South Korea leveraged ETF assets surge 800% as central bank warns on concentration

Bank of Korea said leveraged ETFs tied to Samsung Electronics and SK Hynix could amplify volatility and one-way trading flows after assets in South Korea leveraged ETFs climbed to about $45 billion.

Fact Check
The core claim is confirmed by multiple independent authoritative sources. Chosunbiz and Bloomberg (via Yonhap) confirm the Bank of Korea's July 5, 2026 warning that single-stock leveraged ETFs tied to Samsung Electronics and SK Hynix could amplify volatility and deepen concentration, with daily rebalancing potentially triggering one-sided (one-way) transaction concentration — matching the claim precisely. The ~$45 billion assets figure and the 800%+ surge since January 2026 are corroborated by Cryptobriefing. The Chosunbiz report ties the warning explicitly to the BOK Financial Stability Report and provides concrete concentration data. Only minor caveats: the exact 800% and $45B figures originate largely from secondary/crypto-adjacent outlets rather than the BOK's original report text, but they are consistent across sources.
Summary

Assets in South Korea leveraged ETFs have risen about 800% since the start of 2026 to a record roughly $45 billion, according to The Kobeissi Letter, as retail investors increased high-risk equity bets and shifted from crypto into leveraged exchange-traded products. The Bank of Korea warned in a written reply to People Power Party lawmaker Park Sung-hoon that leveraged ETFs tied to Samsung Electronics and SK Hynix could deepen market concentration, amplify volatility and reinforce one-way trading flows, and said it plans to strengthen monitoring of their effects on markets and financial stability. Leveraged and inverse ETFs tracking SK Hynix hold about $19 billion in assets versus roughly $4.5 billion in average daily trading, while Samsung-linked leveraged ETF assets are about $12.4 billion, or 176% above the stock's roughly $4.5 billion daily turnover.
