Case Study: Zagrebačka Banka increases cash loans by 15% with Oracle Exadata

Zagrebačka Bank Increases Cash Loans by 15% Within 18 Months of Advanced Analytics Platform Deployment

Zagrebačka Banka, Croatia’s largest bank, needed to improve statistical modeling and predictive analytics that previously took days to prepare, score, and build, while reducing the need to move large volumes of customer and financial data between systems. The bank wanted a faster, more agile way to support commercial and regulatory decision-making, using Oracle Exadata and the Oracle Advanced Analytics platform within Oracle Database.

Oracle Exadata helped Zagrebačka Banka consolidate predictive analytics in-database, enabling data preparation, model building, and scoring to run in seconds, minutes, or hours instead of days. The result was a 15% increase in cash loans within 18 months, 30% faster business analytics development and execution, and about 1,000 man-days saved in IT maintenance annually, while also improving prediction accuracy and regulatory reporting consistency.
