This paper discusses the world industry of savings banks, a genuine world collaborative consortium, through which, from the 1950s, the International Savings Banks Institute (nowadays, the World Savings Banks Institute and European Savings Banks Group) was highly active in introducing ICT to retail banking. In this environment, Nordic savings banks, Sweden, Norway, Finland and Denmark, their Central Savings Banks and their industry associations occupied a separate place in European movements around developments of computerization and automation in retail financial services. The synergies in Nordic countries were superior to the rest of Europe and collaboration was intense. This paper highlights the leadership and the influence that the ICT development models of Nordic savings banks had on their European retail banking associates.
