How big data might mean better business for big banks: interesting vision how banks and credit card companies can use publicly available data and big analytics to separate bad from good risks for the retail lending business. There are some more links in that article that are worth following.

I think some might already be using similar technology to vet new very rich private banking customers (identify those where the reputation risk of serving them might be too big) or help with CRM for the existing top few hundred wealth management clients. But scaling this to thousands and millions of potential customers is a whole different challenge for big analytics, that I’m eager to see how soon they can make it work economically.
