The Bank of Korea has taken the unusual step of issuing a risk warning over so-called “Samsung-SK Hynix leveraged ETFs,” stating that these products are amplifying market concentration and volatility in South Korea’s stock market, where investment is heavily skewed toward the two semiconductor giants. The warning comes just ten days after the central bank’s Financial Stability Report assessed the market impact as “limited,” a sharp about-face that is expected to lend momentum to regulatory scrutiny by financial authorities.<\/p>\n
In a written response submitted to People Power Party lawmaker Park Sung-hoon on July 5, the Bank of Korea stated: “With Samsung Electronics and SK Hynix now accounting for more than half of the stock market in terms of market capitalization and trading volume, the expansion of single-stock leveraged ETF investments could further intensify this concentration.”<\/p>\n
The central bank noted that “the domestic stock market has seen a significant increase in concentration toward a few companies, driven in part by strong earnings in the semiconductor sector,” and warned that “single-stock leveraged ETFs can deepen one-sided trading concentration as inflows and outflows expand in response to changes in the business environment or market expectations.”<\/p>\n
Indeed, the combined market capitalization share of Samsung Electronics and SK Hynix on the KOSPI market has surged from 36.1% at the end of last year to 55.3% as of June 24. Their share of trading value has similarly skyrocketed from 27.9% to 63.5% over the same period, entrenching a structure in which the two stocks effectively dictate KOSPI index movements and market supply-demand dynamics.<\/p>\n
The Bank of Korea expressed particular concern that individual investors could see losses snowball during a market downturn. “In the event of a stock price correction, not only could individual investor losses expand, but increased redemptions or position rebalancing could act as factors that amplify stock price volatility,” the bank explained. It added that “as leveraged ETF investments grow, the potential for amplified stock price volatility persists through daily rebalancing and spot-futures arbitrage trading.”<\/p>\n
Single-stock leveraged ETFs are products designed to deliver twice the daily return of underlying assets such as Samsung Electronics and SK Hynix. Asset managers perform “daily rebalancing” near each day’s market close, buying or selling additional shares and stock futures to maintain the target leverage ratio. The structural problem is that this process amplifies volatility: on up days, additional buying extends gains; on down days, additional selling deepens losses.<\/p>\n
The Bank of Korea also warned that risks could escalate further when so-called “debt-fueled investing” combines with leveraged ETFs. According to the Korea Financial Investment Association, the average daily balance of margin loans reached 35.94 trillion won (approximately $23.5 billion) in the second quarter (April\u2013June), up 15.9% from the first quarter’s 30.13 trillion won and marking the highest quarterly level on record.<\/p>\n
The central bank’s latest warning stands in stark contrast to the tone of its Financial Stability Report released on June 24. At that time, the Bank of Korea offered a positive outlook on single-stock leveraged ETFs, stating they would “contribute to preventing domestic investment capital from flowing overseas and expanding foreign capital inflows by resolving regulatory imbalances with overseas-listed ETFs.” It also expressed expectations that “demand for high-risk, high-return exposure to domestic blue-chip stocks would be absorbed, leading to a broader base for the domestic stock market and enhanced price discovery functions.” Yet within just ten days, the bank has dramatically escalated its warning level, effectively retracting its previous stance.<\/p>\n
Similar concerns are emerging from financial markets and academia. Lee Hyo-seob, senior research fellow at the Korea Capital Market Institute, said: “While I don’t view single-stock leveraged ETFs as the primary driver of volatility in the Korean stock market, they may have amplified volatility stemming from domestic and external factors.” Lee added that “semiconductor stocks have risen sharply in a short period and could certainly decline,” warning that “individual investors could compound their losses by averaging down when stock prices swing.”<\/p>\n
The Bank of Korea plans to strengthen monitoring and assessment of the impact of single-stock leveraged ETFs on the stock market and financial system. With financial authorities already reviewing measures to raise investment barriers for these ETFs, the central bank is expected to present its views during consultations with relevant agencies. “We plan to consult closely with relevant authorities to address associated risks,” the Bank of Korea stated.<\/p>\n","protected":false},"excerpt":{"rendered":"The Bank of Korea has taken the unusual step of issuing a risk warning over so-called “Samsung-SK Hynix…\n","protected":false},"author":2,"featured_media":75102,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[845,35256,23726,335,40758,15259,7638,276,40757,241,240,275],"class_list":["post-75101","post","type-post","status-publish","format-standard","has-post-thumbnail","category-sk","tag-bank-of-korea","tag-financial-stability-report","tag-korea-capital-market-institute","tag-kospi","tag-lee-hyo-seob","tag-margin-loans","tag-park-sung-hoon","tag-samsung-electronics","tag-single-stock-leveraged-etfs","tag-sk","tag-sk-group","tag-sk-hynix"],"_links":{"self":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts\/75101","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/comments?post=75101"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/posts\/75101\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/media\/75102"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/media?parent=75101"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/categories?post=75101"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/korea\/wp-json\/wp\/v2\/tags?post=75101"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
