Risk Gaps: First-Loss Protection Mechanisms

The report examines first-loss protection mechanisms as tools to bridge the financing gap for low-carbon infrastructure by shielding institutional investors from initial losses. It analyzes two primary models: the European Commission-European Investment Bank Project Bond Initiative (EC-EIB PBI) and the proposed Sustainable Development Bond Assurance Corporation (SDBAC). The authors argue that for these instruments to be effective, they must align with investors' risk-return profiles, secure investment-grade ratings from agencies, and be priced competitively, often requiring concessional support from sponsors like development banks to remain viable.

• First-loss protection mechanisms aim to attract institutional investors by shielding them from a pre-defined amount of financial loss, thereby improving the credit profile of low-carbon investments and freeing up bank balance sheets.
• The EC-EIB Project Bond Initiative (PBI) uses a guarantee facility—either as a funded subordinated debt tranche or a contingent credit line—to raise the credit rating of individual infrastructure projects to investment grade (typically A- or higher).
• The proposed Sustainable Development Bond Assurance Corporation (SDBAC) would use a monoline entity to provide first-loss insurance for collateralized loan obligations (CLOs) of green projects, including insuring power purchase agreements (PPAs) against government policy reversals or off-taker defaults.
• Credit rating agencies heavily favor full financial guarantees over mechanisms that mitigate specific risks, which can exclude climate investments because full guarantees are often too expensive for most institutions to provide.
• The cost of credit enhancement for clean investments has risen significantly; while approximately 7% was required for a AAA rating before 2007, it was over 25% by 2011, making such transactions likely non-earnings-accretive for banks.
• Commercial-basis risk guarantees for renewable energy can be too expensive to attract buyers without grant funding, as evidenced by the ADB India Solar Power Generation Guarantee Facility, which only became competitive after a UK DECC grant halved the fees.
• First-loss mechanisms can induce moral hazard by attracting low-quality projects or encouraging riskier behavior since the protection provider bears the negative effects.
