A bankable feasibility study is the evidence base a sponsor must establish to show that a project's commercial and financial case is credible enough to fund.
For South African project sponsors, boards and accounting authorities, building that evidence before committing capital is how statutory duties are met, waste is eliminated and viability is secured.
Bankability and the mandate to test before committing
In capital-project development, "bankable" means a project's business case has reached a level of commercial rigour, financial viability and risk mitigation sufficient for an external funder or an internal capital committee to commit with confidence. A sponsor cannot assume bankability; it has to be established through a thorough feasibility study before any binding financial commitment is made. Starting execution or deploying capital on an unproven concept exposes the sponsor to serious financial loss, operational disruption and governance failure.
In the public sector, the duty to verify bankability before committing capital is anchored in statutory financial management. The PFMA as administered by National Treasury requires institutions to practise good financial management that maximises service delivery through the efficient use of limited public resources. It expressly requires the elimination of waste in the use of public assets, which obliges accounting officers and accounting authorities to vet capital investments thoroughly before public funds are allocated.
In the corporate sphere, the Companies Act 71 of 2008 establishes that the board directs the company's affairs and governs the relationships between the company, its shareholders and its directors. Allocating corporate capital to an unproven project without a bankable feasibility study abdicates that core board responsibility and undermines shareholder value.
The commercial case and output alignment
The commercial case in a bankable feasibility study asks whether a genuine market demand or public-service need exists to justify the proposed investment. It interrogates whether the project aligns with the institution's mandate, whether the proposed operating model can realistically deliver the capability, and whether market or institutional conditions will support ongoing operations. It also examines the supply-chain constraints, demand volatility, regulatory requirements and environmental risks that could undermine delivery.
For a public institution, the commercial case is framed by the outputs- and accountability-driven approach of the PFMA as administered by National Treasury. Rather than judging viability purely on financial return, a public-sector feasibility study assesses whether the project will reliably produce its intended service outputs and contribute to the predetermined objectives. The sponsor has to demonstrate that the operating model can generate those outputs within the authorised operational parameters.
Financial viability, funding and affordability
Where the commercial case establishes demand and operational feasibility, the financial case shows how the project will be funded and sustained across its whole operational life. It examines the prospective funding sources, tests whether capital can be secured on viable terms, and asks whether operational cash flows or budget appropriations will cover maintenance, debt servicing and running costs. Kept conceptual, the work is about long-term affordability and financial sustainability, not a set of flattering projections.
The integrity of the financial case rests entirely on the reliability of the underlying accounting data and record-keeping. Under the Companies Act 71 of 2008, the Financial Reporting Standards Council advises on the requirements for financial record-keeping and reporting, which helps ensure the data feeding the project models is accurate and compliant. For public institutions, the PFMA as administered by National Treasury enforces sound financial management systems and internal controls to prevent overspending.

— Synthesis of South African regulatory guidance
The PFMA's budget-process chapter governs multi-year budgets and carries a specific clause on unfunded mandates, so a public-sector financial case must align with the multi-year budget framework and make sure long-term operating obligations do not become unfunded commitments that destabilise the institution.
Stress-testing assumptions and allocating risk
A feasibility study rests on a chain of forward-looking assumptions about demand, input costs, operational efficiency, delivery timelines and the wider economy. Because external funders and investment committees will stress-test those premises, the sponsor should identify the weakest assumptions first and show how sensitive the project's viability is to adverse change. A project that only works under ideal conditions is, by definition, not bankable.
A bankable study also allocates project risk explicitly among the parties involved. The sponsor has to define precisely which party — sponsor, contractor, operator, funder or supplier — carries each operational, financial and environmental risk. A clear, contractual distribution of risk puts each one with the party best placed to manage it, and stops unquantified liabilities drifting back onto the sponsor.
Governing the feasibility decision
Deciding whether a project has established a bankable case is a governance decision that belongs to the sponsor's board or the public entity accounting authority. External technical, legal and financial advisers help prepare the study, but the go or no-go decision cannot be outsourced to consultants. The governing body has to weigh the objectivity and independence of the study itself, and satisfy itself that the advisers have not produced optimistic projections simply to justify approval.
