On April 9, 2026, the South Korean exchange-traded fund (ETF) market made headlines as FnGuide, a leading domestic index provider, announced that the total net asset value (NAV) of ETFs tracking its indices had soared past 55 trillion Korean won. This milestone, reported by Asia Economy, highlights the rapid growth and diversification of Korea’s ETF industry, fueled by a confluence of sectoral booms, global market shifts, and investor appetite for both innovation and stability.
At the heart of this surge is Mirae Asset Global Investments’ ‘TIGER Semiconductor TOP10’ ETF, a flagship product tracking FnGuide’s semiconductor index. This ETF not only surpassed 10 trillion won in net assets—an unprecedented feat for a theme-based equity ETF in Korea—but also secured its spot as the third-largest ETF by assets under management (AUM) in the entire market. The fund’s success reflects investors’ confidence in the semiconductor and artificial intelligence (AI) sectors, which have recently outperformed amid a global race to build AI infrastructure and expand chip production capacity.
But the story doesn’t end with semiconductors. Investors are also chasing opportunities in defense and shipbuilding, sectors that have gained momentum as geopolitical tensions, such as the ongoing US-Iran standoff and the protracted Russia-Ukraine war, drive up military spending and demand for advanced weaponry. According to FnGuide representatives, "Investors are clearly shifting towards domestic ETFs focused on semiconductor, defense, and shipbuilding sectors with high export ratios, expecting hedging benefits against won depreciation or asset value protection through dividends." The combination of rising international oil prices, a strengthening US dollar, and a weakening Korean won has only heightened uncertainty, prompting a flight to ETFs that can offer both growth and protection.
Meanwhile, a different kind of ETF story has been unfolding on the KOSDAQ, Korea’s tech-heavy junior bourse. Last month, the country saw the launch of its first active ETFs on KOSDAQ: the KoAct KOSDAQ Active ETF and the TIME KOSDAQ Active ETF. These funds, unlike traditional passive ETFs that simply track an index, are managed with the goal of outperforming the market by selectively investing in a narrower basket of stocks. The novelty and promise of these products attracted over 1 trillion won in net inflows from individual investors within just one month, as reported by Chosun Ilbo.
Yet, the initial results were sobering. By April 8, 2026, the KoAct ETF had declined by 13.5% and the TIME ETF by 15.3%, compared to the KOSDAQ index’s 1.13% drop and passive KOSDAQ150 ETFs’ more modest 5% fall. The concentrated nature of their portfolios—74 stocks for TIME, 85 for KoAct—left them more exposed to market shocks, including a sharp rise in oil prices triggered by Middle East turmoil and a steep drop in major biotech stocks like Samchundang Pharmaceutical. The top five holdings in each ETF fared poorly, with average returns of -8.93% for KoAct and -14.96% for TIME since launch.
Industry experts, however, caution against writing off active ETFs altogether. Their flexibility in stock selection, unconstrained by index composition, means they can potentially deliver outsized returns in bull markets. As one analyst told Chosun Ilbo, "In volatile conditions like these, the gap between winners and losers can widen significantly depending on the manager’s strategy." The debut of active ETFs on KOSDAQ, despite their rocky start, signals a maturing market where investors are seeking more tailored solutions.
Defense-themed ETFs have also grabbed the spotlight, both at home and abroad. The PLUS K Defense ETF, managed by Hanwha Asset Management, was the top-performing ETF in Korea last year, boasting a staggering 177% return and swelling to 1.8225 trillion won in net assets by early April 2026. Its American counterpart, listed as the PLUS Korea Defense Industry Index ETF (KDEF) in February 2025, has already amassed 170 million USD (about 2.58 trillion won) in assets, with the pace of growth quickening this year, according to Central Daily.
The appeal of these ETFs lies in the global competitiveness of Korean defense companies, which are lauded for their short delivery times, on-time and on-budget performance, and cost-effectiveness. Their products have been battle-tested in recent conflicts, including the Russia-Ukraine and Iran wars. Hanwha’s vice president, often dubbed the ‘father of K Defense ETF’, told Central Daily, "The current geopolitical tensions are reminiscent of a ‘Cold War 2.0’ that could last 30 to 40 years." He predicts that even if current wars end, the lingering threat will keep military budgets elevated, especially in the Middle East and Europe, as countries respond to new regional security challenges and the ongoing US-China rivalry. The executive’s conviction is so strong that he holds about 50% of his own individual retirement pension in the PLUS K Defense ETF.
The ETF boom hasn’t been confined to Korea’s borders. On April 8, 2026 (US time), Yahoo Finance reported that the iShares MSCI Korea ETF, traded on the New York Stock Exchange, surged 10.13% to 140.07 points—the highest increase among all country ETFs. For comparison, Chile’s ETF rose 7%, while Taiwan, India, and Japan saw gains of about 5%. The KOSPI, Korea’s main stock index, also jumped 6.87% that day, outpacing major global indices; the Dow Jones rose 2.85%, S&P 500 climbed 2.51%, and Nasdaq gained 2.80%. European markets rallied, too, but none matched Korea’s momentum.
This extraordinary performance cements Korea’s place as the world’s best-performing major stock market, at least for now. The surge in Korean ETFs—both domestically and on global exchanges—speaks to the country’s growing influence in sectors that are shaping the future: semiconductors, defense, AI, and beyond.
Of course, the ETF landscape is not without its risks. Volatility, sector-specific shocks, and the unpredictability of global events can turn winners into losers overnight. But for investors with an eye on the long term, the combination of innovation, resilience, and global demand that characterizes Korea’s leading sectors suggests that the country’s ETF market is more than just a flash in the pan. Whether in Seoul or New York, the world is watching—and, increasingly, investing.
