Financial Technologies are about to transform the way we bank, and they have just begun. Thirty years ago, the advent of communication technologies has revolutionized capitals markets and merely Finance. Financial products’ increased accessibility has made markets more liquid than ever, thus increasing trade, growth and development. Since then, human have created technologies which still was sketched in Fictions books few decades ago. Giant calculators, Internet, Nano-technologies and micro-computing are today about to change our entire world. Finance is not left aside, quite the contrary; it is actually deeply concerned by these technologies which progress exponentially and create opportunities until then unimaginable. Financial technologies’ companies, called FinTech embody this revolution’ outlooks. Global investments inside those start-ups have doubled from 12 billion in 2014 to 22 billion in 2015. They had just tripled from their 2013’s level (4 billion) and this trend may keep going yet a while. The last revolution had allowed bank to bank better. Instead, this one should allow people to bank, but without bank. That the main point of this revolution, it is disruptive. In this paper, we are going to assess potential threats that the FinTech trend could have upon traditional French Banks; How French could perceive this change, how FinTech could grow and how banks could cope.
