Debt-for-nature swaps are financial arrangements that let a country burdened by foreign debt retire part of it at a discount, on the condition that the savings are redirected into conservation. The idea dates to 1984 and the first deal closed in 1987, but the instrument looks very different today: cumulative debt restructured through swaps since 2020 alone has reached roughly $3 billion, with some analysts estimating the potential market at up to $100 billion.1ScienceDirect. Debt-for-Nature Swaps Modern deals routinely top $300 million, involve commercial bondholders rather than friendly governments, and lock the debtor country into legally binding conservation targets for 15 to 20 years.
How a Debt-for-Nature Swap Works
Two basic structures underpin every deal.2NAP Global Network. Debt-for-Nature Swaps In a direct waiver, a creditor government forgives part of what it is owed and the debtor agrees to spend the equivalent on environmental projects at home. In a third-party purchase, a creditor sells the debt — often at a steep discount — to a nonprofit or special purpose vehicle, the debtor then repays the new holder, and the proceeds flow into conservation.
Deals since 2021 are more elaborate. A special purpose vehicle issues new bonds or loans and uses the proceeds to buy back the country’s existing commercial debt below face value. Credit enhancements, typically a guarantee or political risk insurance from the U.S. International Development Finance Corporation (DFC) or the Inter-American Development Bank (IDB), lower the interest rate on the new debt. The gap between what the country used to pay and what it pays now is the savings, and that savings is channeled into an independent conservation trust fund.3Clifford Chance. Debt-for-Nature Swaps: A New Generation The trust fund is usually governed by an independent board that mixes government, nonprofit, and expert representatives, so conservation spending does not rise and fall with political cycles.
What the Country Actually Promises
The conservation side of the deal is not aspirational. Commitments are written into the loan documents with staged milestones, deadlines, and penalties. Typical obligations include protecting a defined percentage of the country’s ocean or territory, completing a legally binding marine spatial plan, strengthening fisheries monitoring, and funding a permanent endowment.
Enforcement has sharpened in recent deals. Missing a milestone past a defined grace period can trigger financial penalties, and in some structures it constitutes an event of default on the underlying loan, with the potential to accelerate repayment and cross-default other sovereign debt.4FinDev Lab. Debt-for-Nature Swaps Policy Note El Salvador’s 2024 deal added interest rate step-ups as penalties and step-downs as rewards for compliance.5LatinFinance.

What Recent Deals Have Looked Like
The current generation of swaps began with the Seychelles in 2015–2016 and scaled up sharply after Belize’s 2021 transaction. The numbers below give a sense of how much debt is being retired, how much reaches conservation, and what the country commits to in return.
Seychelles (2015–2016)
The Seychelles bought back $21.6 million in Paris Club debt at a 5% discount, financed by a $15.2 million loan from The Nature Conservancy at 3% interest and $5 million in philanthropic grants.7SeyCCAT. Seychelles Debt Swap Case Study The deal created an independent trust (SeyCCAT) that distributes about $700,000 annually in marine and climate grants.8Frontiers in Marine Science. Seychelles Marine Spatial Planning In exchange, the country committed to protect 30% of its exclusive economic zone, over 410,000 square kilometers, with half designated as no-take zones. By 2025 marine protection had grown from 0.04% to 32.8% of the EEZ and the marine spatial plan was signed into law.9The Nature Conservancy. Seychelles Nature Bonds and Marine Spatial Planning
Belize (2021)
Belize repurchased its entire $553 million “Superbond” at 55 cents on the dollar, reducing its debt by roughly 12% of GDP.10The Nature Conservancy. TNC Belize Debt Conversion Case Study The Nature Conservancy’s Belize Blue Investment Company provided the financing, Credit Suisse packaged it into Aa2-rated blue bonds, and the DFC provided $610 million in political risk insurance.11DFC. DFC Provides $610 Million Political Risk Insurance for Innovative Debt Conversion Belize committed to protect 30% of its ocean by 2026 and to fund $180 million in conservation over 20 years, averaging $4.2 million a year, with a $23.5 million endowment projected to reach $92 million by 2041. The deal also included the first parametric catastrophe insurance for commercial sovereign debt, letting Belize defer payments after major hurricanes.
