Johannesburg, 1 April 2026 — FirstRand Bank (FRB) has become the first commercial bank globally to issue an outcomes-based bond that directly links investor returns to verified ecological and environmental restoration outcomes.
The bond forms part of a broader transaction structure which raised funding from outcomes-based funders (OBFs) for a nature conservation project to remove invasive alien plant species from priority water catchment areas in the Western Cape to increase water flow into storage dams through water reclamation.
RMB acted as arranger, structurer and distributor for the R2.5 billion JSE-listed Cape water performance-based bond issuance. The bond was anchored by the International Finance Corporation (IFC) and FSD Africa Investments (FSDAi), a specialist financial sector investor established by FSD Africa and the UK’s Foreign Commonwealth and Development OƯice (FCDO). Their participation was instrumental in validating the transaction structure and catalysing broader institutional investor participation. The IFC subscribed for approximately R1.6 billion whilst FSDAi committed R234 million.
Aluwani Capital Partners led local institutional participation with a R350 million investment in the bond, with further support from Ashburton Investments, the Eskom Pension and Provident Fund, Optimum Investment Group and Sanlam Life.
The bond establishes a new asset class for nature-linked adaptation finance, whereby investor returns are contingent on the delivery of pre-defined and verified nature positive outcomes that are embedded directly into a listed senior unsecured bond structure. The transaction shares the risk of funding conservation activities between OBFs and bond investors who receive enhanced returns if pre-defined conservation outcomes are met. This enables a pay-for-success model for OBFs, based on measurable and independently verified outcomes. It presents a scalable, rigorous and transparent template for mobilising private capital and can be replicated for wider environmental, social or development projects in South Africa and elsewhere.
The group’s corporate and investment bank, RMB, was instrumental in the structuring and execution of this transaction, and the FirstRand Foundation also played a key role as an anchor outcomes-based funder and coordinator for other philanthropic partners.
Kalina B. Miller, IFC Financial Institutions Group Regional Manager for Southern Africa, said:
IFC is proud to be the lead investor in this ground-breaking and innovative transaction, which leverages the capital markets to enable and crowd in private sector capital toward conservation activities. The instrument links investor returns to measurable environmental outcomes in South Africa’s strategic water catchment areas and sets a replicable blueprint for nature finance across Africa and globally. The pay-for-success financial structure would help address water security in South Africa – a key development challenge in the country – and create jobs, including for women and youth.
Anne-Marie Chidzero, Chief Investment Officer at FSDAi, said:
“Nature has long been treated as a cost; this bond demonstrates it can be structured as an asset. What makes the Cape water performance-based bond significant is not just what it finances, but who it brings together —and FSDAi is proud to stand alongside partners united by the conviction that Africa’s markets are ready to price nature differently. That collective commitment turns reclaimed water into a verifiable, investable outcome and opens the door to an entirely new asset class in Africa’s capital markets.
Antony Phillipson, British High Commissioner to South Africa, said:
Nature is critical infrastructure, and linking investment returns to verified environmental improvements shows how finance can drive real resilience. This bond demonstrates what is possible when partners unite behind a shared commitment to protect ecosystems and strengthen water security. It also reflects the deepening collaboration between the UK and South Africa to scale sustainable finance and unlock new opportunities for nature-positive growth.
Monica Jaglal, Co-Head of Credit at Aluwani Capital Partners, said:
Water is an increasingly scarce and mispriced resource. Our investment in the Cape water performance-based bond reflects a deliberate commitment to investing in water—not only in infrastructure such as pipes and dams, but in the ecosystems that sustain supply. By unlocking additional water yield at a fraction of the cost of traditional infrastructure, we are delivering measurable environmental and social impact, in line with our responsibility as stewards of capital.
