South Korea's industrial production edged higher in July on support from the technology sector, but weak services and construction left overall output stagnant

Overview

The report interprets South Korea's economic activity data for July 2026. Industrial production was slightly better than expected, driven by the technology sector, but non-technology manufacturing, services consumption, and construction activity were weak, ultimately leaving overall output flat month over month; meanwhile, the composite leading index continued to indicate some improvement in forward-looking momentum.

Core views

South Korea's seasonally adjusted industrial production rose 0.2% month over month in July, posting only a modest increase after growing 6.7% in June. The result exceeded the Bloomberg consensus of -0.5% and Goldman Sachs' forecast of -1.0%, and the report characterized it as slightly stronger than expected. Goldman Sachs' Asia-Map indicator assigned the data a growth relevance score of 5 out of 5, while its surprise relative to market consensus was 0 on a scale of -5 to +5. Growth within industry was highly concentrated in the technology sector. Month-over-month technology production growth accelerated from 1.6% in June to 3.8%, contributing 0.9 percentage points to overall month-over-month industrial production momentum. The improvement was not broad-based within technology: semiconductor production growth slowed to 0.5%, while production of other electronic components, including displays and printed circuit boards, surged 20.7%, reaching its strongest momentum in a year. Gains in the technology sector were partly offset by non-technology industries, with production of automobiles, other transportation equipment, and electrical equipment falling 4.5%, 5.0%, and 2.8%, respectively. The manufacturing inventory-to-shipment ratio rebounded from 93.8 in June to 97.2, returning to its long-term average since 2015. The ratio rose across most industries, with particularly notable increases in the technology industry and in semiconductors, automobiles, metals, and metal products, indicating renewed inventory accumulation relative to shipments. Meanwhile, the manufacturing capacity utilization index edged up from 105.1 to 105.3, its highest level since July 2022; the technology industry's capacity utilization index also rebounded after four consecutive months of decline. The simultaneous recovery in inventories and improvement in capacity utilization therefore suggests that manufacturing conditions were not weakening uniformly. Domestic demand-related activity was notably weak. Seasonally adjusted services output, which accounts for more than half of South Korea's GDP, fell 1.3% month over month, reversing June's 0.9% increase and recording its largest decline since early 2022. Financial services and professional, scientific, and technical activities fell 4.8% and 2.7%, respectively, constituting the main drags. Retail sales volume fell 2.4% month over month, nearly offsetting the previous month's gain; durable goods sales declined 7.7%, while semi-durable goods continued to fall by 1.4%. The report linked these declines to the expiration of special excise tax reductions for automobiles and the end of electronics promotions. Non-durable goods consumption was broadly flat, declining only 0.1%. Investment indicators were mixed. Equipment investment rose 7.5% month over month, driven mainly by an 84.7% non-annualized month-over-month rebound in investment in other transportation equipment, such as ships and aircraft; machinery investment also increased 4.2%, although at a more moderate pace than in the previous month. By contrast, construction activity fell 1.1% after two consecutive months of growth. More forward-looking but volatile orders data weakened further: equipment orders from domestic customers fell 22.8%, and construction orders dropped 34.0%, indicating that the month's strength in actual equipment investment did not translate into a broad-based improvement in orders. On a year-over-year basis, industrial production growth, unadjusted for working days or seasonal effects, slowed from 6.0% in June to 3.6%. External demand contributed 70% of the year-over-year increase in industrial production, a higher share than in the previous month and the highest since April, indicating that year-over-year industrial growth was driven mainly by external demand, while support from domestic activity was relatively limited. Across all sectors, seasonally adjusted overall output was flat at 0.0% month over month, stagnating after a 2.4% increase in June, as declines in services and construction offset improvements in technology manufacturing and some equipment investment. However, the cyclical component of the composite leading index rose by a further 0.4 percentage points, which the report attributed to continued improvement in the terms of trade and stronger domestic demand for machinery. This presents a clearly divergent picture: current aggregate growth is subdued, but some manufacturing and forward-looking indicators continue to improve.

Analysis framework

The report first compares July industrial production with the previous reading, Goldman Sachs' forecast, and market consensus, and then breaks down the month-over-month contribution between technology and non-technology industries. It subsequently assesses manufacturing conditions using the inventory-to-shipment ratio and capacity utilization, while separately examining services, retail, equipment investment, construction, and orders. Finally, through year-over-year growth, domestic and external demand contributions, and the composite leading index, the report places the month's data within a framework of growth momentum and outlook.

Methodology notes

• (Method outside the vocabulary)

  Seasonally adjusted month-over-month growth, unadjusted year-over-year growth, and contribution decomposition

  The report uses seasonally adjusted month-over-month data to observe short-term changes, while using year-over-year data unadjusted for working days or seasonal effects to assess annual growth, and decomposes the technology sector's impact on overall industrial production by percentage-point contribution.

• Cycle and business conditions frameworkInventory cycle (Kitchin)

  Manufacturing inventory-to-shipment ratio

  The inventory-to-shipment ratio measures the level of inventories relative to shipments. The report compares the July ratio with the previous month and the long-term average since 2015 and examines changes across industries to assess manufacturing inventory conditions.

• Industry/sector analysis frameworkSupply-demand framework

  Decomposition of domestic and external demand contributions

  The report distinguishes between support from domestic and external demand for industrial production and notes that external demand accounted for 70% of the year-over-year increase in July industrial production, explaining the source of demand behind industrial growth.

  Cyclical component of the composite leading index

  The report uses the cyclical component of the composite leading index to identify the direction of future economic momentum; the indicator rose 0.4 percentage points in July, reflecting continued improvement in the terms of trade and domestic demand for machinery.

Impact & implications

The growth structure in South Korea presented by the report is relatively divergent: technology manufacturing and external demand continue to support industrial production, and equipment investment also remains on a growth trajectory, but weakness in services consumption, construction, and orders prevented overall output from expanding further. The rebound in the inventory-to-shipment ratio means that inventory changes warrant attention in addition to shipments, while improvements in capacity utilization and the composite leading index indicate that manufacturing and some forward-looking momentum have not weakened across the board.
