Used Power Query to clean and visualise the data. Key insights: • Transaction failure rate is 60.0%, and may be responsible for an estimated £1,138,361 in unrecovered fee revenue leakage per period. • Automated/ATM devices show a fraud rate of 40.0% - the highest across all device types. This means that fraud losses are disproportionately concentrated in a single channel, amplifying portfolio risk. • The decline rate stands at 35.0%. Every declined transaction is a lost revenue event, with a compounding risk of customer attrition if legitimate transactions are affected. • Overall fraud rate is 20.0% of total transactions. At current volume, this translates to £39,311 in risk-adjusted exposure that is actively at risk of write-off.
