South Korea's exports rose 5.4 percent on-year in June on solid demand for chips and petroleum products, but the country extended its trade deficit for the third consecutive month due to high global energy prices, data showed Friday.

During the first six months of this year, the country saw exports reach an all-time half-year high, but high-flying energy prices sent the trade deficit to the highest figure for any first-half period, according to the data compiled by the Ministry of Trade, Industry and Energy.

Last month, outbound shipments stood at $57.73 billion, up from $54.78 billion a year earlier.

It is the highest tally for any June since the ministry began compiling related data in 1956. The previous record was set a year earlier.

June marked the 20th consecutive month that the country's exports have logged an on-year expansion. But the growth slowed down to end 15 straight months of double-digit growth.

The slowdown came as the country had fewer working days in June due to holidays for the June 1 local elections and Memorial Day on June 6. This year's number of 22 days is fewer than the 24 days for the same month last year.

Exports were also affected by domestic logistics disruptions over a truckers' strike in early June, according to officials.

Imports jumped 19.4 percent on-year to $60.2 billion in June on soaring global energy prices, leading the country to post a trade deficit of $2.47 billion, the data showed. The country has posted a trade deficit since April.

Dubai crude, South Korea's benchmark, rose to $113.27 per barrel in June on average from $71.6 a year earlier.

South Korea depends on imports for most of its energy needs, and the country's energy imports spiked around 63.7 percent on-year to $13.73 billion in June, according to the ministry.

During the first six months of this year, South Korea saw exports grow 15.6 percent to an all-time half-year high of $350.3 billion.

Imports advanced 26.2 percent on-year to $360.6 billion due mainly to high global energy costs and the surge in raw materials prices.

The country, accordingly, logged a trade deficit of $10.3 billion in the January-June period, which was the highest figure for any first-half period, the data showed. (Yonhap)
