NMB Made TZS 760 Billion. CRDB Made TZS 729 Billion. Tanzania's Two Largest Banks Both Posted Records in 2025. Here Is What the Numbers Behind the Numbers Actually Tell You.

DAR ES SALAAM — Tanzania's two largest listed banks closed 2025 with the closest profit figures they have ever recorded. NMB Bank posted profit after tax of TZS 760.1 billion, up 17.6 percent year on year, on total income of TZS 1.825 trillion. CRDB Group posted TZS 728.6 billion, up 32.1 percent, on operating income of TZS 1.884 trillion. By the measure that typically dominates the headline, absolute profit, the gap between them has effectively closed. The convergence is real but misleading as an analytical conclusion. It obscures structural differences in how the two banks earn money, how they deploy capital, what risks they are accumulating, and what strategies they have committed to for the next five years. Reading the 2025 results through the profit headline alone is like reading Tanzania's GDP growth figure without looking at its sectoral composition. The number is accurate. The picture it gives you is incomplete. This analysis goes inside both sets of results to find what the headline numbers do not tell you. Both banks are printing money. The divergence is in how. NMB's balance sheet reached TZS 17.6 trillion in 2025, growing 28 percent year on year. CRDB's hit TZS 22.3 trillion, growing 33.6 percent. CRDB is 27 percent larger by total assets and growing faster. NMB is the more profitable bank per unit of equity deployed, with a return on average equity of 27 percent against a Tier 1 capital ratio of 24.7 percent. CRDB delivered a 29.5 percent ROAE on a Tier 1 capital ratio of 16.1 percent. The capital structure comparison is the starting point for understanding the ROE figures correctly. CRDB's higher ROAE is not evidence of a more efficient business. It reflects a leaner capital structure that amplifies returns on a smaller equity base. NMB is generating its 27 percent return with substantially more equity on the table. Both are comfortably above the Bank of Tanzania's regulatory minimums of 12.5 percent Tier 1 and 14.5 percent total capital adequacy. But NMB's capital surplus is so large, a total capital adequacy ratio of 24.8 percent against the 14.5 percent minimum, that it creates a different set of strategic questions about deployment than CRDB's more efficiently leveraged position. This is not a criticism of either bank. It is the correct analytical frame for reading the ROE comparison honestly, and it becomes relevant when considering what Agenda 2030 means for NMB and what the DRC expansion means for CRDB. NMB: the compounding machine finishing one chapter, opening another The 2025 report formally closes NMB's 2021 to 2025 Medium-Term Plan. The five-year results are worth stating in full because they describe the compounding dynamic that has produced the bank's current position. Total assets grew at a 19 percent compound annual growth rate over the period. Net profit compounded at 26 percent annually. The customer base expanded from approximately 4 million to 9.9 million. The Wakala agent banking network grew from 8,410 outlets to 73,592, the largest agency banking network in Tanzania's banking sector by a significant margin. The financial architecture behind that growth is deliberately conservative in ways that make the output numbers more impressive rather than less. The cost-to-income ratio reached 38 percent in 2025, an all-time low for the bank and exceptional by any East African regional comparison. The closest comparable for a large commercial bank in East Africa running similar transaction volumes and customer numbers would typically land between 42 and 48 percent. NMB's 38 percent reflects the economic consequence of a decade of investment in digital channels and agent banking: transactions that flow through digital or Wakala channels cost a fraction of what the same transaction costs through a branch, and 98 percent of NMB's transaction volumes now move outside branches. The net interest margin of 8.3 percent requires contextualising. It declined from approximately 10 percent in 2022 and 2023 as the interest rate environment shifted, but it remains high enough to generate strong pre-provision income on a TZS 10.4 trillion loan book. The NPL ratio of 2.5 percent is the cleanest it has been in five years, improving consistently from 4 percent in 2021, with a coverage ratio of 96 percent and impairment charges of TZS 82 billion that are modest in proportion to the book. Non-funded income reached TZS 635 billion, representing 34.8 percent of total income. The diversification is structurally real rather than cyclically inflated, driven by fee and commission income from digital channels, agency banking, and card services whose volume scales with transaction count rather than with interest rates. This matters for the interest rate sensitivity of NMB's earnings: a larger non-funded income base provides a buffer against NIM compression that a purely interest-income-dependent bank cannot access. The capital position is where NMB's situation becomes most interesting for investors. A CET1 ratio of 24.71 percent and total capital adequacy of 24.8 percent are not simply regulatory