Trends & Challenges in the Insurance Industry

Regulatory & Capital Requirements: Solvency standards, reserve requirements, amid low interest rates, can squeeze profitability.
Interest Rate Environment: Low interest rates make it harder for life insurers and those with long-term liabilities to earn sufficient returns. Changing interest rates affect investment income.
Technological / Digital Disruption: Insurtech startups, data analytics, AI, IoT (e.g. telematics, sensors) are changing how risk is assessed, pricing, claims.
Demographic Shifts: Aging populations in many developed countries change demand (e.g. more life/health claims, pension liabilities).
