Municipal Bonds Model Under union finance ministry guidelines, urban local bodies can issue bonds for well-prepared, "ring-fenced" projects that can assure investors of returns. Investors—typically insurers, banks, and private companies—fund these projects at agreed-upon interest rates, with repayment handled by the local body. GCC’s decision is driven by its annual revenue of Rs.4,500 crore, most of which is allocated to administrative expenses and salaries, leaving little for development projects.

Previous Success with Bonds Other cities in India, including Pune and Hyderabad, have successfully used this model to raise substantial funds for infrastructure. For instance, Pune Municipal Corporation raised Rs.2,264 crore through bonds for a 24/7 water supply project in 2017, paying back the bonds semi-annually at an interest rate of 7.5%. Hyderabad utilized Rs.600 crore from bond sales for road development. Chennai hopes to replicate this success to fund crucial infrastructure growth.

Challenges with Bond Repayments Despite the potential benefits, some experts, like D S Sivasamy, have expressed concerns about repayment. Corporations often struggle to repay high-interest bonds due to limited revenue streams, primarily relying on property taxes and state grants. Sivasamy suggests increasing collections of entertainment and professional taxes to ensure GCC can meet its repayment obligations and avoid financial strain.

With rapid urban growth and limited funding sources, municipal bonds could be a sustainable way for Chennai to address its infrastructure needs while learning from other cities’ successes and challenges.
