Traditionally the core of bank margin is in risk management. The core of risk management is data.. thus Banks have been the among the best data businesses (as IBM knows). Banks “learn” about their customers through bank interaction: payroll, card transactions, lending. This has helped banks make better risk decisions (both credit and fraud/identity). Within the bank data cycle the traditional use of data is for an internal benefit: risk and cross sale of the bank’s products and services (not that of consumers or merchants). However the “virtuous cycle of banking data” is very different from that enjoyed by Amazon and Google, both in the scale and type of data and consumer facing use.
