Hyundai Motor strike rattles industrial activity in Ulsan

Industrial activity in Ulsan, South Korea's industrial heartland, contracted sharply in August as a drop in working days at Hyundai Motor — the city's anchor employer — dragged down automobile production and confirmed the auto sector's outsized influence on the regional economy.

According to the "August 2026 Ulsan Metropolitan City Industrial Activity Trends" report released Thursday by the Donnam Regional Data Service, automobile production in Ulsan fell 53.9 percent from a year earlier, pulling the city's overall mining and manufacturing output index down 22.2 percent. The declines far outpaced the national figures for August, which showed a 24.8 percent drop in auto production and a 4.8 percent decline in the mining and manufacturing output index.

Ulsan's August production trends showed output down 22.2 percent, shipments down 17.3 percent and inventories up 1.8 percent compared with the same month a year ago. Production and shipments fell while stockpiles grew.

Within mining and manufacturing, machinery and equipment (up 27.0 percent) and food products (up 13.4 percent) posted gains, but automobiles (down 53.9 percent), rubber and plastics (down 32.8 percent), electrical equipment (down 28.2 percent) and fabricated metals (down 24.9 percent) led the decline. The slump in finished-vehicle output froze demand for related products such as tires, dealing a cascading blow to the rubber and plastics and fabricated metals sectors.

On the shipments side, machinery and equipment (up 19.6 percent), paper products (up 10.2 percent) and food products (up 9.4 percent) increased, while automobiles (down 49.1 percent), electricity and gas (down 24.3 percent) and electrical equipment (down 20.4 percent) recorded the steepest drops. Even in July, when the strike began, automobile production was already down 5.5 percent and shipments down 6.9 percent year on year.

In inventories, automobiles fell 5.0 percent, while machinery and equipment rose 39.9 percent and primary metals climbed 26.6 percent, reflecting sluggish sales of parts and components tied to the strike.

"The summer shutdown and the strike overlapped, significantly reducing the number of working days and causing a chain reaction that suppressed production activity across auto-related industries," said Lee Ji-hyeon, a team leader in the economic research division of the Donnam Regional Data Service.

The Hyundai Motor union launched its wage negotiations this year with a two-hour partial strike on July 13 and carried out a total of 60 hours of strike action over 18 days through Aug. 21, based on union membership. Because morning and afternoon shifts struck separately, however, the actual production-line shutdown amounted to 120 hours.

Industry estimates put the cumulative production loss from the strike at 55,200 vehicles — based on an output rate of 460 units per hour — with sales losses exceeding 2.3 trillion won ($1.7 billion).

Consumer trends also weakened, with the hypermarket sales index falling 2.4 percent year on year, dragging the overall figure down 1.0 percent. Home appliances, leisure and hobby goods, food and beverages, and cosmetics all declined. Investment trends, however, offered a brighter note: construction orders reached 216.1 billion won, up 16.5 percent from 185.5 billion won in the same month a year earlier.