That ownership is anchored in statutory fiduciary duty. Under the Companies Act 71 of 2008, directors hold fiduciary duties to direct the company's affairs responsibly and safeguard shareholder interests. Under the PFMA as administered by National Treasury, accounting officers and accounting authorities carry strict fiduciary duties to operate basic financial systems, prevent overspending and protect public assets. Committing funds to an unproven or unbankable project is a governance failure, and the PFMA enforces these duties through strict disciplinary sanctions — up to dismissal, and prosecution for gross financial misconduct — against accounting officers and accounting authorities who are negligent in committing public resources.
What good looks like
For project sponsors, boards, accounting officers and accounting authorities, a bankable feasibility study takes an integrated, statute-grounded approach to capital allocation. Excellence begins when leadership treats bankability as an objective evidence base that must be proven before any capital is committed. The sponsor validates the commercial demand and operational capability, and makes sure a public project aligns directly with the predetermined service-delivery objectives under the PFMA as administered by National Treasury.
In practice, exemplary feasibility governance shows up when the financial case rests on reliable record-keeping advised on by the Financial Reporting Standards Council under the Companies Act 71 of 2008, while respecting the PFMA's multi-year budget framework and avoiding unfunded mandates. It is reflected in stress-testing the critical assumptions and setting a clear contractual allocation of risk across the project partners. Effective governing bodies keep non-delegable ownership of the go or no-go decision, weigh the advisers' independence, and uphold the fiduciary duties to eliminate waste and protect institutional assets. A bankable feasibility study is what turns a project concept into a viable, fully resourced and lawful investment.
For a procurement-linked manufacturing investment, distinguish a policy ambition from committed demand and test the supplier’s qualification and production cash cycle. The industrial localisation framework sets out those capability questions alongside the project’s financing case.

Frequently Asked Questions
What is a bankable feasibility study?
A bankable feasibility study is the essential evidence a project sponsor must establish to demonstrate that a project's commercial and financial case is credible enough to secure funding. It signifies that the business case has achieved sufficient commercial rigour, financial viability, and risk mitigation for funders or capital committees to commit with confidence. Kettle Consulting sees this as the critical step to ensure capital is deployed effectively and responsibly.
Who in South Africa is required to conduct a bankable feasibility study, and when does this requirement apply?
In South Africa, bankable feasibility studies apply to project sponsors, boards, and accounting authorities in both the public and corporate sectors. Under the Public Finance Management Act (PFMA) as administered by National Treasury, public institutions must conduct these studies before allocating public funds. Similarly, the Companies Act 71 of 2008 implies this responsibility for corporate boards before committing capital to projects.
What is the underlying mandate for conducting a bankable feasibility study, and why is it crucial for South African entities?
The underlying mandate stems from statutory financial management, such as the Public Finance Management Act (PFMA) and the Companies Act 71 of 2008. It is crucial because it ensures good financial management, maximises service delivery, eliminates waste, and secures project viability before committing capital. Kettle Consulting observes that this process directly supports fiduciary duties to protect institutional assets and shareholder value.
What does successful compliance with bankable feasibility study requirements entail, and what are the consequences of failure?
Successful compliance involves leadership treating bankability as an objective evidence base, validating commercial demand, and aligning public projects with service-delivery objectives under the PFMA. It also means the financial case rests on reliable record-keeping, critical assumptions are stress-tested, and risk is clearly allocated. Failure to comply can lead to serious financial loss, operational disruption, governance failure, and under the PFMA, strict disciplinary sanctions including dismissal and prosecution for gross financial misconduct.
Where do South African organisations most commonly falter when conducting bankable feasibility studies?
Organisations often falter by assuming bankability rather than establishing it through rigorous study before committing capital, or by deploying funds on unproven concepts. Another common mistake is failing to adequately stress-test assumptions, leading to projects that only work under ideal conditions. Kettle Consulting frequently observes that governing bodies sometimes outsource the critical go or no-go decision, rather than retaining ownership and critically evaluating adviser objectivity.
