Financial Aggregation for Cities

The report defines financial aggregation as the use of instruments to combine multiple investments, projects, or participants to scale urban climate finance. It identifies key barriers to city-level investment, such as poor municipal creditworthiness and high upfront costs, and proposes supply-side aggregation (combining investor commitments) and demand-side aggregation (pooling project needs) as solutions. The document provides case studies from Africa, Asia, and South America, and emphasizes that these tools require a supportive 'enabling environment' characterized by fiscal autonomy and technical capacity.

• Cities face significant financial barriers to climate action, including poor municipal creditworthiness, weak regulatory and governance systems, foreign exchange and interest rate risks, and high upfront costs for climate-smart infrastructure.
• Supply-side aggregation combines smaller financial commitments from multiple investors or lenders to meet a specific funding need, often using structured finance tools like tranches and guarantees to attract a broader range of investor classes.
• Demand-side aggregation pools the financing needs of multiple projects or the purchasing power of multiple entities to achieve economies of scale, reduce transaction costs, and improve bankability for institutional investors.
• Blended finance is a critical supply-side tool that uses concessional public or philanthropic funds to de-risk projects, thereby mobilizing additional private commercial capital.
• Green bonds are highlighted as a highly effective tool because they can simultaneously aggregate financing from multiple institutions (supply-side) and fund multiple climate projects (demand-side).
• The success of financial aggregation depends on an 'enabling environment,' which includes fiscal decentralization, municipal autonomy over taxation, and the technical capacity to manage complex financial structures.
• Specific examples of demand-side aggregation include the Water and Sanitation Pooled Fund in India, which used a pooled bond to reduce borrowing costs for 13 urban local bodies, and the Philippines City Disaster Insurance Pool, which pools climate risks across ten cities.
• Supply-side examples include the Emerging Africa Infrastructure Fund, which reduces transaction costs by using a single fund vehicle for multiple sectors, and Climate Investor One, which uses a three-stage fund structure (development, construction, and re-financing) to match different investor risk appetites.
