Yesterday's Recap

South Korean equities declined sharply on September 13 as concerns over AI valuations weighed on chipmakers. The KOSPI closed at 6,909.91, down 1.76%, while the KOSDAQ fell 1.95% to 820.64. Samsung Electronics dropped 3.53% to 259,500 and SK Hynix declined 2.21% to 1,812,000.

The won strengthened, with USD/KRW finishing at 1,345.90. Korea’s long-term government bond yield rose 2.60% to 4.18% while the short-term rate held steady at 2.54%. No major economic data releases occurred.

Korean banks prepared to supply 103 trillion won in liquidity ahead of the Chuseok holiday. The stronger won also reduced the local-currency value of US equity holdings for retail investors, amplifying pressure on semiconductor exporters already facing valuation scrutiny.

The Day Ahead

No scheduled economic data releases or Bank of Korea policy events are set for September 14. Markets will continue to monitor the impact of the stronger won on semiconductor earnings and retail investor flows into US equities. Attention remains on supply-chain adjustments as South Korea expands ASEAN transit routes amid US-China reconfiguration.

Traders will also track any follow-through from the BOK’s recent warnings on AI-chip leverage. Holiday liquidity measures from domestic banks may support short-term funding conditions through the week, while Brent crude at 106.24 and gold at 4,338.90 offer mixed signals for importers.

Other Economic Notes

Korea’s tax revenue rose 41 trillion won through July, reflecting stronger corporate collections. The government secured a final victory in a 264.1 billion won investor-state dispute against a Chinese claimant. The South Korean envoy to Bangladesh urged faster conversion of the CEPA into joint-venture manufacturing projects.

These developments underscore improving fiscal inflows and continued efforts to diversify export markets beyond traditional partners, even as the won’s appreciation creates headwinds for earnings translation at major chip firms.

Global Macro News

Global investors reacted to persistent AI valuation concerns that spilled over into Korean semiconductor stocks. The stronger won reduced the local-currency value of US equity holdings held by Korean retail investors. US-China supply-chain shifts continued to favor ASEAN routing, a trend the Bank of Korea explicitly noted in recent commentary.

Brent crude rose 1.56% to 106.24 while gold eased 1.59%, signaling mixed commodity signals for Korean importers. Bitcoin gained 2.75%, offering limited offset to equity weakness. Broader risk-off sentiment lifted Korea’s long-term yields even as the short-term policy rate remained anchored.

BoK Watch

The Bank of Korea warned that excessive leverage in AI-chip related assets poses risks to financial stability. Officials also collaborated with the Korean Statistical Society to explore AI applications for economic data compilation while stressing the need to maintain reliability in the AI era. No rate decision or minutes were released on September 13, leaving the committee’s forward guidance unchanged.

The stronger won and higher long-term yields together suggest markets are pricing in continued caution on both growth and inflation. The BOK’s emphasis on supply-chain resilience through ASEAN transit indicates ongoing monitoring of external shocks. Market participants interpret these signals as consistent with a steady policy stance absent fresh inflation surprises.