buffers. They represent capital generating excess returns faster than the bank can currently deploy it into risk-weighted assets. The board's response was a total proposed dividend of TZS 610.15 per share, comprising TZS 504.26 as the ordinary dividend and TZS 105.89 as a special dividend, implying a payout ratio of 40.3 percent against the standard one-third policy. The special dividend is a signal that management is acknowledging capital surplus rather than simply sitting on it. At the closing DSE share price of TZS 8,410, the implied dividend yield is approximately 7.3 percent. Book value per share is TZS 5,770. The price-to-book ratio of 1.46 times and price-to-earnings of 5.8 times place NMB at a discount to comparable African consumer banking franchises where two to three times book is common for banks with return profiles of this quality. Agenda 2030, NMB's incoming five-year plan, prioritises four strategic moves: deepening retail through segment-specific propositions beyond mass market accounts, building a fully integrated SME ecosystem encompassing payments, insurance, and advisory alongside lending, expanding wholesale wallet share through sector-specific value-chain solutions, and selectively extending into adjacent financial services. The logic is sound. NMB has spent five years building one of East Africa's most impressive distribution networks. The question Agenda 2030 is trying to answer is whether that distribution can now be monetised at higher revenue per customer rather than simply more customers. That is a harder game than adding accounts. It requires product depth, relationship management at scale, and the ability to cross-sell in a market where consumers have historically used banks for narrow transaction services. NMB's 2025 results suggest the platform is capable of the execution. Whether the market and the competitive environment will allow it is the variable. CRDB: the bigger engine, mid-build CRDB's FY2025 report tells a different story, one of deliberate scale-building across Tanzania, Burundi, and the Democratic Republic of Congo, at a pace that few East African banks have attempted simultaneously with quality maintenance. Total assets grew 33.6 percent to TZS 22.3 trillion. Customer deposits grew 36.5 percent to TZS 14.9 trillion. Loans and advances grew 32.5 percent to TZS 13.7 trillion. These are not incremental improvements. They are structural step-changes in balance sheet size whose sustainability across a multi-year period requires both credit discipline and operational capacity that cannot be assumed simply because the 2025 numbers look good. The credit discipline test is the one that matters most for a bank growing loans at 32 percent annually. CRDB's NPL ratio held flat at 2.9 percent despite the rapid loan growth, and the cost of risk dropped to 0.40 percent from 0.50 percent in 2024. Growing a book at 32 percent while keeping NPLs flat is harder than the number suggests. New loans are underwritten against current conditions, but their quality reveals itself over the subsequent 12 to 24 months. The flat NPL ratio in 2025 is reassuring. The watch period for the quality of 2024 and 2025 vintage loans extends into 2026 and 2027. The gross loans-to-deposit ratio of 94 percent is also worth noting: CRDB is running the balance sheet aggressively, close to its own internal ceiling of 95 percent. The efficiency story at CRDB is the most impressive single trend across the four-year period visible in the results. The cost-to-income ratio fell to 41.6 percent in 2025 from 45.7 percent in 2024 and 55.3 percent in 2021. A 14-percentage-point improvement in four years on a rapidly scaling balance sheet represents genuine operating leverage rather than cost-cutting that damages revenue generation. The medium-term target of 43 percent suggests management believes it has further efficiency to extract, though the pace of improvement naturally slows as the easier structural wins are realised and the regional complexity of the Group structure adds cost. The strategic partnerships dimension of the 2025 report deserves more attention than it has received in early commentary. The formalised relationship with Sumitomo Mitsui Banking Corporation, one of the largest financial institutions in the world, is designed to deepen trade and investment facilitation, broaden cross-border business capacity, and strengthen institutional links with global financial ecosystems. This is not a branding announcement. A structured relationship with SMBC opens correspondent banking lines, deal flow from Japanese and global corporate clients seeking East African access, and institutional credibility in the structured finance and project finance markets where CRDB has the balance sheet to compete if it has the relationships to source the transactions. The Sukuk programme is building quietly toward what could become a meaningful competitive advantage. CRDB issued the CRDB Al Barakah Sukuk in 2025, raising TZS 125.4 billion and USD 32.3 million. Islamic financing assets reached TZS 338.8 billion on the balance sheet. Sukuk investments stood at TZS 44.7 billion. These are small numbers relative to a TZS 13.7 trillion loan book, but the market they address is structurally