The International Finance Corporation (IFC), FSD Africa Investments (FSDAi) and Aluwani Capital Partners anchored the Cape Water Performance-Based Bond by buying its notes early and in size, about R2.18 billion of the R2.5 billion issue between them, and none of them pays for outcomes.
Overview
In April 2026 FirstRand Bank issued the Cape Water Performance-Based Bond (JSE code FR31PB), a R2.5 billion listed note arranged by Rand Merchant Bank (RMB). Part of what noteholders earn depends on independently verified clearing of invasive alien plants in the catchments that supply Cape Town’s dams. It is the first performance-based bond issued by a commercial bank in which investor returns are tied to verified ecological restoration. The general mechanism is set out in Performance-Based Water Bonds.
Three investors carried the book. IFC bought about R1.6 billion, Aluwani R350 million and FSDAi R234 million. All three sit in the noteholder layer. The success premium is paid by a separate group of outcome funders led by the FirstRand Foundation. In this deal, “co-anchor investor” therefore means an early, large buyer of notes whose commitment made the issue viable. It carries no obligation to pay for outcomes in any primary source.
Their stated reasons differ, and each tracks the investor’s mandate. IFC speaks of creating a first-of-its-kind market and a template for nature finance. FSDAi speaks of proving the structure and pulling South African asset managers and pension funds in behind it. Aluwani, a South African asset manager investing its clients’ money, frames water as a scarce resource that capital markets misprice. FirstRand’s own account is more direct: IFC’s investment “was essential to achieve the target bond size”, and Aluwani’s early commitment helped complete the book build.
This brief also records where the public sources disagree: on Aluwani’s exact label, on what happens to noteholders if targets are missed, and on where the bond’s principal goes. Several deal terms, including the coupon and the size of the success premium, are not public.
How evidence is labeled
“Own statement” means the organization speaking about itself, through its website, filings, reports or a named spokesperson. “Deal-party statement” means another party to the transaction speaking: FirstRand or RMB, the JSE, The Nature Conservancy, the Western Cape Government, or FSD Africa when it describes other investors. “Independent reporting” means media and aggregators. “Inference” marks reasoning drawn from the sources that no source states.
The bond has two layers: noteholders and outcome funders
The public sources describe two layers of capital and no tranching.
The first is a single listed senior unsecured note of R2.5 billion, issued by FirstRand Bank and listed on the JSE on 17 April 2026, with RMB as arranger and structurer (deal-party statement, JSE). FSD Africa describes it as embedding “conservation outcomes directly into a conventional fixed income security” (FSD Africa, “Behind the investment”). TimesLive reports that it was issued under RMB’s domestic medium-term note program (independent reporting). No source describes a subordinated or first-loss slice. The Nature Conservancy (TNC) assigns the roles: FirstRand Bank is “issuer, project agent, and conditional funding donor”; RMB is “arranger, structurer, and distributor”; Conservation Alpha is the “independent design and technical agent” overseeing verification; TNC South Africa does the restoration through the Greater Cape Town Water Fund (deal-party statement, TNC).
The second layer is the outcomes-based funders. The JSE names the FirstRand Foundation as “anchor outcomes-based funder” and coordinator of the other philanthropic partners. Only two outcome-funder amounts are public, both from independent reporting: the FirstRand Foundation at R50 million over five years and the Development Bank of Southern Africa (DBSA) at R50 million, approved as a grant through its Green Fund. Remgro, the Rupert Nature Foundation and the Lewis Foundation are also named.