Barbados (2022)
Barbados completed a $150 million conversion using a dual-currency blue loan, with a $100 million first-loss guarantee from the IDB and a $50 million second-loss guarantee from TNC — the first deal co-guaranteed by a multilateral and a nongovernmental organization.12Inter-American Development Bank. Barbados Places Climate Financing Firmly on the Agenda The new loan carried 3.8% interest against an average 7.2% on the retired debt, freeing about $50 million for conservation over 15 years.13The Nature Conservancy. TNC Barbados Debt Conversion Case Study Barbados pledged to protect up to 30% of its EEZ, roughly 55,000 square kilometers, and gained the right to defer up to two years of principal after a natural disaster or pandemic.
Ecuador (2023)
Ecuador’s May 2023 deal was the largest conservation swap to that point. It exchanged $1.63 billion of commercial debt for a $656 million loan, roughly a 60% discount on principal, structured through an EU-based vehicle that issued Aa2-rated “Galápagos Marine Bonds.”14Pew Bertarelli Ocean Legacy. Innovative Financing Tool Helps Protect Galápagos Islands The DFC provided $656 million in political risk insurance and the IDB added an $85 million liquidity guarantee.15Inter-American Development Bank. Ecuador Completes World’s Largest Debt-Nature Conversion Over $1 billion in debt was cancelled and more than $1.1 billion in lifetime savings generated, with $323 million earmarked for a new Galápagos Life Fund that is expected to produce about $12 million a year for conservation over 18 years. Ecuador also committed to electronic monitoring on industrial fishing vessels and expanded onboard observer coverage.
Gabon (2023)
Gabon refinanced $500 million through a blue bond arranged by Bank of America, with up to $500 million in DFC political risk insurance shared across eight private reinsurers including AXA XL and Swiss Re.16DFC. DFC Political Risk Insurance to Support Blue Bond The transaction is expected to produce $163 million for ocean conservation over 15 years, with an endowment projected to reach $88 million by 2038.17The Nature Conservancy. TNC Announces Debt Conversion for Ocean Conservation in Gabon Gabon committed to protect 30% of its ocean and implement a marine spatial plan.
El Salvador (2024)
El Salvador closed a $1 billion swap in the fourth quarter of 2024, the largest conservation-focused operation to date and the first centered on freshwater. The country issued $1 billion in 20-year impact notes to a special purpose vehicle funded by a JP Morgan loan, which bought back more than $1 billion in international bonds.5LatinFinance. Sovereign Sustainable Deal of the Year The DFC provided $1 billion in political risk insurance and CAF issued $200 million in standby letters of credit. Lifetime savings are projected at $352 million, with $350 million over 20 years directed to restoring the Lempa River watershed, which covers 49% of the country.18White & Case. Debt-for-Nature Swaps: A Promising Alternative By 2044 El Salvador must designate 75,000 hectares of protected aquifer recharge zones and build a water resources monitoring system.
The Bahamas (2024)
The Bahamas completed a $300 million conversion in November 2024, backed by a $200 million IDB credit guarantee, a $70 million co-guarantee from Builders Vision, and $30 million in credit insurance from AXA XL.19The Nature Conservancy. TNC Announces Nature Bonds Project in the Bahamas It is expected to produce $124 million for conservation over 15 years, with a $20 million endowment by 2039, funding a national mangrove management plan and a marine spatial plan covering the country’s entire ocean territory.
Beyond Conservation: The Côte d’Ivoire Education Swap
In December 2024, Côte d’Ivoire completed what the World Bank called the first debt-for-development swap under a new joint World Bank-IMF approach framework. The deal directed savings toward education rather than conservation. The government bought back about €400 million in expensive commercial debt using new financing supported by a €500 million World Bank policy-based guarantee, freeing roughly €330 million over five years and generating at least €60 million in lifetime savings earmarked for schools serving 30,000 additional students.20World Bank. Côte d’Ivoire’s Debt-for-Development Swap The structure used existing government systems rather than an offshore vehicle or independent trust, with outcomes tied to a World Bank “Program for Results” instrument.21Reuters. World Bank Ventures Into Debt Swaps With Ivory Coast Education Deal The implication is that the model is being adapted for health, food security, and other goals.
The Criticisms a Reader Should Weigh
The optimistic framing around debt-for-nature swaps has drawn increasingly pointed pushback, and several concerns recur in the research.
