs will be less willing to have exposures in long-term assets such as mortgage loans, C&I loans because these assets will have to be continuously marked-to-market and they will reflect quality changes.

Слайд 7

Leverage Ratio
Banks are required to meet minimum capital standards on both

a simple leverage basis and a risk-adjusted basis.
Problems with leverage ratio:
Market value may not be adequately reflected
Fails to reflect differences in credit and interest rate risks
Off-balance-sheet activities escape capital requirements
Allows regulatory arbitrage
Banks are able to increase their asset risk without changes in the ratio

Слайд 8

CAPITAL ADEQUACY: Basel 2
OBJECTIVES:
Development of more internationally uniform prudential standards

for the capital required for banks
Promote convergence of national capital standards , removing the competitive inequalities among banks;
Develop a more meaningful link between banks on- and off- balance sheet risk exposures and the capital supporting them;
Enhance market discipline through better information about banks' risk profiles, risk measurement techniques and capital;
Develop a framework that was adaptive to rapid financial innovation.

Слайд 9

BASEL 2 (adopted in 2007)
The new accord is based on 3

pillars:
Pillar 1: Minimum capital requirements for credit risk, market risk and operational risk.
Pillar 2: Supervisory review of capital adequacy.
Pillar 3: Market discipline.

Слайд 10

STRUCTURE OF BANK CAPITAL:
TIER 1 = Issued and fully

paid common stocks
(CORE CAPITAL) + Non-cumulative perpetual preferred stocks
+ Retained earnings
+ Minority interest in equity accounts of consolidated subsidiaries
+ Disclosed reserves
Deductions: – Goodwill
– Increase in equity capital resulting from a securitization exposure

Слайд 11

STRUCTURE OF BANK CAPITAL:
TIER 2 (SUPPLEMENTARY CAPITAL) =
+ Cumulative

perpetual preferred stocks
+ Undisclosed Reserves
+ Asset Revaluation Reserves
+ General Loan Loss Reserves
+ Hybrid (Debt/Equity) Capital Instruments
+ Subordinated long-term debt
Other Deductions: 50% from Tier 1 and 50% from Tier 2 capital:
- Investments in unconsolidated subsidiaries engaged in banking and financial activities;
TIER 3 (to cover market risk only) = subordinated short-term debt
TOTAL CAPITAL = TIER 1 + TIER 2 + Tier 3 - Deductions

Слайд 12

MINIMUM RATIOS:
LIMITS AND RESTRICTIONS:
Tier 2 capital cannot exceed Tier 1

capital (maximum split is 50/50);
Tier 3 capital cannot exceed 250% of Tier 1 capital;
Subordinated long-term debt is limited to 50% Tier 1 capital;
Amount of loan loss reserves (Tier 2) is limited to 1.25% of risk adjusted assets;
Asset revaluation reserves are subject to a discount of 55% to the difference between the historic book value and market value.
Tier 1 capital ratio = Tier 1 capital _____ ≥ 4%
Total Risk – Weighted Assets
(Credit risk + Market risk + Operational risk)
Total capital ratio = Tier 1 + Tier 2 + Tier 3_ ≥ 8%
Total Risk – Weighted Assets
(Credit risk + Market risk + Operational risk)

Слайд 13

RISK WEIGHTED ASSETS
Total Risk-weighted Assets (TRWA) are determined by multiplying the

capital requirements for market risk and operational risk by 12.5 (in Kazakhstan we apply 8.3 for banks and 10 for bank holding) and adding the resulting figures to the sum of risk-weighted assets for credit risk.
Approaches to measure risks:

Слайд 14

ESTIMATION OF RISK WEIGHTED ASSETS FOR CREDIT RISK: Standardized approach
R.W.

ASSETS = R.A.B/S ASSETS + R.A. Off B/S ASSETS
n
R.W. B/S ASSETS = ∑ Risk Weight i x Asset amount i
i=1
R.W.Off B/S ASSETS:
1) Amount j x Convergent factor j = Credit Equivalent Amount j (CEAj)
m
2) R.A.Off B/S ASSETS = ∑ CEAj x Risk Weight for B/S Assets
j=1
n m
R.W. ASSETS = ∑ RWi x Ai + ∑ CEAJ x RWJ
i=1 j=1

Слайд 15

Standardised approach (use outside credit rating)
On Balance sheet assets are allocated

into weighting bands according to ratings of rating agencies separately for sovereign, interbank and corporate exposures.
For sovereigns and their central banks the following risk weights are proposed:
For corporate lending and claims on insurance companies:

Слайд 16

EXAMPLE: Step 1. Calculate Risk-Weighted on-Balance Sheet Assets
Each bank assigns its

assets to one of five categories of credit risk exposure:

Слайд 17

Step 2. Calculate Credit Equivalents for Off-Balance sheet Items other than

OTC Interest Rate and Foreign Exchange Contracts.

