South Korea’s producer prices accelerated in August 2026, with the Producer Price Index (PPI) rising 7.9% year-over-year, up from a 7.7% gain in July 2026. The latest figures, updated on 17 September 2026, point to a modest pick-up in cost pressures at the wholesale level.
The current reading means that prices received by producers in August 2026 were 7.9% higher than in August 2025, while the previous month’s data showed a 7.7% increase compared with July 2025. This year-over-year comparison framework highlights a slight strengthening in underlying producer inflation momentum heading into late Q3 2026.
