South Korea's AI chip windfall masks deepening economic divide

Semiconductor surge creates two-speed economy

South Korea's economy is posting numbers not seen in decades, driven almost entirely by surging demand for AI memory chips. The country's nominal GDP growth hit 17.1 percent in the first quarter of 2026—the highest rate since 2002—and is expected to exceed double digits for the full year. Yet the nation's chief economic policymaker has issued an unusually blunt warning: the boom may be masking serious structural problems.

Kim Yong-beom, head of South Korea's Presidential Policy Office, wrote in a weekend social media post that while headline indicators look strong, "a corner of my heart feels heavy." His concern centers on how narrowly the gains are distributed. Samsung Electronics and SK Hynix, the two memory chip giants supplying AI systems worldwide, have seen profits skyrocket. Their stocks now account for more than half the market capitalization of South Korea's benchmark Kospi index, which has surged over 200 percent in the past year.

Meanwhile, local shopping districts are filling with shuttered storefronts. Small businesses, retail, construction, and services sectors are struggling to keep pace. The current account surplus reached $102.6 billion in the first four months of 2026—more than four times the year-earlier figure—yet the won remains weak as foreign investors repatriate profits.

Why it matters

South Korea's experience illustrates a challenge facing economies worldwide as AI drives concentrated wealth creation in specific technology sectors. When growth becomes this lopsided, traditional policy tools—interest rates, fiscal stimulus, even headline GDP figures—can mislead decision-makers about underlying economic health. The risk is that policymakers celebrate aggregate numbers while missing deterioration in sectors that employ the majority of workers, potentially allowing inequality and asset bubbles to build unchecked.

Economists call for separate tracking

Several economists are now urging authorities to publish dual economic indicators—one including semiconductors and one excluding them—to give a clearer picture of conditions beyond the chip sector. Kim Gwang-suk of Hanyang University noted that semiconductor exports jumped 154 percent year-over-year in the first five months of 2026, driving overall export growth of 43 percent. Strip out chips, however, and many other export categories have weakened sharply.

Kim Dae-jong of Sejong University called the concentration in semiconductors "the most serious challenge facing South Korea's economy." He warned that the semiconductor upcycle won't last indefinitely and urged policymakers to strengthen employment-generating sectors including construction and distribution. With only about 55 percent of households in the Seoul metropolitan area owning homes, he also called for increased housing supply rather than demand suppression.

Property speculation concerns loom

Kim Yong-beom identified late 2026 and early 2027 as a critical window when bonus payments, wage increases, and export earnings from the chip boom will flow more broadly through the economy. Historical patterns suggest this liquidity could flood into real estate, driving prices higher and concentrating wealth further.

The policy chief acknowledged that raising interest rates to curb speculation would disproportionately hurt small-business owners and low-income households who rely on debt. Similarly, property taxes alone are unlikely to contain housing price increases in Seoul and surrounding areas. Hur Jung of Sogang University argued that authorities should accelerate redevelopment projects and reinvest technology-sector tax revenues into research, infrastructure, and cultivating new high-growth industries.

"If wealth generated by the semiconductor sector is absorbed into real estate and concentrated among a small segment of society, this boom will not last long," Kim Yong-beom warned. The alternative, he suggested, is directing rising profits toward young people, vulnerable groups, and future industries—a path that could help South Korea "escape the tunnel of low growth it has long been unable to leave."
