Case Study 1

Internal Model Approach (Basel)

We partnered with a Top Tier South African institution to design and deliver, a market leading platform for market risk measurement under the Internal Models Approach.

We delivered a first of its kind, configurable reporting framework, to deliver a wide range of risk analytics on an entirely configurable and automated basis. In addition to the core system, we also implemented a robust, clean reconciliation between risk and finance, with a granular PnL attribution, and risk-based backtesting process which provide clear visibility on risk model performance and adherence to trading mandates at individual desk levels.

Case Study 2

Front Office Modernisation

We partnered with a Top Tier South African institution to design and deliver, a market leading platform for market risk measurement under the Internal Models Approach.

A Tier 1 Bank engaged Riskworx to support them in the modernisation of their Global Markets business. Riskworx were responsible for refactoring the risk environment to improve the analytical capabilities provided by risk, the migration of positions, trading and the risk environment, and engagement with the regulators. Riskworx helped the client transform risk from a compliance function to an analytics platform that provided the business with insights into risks in their trading books and risks in other bank divisions.
