South Korea's import and export prices both rose last month on the won’s depreciation against the U.S. dollar and a rise in global oil prices. 

According to data from the Bank of Korea(BOK) on Tuesday, the country's export price index reached 133-point-81 in July, rising zero-point-seven percent from a month earlier.

The BOK attributed the rise to the depreciation of the local currency, which weakened zero-point-two percent against the U.S. dollar last month.

The import price index also rose zero-point-four percent on-month to hit 143-point-two in July. 

Import prices grew for four straight months since January before falling in May, but rebounded in June and grew for the second consecutive month in July. 

The increase is mainly due to a jump in oil prices, with the price of Dubai Crude, South Korea's benchmark, rising one-point-five percent month-on-month to 83 dollars and 38 cents per barrel in July.
