Tanzania: Interest payments (% of revenue)

Key figures

What the numbers say

In 2024, Tanzania's interest payments (% of revenue) rose 1.56 percentage points on 2023 (from 12.81% to 14.38%).

Across the 14 yearly changes before that (2010 to 2023), the average change was +0.6 percentage points and a typical year strayed about 1.18 percentage points from that (the standard deviation). This year's change was 0.8 standard deviations above that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 2.32 percentage points in 2019 and the biggest yearly fall was 2.22 percentage points in 2020. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2015 to 2024 the straight-line trend is upward, about 0.43 percentage points a year. A straight line explains 71% of the movement over 10 observed years.

What this measures

Interest payments include interest payments on government debt (including long-term bonds, long-term loans, and other debt instruments) to domestic and foreign residents. This indicator is expressed as a percentage of revenue which includes all transactions that add to the amount of economic value of a unit or sector.

Limitations: For most countries central government finance data have been consolidated into one account, but for others only budgetary central government accounts are available. Countries reporting budgetary data are noted in the country metadata. Because budgetary accounts may not include all central government units (such as social security funds), they usually provide an incomplete picture. In federal states the central government accounts provide an incomplete view of total public finance. Data on government revenue and expense are collected by the IMF through questionnaires to member countries and by the Organisation for Economic Co-operation and Development (OECD).

Regional and income-group figures are computed by the World Bank as a median.
