Key Takeaways:
South Korea’s exports surged in early May, powered by an unprecedented boom in memory chip sales as the global build-out of artificial intelligence infrastructure continues to accelerate at a record pace.
"With semiconductor prices continuing to rise, South Korea's export growth is expected to remain strong in the second and third quarters," Jeong-Woo Park, an economist at Nomura Holdings, said in a note. Park added that while rising oil prices also contributed to the value of exports, the chip sector's growth reflects a substantial increase in both price and volume.
In the first 20 days of May, total exports adjusted for working days climbed 52.6% from a year earlier, according to data from the Korea Customs Service. The growth was dominated by a 202.1% explosion in semiconductor shipments. Exports of computer-related products jumped 305.5%, while shipments to China and the US rose 96.5% and 79.3%, respectively, showing widespread demand. The nation posted an $11 billion trade surplus during the period.
The stunning export figures provide a powerful tailwind for Asia’s fourth-largest economy but also create a complex challenge for its central bank. The boom is fueling inflationary pressures that may force the Bank of Korea to reconsider its policy path at its next meeting on May 28, the first to be chaired by new governor Shin Hyun Song.
The engine of the current export boom is the memory chip sector, where South Korean giants Samsung Electronics and SK Hynix are world leaders. Exports of Dynamic Random-Access Memory (DRAM), critical for processing large AI models, skyrocketed 498% year-over-year to $11.5 billion in the first 20 days of the month.
The growth reflects both volume and a massive increase in pricing. The unit price for DRAM modules jumped 432% from the prior year. The story was similar for other components essential for the AI ecosystem. NAND flash exports grew 178%, while shipments of Solid-State Drives (SSDs) used for data storage in servers climbed 452% year-over-year. The boom has generated massive profits, with Samsung recently reporting a nearly 750% jump in first-quarter operating profit. The intense environment was highlighted by recent labor negotiations at Samsung, where a potential strike was narrowly averted as workers sought a larger share of the profits.
While the chip-led export growth is a boon for the economy—which expanded 1.7% in the first quarter, its fastest pace since 2020—it comes with significant side effects. Rising global oil prices and a weaker Korean won are pushing up import costs, fanning fears of sustained inflation.
This puts the Bank of Korea in a difficult position. Even previously dovish board members have recently signaled that rate cuts are now unlikely. They cite rising inflation risks, accelerating household debt, and a rebounding property market in Seoul as key concerns. The upcoming May 28 policy meeting will be closely watched by investors to gauge how the central bank plans to balance supporting economic growth against the urgent need to contain inflation. The decision could have significant implications for the country's equity market and the valuation of its high-flying semiconductor stocks.
