Investment activity in Tanzania has expanded sharply over the past five years, with the number of registered projects more than tripling and total capital inflows almost tripling, according to data from the Tanzania Investment and Special Economic Zones Authority (Tiseza).
Tiseza data shows Tanzania registered 915 investment projects in 2025, up from 252 projects in 2021.
Over the same period, the total value of approved investment capital rose to $10.95 billion in 2025 from $3.7 billion four years earlier.
The data points to a rapid acceleration in investment approvals from 2023, when the number of projects jumped to 526 from 293 in 2022, while capital inflows rose to $5.7 billion from $4.5 billion.
Growth peaked in 2024, with project registrations surging to 901 and total investment value climbing to $9.3 billion, marking the largest single-year increase in both metrics during the period under review.
While the number of projects rose only marginally between 2024 and 2025, investment value increased by $1.65 billion, suggesting a shift towards fewer but larger, more capital-intensive projects.
Tanzania has in recent years sought to attract investment through regulatory reforms, expansion of special economic zones and efforts to streamline business approvals, particularly in manufacturing, energy, mining and agribusiness.
The widening gap between project numbers and capital value indicates growing investor appetite for large-scale ventures, though implementation and execution remain key to translating approvals into jobs and economic growth.
Tiseza did not immediately provide a sectoral breakdown of the 2025 investments.
The investment surge comes as Tanzania positions itself as a regional investment hub in East Africa, competing with peers for foreign capital amid global economic uncertainty.
