Structure and Capital Market Tool

In March 2022, NMB Bank issued the Jasiri Bond, a three-year gender bond at par with a gross coupon rate of 8.5% per annum. The bond raised TZS 74 billion (approximately USD 32 million) and was 197% oversubscribed, reflecting strong investor demand. The bond was listed on the Dar es Salaam Stock Exchange (DSE) and matured in 2025, with NMB Bank meeting all principal and interest obligations in full and on time.


The Jasiri Bond was the first gender bond from Sub-Saharan Africa to be listed on the Luxembourg Stock Exchange (LuxSE), with its listing displayed on the Luxembourg Green Exchange (LGX). Although secondary trading took place exclusively on the DSE, the Luxembourg listing enhanced the international visibility of Tanzanian sustainable finance instruments and raised the profile of gender-labelled bonds among global investors. The issuance was conducted under NMB Bank's Social Bond Framework, which aligned with the International ICMA Social Bond Principles and reflected the bank's mission to promote human development and social inclusion.


As the first gender-labelled bond in East Africa, the transaction sought to introduce a new thematic asset class into a market where neither issuers, investors, nor regulators had prior experience with gender-labelled debt. Beyond NMB's willingness to issue, coordinated interventions by different institutions to address first-mover barriers contributed to the bond's successful launch.


The International Finance Corporation (IFC) acted as the anchor investor, subscribing to 31% of the issuance (approximately USD 10 million in Tanzanian shillings), and thus providing an early demand signal and encouraging participation from other investors in a first-of-its-kind issuance. This support strengthened the transaction's credibility and investor confidence in the bond's alignment with internationally recognised social finance standards.

Background and Market Context

Women-owned and -led businesses in Tanzania face persistent financing constraints. Limited collateral, information asymmetries, and constrained access to formal credit have left approximately 75% of female-owned businesses underserved. This contributes to an estimated USD 42 billion financing gap for women-led enterprises across Africa.


Established in 1997, NMB Bank Plc (NMB) has grown into one of Tanzania's leading commercial banks serving retail, SME and corporate clients. Managing over 9.9 million customer accounts through 248 branches, 735 automated teller machines (ATMs) and 4,088 employees, NMB was Tanzania's most profitable bank in 2025.


To address these financing constraints, NMB introduced the Jasiri Bond, East Africa's first gender bond, to mobilise capital for women-owned and women-led SMEs. Jasiri, meaning brave in Swahili, reflects the bank's ambition to expand access to finance for women entrepreneurs. The bond was issued as the fourth and final tranche under NMB's 2016 medium-term note (MTN) programme, established to diversify the bank's funding base and strengthen its long-term sources of capital.

Development Impact

IFC's anchoring of the bond represents a demand-side intervention. Its participation helped establish market confidence in East Africa's first gender bond. It contributed to a 197% oversubscription and signalled investor appetite for credible gender-focused debt instruments.


NMB used the bond proceeds to expand lending to women entrepreneurs, supporting business growth, job creation, and SME development in Tanzania. The bond also improved financing conditions by enabling loans at an interest rate of approximately 14%, compared with prevailing market rates of around 19%. The Jasiri Bond established a market precedent for gender-labelled debt instruments in the region, providing a replicable model for other EMDEs seeking to mobilise domestic capital markets for sustainable development.
