The insurance industry is a solid cornerstone of the financial system, and by fostering an environment more favorable to investment, it significantly boosts economic growth. This is especially true for the Western Balkan countries, which are currently growing and joining the European Union. Developing countries can benefit from an additional avenue: the internationalization of insurance businesses through the reinsurance process. The aim of this research is to assess the potential impact of Foreign Direct Investment (FDI) on the insurance industry in the region. The research was carried out in six countries: Albania, Bosnia and Herzegovina, Montenegro, North Macedonia, Kosovo, and Serbia. Data from these countries were collected between 2004 and 2021, allowing for an analysis using panel data econometric models, namely the Fixed Effects and Random-Effects models (GLS). The findings of the economic analysis for the three independent variables indicate that FDI inflow positively affects Gross Written Premium (GWP), Insurance Assets (InsAsset), and Penetration Rate (PenetRate) at the α=0.05 significance level. Additionally, the models have demonstrated that the three variables have variations between the countries regarding the impact of FDI inflows using the Lagrange Multiplier (LM) Method -Breusch-Pagan test, at a confidence level of α=0.05. Since the econometric models for the three cases are based on the Random-Effects model (GLS Method), random effects are to blame for the variations in FDI influence between countries. The results have consequences for the insurance industry as well as regional policymakers, especially in Kosovo, who are deciding what measures to take to promote foreign direct investment.
