A board may approve a promising investment on the strength of demand forecasts and a projected internal rate of return. A development finance institution will ask a different question: can this project withstand scrutiny when the market softens, approvals take longer, or foreign-currency costs move?
A bankable feasibility study answers that question with evidence, not optimism. For sponsors considering feasibility studies and market research Africa, the work must connect commercial demand, host-country approvals, technical delivery, environmental and social obligations, and governance into one investment case.
As of October 2026, there is no single African investment law, revenue authority, currency or licensing framework. A solar project in one jurisdiction, a processing plant in another and a logistics asset crossing borders each require their own regulatory and fiscal assumptions before a lender can rely on the numbers.
What makes a feasibility study bankable
A feasibility study becomes bankable when it gives a DFI enough evidence to assess commercial viability, development impact, implementation readiness and risk allocation. It must also show who will deliver the project, who will buy the output, and how the business will remain solvent over the financing period.
The African Development Bank’s non-sovereign funding materials call for a full-scope feasibility study, a developed financial model, an independent market study, financing and equity details, off-take terms, ownership information, procurement status and operating arrangements. The reason is practical: debt providers cannot finance an asset from a sponsor presentation alone.
For many projects, the study should cover these connected workstreams:
1. Market demand and route to market.
2. Technical design, construction and operating plan.
3. Regulatory, tax, foreign-exchange and licensing assumptions in the exact host jurisdiction.
4. Financial model, funding structure and downside cases.
5. Environmental and social risk, mitigation and stakeholder engagement.
6. Sponsor capability, beneficial ownership, governance and internal controls.
7. Development impact that can be measured and monitored.
If one workstream sits outside the model, the investment case has a gap. Environmental mitigation that has no cost line, for example, can make a projected return look stronger than the project can actually deliver.
Step 1: Define the investment and the decision it must support
Start with a precise project definition. State the asset, site, capacity, target customer, proposed capital structure and the decision sought from the lender. “A regional manufacturing expansion” is too broad. “A 20,000-tonne annual processing facility serving named customer segments under identified supply arrangements” gives the study a testable foundation.
Set the host jurisdiction before commissioning research. Identify the responsible investment agency, tax authority, environmental regulator, sector regulator, municipal authority and, where relevant, central bank or exchange-control authority.
This step matters because “Africa” cannot carry a tax rate, a permit assumption or a repatriation rule. The feasibility team must verify every approval, timeline and fiscal treatment in the country where the asset will operate before it submits the investment case.
Build an approvals register early
Create an approvals register with the permit or licence, issuing body, submission requirements, lead time, dependency, renewal requirement and project owner. Include land rights, construction approvals, environmental authorisation, utility connections, operating licences and import arrangements where the project needs equipment or inputs from outside the host country.
Do not wait for financial close to ask whether an environmental and social impact assessment is required. The assessment can affect site design, construction timing, community engagement and mitigation costs, all of which affect debt service capacity.
Step 2: Prove demand with independent market evidence
DFIs test the market section closely because many feasibility studies begin with a conclusion, then select evidence to support it. An assertion that a country has an “unmet need” does not establish that customers will buy at the price required for the project to work.
A credible market study quantifies demand, production, sales, imports, exports, market forecasts, competitors, distribution channels and sales arrangements. It identifies the evidence behind each forecast and separates confirmed demand from management assumptions.
Ask direct questions:
● Who buys the product or service, and what do they buy instead today?
● What price can the project achieve after transport, duties, distributor margins and customer credit terms?
● Which competitors can add capacity or cut prices?
● What contract, purchase order, letter of intent or off-take arrangement supports projected volumes?
Take an illustrative food processor with a proposed US$18 million plant and projected annual sales of US$14 million. Its first model assumes that imported products will automatically convert to locally produced stock. Independent interviews may show that two large buyers require 60-day credit and audited quality certification before they change suppliers, which delays early revenue and increases working-capital needs. The sponsor should revise the ramp-up and cash-flow profile before approaching a lender, rather than defend a sales forecast that procurement teams have not validated.
Step 3: Build a financial model that survives lender scrutiny
A lender-grade model covers the life of the loan and links operations to revenue, operating costs, taxes, profit, balance sheet and cash flow. It reconciles with the financing plan and separates local-currency from foreign-currency capital costs.
That separation matters in African investments because imported equipment, foreign debt and local operating revenue can sit in different currencies. A project can show a healthy headline return while still failing to service hard-currency debt after an exchange-rate movement or a delayed tariff adjustment.
At minimum, model:
● Capital expenditure, contingencies and timing of drawdowns.
● Working capital, including inventory, debtor days and supplier terms.
● Output, prices, volumes and ramp-up assumptions.
● Operating costs, maintenance and replacement capital.
● Tax assumptions that have been verified in the host jurisdiction.
● Debt terms, equity timing and repayment profile.
● Downside cases for volume, price, construction cost, delay and foreign exchange.
The African Development Bank states that its project financing is generally capped at 33% of total project cost. Sponsors should therefore show where the remaining capital will come from, when equity arrives and what happens if another financier delays its commitment.
