Context:

• India's ambitious goal of becoming a developed nation by 2047, alongside achieving net-zero emissions by 2070, requires unprecedented investment in infrastructure.
• While the first generation of Public-Private Partnerships (PPPs) transformed sectors such as airports, highways and ports, their financing structure was fundamentally flawed.
• Instead of abandoning PPPs, India should adopt a second-generation financing architecture centred on capital circulation, enabling continuous recycling of public and private capital. 

Need for a New Infrastructure Financing Model:

• India's infrastructure pipeline had expanded to over 13,000 projects worth nearly ₹185 lakh crore by March 2025, yet this represents only a fraction of future requirements.
• Massive investments are needed in renewable energy, power transmission networks, green hydrogen, climate-resilient urban infrastructure, and adaptation and decarbonisation projects.
• Achieving net-zero by 2070 is estimated to require investments exceeding $20 trillion. Such a scale cannot be financed solely through government expenditure or corporate balance sheets.

Lessons from the First Generation of PPPs:

• The PPPs themselves did not fail; their financing model did.
• Core problem - Asset-liability mismatch: Infrastructure assets typically generate returns over 30–50 years, but many PPP projects were financed through bank loans with repayment periods of only 7–10 years.
• Consequently:
  • Debt servicing peaked during the early years when revenues were uncertain.
  • Following the Global Financial Crisis (2008) and domestic economic slowdown, project revenues declined while debt obligations remained fixed.
  • This led to rising Non-Performing Assets (NPAs), stressed infrastructure projects and declining investor confidence.
• Key takeaway: Long-term infrastructure was financed using short-term capital, creating systemic financial stress.

From Capital Scarcity to Capital Circulation:

• India's challenge today is not merely raising more capital but efficiently matching different sources of capital with different stages of project risk.
• Risk-based financing across the project lifecycle:
  • Different investors should finance projects according to their risk appetite.
  • Project stage (Appropriate investor):
    • Project preparation, land acquisition, construction (Government/public sector).
    • Operational and revenue-generating stage [Developers and Infrastructure Investment Trusts (InvITs)].
    • Mature, low-risk assets (Pension funds, insurance companies, sovereign wealth funds).
  • This ensures that public capital is recycled instead of remaining locked in completed projects.

India's Existing Institutional Strengths:

• India has already developed important financing platforms, like,
  • Infrastructure Investment Trusts (InvITs): Enable monetisation of operational infrastructure assets.
  • National Investment and Infrastructure Fund (NIIF): Has successfully attracted global institutional investors.
• However, these mechanisms need to function within a continuous capital recycling framework, where ownership and financing shift as project risks decline.

The Concept of Circular Finance with Continuous Capital Recycling:

• Working:
  • Government and developers finance project construction.
  • Once projects become operational and revenues stabilise, InvITs acquire these assets.
  • Governments and developers recover capital and reinvest it in new infrastructure.
  • Operational projects are refinanced through Infrastructure Debt Funds (IDFs).
  • Eventually, mature assets are financed by pension funds, insurance companies and sovereign wealth funds, which seek stable long-term returns.
• Implication: This reduces financing costs while ensuring capital remains available for successive infrastructure projects.

Role of Financial Sector Reforms:

• Dynamic risk-based loan repricing:
  • The Reserve Bank of India (RBI) must mandate dynamic risk-based repricing of infrastructure loans.
  • Currently, banks continue charging interest rates based on construction-stage risks even after projects become operational. This discourages refinancing and delays capital recycling.
  • Risk-based repricing would lower borrowing costs for de-risked projects and facilitate transfer of assets to long-term investors.
• Reviving infrastructure debt funds: Infrastructure Debt Funds should serve as intermediaries between operational infrastructure assets and institutional investors by -
  • Refinancing expensive bank loans.
  • Providing long-term, lower-cost capital.
  • Improving overall financial sustainability of infrastructure projects.

Why Capital Circulation Matters?

• Keeping public funds or bank capital locked indefinitely in mature infrastructure reduces the economy's capacity to finance new projects.
• A robust capital circulation framework would:
  • Improve efficiency in infrastructure financing.
  • Reduce pressure on public finances.
  • Lower the cost of capital.
  • Attract global long-term institutional investors.
  • Support sustainable infrastructure expansion while maintaining fiscal discipline.

Conclusion:

• India's infrastructure ambitions demand a shift from merely mobilising private capital to creating a financing ecosystem where capital circulation is as important as capital mobilisation in achieving the Viksit Bharat 2047 vision.
• Therefore, the second generation of PPPs must focus on risk-appropriate financing, refinancing, asset recycling and institutional participation.
