In the heart of software development, in the city Brno, we launched a blog about IT.
I would like to discuss a problem with you that I see repeatedly encountered when performing complex, multifarious tasks such as bank stress tests: the lack of ability to concentrate on the "bigger picture" and the consequences this has on the analyst.
When we started with the implementation of IFRS9 standard, we had about a year to design and come with working and hopefully an extendable and robust solution. Since most of our developers are comfortable with Java and we built other projects using this language, the decision to built a core of application on Java Spring framework was easy.
We have created a unique solution for recurring stress tests in credit risk Raiffeisen Bank International, which allows us to define our own test scenarios for simulation of portfolio development and calculations of individual Risk Parameters RWA or ECL. Our application was successfully used for EBA stress tests in 2018 and continues to be extensively used for other stress testing needs by internal or required controllers.
In early 2018, a new methodology for the calculation of provisions for Expected Credit Losses (or ECL) under IFRS9 for the banking sector came into force. Our team was tasked with implementing a solution for the retail credit exposures of Raiffeisen Bank International (RBI). The calculation is used to check the plausibility of results provided by each RBI subsidiary bank.
