Key Points
1
Foreign investors recorded net sales of 233.5 billion won, contributing to a broad market retreat in Seoul.
2
The Bank of Korea delivered back-to-back rate hikes, lifting the policy rate to 3.00% — the first such sequence since January 2023.
3
Nvidia surged about 8.74% on its earnings/outlook, underscoring a Wall Street AI rally that did not translate into gains for Korean chipmakers.
4
Samsung BioLogics fell around 5.9% after announcing plans to raise capital via a rights offering.
South Korea's stock market slipped on August 28 as BigGo Finance reported the KOSPI fell 1.2% amid persistent foreign and institutional selling pressure. The decline came despite a rally in U.S. tech stocks, as investors rotated out of Korean equities ahead of Federal Reserve Chair Kevin Warsh's Jackson Hole speech and the Bank of Korea's back-to-back rate hikes.
Foreign investors recorded net sales of 233.5 billion won, according to market data, while large-cap names like Samsung Electronics and SK hynix fell alongside the broader index. Seoul Daily noted the KOSPI opened at 6,846.84, down 65.53 points, as traders stayed cautious ahead of key policy signals from Washington.
Central Bank Rate Hikes Add Pressure to Market Sentiment
The Bank of Korea delivered back-to-back rate hikes this month, raising the policy rate to 3.00% — the first consecutive increases since January 2023. This tightening cycle weighed on investor sentiment as borrowing costs rise and economic growth concerns persist. Higher rates typically pressure equity valuations, especially for growth-heavy sectors like technology.
Tech Giants Decline Despite Wall Street AI Boom
Nvidia surged about 8.74% on strong earnings and forward guidance, lifting U.S. indices and fueling a broad artificial intelligence rally on Wall Street. However, this momentum did not carry over to Korean chipmakers. Samsung Electronics and SK hynix both fell as investors sold down Seoul's most expensive names, preferring to de-risk ahead of Jackson Hole communications.
The divergence highlights how global macro concerns can override sector strength. Even with Nvidia's gains signaling AI momentum, Korean tech stocks faced headwinds from foreign outflows and uncertainty about U.S. monetary policy direction.
Foreign Outflows Intensify Ahead of Fed Signals
Foreign and institutional investors dumped shares throughout the session, with net sales totaling 233.5 billion won. Traders adopted a wait-and-see stance ahead of BigGo Finance's reported Jackson Hole speech by Federal Reserve Chair Kevin Warsh, expecting clarity on U.S. rate cuts or holds. This caution suppressed trading volumes despite overnight strength on Wall Street.
The Asia-Pacific region felt similar pressure, though the MSCI Asia Pacific gauge added modest gains. South Korea's export-heavy economy remains sensitive to currency swings and Fed policy shifts, making foreign investor sentiment a key driver of daily moves.
Samsung BioLogics Falls on Capital Raise Plan
Samsung BioLogics dropped around 5.9% after announcing plans to raise capital via a rights offering. The biotech company's decision to dilute existing shareholders signaled either growth opportunities or near-term funding needs, both of which pressured the stock. The move added to selling in large-cap names already facing foreign outflows.
