For Rand Merchant Bank to review
Rand Merchant Bank has not yet seen this page. It describes the organisation only through what it and its partners have said in public. The Forum has not approached Rand Merchant Bank about anything. Until Rand Merchant Bank has approved the text, it may change. Questions for Rand Merchant Bank:
- Is this description of RMB and its role in the Cape Water bond correct? What would you like to change?
- You have described the bond as the first in a series for South Africa’s strategic water source areas. Is there a public statement of which areas the series may cover?
- Which catchments does the first bond pay for? Do any of them lie in the Riviersonderend mountains?
- Should readers reach you through the moderators, or through a public contact?
Rand Merchant Bank (RMB) is the corporate and investment banking division of FirstRand Bank [IC]. It arranged, structured, and distributed the Cape Water Performance-Based Bond, which it launched on 1 April 2026 [MS]. The bond pays for clearing invasive plants in catchments that feed Cape Town’s dams [IC]. The valley lies downstream of the largest of those dams, Theewaterskloof [IC].

What it does
RMB is the corporate and investment banking arm of FirstRand Bank [IC]. RMB’s own website describes it as a division of FirstRand Bank Limited [MS].
How its work reaches the valley
The bond. RMB announced the bond on 1 April 2026 as Africa’s first nature-linked outcomes-based bond [MS]. FirstRand Bank issued it, and it was listed on the Johannesburg Stock Exchange on 17 April 2026 [IC]. Part of what investors earn is linked to independently verified restoration [IC]. An RMB spokesperson called it “a R2.5 billion market signal that natural capital has entered mainstream finance” [MS].
A series. RMB describes the bond as the first in a series designed for South Africa’s 22 strategic water source areas [MS]. These areas cover about a tenth of South Africa’s land and supply about 60 percent of its water [MS].
Where the money goes. The Nature Conservancy South Africa clears invasive plants through the Greater Cape Town Water Fund, in remote priority catchments of the Western Cape Water Supply System [MS]. Conservation Alpha checks the results [MS].
The valley. Theewaterskloof Dam, on the Riviersonderend near Villiersdorp, is the largest dam in the Western Cape Water Supply System [IC]. The valley lies downstream of it, where the Gobos and Baviaans rivers join the Riviersonderend [IC]. Wild Restoration, which clears invasive plants in the Riviersonderend mountains above Greyton, has told the Forum that the Greater Cape Town Water Fund supports clearing in those mountains through a partnership with CapeNature [TBV]. Which slopes that covers, and whether they drain into the dam or into the valley’s own rivers, is not yet known.
Where it touches this site
- Ridge to River to Table, an idea not yet agreed, proposes that the valley prepare for a later bond in RMB’s series, and that the idea be put to RMB only after the Forum and the Transformasie Komitee have considered it. RMB has not been approached.
- Restoring the River, an idea not yet agreed, explains the water fund and the bond as an example of what cities pay for clean water.
- From Water Access to Water Agency, an idea not yet agreed, cites the bond as proof that buyers for catchment results already exist.
- The Laws That Shaped the Valley lists the bond’s launch in April 2026 as a market signal.
What is still open
- Which strategic water source areas a later bond in the series may cover. No public statement has been found.
- Which catchments the first bond pays for, and whether any lie in the Riviersonderend mountains.