In FSD Africa’s account, noteholders receive “a base return plus a success premium” tied to verified outcomes. Outcome funders “underwrite the success premium” and “only pay when results are achieved”; if outcomes are missed, their capital is returned for redeployment. The only payment metric named publicly is hectares of invasive alien plants cleared from priority catchments. On the conservation side, TNC says TNC South Africa “will receive R150M (about USD $8.8M) in conservation funding, in the form of donations and related catalytic funding” over five years, and the Western Cape Government says most of the project’s funds came from outcome-funder contributions (deal-party statements).
| Layer | Party | Role | Disclosed amount | Source type |
|---|---|---|---|---|
| Noteholder | International Finance Corporation | Lead investor, co-anchor | About R1.6 billion (“up to ZAR1.6 billion”) | Own statement (IFC disclosure) |
| Noteholder | Aluwani Capital Partners | Co-anchor (JSE) or leader of local participation (FSD Africa) | R350 million | Deal-party statement (FSD Africa) |
| Noteholder | FSD Africa Investments | Co-anchor | R234 million | Own statement (FSD Africa) |
| Noteholder | Ashburton Investments, Eskom Pension and Provident Fund, Optimum Investment Group, Sanlam Life | Participants | Not disclosed | Deal-party statement (FSD Africa) |
| Outcome funder | FirstRand Foundation | Anchor outcome funder, coordinator | R50 million over five years | Independent reporting (ESG News) |
| Outcome funder | DBSA (Green Fund) | Outcome funder | R50 million grant | Independent reporting (TimesLive) |
| Outcome funder | Remgro, Rupert Nature Foundation, Lewis Foundation | Outcome funders | Not disclosed | Independent reporting (ESG News) |
Inference: the three co-anchor tickets total about R2.18 billion, roughly 87% of the issue, leaving about R316 million for the four other named noteholders and any unnamed buyers. This assumes the full R2.5 billion was placed and uses IFC’s approximate figure.
The base coupon, the size of the premium, the hectare targets, the frequency of verification and the maturity date are not in any source found. No public pricing supplement or listing notice for FR31PB was located.
IFC: about R1.6 billion so the issue could reach its size
What IFC is
IFC is the private-sector arm of the World Bank Group. It describes itself as “Owned by 186 member countries and consistently rated AAA/Aaa”, with a mission of “promoting development by providing debt and equity to the private sector”, record commitments of $71.7 billion in its 2025 financial year, and operations in more than 100 countries (own statement). The deal was handled by its Financial Institutions Group for Africa.
What it bought
IFC’s project disclosure, number 52393, describes “an up to ZAR1.6 billion IFC anchor investment in a senior unsecured outcome-based bond” within a target issue of R2.5 billion, shown as an indicative US$100.57 million and booked as a senior loan. It was approved on 20 March 2026, signed on 23 March, invested on 31 March and disclosed on 1 April (own statement). The investors’ joint release says “The IFC subscribed for approximately R1.6 billion”, and Reuters-based reporting says IFC “subscribed for 1.6 billion rand of the bond”. No source shows IFC using a blended-finance window or donor trust fund, and none places it among the outcome funders. Inference: at about 64% of the issue, IFC’s ticket was most of the bond.
Why it says it invested
IFC’s Financial Institutions Group Regional Manager for Southern Africa set out its reasons in the joint release (own statement):
- On building the market: “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.”
- On replication: “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.”
- On development outcomes: the structure “would help address water security in South Africa”, which she called “a key development challenge in the country”, “and create jobs, including for women and youth.”
IFC’s disclosure adds its case for being needed: “IFC will anchor the first outcome-based bond issued by a commercial bank globally.” It says the structure creates a new asset class for nature-linked adaptation finance, that its participation should attract other investors, and that its investment is essential to reach the target size. Its development-impact note opens: “Water security in South Africa depends heavily on a limited number of strategic catchment areas”, and expects reduced water stress, more reliable supply for Cape Town, and lower drought and wildfire risk (own statement). FirstRand’s Group Treasurer confirms the size point from the issuer’s side: “The IFC’s investment was essential to achieve the target bond size, enabling the overall transaction” (deal-party statement, JSE).
