What-If

What is the What-If?

The What-If functionality is a Solution add-on to the ActiveViam platform. It provides a consistent approach (including auditing and memory management) across all business solutions developed on top of the ActiveViam platform and is extendable and customizable. For example, the software allows a user to test the impact of a variety scenarios that effect a bank’s risk-based capital charge.

How does it work?

On daily basis, the production data set is loaded from a variety of sources (i.e. trade, reference, market data) and stored in an Atoti Server cube. This will serve as the master data set from which all the potential scenarios or simulations evolve.

Once the What-If is initialized, the software allows a user to apply certain changes to the risk data and parameters. These updates are reflected in a What-If branch of data that is created as an outgrowth of the master data set used to perform the what-if scenario.

In the screenshot, the capital calculations are displayed based on the data in the master branch, as well as in an experimental branch called WhatIf Fx DRW -> 0.3, having the parameter Fx Delta Risk Weight increased by a user from 0.21 to 0.3.

The What-If functionality avoids the need to re-create massive sets of data and wait for the results. Rather, incremental updates are performed on the existing data sets and only those metrics that are impacted by any change in trade, reference, market data, etc., are refreshed.

The use-cases supported by Atoti CVA Risk Capital out-of-box¹:

• What-If simulations on supervisory parameters. Users may override values of supervisory parameters and immediately visualise the impact on screen. Please refer to the Parameter Sets Widget documentation to learn more.

• What-If on sensitivities. Users may upload stress test sensitivities into an experimental branch and evaluate stressed risk numbers. Please refer to the Sensitivity Upload Widget documentation to learn more.

Any other What-If use-cases and features would be developed on a client implementation project and would not be part of Atoti CVA Risk Capital.
