South Korea to closely watch risks around stock market volatility

SEOUL, July 8 (Reuters) – South Korea’s finance minister agreed on Wednesday with other economic policymakers to closely monitor risk factors that could heighten stock market ​volatility, the ministry said.

Stock market volatility has risen ‌amid foreign and institutional profit-taking, portfolio rebalancing and shifting expectations for the global AI sector, the ministry said in a statement after Minister Koo Yun-cheol met with the central bank governor and the ‌heads ​of financial regulators.

The KOSPI fell as ⁠much as 4% in early ⁠trade to its lowest level since May 20, before erasing losses to turn higher on a rebound in chipmaker stocks. The index was up 0.5% as of ​0052 GMT but was still down 15.6% from the record peak hit on June 22.

Earlier this week, the ⁠index triggered a circuit breaker ⁠for the sixth time this year, and ​the 12th in history, as sharp swings in heavyweight chip stocks ​such as Samsung Electronics and SK Hynix fuelled ‌heightened market volatility.

“Increasing concentration in the semiconductor sector has become a factor raising financial market volatility, with the impact of fluctuations in the chip sector on the whole stock ⁠market growing,” the ministry said, following a series of warnings from regulators.

The Financial Supervisory Service said on Tuesday that it would ⁠monitor the market ‌impact of recently-introduced single-stock leveraged exchange ⁠traded funds (ETFs) linked to chipmaker stocks and review ​marketing ‌practices by asset management firms if needed.

The ​Bank of ⁠Korea said on Sunday it would coordinate with other agencies to address related risks, warning that single-stock leveraged ETFs can amplify one-sided trading, increase concentration in specific stocks and exacerbate market volatility.
