- AfDB’s US$10mn Tanzania Guarantee Tests Whether Risk-Sharing Can Unlock SME Trade
The African Development Bank has agreed to provide a US$10mn trade-finance guarantee to Exim Bank Tanzania, seeking to reduce the payment risks that restrict smaller businesses from accessing international trade.
The agreement, signed on September 28, 2026, will allow the AfDB to cover up to 100% of eligible non-payment risks associated with letters of credit and similar trade instruments issued by the Tanzanian bank.
The facility is intended primarily to support small and medium-sized enterprises and domestic companies engaged in imports. Its potential significance, however, extends beyond the US$10mn headline amount.
Unlike a conventional loan, the AfDB is not immediately transferring US$10mn to Exim Bank Tanzania. It is using its balance sheet and credit standing to assume specified risks that would otherwise be carried by international confirming banks.
This protection could make foreign and regional banks more willing to accept trade instruments issued by Exim Bank Tanzania, allowing a relatively small guarantee to facilitate a larger volume of transactions over time.
The distinction matters. The success of the arrangement should not be measured simply by the size of the guarantee but by how much additional private financing it mobilises, the number of enterprises supported and the productive value of the goods financed.
“This facility is in line with the African Development Bank’s Cardinal Points on managing risk and mobilising capital, unlocking SME financing, as well as enhancing Africa’s regional integration and elevating its role in global markets,” AfDB Country Manager for Tanzania Mary Monyau said.
Trade finance is one of the less visible barriers confronting African businesses.
A commercially viable company may have a confirmed order and a reliable overseas supplier but still be unable to complete a transaction because its bank lacks the international relationships or risk capacity required to issue an acceptable letter of credit.
Smaller companies are disproportionately affected. They often have limited collateral, short credit histories and less bargaining power with banks. International financial institutions may also attach a higher risk premium to transactions involving smaller African lenders.
An earlier AfDB assessment estimated Tanzania’s unmet demand for trade finance at approximately 9% of gross domestic product. Against that gap, a US$10mn guarantee is modest.
Its value lies instead in risk transfer. If the AfDB’s participation encourages confirming banks to accept transactions they would otherwise reject, the facility could help Exim Bank Tanzania expand trade financing without bearing all the associated exposure.
Exim Bank Tanzania aims to increase its trade-finance portfolio by approximately 15% annually over the next three years, supported by additional relationships with regional and international development institutions.
“This partnership represents more than a financing arrangement; it strengthens the financial infrastructure required to support Tanzania’s growing trade ambitions,” Chief Financial Officer Shani Kinswaga said.
“For Exim Bank, it provides an important opportunity to deepen our trade-finance business while supporting Tanzanian businesses to participate more confidently in regional and international markets.”
The broader economic impact will depend on the types of transactions approved.
If the facility supports imports of machinery, agricultural equipment, pharmaceutical inputs and intermediate goods, it could help Tanzanian firms expand production, raise productivity and enter regional supply chains.
A manufacturer that imports modern machinery, for example, could increase output and eventually compete in export markets. Agricultural equipment could improve farm productivity, while production inputs could allow domestic companies to substitute locally manufactured goods for finished imports.
The same guarantee would produce a different outcome if it were concentrated on finished consumer goods. Such transactions may still be commercially legitimate, but they would do less to strengthen domestic productive capacity and could deepen import dependence.
The AfDB and Exim Bank will therefore need to assess more than repayment risk. They should also monitor whether the portfolio advances industrialisation, employment creation and export competitiveness.
This does not require turning a commercial facility into a subsidy programme. It means recognising that the development value of one dollar of trade finance can differ considerably depending on the transaction it supports.
The facility could also strengthen Tanzania’s participation in the African Continental Free Trade Area by making it easier for domestic businesses to transact with suppliers and buyers elsewhere on the continent.
Letters of credit and bank guarantees can reduce uncertainty between companies operating in different jurisdictions, particularly where commercial relationships are new and parties are unwilling to rely on open-account transactions.
Improved financing could therefore help Tanzanian enterprises establish regional supply relationships and exploit the larger market created by AfCFTA.
But finance is only one part of the challenge.
Businesses must still contend with transport costs, border delays, regulatory differences, customs procedures and other non-tariff barriers. A company may obtain financing and still struggle to move goods efficiently across borders.
The guarantee should consequently be viewed as one component of a wider trade ecosystem rather than a complete solution to Tanzania’s competitiveness constraints.
The agreement reflects a broader change in how multilateral development institutions deploy capital.
Instead of financing every transaction directly, institutions such as the AfDB are increasingly using guarantees to attract commercial banks into markets or segments they consider too risky.
This approach can stretch scarce development capital further because the guarantee is called only if a covered borrower fails to meet an eligible payment obligation.
It also carries risks. If guaranteed banks weaken their own credit assessments because a multilateral institution absorbs the exposure, risk-sharing can create poor lending incentives. Strong eligibility criteria, transaction monitoring and transparent reporting will therefore be essential.
The agreement aligns with Tanzania Vision 2050 and the AfDB’s 2026–2031 country strategy, both of which emphasise private-sector development, competitiveness and employment.
Yet those objectives will not be achieved by signing the facility alone.
The decisive indicators will be the volume of transactions completed, the share reaching SMEs, the sectors receiving support, the additional financing mobilised and the number of companies that graduate into sustainable regional or international trade.
The US$10mn guarantee is therefore best understood as an experiment in leverage.
If it allows Exim Bank Tanzania to finance productive imports, crowd in international banks and build the trading capacity of domestic enterprises, its economic impact could exceed its nominal value.
If it merely insures transactions that would have occurred anyway or finances consumption without supporting production, the development return will be much smaller.
The agreement creates financial space. What Tanzania’s businesses and banks do with that space will determine whether it becomes another trade-finance facility or a meaningful instrument of economic transformation.
