Correction — 22 October 2026: The original 7.06% KOSPI decline is corrected to a 3.26% gain. The article described a June 24 Korean observation as a June 25 move. Its broad deleveraging interpretation and claims of a Korean crash are withdrawn. This is a retrospective review using daily history retrieved on 2026-10-22, not a live report or a reconstruction of every quote available at original publication.
Reconstructing the Korean return
The Korean index moved from 8,203.84 on 2026-06-23 to 8,471.02 on 2026-06-24. Dividing the later value by the earlier value, subtracting one and multiplying by 100 gives +3.26%. The previous article reported -7.06%. The difference is material because it reverses the direction of the return.

Mixed equity performance weakens the original premise
Gold futures fell 3.39%, WTI fell 3.92%, the S&P 500 fell 0.10%, and the Nasdaq fell 0.43%. KOSPI rose 3.26% in its earlier session. The table therefore does not show all the cited equity markets selling off together. Even simultaneous declines would not alone prove margin calls or forced liquidation; such a claim needs leverage, transaction or flow evidence.
Method and limits
Percentage changes use (value ÷ previous available daily value − 1) × 100, before rounding. Yield changes use the difference in percentage-point quotes multiplied by 100 to obtain basis points. Currency values are local-currency units per US dollar. Index levels are in points; futures quotes are in US dollars per barrel for WTI and per troy ounce for gold.
Each linked Yahoo Finance history is the data source for that row. These provider observations have not been independently checked against exchange settlement records. The futures series can change its referenced contract over time and should not be treated as the return on a continuously held investment. A date shared by two markets does not make their closing times simultaneous.
