Banking Week 2 Flashcards
Objectives of risk management
Maintaining solidarity (strong capital position )
To ensure sufficient liquidity
Duty of care for clients (behavioural and advice)
Achieving efficiency (sound business )
Capital and liquidity
Capital (own funds)- can be used as a buffer for losses
Risks
credit risk,market, operational, interest rate
Other capital risks : business, reputational, strategic , compliance
Liquidity risk - bank run, market stress
Amounts are too large to mitigate with capital
Credit risk
The potential that a banks borrower or counterpart will fail to meet its obligations in accordance with agreed terms
Days past due (eg 90 days suggested by EBA) can be a indicator for default
Risk with high impact (most important ?)
Mitigated with collateral (eg house)
Credit products require a lot of capital
Different borrowers (eg retail v commercial) have tailor made products :
- Maturity (liquidity or interest)
- Repayment method (interest only / bullet / linear annuity)
- Collateral
Credit approval process (analysis if borrower will pay back the money )
- Loan value
- Loan to income
- Other collateral
- behaviour of the borrower (payment behaviour, social media )
5Cs of credit management (Character, capacity, capital, collateral, conditions )
Calculating credit risk (required capital )
-Exposure at default (EAD): expected exposure to a particular obligor at time of default
Amount may be more by drawing rights
- probability of default (PD)- likelihood that a borrower will default within a certain timeframe
- Probability within 1 year
- Designated as default by special credits department
- 90 days overdue with interest payments
Loss given default (LGD)- percentage loss over the total exposure when banks counterparty falls into default
Loss at time of the default, taking into account enforcement of collateral
-Expected loss (EL,€) = expected loss at time of default -EL= PDLGDEAD
Calculating required capital credit risk
Expected loss - normal cost of doing business covered by provisioning and pricing policies
Unexpected loss -potential unexpected loss which capital should be held
Stress loss - potential unexpected loss which is too expensive to hold capital against- leads to insolvency
Standardised approach - banks must use a set of prescribed risk weights to determine their capital requirements for credit risk ; risk weight is determined by external credit rating of counterparty (eg AAA, or is unrated then a risk weight of 100% is assigned )
-Internal rating based approach (AIRB): 85% of RWA has to be calculated by the AIRB approach
Banks are allowed to use internal models to determine the PD,LGD and EAD
If the models show that risks in a portfolio are limited, the RWA will be lower resulting in lower capital requirements
RWA = EAD*f(PD,LGD,Maturity)
Market risk
Market risk is the risk that the value of an investment will decrease due to movements in market factors such as:
Interest rates
Foreign exchange rates
Equity prices
Commodity prices
Banks can use internal models or the standardised approach to calculate RWA for market risk
Common method to monitor market risk is value at risk (VaR)
Loss taken :
Direct P&L (fair value)
In reserves, comprehensive income (after sale through P&L)
Hold to maturity
Market risk VaR historical method
Example
95% confidence level we expect our worse daily loss will not exceed 4%
If we invest $100, we are 95% confident that our worst daily loss will not exceed 4$ ($100 x -4%)
Operational risk
Risk of a loss resulting from inadequate or failed internal processes and systems or from external events
Examples: internal fraud, external fraud, system failure
Calculation - basic indicator approach, standardised approach and advanced measurement approach to calculate risk and RWA.
Under advanced measurement approach banks can use internal models based on the frequency and impact of the risk
Eg model in a bank shows fraud happens ten times a year
Average loses due to external fraud is 50,000 therefore expected loss from external fraud is 10*50,000 = 500,000
Measuring operational risk
Basel III mínimum capital requirements for main risk types
- credit risk
- market risk
- operational risk
Operational risk - basic indicator approach , standardised approach, advanced measurement approach
What are some other risks
Business risk
Reputational risk
Concentration risk
Strategic risk
Legal risk
Compliance risk