A US$30 million project seeking US$10 million from a DFI illustrates the point. The 33% share aligns with the general cap, but the project still needs a credible plan for the remaining US$20 million, including committed sponsor equity and any senior or local debt. If that capital is only described as “expected,” the feasibility study has not yet established a financeable structure.
Do not lead with IRR alone
An internal rate of return helps an equity investor compare opportunities. It does not tell a lender whether the project can meet scheduled debt obligations in a weaker operating year.
Show the assumptions behind the return, the cash available for debt service and the consequences of downside scenarios. If management cannot explain why a 10% fall in sales volume affects cash flow differently from a 10% increase in capital cost, the model needs more work before it goes to a credit committee.
Step 4: Treat environmental and social work as a core project input
IFC assesses projects according to environmental and social risk and requires clients to meet applicable responsibilities under its Performance Standards. Depending on the risk profile, the project may need an environmental and social impact assessment and an action plan.
The study should identify risks, impacts, mitigation actions, waste systems, affected communities and stakeholder engagement arrangements. It should also place the cost of these commitments in the capital and operating budgets.
This is where sponsors often make the costly mistake of treating environmental work as a permitting appendix. A revised waste-water system, resettlement issue, labour accommodation requirement or community grievance process can change design, programme and operating cost.
Take an illustrative logistics depot with a US$8 million construction budget near a growing urban area. During site work, the sponsor identifies that truck movements will affect neighbouring businesses and that drainage design needs additional controls. A US$350,000 mitigation allowance and a revised traffic plan may reduce the apparent return, but they produce a more credible construction schedule and a clearer case for responsible financing.
As of October 2026, IFC and MIGA are updating their Sustainability Framework. The process remained in consultation during 2026, so sponsors should not present proposed revisions as current mandatory requirements. They should, however, monitor the final framework because future lender expectations may change.
Step 5: Show governance, ownership and delivery capability
A DFI will assess the people and entities behind the project as carefully as the asset. The feasibility study should identify beneficial owners, shareholders, directors, management, related companies, internal controls, integrity safeguards and board arrangements.
Include three years of audited financial statements where they apply, together with evidence of the sponsor’s ability to fund its equity commitment. Explain relevant delivery experience, but do not overstate it. If the sponsor has not built a project at this scale, show the EPC contractor, operating partner and governance controls that close the capability gap.
Off-take, EPC and operations and maintenance arrangements belong in the same evidence pack. A financially attractive facility does not become investable until the lender can see who will build it, who will run it and who will purchase its output.
Step 6: Quantify development impact and DFI additionality
Development impact is not self-evident because a project creates jobs or produces locally. Define the outcomes that the investment will deliver, how the project will measure them and why DFI participation adds value beyond commercial finance.
Depending on the sector, this may include direct and indirect employment, local procurement, value added, import substitution supported by real customer demand, women’s economic participation, emissions outcomes or improved access to an essential service. Use a baseline and a measurement method, because broad statements about impact do not support monitoring after disbursement.
DFI additionality may arise from longer tenors, risk sharing, environmental and social expertise, mobilisation of co-financiers or support for an investment commercial lenders will not finance on comparable terms. State the specific constraint. “The project needs patient capital” is less useful than identifying the financing gap, currency mismatch or risk allocation that constrains private funding.
Common weaknesses we see before DFI engagement
The first weakness is a sponsor-built market forecast with no independent evidence. Correct it through customer research, competitor analysis and documented off-take discussions.
The second is a model that uses one currency for simplicity when the project earns, spends and borrows in different currencies. Correct it by separating exposures and testing the downside case.
The third is an approvals list without accountable owners or timing. Correct it through a live regulatory register that management reviews alongside the implementation plan.
The final weakness is a feasibility study that describes environmental and social risks but does not price the response. Correct it by linking every mitigation measure to design, budget, programme and governance.
Frequently Asked Questions
What is a bankable feasibility study?
A bankable feasibility study is an evidence-based assessment that allows lenders and investors to evaluate whether a project can operate, generate cash, meet obligations and manage its risks. It goes beyond a business plan by testing assumptions through market, technical, financial, regulatory, environmental and governance analysis.
Does every DFI use the same feasibility-study template?
No. There is no universal DFI application form or prescribed feasibility-study template for all African projects. Each lender, sector and host jurisdiction can require different information, so we tailor the evidence pack to the financing strategy and approvals pathway.
How much funding can the African Development Bank provide?
The African Development Bank states that project financing is generally capped at 33% of total project cost. The final amount depends on the transaction, co-financing plan, risk assessment and the Bank’s approval process.
When should environmental and social assessment begin?
Begin during feasibility work, before the design and financial model are fixed. Early work allows the project team to incorporate mitigation, stakeholder engagement, waste arrangements and potential action-plan costs into the investment case.
A fundable project needs more than an attractive opportunity. It needs a disciplined case that gives investors confidence in the assumptions, the sponsors and the route to delivery.