How it fits IFC’s wider work
IFC’s biodiversity page says “Finance and innovative financial solutions are key to supporting this transition” to business models that protect biodiversity, and lists its Biodiversity Finance Reference Guide, biodiversity impact metrics (2024) and Blue Finance Guidelines (2025) (own statement). That page names no outcome-bond program, no targets, and neither South Africa nor FirstRand.
The World Bank Group’s best-known outcome bonds were issued by the World Bank’s lending arm (IBRD), with the World Bank itself as issuer: the Rhino bond (2022, $150 million), the Amazon reforestation bond (2024, $225 million), and the Spekboom Restoration Outcome Bond in South Africa, priced on 23 April 2026 at $120 million, with principal “fully protected by the triple-A credit strength of the World Bank” (own statement of IBRD). IFC has co-anchored African bank sustainability bonds before, such as NMB Bank Tanzania’s Jamii bond with British International Investment in 2024 (deal-party statement, BII).
Inference: FR31PB fits IFC’s established role as anchor buyer of emerging-market bank bonds more closely than the IBRD outcome-bond program. In the IBRD bonds the World Bank is issuer and protects principal; in FR31PB IFC is an investor taking FirstRand senior unsecured credit risk. Two World Bank Group nature instruments for restoration in South Africa came to market within four weeks of each other, and no IFC or World Bank source links them.
FSD Africa Investments: R234 million to move from adviser to anchor buyer
What FSD Africa and FSDAi are
FSD Africa was established in 2012 by the UK government, now through the Foreign, Commonwealth and Development Office (FCDO), as a non-profit company based in Nairobi. It calls itself “a specialist development agency working to strengthen African financial markets” (own statement). FSDAi was “set up in 2017 as the investment arm of FSD Africa”, is a for-profit subsidiary, and has had FCDO as a direct shareholder since December 2020. FSDAi describes a “UK-backed specialist development finance investor” with a £309 million capital commitment from FCDO, and says “We invest at the frontier of finance where commercial capital is hesitant to go” (own statement). FSD Africa’s board-approved strategy targets catalyzing £10 billion of private capital by 2030, at least £8 billion of it in local currency.
What it bought
FSDAi “committed R234 million” and, “together with the IFC, anchored the bond”, with its participation helping to “validate the structure and attract other institutional investors” (own statement). FSD Africa later called the investment “catalytic”. The JSE adds that this was FSDAi’s first South African listed debt capital markets investment (deal-party statement), and Reuters-based reporting confirms the amount. Inference: R234 million is about 9.4% of the issue. No source says FSDAi accepted concessionary terms or a first-loss position.
Why it says it invested
FSDAi’s Chief Investment Officer said: “Nature has long been treated as a cost; this bond demonstrates it can be structured as an asset.” She said FSDAi stands with partners “united by the conviction that Africa’s markets are ready to price nature differently”, and that the bond “opens the door to an entirely new asset class in Africa’s capital markets” (own statement). FSD Africa’s write-up of the investment gives three purposes for anchoring: proving the structure, drawing in South African asset managers and pension funds, and creating a template for future nature-linked issues. Its Investment Principal for Private Capital Mobilisation described the problem as ecological benefits being hard to price and verify, leaving conservation reliant on fragmented public and philanthropic money, and said “Instruments like this demonstrate the value of partnership with market innovators to close that gap” (own statement).
The British High Commissioner to South Africa, speaking for FSDAi’s funder and shareholder, said “Nature is critical infrastructure, and linking investment returns to verified environmental improvements shows how finance can drive real resilience”, and linked the bond to “the deepening collaboration between the UK and South Africa to scale sustainable finance” (statement by the UK government).
