Tech companies have disrupted retailing, media, transit and travel. Now the retail banking business model looks set to be transformed too. In Bye Bye Banks? James Haycock and Shane Richmond describe these startups, and to which areas of the banking industry they are laying siege. It shows that this assault is already well underway and that many incumbents are poised to be displaced, diminished and disintermediated. It draws on extensive research and on-and-off the record interviews with senior executives in some of the biggest banks. Haycock and Richmond conclude with the recommendation that traditional banks need to reinvent themselves by launching a 'Beta Bank': a lean, stand-alone organisation fit for the future for which they provide a ten-point operating model.
