Why sources report different numbers
The IMF, World Bank and United Nations each publish these series on their own release schedule. Where their figures differ, the reason is usually visible in the reference year rather than in the methodology.
| Source | Thailand | Indonesia |
|---|---|---|
| IMF | $580.00B2026 | $1.54T2026 |
| World Bank | $577.01B2025 | $1.45T2025 |
| United Nations | $526.52B2024 | $1.40T2024 |
These are not the same reference year. IMF publishes 2026 and United Nations publishes 2024 — each is the latest that publisher has released, on its own schedule. A figure for a year still in progress is a projection rather than an outturn. Thailand spans about 10% across 2 years; Indonesia spans about 10% across 2 years.