How it fits FSD Africa’s wider work
FSD Africa’s record in sustainable bonds is mainly technical help to issuers: it reports supporting 23 sustainable bond transactions that mobilized US$1.4 billion in local currency, through reviews, certification support, roadshows, listing and impact reporting (own statement). On NMB’s Jamii bond it gave technical assistance while British International Investment and IFC were the anchors. FSDAi’s earlier capital-markets investments were indirect: a £15 million commitment to the African Local Currency Bond Fund, and £10 million in 2023 to InfraCredit’s Risk Sharing Backstop Facility in Nigeria, which its Chief Investment Officer described as “a derisking financing solution to mobilise short and medium-term local institutional investment” (UK government release). On nature, FSD Africa runs pilots of the Taskforce on Nature-related Financial Disclosures framework, including one with FirstRand, and helped establish the African Natural Capital Alliance (own statement).
Inference: FR31PB appears to be FSDAi’s first direct anchor position in a listed African bond, a step from advising issuers to holding their paper. Its stated aim of pulling South African pension and asset-manager money behind it matches the InfraCredit and local-currency bond fund pattern and the 2030 local-currency target, though FSD Africa does not draw that link itself. The earlier FirstRand pilot shows a prior working relationship; no source says it led to the investment.
Aluwani Capital Partners: R350 million as the local institutional proof
What Aluwani is
Aluwani Capital Partners was created in November 2015 from part of Momentum Asset Management’s institutional business, starting with R62 billion of assets, owned 40% by management, 20% by black economic empowerment partners and 40% by MMI Holdings (deal-party statement, MMI Holdings). In May 2022 management agreed to buy Momentum’s remaining 40% and the empowerment partners’ 20%. Aluwani’s 2026 Stewardship Report gives R169.3 billion under management at 30 June 2026, a B-BBEE Level 1 rating, and the aim of being “A transformative black-owned and controlled asset management business of scale” (own statement). It is an authorized financial services provider serving institutional and individual clients.
What it bought
FSD Africa’s release states that “Aluwani Capital Partners led local institutional participation with a R350 million investment in the bond” (deal-party statement). Aluwani’s own report confirms its participation and does not state the amount or the fund or client mandate that holds it. FirstRand credits it with making the book work: “Strong support and early commitment from Aluwani Capital Partners, a South African asset manager”, helped complete the book build (deal-party statement, JSE). Inference: R350 million is about 14% of the issue, the largest disclosed South African ticket and the second largest overall.
Why it says it invested
Aluwani’s Co-Head of Credit said in the joint release (own statement): “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.” She added: “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.”
Aluwani’s 2026 Stewardship Report case study, “Financing Water Security”, calls its participation “a deliberate effort to allocate capital to this underpenetrated segment”, describes water as “relatively underrepresented in capital markets”, and says “the structure directly links financial returns to verified ecological outcomes.” It describes the split of risk in its own terms: “Investors provide upfront funding and assume execution risk,” while “outcomes-based funders support the return profile through success-linked payments” (own statement). Aluwani gives no separate financial case for the holding, such as yield or credit quality.
How it fits Aluwani’s wider work
Aluwani’s ESG Policy, approved in May 2025, states that it “endorses the United Nations Principles for Responsible Investing (UNPRI)” and the Code for Responsible Investing in South Africa. Its 2026 report sets out a “materiality-led ESG integration” framework. The same report describes no other green, social or sustainability-linked bond holding; its other impact example is its Alternative Credit Fund’s lending to a fiber network. Its public fixed income range has no labeled green or impact strategy (own statements).
Inference: on its own reporting, FR31PB is Aluwani’s first publicized nature-linked bond holding, made through its credit business. Its earlier stewardship reports were not reviewed, so earlier labeled-bond holdings cannot be ruled out. Aluwani’s participation is the evidence FSDAi pointed to when it said its anchor ticket drew in mainstream local asset managers and pension funds.
