Starr International Insurance (Switzerland) AG (“SIIS” or “the Company”) was incorporated on 23 November 2020 in Switzerland, having registration number CHE-157.870.447, and was authorised to conduct insurance and reinsurance business in December 2020, commencing effective underwriting activities on 1 April 2021.
The Company’s material lines of business during 2025 were Aviation, Property (previously referred to as Tech/Construction), Marine, Casualty and Financial Lines, operating mainly in Switzerland and the European Economic Area. The development of SIISAG’s business had been based on the strategy of generating new business within the EEA and for renewing EEA risks inherited from affiliated insurers, mainly Starr Insurance (Europe) Limited (“SIEL”), a group company in the United Kingdom, and Starr Europe Insurance Limited (“SEIL”), a group company in Malta (EU). In addition to the base that the renewal business provides, SIISAG also aims to utilise the Starr Group’s established market presence and relationships with established brokers, to attract new opportunities for the Company within Switzerland, specifically, and the EEA.
