Instrument Overview
Project-level market-rate debt refers to commercial lending raised for a specific infrastructure or development project, structured to reflect true market interest rates (unsubsidized), and typically secured solely by that project's assets and cash flows, rather than by a city’s general credit or tax base. This model is a key feature of project finance.
Why it matters for cities
- Enables large public projects (e.g. renewable energy, transport, utilities) to be financed off-balance sheet, mitigating impacts on municipal borrowing caps and credit.
- Attracts private lenders or institutional investors, increasing access to private capital.
- Aligns repayment with project revenue streams, reducing reliance on general taxation.
This tool is valuable especially for cities with predictable, project-generated income, such as user fees or long-term offtake contracts
Key Features
- Non-recourse or limited-recourse structure: Lenders rely on project cash flows; the municipality’s wider balance sheet is generally insulated
- Market-rate interest: Interest rates reflect commercial risk and funding conditions – not subsidized public loan rates
- Debt sizing via cash flow modelling: Debt amount is calibrated around metric like DSCR (Debt Service Coverage Ratio), LLCR, PLCR to ensure serviceability from projected revenues
- Multiple participants: Project-level debt may be syndicated among banks or issued via project bonds, often requiring intercreditor agreements and SPV setups
How it works
- Project SPV formation: A special-purpose vehicle (SPV) is created to own and manage the project, isolating risks from municipal finances.
- Revenue structure setup: Secured off-take agreements (e.g., with utility customers), user fees, or service contracts from the predictable cash flow base
- Financial modelling and debt sizing: Lenders assess DSCR, LLCR, PLCR to determine sustainable loan size and interest margin
- Loan issuance or bond offering: Market-rate debt may be syndicated or issued as project bonds, often with credit enhancements (guarantees, reserve accounts).
- Security package: Lenders are granted liens on project contracts, assets, and cash flow streams.
- Servicing and monitoring: Debt service is paid from project revenues; lenders monitor compliance and performance. If project underperforms, lenders may enforce remedies—a risk absorbed by the SPV, not the municipality at large.
Benefits & Challenges for Cities
Benefits
- Off-balance sheet financing protects multiple metrics
- Market-level pricing can be competitive if the project revenue profile is reliable
- Scalability and efficiency for capital-intensive projects
- Encourages private capital participation and risk-sharing
Challenges
- requires robust, predictable cash flows – not suited to projects with uncertain revenues
- complex structuring, legal, and financial documentation (SPV, security, modelling)
- potentially higher overall cost versus subsidized loans or pooled municipal funding agencies.
- less flexibility after close – covenant compliance and limited recourse commitments are binding.
Use Case
In June 2025, the Pimpri-Chinchwad Municipal Corporation (PCMC) in Maharashtra, India, issued ₹200 crore (approx. USD 24 million) in green municipal bonds - making it the first civic body in the state to access capital markets for sustainable infrastructure through this mechanism. The funds are earmarked for the ‘Harit Setu’ initiative, part of the city’s long-term sustainable mobility master plan, which prioritizes green urban corridors and non-motorized transport infrastructure such as the Telco Road project in Nigdi Pradhikaran. The bonds carry a 5-year maturity and a 7.85% coupon rate, reflecting market-level financing terms rather than concessional support.
The bond issue was a success - oversubscribed by more than five, highlighting investor confidence in urban green infrastructure backed by municipal credibility. By directly linking proceeds to climate-smart mobility infrastructure, PCMC’s bond issue is a strong example of how cities can utilize project finance instruments at commercial rates to deliver measurable environmental benefits while attracting mainstream investment capital.
When to use it
- When the project is self-sustaining, with clear revenue sources like tariffs or long-term contracts.
- When the municipality wants to limit impact on overall borrowing limits or credit rating.
- If private sector involvement is required to offload construction, operational, or demand risk.
- If public grant or subsidized sources aren’t available, or if commercial participation offers more scale or expertise.
