The Bank of Korea reported that the Producer Price Index increased by 0.4 percent month-on-month in December 2025, rising 1.9 percent year-on-year. The Domestic Supply Price Index and Total Output Price Index also saw month-on-month increases of 0.4 percent each.
Producer prices see broad-based gains
The Producer Price Index (PPI) for December 2025 advanced by 0.4 percent month-on-month, marking a 1.9 percent increase year-on-year.
For the full year 2025, the PPI rose by 1.2 percent year-on-year.
This monthly increase was driven by several key sub-indices.
Agricultural, forestry, and marine products saw a significant rise of 3.4 percent.
Manufacturing products increased by 0.4 percent, reflecting sustained activity.
Electric power, gas, water & waste, and services both registered a more modest 0.2 percent rise.
These preliminary figures indicate a broad-based upward trend in producer prices, with various sectors contributing to the overall inflationary pressure at the producer level.
The Bank of Korea noted that all indexes are preliminary and may be revised next month.
