The World Bank has priced a $120 million Spekboom Restoration Outcome Bond to support large-scale ecosystem restoration and job creation in South Africa’s Eastern Cape, marking its longest-dated outcome bond to date with maturity extending to 2040.
The innovative financing structure is designed to mobilise private capital while linking investor returns to measurable environmental outcomes. The bond provides full principal protection, backed by the World Bank’s triple-A credit rating, alongside a fixed coupon and the potential for additional returns tied to project performance.
At the centre of the initiative is the restoration of spekboom, a native succulent plant known for its drought resilience and carbon sequestration capacity. The programme aims to scale restoration efforts across 50,000 hectares of degraded land, improving soil quality, water retention and biodiversity while strengthening climate resilience.
The project, developed and operated by ecosystem restoration specialist Imperative, is expected to generate around 11,000 local jobs, including opportunities for small and medium-sized enterprises involved in planting, monitoring and land management activities.
“Innovative financing is essential to address complex development challenges,” said Anshula Kant, Managing Director and World Bank Group Chief Financial Officer. “This outcome bond shows how capital markets can be mobilized to support large land restoration projects while aligning investor returns with measurable results that strengthen livelihoods and create jobs.”
Blending capital markets with environmental outcomes
Under the bond structure, investors accept a lower fixed coupon than a traditional World Bank bond, with the difference redirected—via a hedge arrangement with BNP Paribas—to provide upfront financing for the restoration project. Additional returns are linked to revenues generated from carbon removal units (CRUs), creating a direct connection between financial performance and environmental impact.
Amazon has committed to purchasing a significant share of the carbon credits generated by the project under a long-term offtake agreement. A portion of this revenue will be returned to investors as performance-linked interest.
BNP Paribas acted as sole lead manager and bookrunner on the transaction.
Frederic Zorzi, Global Head of Primary Market at BNP Paribas, said: “We are pleased to have supported the World Bank on this innovative transaction that aims to channel private capital towards measurable environmental outcomes, while maintaining principal protection and a stable income profile for investors. The structure illustrates how a collaborative approach – bringing together the World Bank, Amazon and institutional investors – can accelerate private capital mobilization while advancing the World Bank’s development objectives and provide investors with a product that aligns perfectly with their mandates and sustainability goals.”
Strong investor backing for nature-based solutions
The bond has attracted support from a range of institutional investors, reflecting growing appetite for investments that combine financial returns with measurable environmental and social impact.

Liberatore, CFA Head of ESG/Impact for Global Fixed Income at Nuveen, said: “We are thrilled to continue our partnership with the World Bank and participate in the latest Outcome Bond for spekboom restoration given its attractive relative valuation and scalable structure.

By partnering with the World Bank and BNP Paribas, the Spekboom Restoration Outcome Bond will restore degraded landscapes and support wider ecosystem recovery through carbon sequestration, while creating thousands of jobs and channelling meaningful investment into communities in South Africa’s Eastern Cape, with a strong focus on opportunities for local businesses.”
Hadiza Djataou, Vice President and Portfolio Manager at Mackenzie Investments, said: “Mackenzie Investments is proud to partner with the World Bank on the Spekboom Restoration Outcome Bond. Spekboom is a remarkable native South African succulent, recognized by the United Nations as a World Restoration Flagship for its capacity to reverse desertification and capture carbon at scale. By linking investor returns directly to the project’s carbon outcomes, this bond makes the connection between financial performance and environmental impact explicit and measurable. This is Mackenzie’s fifth investment in the World Bank’s outcome bond program, and we continue to believe that it is a structure with significant potential to scale and attract broader adoption across the industry.”

The bond will provide vital funding for a nature-based project in South Africa, focused on the large-scale planting of native Spekboom to sequester carbon, restore degraded ecosystems, and support local livelihoods. This investment reflects the continued evolution of fixed income markets in facilitating opportunities to direct capital to impactful initiatives that explicitly links financial performance to measurable real-world outcomes, alongside clearly defined risk and return profiles. Crucially, these kinds of structures enable investors to tap into high-impact areas like targeted ecosystem restoration, effectively bridging the gap between mainstream capital markets and highly specific sustainability goals.”
