Producer prices in South Korea fell four percent last year from a year earlier.
 
The Bank of Korea(BOK) said Tuesday that the producer price index was 100-point-95 in 2015, down four percent from the previous year.
 
It was the steepest on-year decline since the central bank began compiling related data in 1990.
 
December’s producer price index at 99-point-06 was also the lowest monthly figure since April 2010.

The BOK said the decrease in international prices of raw materials including oil led the fall in producer prices for particularly petrochemical and metal products.
