Syndicate 457 history

Syndicate 457 entered the Lloyd’s market in 1977. Amidst the backdrop of a difficult decade for the Lloyd’s market, Syndicate 457’s performance, resilience, success and agility convinced Munich Re to acquire the platform as its Lloyd’s market vehicle in 1997. Being part of Munich Re’s group brought more financial strength and capital backing for the Syndicate to further enhance its positioning and underpin its organisational growth in the years that followed.  

The growth and stability of its core market have established the Syndicate 457 as strategic within Munich Re’s overall business and led to the Syndicate being rebranded from 1st January 2016 as Munich Re Syndicate Limited.
