Baseline: 27.3% (2024) | FYDP IV Target: ≥40% by 2030/31 | Gap to Close: 12.7 percentage points
FYDP IV Financial Sector Analysis | Tanzania Investment and Consultant Group Ltd
Tanzania's Deposit-to-GDP ratio stood at 27.3% in 2024, representing one of the most consequential financial depth indicators in the FYDP IV (2026/27–2030/31) reform framework. This ratio measures the value of bank deposits held in the formal financial system relative to the total size of the economy — serving as a primary proxy for savings mobilisation, financial intermediation capacity, and the depth of trust that households and enterprises place in formal financial institutions.
At 27.3%, Tanzania's deposit depth is materially below the FYDP IV target of ≥40% and significantly lags regional peers including Kenya (~43%), Rwanda (~38%), and South Africa (~70%+). This gap is not merely a statistical shortfall — it reflects a structural constraint on Tanzania's ability to finance FYDP IV's USD 183 billion investment programme, of which 70% (approximately USD 128 billion) is expected to come from the private sector.
Banks cannot extend credit substantially beyond what they mobilise in deposits. A thin deposit base translates directly into constrained credit supply, higher lending rates, and stunted private investment. This report provides a comprehensive, data-driven analysis of Tanzania's Deposit-to-GDP trajectory from 2019 to 2024, a regional benchmarking comparison, decomposition of the deposit base, structural barriers, and the policy pathway required to achieve the ≥40% FYDP IV target by 2030/31.
Tanzania must mobilise an estimated additional TZS 12–15 trillion in new deposits annually to close the 12.7 percentage point gap between the 2024 baseline (27.3%) and the FYDP IV target (≥40%) by 2030/31. At current GDP growth rates of 5.5%, this requires deposit growth to outpace GDP expansion by at least 5–7 percentage points per year over five consecutive years — an ambitious but achievable target, conditional on resolving structural barriers around financial inclusion, digital banking, and formal savings instruments.
What the Deposit-to-GDP ratio measures — and why it matters for Tanzania's FYDP IV financing
The Deposit-to-GDP ratio (also called Bank Deposits to GDP or Financial Deepening Ratio) measures the total value of deposits held at deposit-taking institutions — including commercial banks, microfinance banks, community banks, and formal savings institutions — as a percentage of the country's Gross Domestic Product (GDP). It is one of the most widely used measures of financial sector development in international finance research and policy.
| Dimension | Description |
|---|---|
| Formula | (Total Bank Deposits ÷ Nominal GDP) × 100 |
| Numerator | Total deposits at all deposit-taking institutions: demand/current, savings, time, and foreign-currency deposits |
| Denominator | Nominal GDP at current market prices (TZS) |
| What it measures | Savings mobilisation capacity; financial depth; trust in the formal banking system; intermediation potential |
| Policy significance | A higher ratio implies banks have more liabilities (deposits) to fund productive loans, bonds, and investments. A low ratio constrains credit supply regardless of lending appetite. |

Five-year deposit stock, GDP, and the ratio trajectory leading into FYDP IV
Tanzania's banking sector has recorded consistent growth in total deposits over the five-year period leading into FYDP IV, but GDP has grown at a comparably fast rate, keeping the ratio relatively flat — until 2024, when the ratio jumped notably to 27.3%, likely reflecting a broader measurement methodology that now fully incorporates digital and mobile money deposits.

