South Korea's producer prices remained flat in November as a rise in oil prices was offset by falling prices of farm products.  

According to the Bank of Korea on Tuesday, the producer price index for all commodities and services came to 103-point-06 for the month, almost unchanged from the previous month.

The index, a key barometer of future inflation, marked the first drop in five months in October. 

Compared to a year earlier, the index fell point-three percent, extending the on-year drop to nine consecutive months.

Prices of industrial goods gained point-two percent on-month on the rise in oil prices, while prices of agricultural, livestock and fishery products dropped one-point-six percent.
