Oman: Military expenditure (% of GDP)

Key figures

What the numbers say

In 2025, Oman's military expenditure (% of GDP) rose 0.09 percentage points on 2024 (from 5.59% to 5.68%).

Across the 30 yearly changes before that (1995 to 2024), the average change was −0.21 percentage points and a typical year strayed about 1.18 percentage points from that (the standard deviation). This year's change was 0.3 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 9.43 percentage points in 1975 and the biggest yearly fall was 5.31 percentage points in 1979. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2016 to 2025 the straight-line trend is downward, about 0.52 percentage points a year. A straight line explains 84% of the movement over 10 observed years.

What this measures

Military expenditure by country as percentage of gross domestic product

Limitations: SIPRI strives to compile reliable, consistent military expenditure data by assessing multiple sources, but accuracy depends on the quality and transparency of those sources. Challenges arise from two key issues: whether reported figures reflect actual spending and how closely they match SIPRI’s definition. While data is generally accurate in developed and many developing countries, weak governance, corruption, and secret transfers in others can lead to major discrepancies. SIPRI sometimes makes estimates, when sources conflict or lack coverage, introducing uncertainty, especially for countries like China or the UAE.

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