Longevity finance is emerging to address the financial challenges of extended lifespans and aging populations. Financial institutions lag in adapting to longevity risk, retirement planning, and wealth management innovations. Key trends include AI-driven financial planning, Insurtech solutions, and longevity-focused investment funds. Global collaboration is essential, with Japan and Switzerland offering best practices. Policies must reposition aging populations as economic contributors, leveraging longevity bonds, ESG investing, and lifelong learning initiatives. A sustainable longevity economy requires inclusive financial models and regulatory harmonization to ensure long-term stability.