Слайд 18

Step 3. Calculate Credit Equivalents for OTC Interest Rate and Foreign

Exchange Contracts.
Credit conversion factors for Interest Rate and Foreign Exchange Contracts in calculating potential exposure

Слайд 19

Step 4. Total Risk Weighted assets
Risk-Weighted assets for credit risk =

75.5 $ mill + 23$ mill + 5.5$ mill =
104 $ mill
Total Risk –weighted assets = 104 + 12.5 (capital required to cover market risk and operational risk)

Слайд 20

Example continued: Calculate the minimum capital ratios if: Tier 1 =9$ mill

, Tier 2 = 7$ mill , Tier 3 = 16 Capital chargers for market risk is 8$ mill and for operational risk is 6$ mill.

Step 4. TRWA = 104 + 12.5(8+6) = 279
Step 5. Tier 1 ratio = 9/279 = 3.22%
Total ratio = 32/279 = 11.47%

Слайд 21

Internal rating based approach (foundation and advanced)
Banks are allowed to use

their internal estimates of borrower creditworthiness to assess credit risk in their portfolios.
Distinct analytical frameworks will be provided for different types of loan exposures.
The IRB approach relies on four quantitative inputs:
Probability of default (PD) = likelihood that a borrower will default over the given time horizon;
Loss Given Default (LGD) = the proportion of the exposure that will be lost if a default occurs;
Exposure at Default (EAD) = the amount of the loan that will be lost if a default occurs;
Maturity (M) = remaining economic maturity of the exposure.
Granularity scaling factor – higher capital will be required for more concentrated books than average.
For Retail loans there is only a single advanced IRB approach (no foundation alternative) and banks will set all inputs.

Слайд 22

Foundation and advanced approaches differ primary in terms of inputs that

are provided by banks or supervisors:

Слайд 23

MARKET RISK
April 1995, the Basel Committee announced amended proposals for the

treatment of market risk. According to this the following rules for the market risk were accepted:
Banks have choice in the computation of market risk: either they can employ the Basel building block method, or they can use their own models.
The internal model is Value at Risk, the worst potential loss with 99% confidence level over a 10 day period.
BIS requires banks to have additional capital beyond :
Previous day’s VAR × √10
Average Daily VAR over previous 60 days x a factor with min 3

Слайд 24

The pro-cyclicality of the VaR requirements
VaR to “an airbag that works

all the time, except when you have a car accident.”

Слайд 25

What is Stressed VaR?
The new component of stressed VaR is defined

by the highest:
Each latest available stressed VaR number (sVaRt-1)
An average of the stressed VaR measures over the preceding sixty (60)days (sVaRavg) multiplied my a multiplication factor ms

Слайд 26

Definition of Operational Risk
Risk of loss resulting from:
inadequate or failed
internal

processes
people
systems
or from external events
includes legal risk
excludes strategic and reputational risk

Includes, but not limited to, exposure to fines, penalties, or punitive damages resulting from supervisory actions, as well as private settlements

Слайд 27

Basel II Pillar 1 – Operational Risk

Слайд 28

Basic Indicator Approach (BIA)
Banks using the BIA must hold capital for

operational risk equal to the average over the previous three years of a fixed percentage (a factor α = 0.15 set by the Committee) of positive annual gross income.
Figures for any year in which annual gross income is negative or zero should be excluded from both the numerator and denominator when calculating the average.
K BIA = [∑ (GI 1-3 x α)] / 3
Gross Income (GI) = net interest income + net non-interest income
In Kazakhstan α = 0.12 (and α = 0.1 for a bank that is a subsidiary of the banking holding company)

Слайд 29

A Standardised Approach (SA)