Where the sources disagree
The sources agree on the three ticket sizes and on all three investors being noteholders. They diverge on the points below.
| Issue | One account | Other account | Assessment |
|---|---|---|---|
| Is Aluwani a co-anchor? | JSE and Business Day: the co-anchors are IFC, FSDAi and Aluwani | FSD Africa and Africa Global Funds: anchored by IFC and FSDAi, with Aluwani leading local participation | Safest wording: named by the JSE as a co-anchor; described by FSD Africa as leading local institutional participation |
| What happens to noteholders if outcomes are missed? | FSD Africa: base return plus success premium; outcome-funder capital is returned for redeployment | Business Day: “investor returns are reduced and that underperformance is channelled back into funding the project itself”; Aluwani: investors “assume execution risk” | Unresolved; only the pricing supplement can show whether noteholders face a reduced coupon or only forgo a premium |
| Where does the R2.5 billion principal go? | IFC: proceeds on-lent to agricultural micro, small and medium enterprises, with returns linked to the clearing project | TNC: TNC South Africa receives R150 million in donations and catalytic funding, with FirstRand Bank as “conditional funding donor” | Inference: the principal funds FirstRand’s balance sheet and the clearing is funded separately; no source states this outright |
| Which catchments? | IFC: Wemmershoek, Steenbras and Berg River | Western Cape Government: the Boland Grootwinterhoek area | Possibly both lie within the program; neither source lists the other’s areas |
| How much water is at stake? | FSD Africa: “up to 55 million litres of extra water a year” | Aluwani: invasive plants cut inflows “by an estimated 55 million cubic meters per year, or approximately 18% of Cape Town’s annual water demand” | Inference: cubic meters is correct; TNC’s “about two months” of annual need matches 18% |
| IFC’s exact amount | ”up to ZAR1.6 billion” (IFC) | “approximately R1.6 billion” (joint release); “1.6 billion rand” (Reuters-based) | Use “about R1.6 billion”; the exact allotment is unpublished |
| FSDAi portfolio size | ”committed £150 million to 27 investments” (release boilerplate) | 21 investments as of June 2026 (FSDAi page) | Probably different counting bases; cite with date |
Dollar conversions also vary (TNC gives the issue as USD 150 million, ESG News about $135 million, IFC US$100.57 million for its own ticket). These reflect different exchange-rate dates; the rand amounts agree.
Implications for BioHubs
The co-anchor story is one of sequencing. IFC’s ticket was approved and invested before the public launch, and both IFC and FirstRand say the bond could not have reached R2.5 billion without it. FSDAi presents its smaller ticket as the signal to South African institutions, and Aluwani’s R350 million is the clearest evidence that local money followed.
Three points follow for a BioHub considering a later bond in the series (structural inference):
- The payment for results rests on a small layer. The disclosed outcome money is about R100 million (FirstRand Foundation and DBSA), small beside the R2.5 billion of notes. A catchment that wants to join a later issue needs outcome funders as much as it needs investors.
- Anchors come from development finance. Both lead tickets came from development finance institutions with mandates to create markets. A later issue in a smaller catchment may need the same kind of anchor.
- The verifiable unit is hectares cleared. The only payment metric named publicly is hectares cleared, not streamflow. A BioHub’s monitoring should be able to report hectares in the form an independent verifier accepts.

Adapted from Cape Water bond co-anchor investors.md, a deep research report written for the W2DF Quartz Repository project on 14 October 2026 from four research strands (IFC, FSD Africa Investments, Aluwani Capital Partners, and the bond’s structure). The unedited report is kept in the workbench. Editorial decisions: converted to American spelling outside quotations; removed working notes addressed to the wiki’s editor; replaced the report’s per-claim source links with the source pages above and the list of further sources; kept the report’s own evidence labels (own statement, deal-party statement, independent reporting, inference) in place of the network’s [IC]/[MS]/[TBV] tags, because on this site [MS] means Michael’s own project documents; and added the closing section on implications for BioHubs, which is structural inference. The spokespeople’s quotations were checked word for word against the FSD Africa joint release on 14 October 2026. On the same date, the investor tiers on the RMB launch source page and Performance-Based Water Bonds were corrected to match this brief.
