What is risk aggregation?
Risk aggregation is the process of combining the risks of different business units, products, or activities into a single risk measure. This allows organizations to better understand their overall risk exposure and make more informed decisions about how to allocate capital.
What is capital allocation?
Capital allocation is the process of deciding how much capital to allocate to different business units, products, or activities. This is done in order to maximize the organization’s return on investment while also minimizing its risk exposure.
Why are risk aggregation and capital allocation important?
Risk aggregation and capital allocation are important for a number of reasons, including:
- They help organizations to identify and manage their overall risk exposure.
- They help organizations to make more informed decisions about how to allocate capital.
- They help organizations to comply with regulatory requirements.
- They help organizations to protect their shareholders’ interests.
What are the steps involved in risk aggregation and capital allocation?
The steps involved in risk aggregation and capital allocation typically include:
- Identify the risks. The first step is to identify the risks that the organization faces. This can be done by conducting a risk assessment.
- Quantify the risks. Once the risks have been identified, they need to be quantified. This means assigning a numerical value to each risk.
- Aggregate the risks. The risks are then aggregated into a single risk measure. This can be done using a variety of methods, such as value at risk (VaR) or expected shortfall (ES).
- Allocate capital. The final step is to allocate capital to the different business units, products, or activities. This is done based on the riskiness of each activity and the organization’s risk appetite.

3. What are the different methods that can be used to aggregate risks?
There are a number of different methods that can be used to aggregate risks, including:
- Value at risk (VaR): VaR is a measure of the maximum loss that an organization can expect to incur with a certain level of confidence over a specified time period.
- Expected shortfall (ES): ES is a measure of the average loss that an organization can expect to incur over a specified time period.
- Monte Carlo simulation: Monte Carlo simulation is a statistical method that can be used to estimate the probability of different outcomes.
4. What are the different factors that should be considered when allocating capital?
The different factors that should be considered when allocating capital include:
- The riskiness of each activity.
- The organization’s risk appetite.
- The expected return of each activity.
- The availability of capital.
- Regulatory requirements.
