KOSPI Reclaims 6,800: US CPI Slowdown and Semiconductor Rally Analysis
On August 13, the KOSPI index surged past the 6,800 mark, led by semiconductor stocks, following easing rate hike concerns due to the US July CPI slowdown.
KOSPI Reclaims 6,800 Driven by a Relief Rally
On August 13, 2026, the South Korean stock market entered a distinct upward trend driven by a relief rally. According to major news reports, the KOSPI index opened strong at 6,773.92, up 2.96% from the previous trading day, and quickly surpassed the 6,800 mark in early trading. This indicates a significant improvement in investor sentiment, continuing a positive trajectory for three consecutive trading days.
Easing Rate Hike Concerns Amid Cooling Inflation
The primary catalyst for this surge is the stabilization of US inflation indicators. The US Consumer Price Index (CPI) for July, released on the 12th (local time), rose by 3.4% year-over-year, perfectly aligning with market expectations. The core CPI growth rate, which excludes volatile items, also recorded 2.5%, down from the previous month (2.6%), confirming that inflationary pressures are easing.
These results acted as a decisive factor in lowering the probability of an interest rate hike by the US Federal Reserve in September. As global tightening concerns eased, suppressed appetite for risk assets quickly flowed back into the domestic stock market.
The Return of Semiconductor Leaders and Future Outlook
By sector, the strong performance of large-cap semiconductor stocks stands out. The positive momentum from AI infrastructure-related companies in the New York stock market overnight carried over to the domestic market. Major semiconductor stocks, including Samsung Electronics and SK Hynix, surged by 4% to 6%, strongly driving the KOSPI's steep ascent.
While the market is expected to maintain a favorable trend for the time being, caution remains. Some experts point out that the possibility of a rebound in August inflation due to international oil price fluctuations cannot be ruled out. Therefore, investors need to carefully monitor changes in macroeconomic indicators and corporate earnings guidance to manage risks effectively.
