The acceleration of infrastructure development across India, now exceeding 3% of the nation's gross domestic product, is occurring disproportionately in climate-vulnerable regions, a new report reveals. This expansion is happening even as insurers grapple with accurately pricing escalating and increasingly predictable climate-related perils.
Escalating Climate Perils Blunt Infrastructure Growth
Climate impacts in India are no longer sporadic events but are rising steadily in frequency and severity, with a sharp acceleration noted since the mid-2010s. Hydro-meteorological disasters, particularly floods, now dominate the risk landscape. An analysis of Delhi shows that while urban areas expanded at about 1.3% annually between 1986 and 2016, flood exposure grew at a faster rate of around 2.46%. This divergence is expected to widen, increasing asset concentration in at-risk zones. States like Assam, Andhra Pradesh, Odisha, Uttarakhand, Himachal Pradesh, Sikkim, Ladakh, and parts of the Northeast are identified as highly vulnerable, yet they are also hubs for substantial infrastructure investment, with an estimated ₹2.95 trillion exposed across ports, tunnels, highways, and hydropower projects.
Insurers Grapple with Pricing Pains
Interviews with insurers and reinsurers, including SBI General Insurance, Munich Re India, Swiss Re India, and the General Insurance Corporation of India, indicate mounting stress in climate risk pricing. Two-thirds of surveyed insurers reported rising premiums since 2015. All respondents flagged affordability challenges for infrastructure projects, especially hydropower assets situated in flood and landslide-prone terrain. Insurers warned that the uncertainty surrounding future climate impacts makes underwriting increasingly complex. This complexity could potentially discourage coverage or shift risks back onto project developers and the state.
Regulatory Tightrope and Fiscal Exposure
The findings present a significant challenge for the Insurance Regulatory and Development Authority of India (IRDAI), which is tasked with promoting deeper insurance penetration while managing emerging risks like climate change. India's non-life insurance penetration remains low, around 1%, far below global averages, even as climate-linked losses mount. Without standardized frameworks for climate risk disclosure, modeling, underwriting, premium pricing, and loss assessment, insurers may struggle to maintain solvency while keeping infrastructure insurance affordable. While parametric products are emerging, coverage gaps persist for high-impact risks such as cloudbursts and landslides. For the finance ministry, the report raises concerns about rising contingent liabilities, as uninsured or under-insured losses may be absorbed through disaster relief and public funding. Continued infrastructure build-out in high-risk regions without embedding climate resilience from the design stage could elevate fiscal exposure, particularly given the involvement of public sector banks and state-owned insurers. Globally, insured property losses exceeded $140 billion in FY25, while India's natural catastrophe losses in 2023 reached $12 billion, underscoring the potential spillover into public finances. Aarti Khosla, founder and director of Climate Trends, stressed that "climate resilience must be integrated into infrastructure planning from the very beginning to minimize the costs of post-disaster reconstruction." Long-term insurance viability will also depend on advanced actuarial models and standardized risk frameworks.
