An analyst at Forrester with expertise in the European consumer financial services sector, has published a report titled: "Why Google Bank won't happen, but a Google-powered financial services hub might".Oliwia Berdak said she wrote the report in response to a frequently asked question from her banking clients: "When will Google launch a bank and what will it look like?" Berdak has suggested in a blog that draws from her report that this is the wrong question, despite moves like Google's foray into digital wallets that have demonstrated the tech player' willingness to disrupt the "payments ecosystem". "Google won't become a bank - it's not another bank that people want - but it could easily become a financial services hub to facilitate the relationship between consumers and providers of financial services," Berdak wrote."It's the assumptions that are faulty here that reveal precisely the type of legacy mindset that makes many retail banks so vulnerable to disruption," Berdak wrote.What's most important, she asserted, is to recognise that digital disruptors like Google are disruptive precisely because they don't play by the rules.  "What does 'not playing by the rules' mean in this context? It means not being welded to a business model based on interchange fees, for example," Berdak said. "It means not focusing on loans and deposits but rather on adjacent customer pains that software can resolve."For a firm that uses information to solve problems, a logical next step is to use digital assets such as product, consumer and transaction data to deliver financial advice and tailored product recommendations. "It also means offering something just so you can get consumer data you need to improve your business.  In retail financial services, developing a better global payment network, providing affordable financial advice that millions of customers desperately need or simply getting access to transaction data are all sufficient motivations for firms like Google to get involved," Berdak suggested.
