Import and export prices fell by the widest margin since January as the value of the local currency rose against the U.S. dollar.
 
The Bank of Korea said Tuesday that the export price index was 82-point-12 in October, down three-point-five percent on month.
 
It was the biggest fall in nine months since export prices fell four-point-three percent in January.
 
The index was also at its lowest in 28 years and 10 months since December 1986.
 
The central bank attributed the sharp fall to a three-point-one percent decline in the foreign exchange rate in October from the previous month.
 
The import price index was 78-point-42 last month, down three percent from September, marking the biggest fall since January.