In the SA, banks’ activities are divided into

eight business lines and different risk indicators ( a factor β set by Committee for each line) are set for different lines of business.
Capital charge for each business line is computed by multiplying a factor β for each line by the gross income for that business line, then summing.
Total capital charge is calculated as the three year average of the capital charges across each business lines in each year.
Note that the negative capital charges (resulting from negative gross income) in any business line may offset positive capital charges in other business line without limit.
KSA = {∑ years 1-3 max[∑ (GI 1-8 x β1-8),0] / 3
The values of betas are detailed below:
Corporate finance, trading and sales, payment and settlement – 18%;
Commercial banking, agency services – 15%
Retail banking, asset management, retail brokerage – 12%

PILLAR 2: Supervisory Review

SRP
(Supervisory Review Process)
ICAAP
(Internal Capital Adequacy

Assessment Process)

SREP
(Supervisory Review and Evaluation Process)

RAS
(Risk Assessment System)

Слайд 31

Supervisory Review
4 Key Principals of Supervisory Review:
Banks are required to

have a process for assessing their capital adequacy based on a thorough evaluation of their risk profile.
Supervisors would be responsible for evaluating how well banks assess their capital adequacy needs relative to the risk.
Supervisors should expect banks to operate above the minimum regulatory capital ratios.
Supervisors should intervene at an early stage to prevent capital falling below the minimum level required.

Слайд 32

The supervisory review process is intended not only to ensure that

banks have adequate capital to support all the risks in their business, but also to encourage banks to develop and use better risk management techniques in monitoring and managing their risks.
Note that there are some areas of risks that are not covered by the Pillar 1. Supervisors and banks are required to focus on these risks as well.
Pillar 1 does not cover:
the credit concentration risk;
interest rate risk of banking book;
business and strategic risk;
the business cycle effect.

Слайд 34

PILLAR 3: Market discipline
The goal is to encourage market discipline

through the enhanced disclosure by banks.
Effective disclosure (quantitative and qualitative) is essential to ensure that market participants can better understand bank’s risk profiles and the adequacy of their capital positions.

Слайд 35

Information to disclosure should include:
Capital structure and bank’s approach to

assess the capital adequacy of capital, capital ratios;
Risk exposure and assessment:
Credit risk, credit risk mitigation, counterparty credit risk;
Securitization;
Market risk;
Operational risk
Equities: disclosure for the banking book positions;
Interest rate risk in the banking book.

Слайд 36

Problems with Basel 2 revealed by the financial crisis 2007
Supervisory capital

ratios were not sufficiently forward looking and based on credit risk estimated from current bank accounts.
It led to the understatement of provisions for loan losses and to overstatement of bank asset values and bank capital (Furlong and Knight, May 24, 2010).
Capital regulation estimated the bank risks under the normal economic conditions and did not consider the cyclicality of the economy.
Systemically important financial institutions were exposed to greater risks due to the interconnectedness of their transactions.

Слайд 37

BASEL III
On 12th of November 2010 the G20 leaders officially endorse

the Basel III framework at the Seoul Summit
Implementation deadline: 1st of January 2013
Completion of the implementation: January 1, 2019
Basel 3 is the reaction to the Financial Crisis 2007

Слайд 38

Basel III squeezes capital
Predominant form of Tier 1 capital should

be common equity
Common equity = common shares and retained earnings
Tier 3 capital will be eliminated
Capital requirements:
Tier 1 Capital Ratio = 6%
Core Tier 1 Capital Ratio = 4.5%

Слайд 39

Conservation buffer
The purpose of the conservation buffer is to ensure that

banks maintain a buffer of capital that can be used to absorb losses during periods of financial and economic stress. Tool to promote capital conservation in the banking sector
Consists of Common Equity Tier 1 Capital
Set at 2.5 % of RWA on top of minimum capital requirements

Слайд 40

Countercyclical buffer
Countercyclical buffer
An extension of conservation buffer
Imposed by national authority to

curb excessive credit growth
To ensure to cover also macro-economic environment
The buffer will range between 0 to 2.5 % of RWAs
Calculation and publically disclosed with same frequency as minimum capital requirement

Слайд 41

Capital for Systemically Important Banks only
Systemically important banks should have loss

absorbing capacity beyond the standards.
Range from 1% to 2.5% of RWA
Implemented as an extension of the capital conservation buffer
Phased in from 2016 to 2018
