Tanzania's USD 25 Billion Infrastructure Gap Requires a Structural Solution
Tanzania's public finances face a structural financing gap that threatens the country's ambition to achieve Tanzania Development Vision 2050 — the goal of building a USD 1 trillion economy by 2050. Nominal GDP reached approximately TZS 223 trillion (USD 87.44 billion) in 2025, up from TZS 156.6 trillion in 2024. Yet despite strong TRA collection performance, the tax-to-GDP ratio remains at only 13.1–13.3% — well below the Sub-Saharan Africa average of 16.1%.
The budget financing gap has widened to approximately TZS 20.2 trillion in FY 2024/25 (40% of expenditure) and a projected TZS 22.4 trillion in FY 2025/26 (40%). FDI inflows have stabilised at approximately USD 1.7 billion annually — a small fraction of the USD 20–30 billion annual infrastructure need. The Dar es Salaam Stock Exchange (DSE), while surging 34% in 2025 to TZS 24 trillion total market cap, still represents only approximately 10–11% of GDP. Local Government Authorities (LGAs) generate just 8% of their funding from own-source revenue.
A critical legal milestone was reached with the 2023 amendments to the PPP Act (Cap. 103), which now explicitly mandate SPV incorporation before any PPP agreement is signed, and allow the government to hold up to 25% minority equity in the SPV. Full operationalisation of this mandate would unlock a conservative USD 3.5–7.0 billion in private infrastructure investment by 2030, create tens of thousands of jobs, and materially advance the Vision 2050 target.
The Financing Gap That Makes PPP Imperative
Tanzania's economy has maintained a growth rate of 6–7% annually over the past decade. Yet macroeconomic resilience has not translated into sufficient public revenue to fund the infrastructure a growing population of 65 million requires.
Achieving Vision 2050 — a USD 1 trillion economy requiring sustained 8–10% real growth and massive capital mobilisation — demands infrastructure investment far beyond what public finance alone can provide. The convergence of a widening budget gap, modest FDI inflows, shallow capital markets, and negligible local government fiscal capacity makes structured private capital mobilisation through PPPs not just desirable but existentially necessary.

FDI, Capital Markets & LGA Revenue: The Structural Weaknesses
Three additional structural weaknesses compound the financing gap: insufficient FDI, shallow capital markets, and negligible local government fiscal capacity.
FDI inflows have stabilised around USD 1.7 billion annually in 2024–2025, driven by manufacturing, mining, and infrastructure — yet this is still only a fraction of the USD 20–30 billion annual need to sustain 8–10% growth to 2050. The DSE capital market surged an impressive 34% in 2025, closing at TZS 24 trillion total market capitalisation (USD 8.9 billion), with domestic market cap at TZS 15.6 trillion (USD 5.8 billion). Despite this growth, the DSE represents only approximately 10–11% of GDP. LGA own-source revenue remains stubbornly at 8% of LGA funding, leaving virtually no local fiscal space for infrastructure.

Why PPP Is Tanzania's Economic Bridge to Vision 2050
PPP is not merely a financing mechanism — it is an instrument for transferring operational risk, embedding private sector discipline, and aligning long-term incentives between government and investors. It allows the government to deliver infrastructure now, funded by future revenue streams (tolls, tariffs, user fees, availability payments), while private partners bear construction and operational risk.
Without scaled PPPs, Tanzania cannot close the infrastructure gap required to sustain the 8–10% real growth needed for the Vision 2050 USD 1 trillion economy target. The 2023 PPP Act amendments have provided the foundational legal architecture. The missing piece is now implementation: disciplined SPV formation, standardised documentation, political commitment to non-interference in SPV governance, and the capital market infrastructure to enable SPV bond financing on the DSE.
The 2023 amendment formally mandates that the successful private party incorporate an SPV under the Companies Act prior to executing the PPP agreement. Additionally, the public entity may hold up to 25% minority equity in the SPV, provided it can demonstrate financial capacity and risk-bearing ability. This legal reform aligns Tanzania with international best practice and removes previous ambiguity about SPV status in project structures.
(i) Low awareness and capacity on SPV concepts among procuring entities and private sector; (ii) Risk of political interference in SPV board operations; and (iii) Limited domestic experience in full project finance structuring. These gaps are the immediate priority for PPPC and the Ministry of Finance.
Low SPV Awareness
Most procuring entities across ministries and LGAs lack awareness of SPV concepts, structuring requirements, and the implications of the 2023 Act mandate. Without capacity, the legal requirement cannot be operationalised.
Political Interference Risk
Political pressure on SPV boards — appointment of politically connected directors, overriding commercial decisions — directly undermines the governance discipline that lenders require for non-recourse project finance.
No Standardised SPV Documents
Each transaction team must develop SPV Articles of Association, Shareholders' Agreements, and concession templates from scratch — increasing costs, timelines, and the risk of structurally deficient documentation.
Understanding the Special Purpose Vehicle (SPV) in PPP Context
An SPV — also termed a Special Purpose Entity (SPE) — is a legally separate, bankruptcy-remote company created specifically for a single project. Under Tanzania's 2023 PPP Act amendments, the successful private party must now incorporate an SPV under the Companies Act before signing the PPP agreement.
In PPP infrastructure finance, the SPV ring-fences the project's assets, liabilities, and cash flows from the sponsors' other businesses, enabling non-recourse project financing and simplifying risk allocation between public and private partners. The SPV sits at the centre of a web of contractual relationships: it contracts with an EPC contractor for asset delivery; with an O&M company for service provision; with lenders for debt; and with government for the concession rights to collect revenues.
