The country’s export and import prices both increased for the fourth consecutive month in April on the back of the Korean won’s depreciation against the U.S. dollar and rising global oil prices. 

According to data released by the Bank of Korea(BOK) on Tuesday, the country's export price index marked 132-point-17 last month, up four-point-one percent from March to climb for the fourth straight month.

The BOK said that the rise is attributed to the depreciation of the Korean currency, which in April weakened two-point-eight percent month-on-month and three-point-six percent year-on-year against the dollar.  

The import price index also gained three-point-nine percent from March to stand at 143-point-68 last month.

A rise in global oil prices drove the increase in the index, with the price of Dubai Crude, South Korea's benchmark, climbing five-point-nine percent month-on-month in April.