underpenetrated. Tanzania has a significant Muslim population and a near-total absence of established Islamic banking alternatives operating at commercial scale. CRDB is building the franchise infrastructure, the Shariah board, the product set, the distribution, and the brand association, that will be difficult to replicate quickly if and when competitors decide the market is large enough to contest. Insurance revenue grew 96 percent to TZS 41.4 billion. The Kijani Green Bond was listed on the DSE, broadening the capital market instruments available to Tanzanian investors and positioning CRDB within the ESG financing infrastructure that international development finance institutions are increasingly directing capital through. Non-funded income stands at 31.2 percent of operating income against a medium-term target of 39 percent. The gap between the current position and the target is where the Sukuk growth, insurance scaling, SMBC deal flow, and green finance development are expected to contribute. The regional structure is the variable that most divides analyst opinion on CRDB. Subsidiaries contributed 5.5 percent of Group PAT in 2025, down from 6.2 percent in 2024. The medium-term target is 8.6 percent, which implies the regional operations need to begin delivering harder within the next two to three years or the contribution trajectory will work against rather than for the investment thesis. Burundi delivered improved profitability in 2025, supported by deposit mobilisation, but the operating environment there remains constrained by foreign exchange shortages and structural market frictions that are not within CRDB's control. The DRC operation is explicitly described in the report as still in its investment phase. It is consuming capital and management bandwidth while building market presence in a mining-driven economy whose scale, when the DRC's mineral wealth and infrastructure financing opportunity is considered on its merits, represents a genuinely significant long-duration opportunity. The honest assessment is that it is too early to judge. The next two to three years will be definitive. The share price move in 2025 tells its own story. CRDB closed the year at TZS 1,530, up from TZS 670 at end-2024, a 128 percent total return in a single calendar year. The market is beginning to price the regional and diversification optionality that the fundamentals have been building toward. At a market capitalisation of approximately TZS 3.996 trillion, CRDB is now the second largest company on the DSE by market cap. The head-to-head comparison the numbers support The cost-to-income divergence is the most practically significant difference between the two banks and the one most directly relevant to long-term competitive positioning. NMB at 38 percent is best-in-class for a large East African commercial bank. CRDB at 41.6 percent is improving rapidly but sits 3.6 percentage points behind. Both banks report approximately 97 to 98 percent of transactions flowing through digital and alternative channels, so the gap is not explained by different digital adoption rates. It reflects NMB's longer runway of efficiency realisation on a somewhat smaller and more homogeneous market footprint, and the additional overhead that CRDB's regional structure and investment programmes add to the cost base. NMB's Wakala advantage is the most defensible competitive asset in the Tanzania banking landscape. At 73,592 outlets, almost double CRDB's 38,883, the agent network has implications that extend beyond deposit mobilisation into brand reach, cash management infrastructure, and last-mile financial services access whose scale is not easily replicated. Agent networks require years of recruitment, training, and float management to operate reliably at quality. The gap between the two banks on this dimension is the product of roughly a decade of deliberate investment and is unlikely to close quickly. NMB's digital infrastructure investment totalled TZS 232 billion over the five-year MTP period, with TZS 52 billion deployed in 2025 alone. CRDB's 2025 digital programme was defined by the Core Banking System upgrade, a foundational but high-risk investment whose completion in 2025 creates the platform on which future digital capabilities will be built. CBS migrations are the unglamorous high-stakes work of banking technology. CRDB appears to have managed the transition well, but post-migration stabilisation extends into 2026 and the full benefit of the upgraded infrastructure will take time to realise in the operating metrics. On asset quality, NMB's 2.5 percent NPL ratio at a five-year low with consistent downward trend presents a cleaner picture than CRDB's flat 2.9 percent on a rapidly growing book. Both outperform the Tanzanian banking industry NPL average of approximately 2.8 percent. The distinction is directional: NMB's quality is improving; CRDB's is holding while the book grows at pace, which is a different kind of discipline test. What the results mean for Tanzania's economy The macro-level significance of both sets of results extends beyond the banks' own investment cases into the productive sectors they are financing and the fiscal contribution they are making. NMB disbursed TZS 27.6 trillion in cumulative