Recent decade saw rapid changes in retail financial services that were fueled by emergence of information technologies and new players. These changes pressure regulators, including central banks, to change the way they assess and mitigate risks, in order to ensure the integrity of the financial system but at the same time support the growth of innovations. In this paper we present the comparative overview of three new tools in the regulatory toolbox aimed at regulation of information technologies in finance: regulatory sandboxes, letters of no objection and fintech accelerators. We argue that each of these tools can be used to solve different problems and one size certainly does not fit all. As media coverage may distort perceptions about the effectiveness of certain tools, regulators need to make their information technologies-related choice based on the state of the market, available resources and the challenges they face.
