With the Brexit referendum more than 50% of the British population voted in favour of the UK leaving the EU. Since that event, much speculation has been about Brexit impact on the global economy, also affecting the insurance market. Existing papers and literature indicate potential significant Brexit implications on the structure of the European insurance market due to the loss of the European Passport, the European Solvency II supervisory regime, as well as on stock prices of insurance companies based in the EU and UK, but so far there is no holistic view on this topic. The dissertation aims to bring together the fragmentary information on Brexit implications for the European insurance market, develop methodological approaches further, conduct new analyses, and reflect a holistic picture of the impact of Brexit on the European insurance market, focusing on the structure of the European insurance market, stock market reactions and the Solvency II supervisory regime.