loans over the 2021 to 2025 MTP period. TZS 7 trillion went to micro, small, and medium enterprises. TZS 10 trillion went to personal loans. The bank paid TZS 2.705 trillion in taxes over the same five years and has been consistently recognised by the Tanzania Revenue Authority as one of the country's leading taxpayers. The financial inclusion contribution is equally significant: a customer base that grew from 4 million to 9.9 million over five years, served primarily through the Wakala network, represents the integration of millions of Tanzanians into the formal financial system whose participation generates the savings mobilisation, credit access, and payment infrastructure that productive economic activity requires. CRDB contributed TZS 681.4 billion in taxes in 2025 alone. Its agriculture portfolio remains a core growth sector. Its Sukuk programme is opening Shariah-compliant financing to a segment of the market that has historically been underserved by conventional banking at scale. The DRC and Burundi operations, while still early, represent an outward extension of Tanzanian financial capital into neighbouring economies with long-term implications for regional trade settlement, cross-border investment facilitation, and the economic integration whose depth the EAC's institutional framework aspires to but whose practical expression requires commercial banking infrastructure of the kind CRDB is building. The combined market capitalisation of both banks now exceeds TZS 8 trillion, a substantial share of the Dar es Salaam Stock Exchange's total market cap. Their performance is increasingly used as a proxy for Tanzania's broader macroeconomic conditions, and both boards are actively engaged with international investors in a way that was not the case five years ago. That engagement is itself a development: the internationalisation of Tanzania's banking investor base deepens the DSE's liquidity and broadens the capital market infrastructure whose maturity is one of the conditions for the international financial centre ambition the Tanzania National Business Council resolved to pursue in May 2026. The risks neither bank is discussing loudly enough Deposit competition is the risk most directly relevant to NMB's profitability. NMB's CASA ratio of 84.5 percent, current and savings accounts as a share of total deposits, is a structural competitive advantage because low-cost deposits underpin net interest margin. CRDB's deposit growth of 36.5 percent was impressive, achieved in a relatively accommodative rate environment. If the Bank of Tanzania adjusts policy rates upward, cost of funds pressure will bite harder at banks with weaker CASA positions. NMB's agent network makes its CASA position more defensible than most, but not invulnerable. CRDB's foreign exchange exposure in Burundi and the DRC is a medium-term risk that is not material at current subsidiary scale but becomes increasingly relevant as the regional contribution target of 8.6 percent of Group PAT is pursued. The Burundi report specifically references foreign exchange shortages and structural market frictions. Currencies under pressure in the subsidiaries can generate translation losses that offset local-currency operating performance and create reporting volatility whose management complicates the investor relationship. Credit cycle risk applies to both banks, more acutely to CRDB given the pace of loan growth. Tanzania's private sector credit expanded strongly in 2025. Both banks have grown loan books at 20 to 32 percent annually. Credit cycles turn, and NPL ratios are a lagging indicator. The question is less whether NPLs rise and more when, and by how much, and whether the provisioning levels both banks have built are sufficient to absorb a moderate deterioration without damaging capital adequacy materially. NMB's 96 percent NPL coverage and 24.8 percent capital adequacy give it more buffer than most peers. CRDB's 17.8 percent total capital adequacy, while above minimums, leaves less room for a large simultaneous credit cycle and regional credit event. Digital security and system concentration risk is the operational risk both banks carry without adequate public discussion. With 97 to 98 percent of transactions flowing through digital channels, system availability and cybersecurity are existential operational risks rather than marginal ones. NMB reported zero data breaches and 99 percent system availability in 2025, figures that reflect genuine operational capability. CRDB completed its CBS migration in 2025, a high-risk event that appears to have been managed competently, but post-migration stabilisation extends into 2026 and the full system performance profile of the upgraded infrastructure is not yet established. The investor's assessment At face value, both banks trade at similar valuations: approximately 5.5 to 5.8 times earnings and 1.46 times book. The parity in valuation multiples does not reflect parity in the underlying businesses or in the risk profiles of the investment theses. NMB is a mature, high-return franchise with excess capital, the country's most defensible distribution asset in its Wakala network, a fresh strategic plan with clear priorities, and improving shareholder returns whose quality