South Korea's import prices hit a four-year high last month due to a rise in crude oil prices.

According to the data by the Bank of Korea on Tuesday, the import price index rose one-point-five percent to 92-point-06 in October from the previous month. 

It’s the highest figure since September 2014, when it stood at 93-point-03, and marks the second consecutive on-month increase.

The central bank attributed the rise to a gain in international oil prices, pointing out that the average price of Dubai crude, South Korea's benchmark, rose two-point-eight percent on-month to 79-point-39 dollars per barrel last month.
