Microinsurance has emerged as a pivotal instrument in India's financial inclusion landscape, offering affordable protection to vulnerable populations such as low-income rural households, women, small farmers, and landless laborers who face high risks from health shocks, crop failures, and natural disasters. The sector has witnessed robust growth, with the market reaching USD 428.4 million in 2024 and projected to expand to USD 1,693.3 million by 2033 at a CAGR of 15.67%, driven by government initiatives like Pradhan Mantri Jan Dhan Yojana (PMJDY) and Pradhan Mantri Suraksha Bima Yojana, alongside technological innovations in digital distribution and mobile claims processing. New business premiums in life microinsurance surpassed USD 1.12 billion in FY2023-24, marking a 23.5% year-on-year increase, reflecting heightened penetration among the underserved.

This paper examines the evolution of microinsurance in India, highlighting its role in mitigating vulnerability, fostering savings, enabling credit access, and promoting social equity for marginalized groups. By reducing debt traps from unforeseen events, microinsurance complements broader financial inclusion efforts, with over 66% of PMJDY accounts now linked to accident insurance coverage. Despite achievements, challenges persist, including low awareness, affordability barriers, and distribution gaps in rural areas, necessitating enhanced financial literacy campaigns, innovative premium models, and regulatory incentives.

Leveraging data from IRDAI reports and market analyses, the study underscores informatics-driven strategies such as AI-enabled risk assessment and blockchain for claims transparency as key to scaling impact. Microinsurance not only shields vulnerable populations from poverty but also aligns with sustainable development goals, positioning India as a global model for inclusive finance. Policymakers and insurers must prioritize trust-building through quick settlements and targeted outreach to sustain this trajectory.
