Five countries show how. * **$225m**World Bank outcome bond linked to Amazon reforestation, August 2024 * **160%**of its learning target reached by India’s Educate Girls impact bond * **$300m**IDB guarantee behind Ecuador’s US$400 million social bond, 2020 * **$2bn**Chile’s 20-year sustainability-linked bond, the first by a sovereign, 2022 A nation’s future is built through decisions about schools, homes, energy, ecosystems and the institutions that sustain them. Financing those decisions takes more than a larger pool of money. It takes a clear agreement on who supplies the capital, who repays it, who carries the risk and what the public receives. Five country examples show five ways to write that agreement. Some link returns to verified outcomes. Others earmark borrowing for a social purpose, attach targets to the terms of debt, or open government securities to small savers. Each structure solves a different financing problem. #### Five instruments at a glance | Country | Instrument | How it works | What is measured | | Brazil | Outcome bond | Part of the investor return depends on carbon removal. | Reforestation and verified carbon removal | | India | Development impact bond | An outcome payer repays upfront capital against results. | School enrolment and learning | | Ecuador | Social bond with a guarantee | Proceeds finance eligible social mortgages. | Use of funds and housing outcomes | | Chile | Sustainability-linked bond | Debt terms change if targets are missed. | Emissions and renewable electricity | | Kenya | Mobile retail government bond | Citizens buy sovereign debt by phone. | Participation and access | These are past transactions, presented as design precedents. The Brazil example was issued by the World Bank and the India example by a partnership financing an education programme; neither was a sovereign bond of those countries. #### 1. Brazil: an outcome bond that ties returns to reforestation In August 2024 the World Bank priced a nine-year, US$225 million Amazon Reforestation- Linked Bond. Its coupon combines a guaranteed component with one linked to Carbon Removal Units generated by reforestation projects in Brazil. Investors give up part of the ordinary coupon; a hedge mobilises about US$36 million for Mombak’s reforestation work, and revenue from carbon-removal sales supports the variable return. Principal is protected at maturity. US$225 million is the face value; about US$36 million reaches the forest. **What is measured:** independently verified carbon removal. [See the Brazil blueprint](https://perfectnations.org/blueprints/brazil/). #### 2. India: a development impact bond that pays for learning The Educate Girls Development Impact Bond financed a three-year education programme in Rajasthan, with final results announced in 2018. UBS Optimus Foundation supplied US$270,000 of upfront capital, Educate Girls delivered the programme, and the Children’s Investment Fund Foundation repaid the investor against verified results. The programme reached 116 per cent of its enrolment target and 160 per cent of its learning target. **What is measured:** enrolment and learning. The lesson for a nation is the separation of the party that finances delivery from the party that pays for success. [See the India blueprint](https://perfectnations.org/blueprints/india/). #### 3. Ecuador: a social bond backed by a partial guarantee In 2020 Ecuador issued a US$400 million, 15-year sovereign social bond for affordable housing, supported by a US$300 million guarantee from the Inter-American Development Bank. Proceeds finance eligible social mortgages under the Casa para Todos programme. Ecuador remains the borrower; the guarantee covers specified payment obligations, not the whole bond. **What is measured:** the use of funds and social impact, reported each year. The bond directs borrowing to a purpose; its coupon does not pay per home delivered. #### 4. Chile: a sustainability-linked bond that changes the cost of debt In March 2022 Chile issued a US$2 billion, 20-year sustainability-linked bond, the first by a sovereign. Its framework sets indicators for greenhouse-gas emissions and the share of non-conventional renewable electricity. Missing a specified target carries a financial consequence under the bond’s terms. **What is measured:** performance against the indicators on fixed observation dates. Unlike a green or social bond, the commitment sits in the terms of the debt, not in the use of proceeds. #### 5. Kenya: a mobile government bond that broadens access Kenya’s M-Akiba, launched in 2017, let retail investors buy a three-year government bond by phone from KSh 3,000, at a 10 per cent coupon paid twice a year. The main launch raised less than a quarter of the KSh 1 billion offered, yet 85 per cent of buyers surveyed had never bought a bond before. Digital access needs clear instructions, support and a product suited to savers. **What is measured:** participation and access. M-Akiba was a mobile-distributed bond, not a token; it informs the access ambition behind the proposed Standard Tokens.

A school programme with a committed outcome payer is a different financing problem from a mortgage programme, a reforestation project or an energy transition. Five questions come first: what must improve, who can credibly pay, which risks each party can manage, what evidence will verify delivery, and whether the financing stays affordable through a shock. An outcome bond needs credible measurement and an outcome-linked revenue. An impact bond needs an outcome payer. A social bond needs eligible spending and reporting. A sustainability-linked bond needs meaningful targets and enforceable terms. A retail bond needs access, plain risks and dependable service.
