Korean retail investors lost $250 million from scams during stock swing

South Korean retail investors lost an estimated $250 million to fraud in the first half of 2026, as scammers took advantage of market volatility to steal from investors. Police investigated 3,506 cases related to stock tip chatrooms, involving $246.57 million from January to June. KOSPI, South Korea's stock benchmark, was the world's best-performing stock in the first half but lost 44% from its June 19 peak.

The number of cases increased by just 4.1% compared to the same period last year, but the amount of money involved rose 19.8%. Lawyers say inexperienced retail investors were particularly vulnerable to scams exploiting fear of missing out on the sharp rally. Scammers used tactics like posting comments on videos of financial influencers, offering paid stock recommendations, and sending victims to private chatrooms to convince them to transfer money.

Jay, a 47-year-old logistics worker, lost 60 million won after falling for a similar scam via a TikTok video, believing the group's manager to be an employee of a securities firm. South Korea's financial regulator has no data on illegal stock-tipping chatroom cases, with the responsibility for investigating such cases falling to law enforcement agencies.
