South Korea Posts Record Exports on AI Chip Boom

South Korea's exports expanded 53.2% year-on-year in May to a record $87.75 billion, according to preliminary trade ministry data reported by Reuters and reflected in Dow Jones coverage. Semiconductor exports rose 169.4% to $37.16 billion, setting a new monthly high, the trade data showed and Chosun cited the ministry as saying. Imports increased 20.8% to $60.80 billion, producing a trade surplus of $26.95 billion, per Dow Jones. The benchmark Kospi index rose more than 2% on the day to a record high, and has gained over 100% year-to-date, Reuters and AsiaOne reported.

The Ministry of Trade, Industry and Resources figures reported by Chosun show memory-chip price inflation is a major proximate factor: the fixed price of DDR5 16-gigabit rose from $4.80 in May last year to $37.50 this May, a 682% increase, while NAND 128-gigabit moved from $2.92 to $26.50, an 807% increase. Chosun and MarketScreener both reported that other IT categories also posted strong gains, with computer exports up 290.7% and wireless and display exports rising, while vehicle shipments fell about 5.9% and steel fell 2.1%, according to the trade release and Dow Jones reporting.

countries with leading memory-fabrication capacity tend to see outsized trade and earnings effects when AI infrastructure demand drives memory price spikes. Memory price moves produce pronounced swings in export value because a relatively small change in unit price can translate into large revenue shifts for large-volume producers. Observed patterns from prior memory cycles show similar impacts on trade balances, corporate profits, and equity indices during tight supply or rapid demand shifts.

AsiaOne cited economist Stephen Lee of Meritz Securities saying the pace of export growth was "truly an unprecedented pace," and Lee is quoted forecasting stronger momentum and a higher 2026 GDP projection. Reuters and Dow Jones noted the Bank of Korea raised its 2026 growth forecast recently to 2.6% from 2.0%, citing improved trade performance and stronger-than-expected quarterly growth driven by chip exports.

For practitioners and market observers, pay attention to these indicators that appear in the trade data and coverage:

• •memory price indices and contract prices for DDR5 and NAND, as reported by industry price trackers and the ministry figures cited by Chosun;
• •hyperscaler and cloud capex announcements, which influence server demand for memory and SSDs;
• •shipment destinations and volumes, notably large year-on-year rises to the U.S. (+59.1%) and China (+80.9%) reported by Dow Jones;
• •equity performance of major manufacturers such as Samsung Electronics and SK Hynix, which MarketScreener and Reuters identified as leading the Kospi rally.

For practitioners: rapidly rising memory prices change procurement and forecasting assumptions for infrastructure teams and hardware buyers, and they increase the importance of short-term price monitoring and inventory planning. Firms building large-scale AI training or inference capacity will need to track both capex signals from cloud providers and spot/contract memory markets to time purchases effectively.

Reporting across Reuters, MarketScreener, AsiaOne, and Chosun also highlights headwinds: logistics disruptions tied to the Middle East conflict and higher raw-material costs are cited as pressure points for non-chip sectors, and automobile exports contracted during the month. MarketScreener noted that while chip-led export growth appears strong now, many analysts still caution that broader economic headwinds could eventually temper infrastructure spending.
