South Korea September output jumps 3 percent in triple rebound

South Korea's industrial production rose 3.0 percent in September from August, its biggest monthly increase in 15 years and six months, with retail sales up 3.6 percent and facility investment up 5.3 percent in the first simultaneous rise in three months.

Why it matters: The triple rebound reverses August's simultaneous decline in all three gauges and, coming a day after third quarter GDP beat the central bank's forecast, strengthens the picture of a chip led expansion heading into the Bank of Korea's next decision.

South Korea’s factories, shops and boardrooms all expanded in September. The National Data Agency reported all-industry production up 3.0 percent from August, the largest monthly increase since March 2011, alongside retail sales up 3.6 percent and facility investment up 5.3 percent, Yonhap News Agency reported. Mining and manufacturing output jumped 9.0 percent, led by semiconductors, up 19.2 percent, and automobiles, up 39.9 percent as the end of a strike and of summer holidays lifted factory operating rates after August’s sharp fall.

Retail’s 3.6 percent rise was its biggest in three years and seven months, with durable goods such as cars up 4.4 percent, food and beverages up 4.2 percent and clothing up 0.6 percent, while facility investment was led by transport equipment, up 7.4 percent, and machinery, up 4.7 percent.
