South Korean Kospi Surges 6% on AI Optimism Despite Weekly Loss

South Korean equities staged a dramatic recovery on Friday, with the benchmark Kospi index rallying nearly 6% amid renewed interest in the artificial intelligence sector. Despite this significant single-day jump, the market continues to face headwinds, recording its second consecutive weekly decline.

Tech Giants Drive the Kospi Rally

The primary catalyst for Friday's bullish sentiment was a massive rebound in heavyweight technology stocks. Samsung Electronics emerged as a standout performer, with its shares surging over 8%. This rally was fueled by reports that Anthropic PBC is in discussions with the chipmaker to establish a partnership for manufacturing custom AI chips.

Following Samsung's lead, SK Hynix saw its shares jump by 7%, providing much-needed momentum to the index. Even LG Energy Solution saw marginal gains. This surge comes after a difficult start to the week, where heavy losses in global tech companies had sparked fears that the AI-driven market rally might have reached its peak. On Friday, the Kospi surged 440 points, or 5.76%, reaching the 8,008 level.

Foreign Capital Outflows and Currency Pressure

Despite the intra-day recovery, the broader market sentiment remains cautious. For the full week, the Kospi ended down 3.84%. A significant factor contributing to this volatility is the movement of foreign institutional investors. According to Reuters, foreigners emerged as net sellers, offloading shares worth 1,501.9 billion won.

The South Korean won also faced significant pressure, weakening against the US dollar. On the onshore settlement platform, the won was quoted at 1,544.4 per USD, a 0.28% decline from its previous close. This depreciation highlights a larger trend, as the won has fallen 6.8% against the USD so far this year.

While the equity market experienced high volatility, the money and debt markets showed more stable movements. In the bond market, September futures on three-year treasury bonds gained 0.08 points to settle at 103.11.

Yields on Korean government bonds also saw a slight decline. The yield on the most liquid three-year Korean treasury bond slipped by 1.5 basis points to 3.732%, while the benchmark 10-year yield fell by 0.7 basis points to 4.173%. These movements suggest a slight shift in investor positioning within the debt markets amidst the broader economic fluctuations.
