As international oil prices fell, the inflation rate for petroleum products was flat. It sharply reduced the pace of increase from a month earlier (6.1%). Last month, international oil prices averaged $61.7 per barrel based on Dubai crude, down $18.7 from January last year ($80.4).

Prices of agricultural, livestock and fishery products rose 2.6%. The pace of increase slowed from a month earlier (4.1%), marking the lowest increase in four months since September last year. Lee Du-won, Deputy Director General for economic trend statistics at the Ministry of Data and Statistics (MODS), said, "With increased shipments of tangerines and higher imports of cherries, the pace of price increases for fruit has slowed," and "For vegetables, increased cultivation areas for napa cabbage and radishes boosted shipments, widening the decline in prices."

However, some items saw sharp price increases, including rice (18.3%), apples (10.8%), lettuce (27.1%), yellow croaker (21%) and mackerel (11.7%). Due to the spread of highly pathogenic avian influenza (AI), egg prices also recorded a high rate of increase (6.8%). In particular, fishery products and livestock products rose 5.9% and 4.1%, respectively, amplifying the overall increase in agricultural, livestock and fishery prices. The Deputy Director General said, "With price measures for Lunar New Year essentials in place, prices should stabilize in February."

The service price inflation rate was 2.3%. The Deputy Director General said, "Outpatient and inpatient medical fees increased due to some medical fee hikes at the start of the year, and sewerage fees were raised in Seoul and Busan."
