South Korea's producer prices rose point-seven percent on-month in December due to rises in oil prices and farm products.

According to the Bank of Korea Thursday, the producer price index for all commodities and services stood at 103-point-78 in December.

Considering that the index, a key barometer of future inflation, gained only point-one percent in November, December's increase is quite significant. 

From a year earlier, the index inched up point-one percent to post the first on-year gain in nine months.  

Prices of agricultural, livestock and fishery products rose two-point-three percent on-month in December, mainly due to the rise in prices of farm products, which jumped five-point-nine percent. 

Prices of industrial goods gained one percent on-month on the rise of oil prices.

Prices of the country's benchmark Dubai crude marked 49 U.S. dollars and 84 cents per barrel on average in December, up 14-point-eight percent from the previous month.
