FX.co ★ Indonesia’s Car Sales Growth Cools in September, Year-on-Year Pace Slips to 28.1%

Indonesia’s auto market remained firmly in expansion territory in September 2026, though momentum eased compared with the previous reading. Year-on-year car sales growth came in at 28.10% for the month, down from a previously recorded 32.40% on a comparable annual basis, according to data updated on 12 October 2026.

Both the current and previous indicators reflect year-over-year changes for September, with the “actual” figure measuring the latest comparison of September 2026 sales to the same month a year earlier. The earlier 32.40% reading captured a prior assessment of annual growth for the same period. The moderation from that earlier figure suggests that, while Indonesia’s car market is still expanding at a robust double-digit pace, the rate of acceleration has begun to cool.

For market watchers and investors, the softer yet still-strong 28.10% rise may signal a maturing phase of the recent sales surge, rather than a reversal. The continued high growth level underscores sustained demand in Indonesia’s automotive sector, even as the pace of expansion adjusts from its earlier peak.
