KOSPI Selloff Driven by Financing Costs, Not Weak Profits, Analysts Say

South Korean stocks have sold off sharply despite a robust corporate earnings season, as investor focus shifts from strong profits to macroeconomic headwinds like financing costs and geopolitical uncertainty, according to a research note from KB Securities.

Valuation Pressure Eclipses Earnings

KB Securities analysts argue that resilient earnings are not the primary driver of the benchmark KOSPI index's recent decline. Instead, the market is increasingly viewing capital-intensive investments, particularly in artificial intelligence, through the lens of funding costs rather than long-term growth prospects. This has put pressure on index heavyweights, with both Samsung Electronics and SK Hynix posting steep declines from recent peaks.

The note highlights that investor concerns over the return on AI-related capital spending are not new. A similar selloff occurred last November, which later reversed on expectations of U.S. Federal Reserve rate cuts. KB Securities contends that the recovery was driven by the prospect of lower borrowing costs, not a fundamental increase in confidence about AI profitability.

Macro Factors in Focus

Renewed geopolitical tensions in the Middle East have pushed U.S. Treasury yields higher, reviving fears of tighter monetary policy and weighing on equity valuations. According to the report, a sustained rebound in the KOSPI will likely require a combination of two factors:

Ad

• A macroeconomic catalyst that stabilizes interest rates.
• A company-specific event that restores confidence among capital providers.

However, the brokerage expects geopolitical uncertainty to ease over time, citing potential political pressure on the Trump administration ahead of the U.S. midterm elections, where higher oil prices and borrowing costs could negatively impact voter sentiment.

Potential Policy Catalysts

KB Securities also pointed to a policy proposal from OpenAI as a potential positive development for market sentiment. The proposal involves granting the U.S. government a 5% equity stake to establish an AI-focused sovereign wealth fund.

Analysts believe such a move, if adopted, could reduce the perceived default risk for AI investments, thereby lowering funding costs and narrowing corporate credit spreads. The report cautioned that greater government backing could also encourage excessive risk-taking and inflate asset bubbles over the longer term.
