In this paper we provide an overview of the historical development of the insurance market in Sweden from the eighteenth century up to modern times. We consider theoretical perspectives drawn from the economics and political regulation literature that might help to explain important institutional features of the market - in particular, its oligopoly structure, the lack of foreign participation and the significant presence of mutual forms of organisation. We also offer a prognosis as to the current challenges and prospects of the Swedish insurance market in an increasingly competitive and global market.
