Indian civic bodies could raise around Rs 10,000 crore through green municipal bonds over FY27-FY30 as cities look for additional sources of capital to finance water, waste, renewable energy and climate-resilient infrastructure, according to ICRA.
Urban infrastructure investment requirements are estimated at more than Rs 56 lakh crore during the period, of which up to Rs 3 lakh crore could be financed through commercial debt. Municipal and green bonds could form part of this funding requirement.
Projects covering water supply, sewerage and wastewater treatment, solid waste management, renewable energy and climate-resilient infrastructure can qualify for green financing, providing municipalities with a sizeable pipeline of potential projects.
Around a fourth of the Rs 6,540 crore raised through municipal bonds so far qualifies as green municipal bonds, while another 25 per cent potentially meets the criteria to be classified as green.
Investor Appetite Builds For Green Municipal Debt
ICRA estimates a base-case green municipal bond issuance potential of Rs 10,000 crore between FY27 and FY30, with scope for further growth as more urban local bodies become ready to access capital markets.
Recent green municipal bond issues have attracted subscriptions of around five times the amount offered, indicating growing investor demand. Such issuances have also provided a yield premium of up to 1.90 percentage points over sovereign benchmarks and up to 1.55 percentage points over comparable state benchmarks.
However, the ability of municipalities to bring suitable issuances to the market remains a key constraint. Civic bodies require adequate credit quality, financial disclosures, visibility over repayment, prepared projects and transaction readiness before they can sustainably raise funds from capital markets.
These requirements could substantially narrow the number of municipalities capable of issuing bonds despite India's much larger urban infrastructure financing requirement.
Policy support and market-development measures are gradually addressing some of these barriers. As more municipalities improve their financial and project preparedness, green bonds could become a larger financing channel for India's urban water, waste, renewable-energy and climate-resilience infrastructure.
