KOSPI Falls Below 7,000 As Oil Prices Surge And Interest Rates Rise

South Korea’s KOSPI fell 1.76% to 6,909.91 as oil prices climbed above $100 a barrel and bond yields rose. Heavy foreign and institutional selling weighed on stocks ahead of the US August CPI release.
South Korea’s benchmark index, the Korea Composite Stock Price Index (KOSPI), fell sharply on Friday, 11 September, as surging international oil prices and rising interest rates weighed on investor sentiment.
The KOSPI closed at 6,909.91, down 124.01 points, or 1.76%, slipping below the 7,000 level for the first time in three trading sessions. The index had opened at 6,802.50, a decline of 3.29%, before recovering part of its early losses.
Foreign and institutional investors remained net sellers, while retail investors and other corporations provided some support. Foreign investors also sold 680 billion won worth of KOSPI 200 futures. The won weakened to 1,345.9 per dollar, down 6.7 won from the previous session.

Oil Prices And Bond Yields Rise
Brent crude futures climbed to $105.74 a barrel, while West Texas Intermediate (WTI) reached $100.92, with both benchmarks moving above the $100 threshold.
The rise in energy prices intensified inflation concerns and pushed borrowing costs higher. The 10-year US Treasury yield moved above 4.9%, while South Korea’s three-year government bond yield exceeded 4.0% during the session, reaching its highest level in roughly three years.

US Consumer Price Index (CPI) in Focus
Investor activity remained subdued ahead of the release of the US Consumer Price Index for August. Concerns over inflation, oil prices and interest rates kept investors cautious, with trading also affected by the approaching weekend.
Trading value reached 19.39 trillion won on KOSPI, and 6.36 trillion won on KOSDAQ, while Nextrade recorded 8.8565 trillion won across its pre-market and regular sessions.