and consistency place it among East Africa's most compelling banking investments on a risk-adjusted basis. The risks are largely execution risks: whether Agenda 2030 can translate distribution scale into higher revenue per customer in a competitive environment, and whether the excess capital gets deployed productively rather than simply returned through a multi-year cycle of special dividends. CRDB is a faster-growing, more efficiently leveraged franchise with a regional bet still in progress, an efficiency trajectory that has delivered 14 percentage points of CIR improvement in four years, and a share price that re-rated 128 percent in a single year as the market began pricing the optionality that the strategic programme represents. The upside case is straightforward: DRC turns from capital sink to contributor within the next two to three years, SMBC delivers measurable deal flow, the Islamic banking and insurance platforms scale toward the non-funded income target, and CRDB's larger balance sheet generates higher absolute profit growth than NMB's more mature but slower-growing operation. If those bets work, the current valuation is cheap relative to the earnings power being built. If they deliver more slowly than the market has begun to price, the bank is fairly valued on its Tanzania-only operations. Neither is a sell at current prices. Both will likely outperform the DSE index over a three-year investment horizon. The choice between them is a question of investor temperament: NMB for quality, capital discipline, and predictable compounding; CRDB for growth, regional optionality, and the higher potential return that comes with the higher execution risk that regional banking in the DRC and Burundi unavoidably carries. Two record years. Two different strategies. Two different investment propositions. The numbers are close. The analysis of what they mean is not. FAQ Which bank is more profitable, NMB or CRDB? By absolute profit, NMB at TZS 760.1 billion slightly exceeds CRDB at TZS 728.6 billion in 2025. By return on equity, CRDB at 29.5 percent exceeds NMB at 27 percent, but this reflects CRDB's leaner capital structure rather than superior business economics. NMB generates its returns with a Tier 1 capital ratio of 24.7 percent against CRDB's 16.1 percent. On cost efficiency, NMB's 38 percent cost-to-income ratio is superior to CRDB's 41.6 percent and best-in-class for a large East African commercial bank. Which bank is better for investors? They suit different investor profiles. NMB offers quality, consistency, capital discipline, and a 7.3 percent dividend yield at current prices, with execution risk around whether Agenda 2030 can monetise its distribution advantage at higher revenue per customer. CRDB offers faster growth, regional optionality, and a 128 percent 2025 share price return that reflects the market beginning to price the platform being assembled, with execution risk around DRC profitability, SMBC deal flow materialisation, and Islamic banking and insurance scaling. What is NMB Agenda 2030? NMB's incoming five-year strategic plan following the completion of its 2021 to 2025 Medium-Term Plan. It prioritises deepening retail through segment-specific propositions, building a fully integrated SME ecosystem covering payments, insurance, and advisory alongside lending, expanding wholesale banking through sector-specific value-chain solutions, and selectively extending into adjacent financial services. It is the bank's plan for translating its distribution scale into higher revenue per customer. Is CRDB's DRC operation a risk or an opportunity? Currently a liability in the narrow financial sense, consuming capital and not yet profitable. Strategically, it is a long-duration bet on one of Africa's largest economies with mineral wealth and significant infrastructure financing opportunity. The honest assessment is that it is too early to judge. The next two to three years, which will either show DRC contributing to Group PAT or continuing to consume capital beyond the investment phase timeline, will be definitive for the CRDB investment thesis. How significant is CRDB's Sukuk programme? More significant than the current numbers suggest. Islamic financing assets of TZS 338.8 billion represent a small share of a TZS 13.7 trillion loan book, but the growth trajectory is steep and the market is structurally underpenetrated. Tanzania has a significant Muslim population with a near-total absence of established Islamic banking alternatives at commercial scale. If CRDB executes consistently, the Sukuk and Islamic finance platform could be a meaningful earnings contributor within five years and a durable competitive moat against later entrants. Are both banks well capitalised enough to survive a credit cycle? Yes. NMB's 24.8 percent total capital adequacy ratio and CRDB's 17.8 percent are both above BOT regulatory minimums. NMB in particular has extraordinary capital headroom. A moderate deterioration in NPLs from current levels, say NMB moving from 2.5 percent to 5 percent and CRDB from 2.9 percent to 6 percent, would increase provisioning costs materially but would not threaten either bank's solvency given their current capital positions and pre-provision income generation.
