The legal foundations

Mandate, written into law.

Establishing legislation and the rules governing insurance may be different instruments.

02 / Market signals

The numbers, with context.

Figures retain the reporting period and accounting basis of their source. They are snapshots, not live indicators or directly comparable country rankings.

Insurance penetration. A current premium-to-GDP ratio has not been independently verified for this profile. No estimate is substituted.

03 / The report notebook

A dated view of the market.

What we noted in the regulator’s publications. Each entry separates the period covered, publication date when known, and our review date.
