In 2016, Novum Bank set out to improve their scorecards in Spain for their consumer lending product. The bank's biggest underlying challenge was understanding the spending behaviours of their so-called 'thin-file' customers or clients with incomplete or non-existing credit histories. Novum Bank turned to Nordigen to test how insights from customer account information could solve the problem.
Over the course of four weeks, Nordigen and Novum Bank's Data Science team tested Nordigen's transaction categorization and behavioural scoring engines. The tests sought to determine whether they improved the overall accuracy of Novum Bank's scoring models.
The results revealed a 14 percentage point GINI coefficient uplift on top of all other existing data sources, including credit bureau data. The achieved results were sufficient to add Nordigen data points to Novum Bank's scorecard.
"Nordigen categorization adds significant value to our bank transaction data reports, by making them much easier to interpret. The categorization saves us significant time in contrast to finding out what each transaction means on our own," says Head of Portfolio Strategy at Novum Bank Group Filip ten Bruggencate.
"Novum Bank is on the cutting edge of technology and it is fascinating to work with their data science team. We strongly believe that the future of credit scoring is in the ability to leverage the opportunities of Open Banking. Our partnership with Novum Bank is a great example of this," adds Rolands Mesters, co-founder and CEO of Nordigen.
