Indonesia: GDP deflator (base year varies by country)

Key figures

What the numbers say

In 2025, Indonesia's GDP deflator (base year varies by country) rose 2.4% on 2024 (from 171.35 to 175.41).

Across the 30 yearly changes before that (1995 to 2024), the average change was +10.4% and a typical year strayed about 13.4% from that (the standard deviation). This year's change was 0.6 standard deviations below 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 228.8% in 1965 and the biggest yearly fall was 98.7% in 1966. 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 upward, about 5.15 a year. A straight line explains 95% of the movement over 10 observed years.

Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.

A straight-line projection, tested first

Extending that straight line gives about 190.86 for 2028. We show this only because the same method, fitted on earlier years, predicted 2023 to 2025 better than "no change" would have: its average miss was 2.34, against 4.92 for assuming no change. Treat it as a continuation of the recent pattern, not a forecast of events: it cannot see a recession, a policy change or a revision to the data.