The Debt Relief Is Small
A 2025 analysis by Debt Justice found that recent debt-for-nature swaps reduced participating countries’ debt by an average of just 3%, compared to 21% for standard debt restructurings. After accounting for mandatory conservation allocations, the net reduction in financial burden was closer to 1%. Gabon’s deal, by that analysis, actually increased the country’s debt by more than $66 million.22Debt Justice. Debt-for-Nature Swaps Reduce Debt Seven Times Less Than Debt Restructurings The IMF and World Bank have themselves cautioned that debt swaps are “generally not the right tool to address unsustainable debt situations” and should complement, not substitute for, broader restructuring. For a country in genuine distress, a swap can lock in new long-term obligations without solving the underlying problem.
Transparency and Transaction Costs
The negotiations behind these deals are consistently described as opaque. Of eight debt-for-nature swaps completed in the five years before the Debt Justice report, only four provided enough public information for independent analysis. Deals routinely take two to four years to negotiate and require expensive legal, financial, and advisory services.1ScienceDirect. Debt-for-Nature Swaps Academic research has noted the “extraordinary rent” extracted by financial intermediaries, though specific fee amounts have not been made public.
Sovereignty and Community Impact
Some scholars and civil society organizations have characterized debt-for-nature swaps as a form of “environmental colonialism,” arguing that external actors impose conservation priorities that override local governance and community needs. The Belize deal drew criticism for “sacrificing fishermen for global praise,” with fishing communities arguing that marine protection zones threatened their livelihoods without adequate consultation.
Whether the Conservation Is Really New
A persistent question is additionality: whether swap-funded conservation represents genuinely new protection or repackages commitments a government would have made anyway. Researchers have flagged the “lack of additionality in environmental protection” as a structural limitation, and have noted that swap-funded programs can be undermined by weak governance, limited institutional capacity, and corruption in the debtor country.1ScienceDirect. Debt-for-Nature Swaps
Where the Market Stands Now
The market entered a period of uncertainty after the Trump administration withdrew DFC political risk guarantees. Since the Belize, Ecuador, Gabon, and El Salvador deals all relied on DFC insurance to achieve investment-grade ratings, the withdrawal created what Reuters described as a “relative drought” in new transactions.23Reuters. UK Fund Giant L&G Commits $1 Billion to New Wave of Debt-for-Nature Swaps
Private players have moved to fill the gap. Enosis Capital, co-founded in late 2024 by former Credit Suisse specialist Ramzi Issa, entered a January 2026 partnership with AXA XL to provide political risk coverage for a $3 billion pipeline of at least a dozen deals over four years.24Reuters. Insurance Giant AXA XL, Enosis Capital Seal Debt-for-Nature Tie-Up In February 2026, UK asset manager Legal & General committed up to $1 billion over five years as a cornerstone investor in a new wave of swaps.23Reuters.

The Debt for Nature Coalition, whose members include Conservation International, The Nature Conservancy, the Pew Charitable Trusts, Re:wild, the Wildlife Conservation Society, World Wildlife Fund, and ZOMA LAB, published formal practice standards in June 2025. The standards cover conservation objectives, governance, transaction structuring, trust fund management, and monitoring and verification. They require that conservation commitments be measurable and go beyond business-as-usual, that trust funds operate at arm’s length from governments, and that projects use rights-based approaches to protect community well-being.25Blakes. Debt-for-Nature Conversion Projects: New Voluntary Practice Standards The standards are voluntary.
Several countries are at various stages of pursuing deals. The Republic of Congo has confirmed discussions with European partners for a swap linked to Congo Basin forest conservation, with no timeline set.26Ecofin Agency. Congo Plans Debt-for-Nature Swap After $670M Eurobond Sri Lanka, having completed its foreign debt restructuring in 2025, is considering debt-for-climate instruments, though a 2025 scoping study recommended treating swaps as a medium-term measure to avoid complicating the recent restructuring.27IPS Sri Lanka. Debt-for-Climate and Nature Cape Verde and Portugal completed a bilateral swap in 2023, converting $153 million of debt into an environmental and climate fund supporting renewable energy. Lao PDR has been exploring options with UNDP support since 2021, though its heavy reliance on Chinese bilateral debt (48.8% of external public debt) poses distinctive structural challenges.28UNDP. Debt-for-Nature Lao PDR
The open question is whether private credit enhancements and institutional investors can sustain the momentum that government-backed insurance built, and whether standardization through the new practice standards can close the transparency gaps that have shadowed the model since its first transaction.