With FYDP IV 40% target line — Tanzania must close a 12.7pp gap
Absolute growth 2019–2024 — deposits more than doubled but GDP kept pace
Deposit growth must consistently outpace GDP to improve the ratio — the 2021 spike illustrates the required magnitude
Total deposits more than doubled from approximately TZS 20 trillion in 2019 to TZS 42.8 trillion in 2024 — a cumulative increase of ~113% over five years. This is driven by mobile money integration, agent banking expansion, and growth in the middle-income segment.
Despite strong deposit growth in absolute terms, Tanzania's nominal GDP grew at comparable rates (driven by sustained 5%+ real growth plus inflation). The Deposit-to-GDP ratio only moved from approximately ~17–18% in 2019 to 27.3% in 2024 — a significant improvement, but far short of where Tanzania needs to be.
The 2024 ratio of 27.3% is materially higher than would be implied by the 2023 trend, suggesting either a reclassification or inclusion of digital and mobile money deposits more comprehensively within the BoT's measurement framework. This is consistent with the parallel figure of Digital Deposits at 27.2% of GDP in 2024.
FYDP IV reports two closely related but distinct indicators: (1) Deposit-to-GDP at 27.3%, and (2) Digital Deposits as % of GDP at 27.2%. The near-identical figures suggest that the BoT's deposit measurement for 2024 now fully incorporates mobile money and digital wallets within the formal deposit base — a methodological evolution that reflects Tanzania's mobile money-led financial sector growth. Much of Tanzania's deposit deepening has occurred through digital channels rather than traditional branch-based banking.
Breakdown of Tanzania's TZS 42.8 trillion deposit stock — who holds deposits and in what form
Understanding who holds deposits and in what form is essential for identifying where deposit growth can be accelerated. Tanzania's deposit base in 2024 is composed of several distinct segments, each with different growth drivers and policy levers.
| Deposit Category | Estimated Value (TZS Trillion) | Share of Total (%) | Key Drivers & Notes |
|---|---|---|---|
| Demand / Current Account Deposits | ~14.5 | ~34% | Corporate & government accounts; high turnover; large banks dominant |
| Savings Deposits | ~10.7 | ~25% | Household savings; growing middle class; mobile savings accounts (M-Pawa, Timiza) |
| Time / Fixed Deposits | ~7.3 | ~17% | Institutional & corporate; pensions; short-term (3–12 months); limited long-term deposits |
| Foreign Currency Deposits | ~8.6 | ~20% | Business & diaspora; FX risk sensitivity; material and growing segment |
| Mobile Money / E-Wallet Deposits (formalised) | ~1.7 | ~4% | Float held in banks from mobile operators (Vodacom M-Pesa, Airtel Money, Tigo Pesa, Halotel); the bulk of the ~68M subscription value is transactional not depositional |
| TOTAL | ~42.8 | 100% | Source: BoT Banking Supervision Annual Report 2024 |

Total deposit base: TZS 42.8 trillion
~35 million adults — who holds deposits and who remains excluded
| Segment | Est. Adults | Share (%) | Deposit Behaviour & Potential |
|---|---|---|---|
| Formal bank account holders | ~9.5M | ~27% | Core deposit base; growing but concentrated in urban / formal employment |
| Mobile money only (no bank account) | ~12M | ~34% | High-frequency small transactions; minimal savings; key expansion frontier for deposit mobilisation |
| SACCO / MFI members only | ~4M | ~11% | Informal savings; some formalised; growing rural segment |
| Fully excluded (no formal or digital access) | ~9.5M | ~27% | Rural, elderly, women, subsistence farmers; structural barriers: distance, documentation, income informality |
| TOTAL Adults | ~35M | 100% | Source: BoT, FinScope Tanzania 2023, FSDT, World Bank Global Findex |
The fully excluded 27% and the mobile-only 34% represent Tanzania's two largest deposit mobilisation frontiers. Unlocking even 30–40% of these populations into formal savings products could contribute an additional 4–6 percentage points to the Deposit-to-GDP ratio over five years.
How Tanzania compares with East African peers and the lessons available from Kenya and Rwanda
Tanzania's 27.3% Deposit-to-GDP ratio positions it among the lower-performing EAC member states on financial depth, despite Tanzania being the second-largest economy in East Africa. The benchmarking data below uses the most recent available figures for each country (2022–2024).

Deposit-to-GDP · Private Credit-to-GDP · Financial Inclusion (normalised to 100)
Tanzania's 27.3% is approximately 16 percentage points below Kenya and 11 percentage points below Rwanda — two countries whose financial sectors have benefited from sustained digital financial services investment and regulatory innovation.
The gap between Tanzania's deposit depth (27.3%) and its private credit depth (15–17%) is consistent and expected: banks can only lend approximately 60–70 cents for every TZS 1 of deposits after holding reserves and liquidity buffers. A low deposit base directly causes a low credit base.
Rwanda increased its deposit-to-GDP ratio from below 15% in 2010 to approximately 38% by 2023 — a 23+ percentage point gain over 13 years — through aggressive financial inclusion, mobile money, and SACCO formalisation policies. Tanzania's path to 40% mirrors this playbook.
Kenya's ~43% reflects the deep integration of M-Pesa into the deposit ecosystem, with mobile money balances being swept into commercial bank accounts — a model Tanzania has begun to replicate but has not yet scaled to equivalent depth.
