Regulation of InsurTech: Is the principle of proportionality an answer?

In the view of the current discussion on how to regulate the emerging InsurTech companies, if at all, the author attempts to demonstrate that rather than automatically introducing new regulation, the principle of proportionality can, in most cases, help to adapt application of the existing rules and policy approaches to the InsurTech business models without incurring major regulatory changes. An example of peer-to-peer platforms is used to show how the specificity of each InsurTech company can be grasped by the three key criteria of proportionality: nature, scale and complexity.
