South Korea’s Chip Stockpile Swells in Warning Sign for Exports

South Korea’s semiconductor stockpiles expanded at the fastest pace in more than six years, adding to concern about the outlook for exports that drive the country’s economic growth.

Nationwide inventory soared 79.8% in June from a year earlier, the statistics office said Friday, up from a 53.8% jump in May. At the same time, both production and shipments decelerated, suggesting a slowdown in the nation’s most profitable industry.
