Module 1 - Unit 4 Risk Assessment 1: Introduction And Identification Flashcards
How would you define Risk Assessment?
The overall process of risk identification, risk analysis and risk evaluation
What is Risk Perception?
When assessing risk is important to be aware that different individuals in an organisation may hold different risk perceptions, known as “expert judgements”
What are the 3 risk assessment considerations?
Risk Identification
- What might happen?
Risk Analysis
- How likely is to happen?
- If it does, what might be the impact?
Risk Evaluation
- So what?
- Is it within our risk appetite and tolerance?
What is VaR?
VaR is a measure of the potential loss in a portfolio over a given time horizon within a given confidence interval.
X - probability or percentage (confidence level we are seeking)
V - value at risk (the amount we expect to lose)
T - time period we are considering
What is expected shortfall?
Expected shortfall, sometimes called ‘expected tail loss’ it is defined as the average loss that could occur in excess of the loss calculated by VaR over a time period and using the same confidence level. Expected shortfall overcomes VaR limitations.
What is stress test?
Stress testing and scenario analysis provide alternative to VaR and other risk measures. They explore reactions to small (sensitivity) or drastic (stressed) changed in conditions.
Stress testing and scenario analysis techniques are being used for:
• Assessing capital and liquidity requirements
• Understanding the dynamics of the risk environment and therefore providing a tool for decision making
• Challenging the output of VaR or other models
• Informing senior management
How are risks classified?
Risks are classified as:
• short-term - risks with imediate impact (operational activities or market changes)
• medium-term - in bank reporting medium term is between 1-3.5 yrs
• long-term - in bank reporting over 3-5 yrs
What is Monte Carlo simulation?
Monte Carlo simulation is a model used to predict the probability of different outcomes when the intervention of random variables is present.
Explain the top down risk
A top down risk assessment exercise tends to focus on risks related to strategy, tactics operations and complicance (STOC)
Explain the bottom-up risk
A bottom-up risk assessment tends to focus on risks identified as compliance, hazards, control and opportunity.
What is the variance - co variance method? (Known as the Risk Metrics approach)
Variance is a measure of the variability or spread in a set of data (e.g., market returns)
Covariance is a measure of the extent to which corresponding elements from two sets of data move in the same direction.
• results are normally distributed
• correlations between risk factors are constant
• sensitivity to changes of risk factors is constant
What is the historical method?
The historical method re-organised actual historical returns.
What is the Reverse Stress Testing?
The stress tests start from the point at which the businss plan becomes unviable. The process is intended to drive an understanding of what might bring a business down.
What is the BOW-TIE tool?
The bow-tie tool purpose is to demonstrate that sources of risk can lead to events that have consequences. The diagram helps to focus on the precise nature of each risk and provides a logical basis for analysing the context, causes and consequences.
