Took me a while but I’ve just finished Bank 3.0 by Brett King. Sounds the dullest subject in the world but the book was captivating. I couldn’t recommend it more. It expands – in great detail – on the Bill Gates’ quote from a few years ago, “Going forward we’ll all need banking, but will we need banks?”

The book analyses what consumers increasingly want from their banking – and how, as a result, the vast majority of banks are in danger of now losing their customer mindshare to the Apple’s, Google’s and PayPal’s of this world. It also questions why banks are so intent on defending their branch strategy, often at enormous cost, when their customers would be better served if that investment were directed to their mobile banking apps.

For those interested in how we’ll all manage our finances in future, New York-based Brett King paints a compelling picture. For the traditional retail banks, it’s a frightening one. This book alone must be driving up the value of the emerging challenger banks such as Atom and Starling.
