Solertia Capital Advisors

Authorised and regulated by the Financial Conduct Authority



Solertia Capital Advisors provides advice and structuring services to financial institutions, located in Europe and North America, targeted at reducing capital costs, optimising balance sheet use and improving return on capital.  

Many financial institutions do not possess all of the necessary capabilities to develop, structure and implement such transaction based solutions, and therefore benefit from Solertia Capital Advisor's provision of a “cradle-to-grave” transaction structuring and execution service.  


The Solertia Capital team is a turnkey multi-disciplinary team of professionals, blending insurance and banking regulation, accounting, US & non-US tax, and capital markets skills, with extensive experience in the global insurance and banking sectors, offering innovative solutions and proven execution which is capable of delivering substantial RoE improvements for its clients.


The team, individually and collectively, have an impressive history of profitable, value added transactions. They have developed a market-leading reputation for innovative, commercially driven transactions within the sector.

The core team members have worked together for over a decade, during which they have collectively delivered over one billion USD of economic value for their respective employers during that period, through  the design and implementation of numerous transactions involving a broad range of technologies and asset classes (securitisations, structured trusts, structured notes and securities lending transactions).
