In Credit Risk management, it is common practice for banks to use financials for assessing the creditworthiness of large and mid-corporates, with the drawback of being outdated by the time the credit review takes place. This paper proposes the use of real-time transactional data to circumvent this issue. This process can be further improved by setting in place teams dedicated to data management and preparation with the benefit of centralising the information used for other purposes, e.g. modelling, loss collection, monitoring, validation.
