South Korea's September exports hit a record high, led by a 262.8% surge in semiconductor shipments. The gains are concentrated in high-value AI server memory, while commodity DRAM export growth lags behind products with rising prices.

Key Facts

South Korea's semiconductor exports rose 262.8% year-on-year in September, according to Ministry of Trade, Industry and Energy data.
Computer exports jumped 435.3% year-on-year in September, driven by demand for AI infrastructure.
The fixed price for DDR5 16Gb memory reached $48 in September, rising every month since May.
Commodity DRAM export volumes rose in September, but unit prices held at the previous month's level.
Shinhan Investment Corp said semiconductors approached half of South Korea's total exports in September.

Export Surge

South Korea's September exports and trade surplus both posted the largest monthly figures on record, with semiconductors contributing heavily. Semiconductor exports jumped 262.8% from a year earlier, while other items excluding semiconductors rose 23%. Export value rose even though the Chuseok holiday shifted into September, reducing the number of working days. The Ministry of Trade, Industry and Energy said rising memory demand boosted export volumes and kept fixed prices on an uptrend.

AI Demand Concentration

Demand from AI infrastructure investment is concentrating on high-capacity server memory and enterprise SSDs. Computer exports in September rose 435.3% from a year earlier, which the ministry attributed to the spread of agentic AI and rising demand for AI infrastructure. By region, semiconductors posted the largest export increase to the United States, China, and ASEAN. Shinhan Investment Corp said rising memory prices and expanding server demand are supporting exports despite the burden of a stronger won.

Product-Level Divergence

Hanwha Investment & Securities said high-value, high-capacity memory saw both export unit prices and volumes improve in September from the previous month. Commodity DRAM saw volumes rise in the same month, while unit prices held at the previous month's level. In September overall exports, export unit prices rose 44.1% from a year earlier, outpacing export volume growth of 27.3%. The ministry said the fixed price for DDR5 16Gb rose every month from May and reached $48 in September, while NAND flash 128Gb rose in June and July, then its gains narrowed, leaving it up just $0.
