International standards and best practice supports the implementation of a risk-based solvency regime in the regulation and supervision of insurers. Several emerging market and developing economies are transitioning to such a solvency regime or planning to do so. This paper discusses Kenya, Mexico, and South Africa’s journey to putting in place a risk-based solvency regime which had several common elements notwithstanding significantly different insurance sectors. The transition was a multi-year project requiring dedicated additional resources; restructuring of the regulator, including redesigning supervisory processes and tools and upgrading information technology systems; and significantly greater coordination between the regulator and the insurance industry.
