The chief of South Korea's National Pension Service warned that the won's weakness against the dollar during recent market turmoil may require action to stabilize the currency. The nation's largest pension fund manages about $1 trillion in assets and its CEO's comments carry significant weight in financial markets.

The remarks come amid broader concerns about emerging market currencies as global investors seek safe havens in the US dollar. The South Korean won has faced pressure from various factors including rising US interest rates and geopolitical tensions.

Currency stability is crucial for South Korea's export-driven economy, where fluctuations in the won can impact corporate earnings and investment flows. The pension fund's warning suggests authorities may be considering intervention to prevent further depreciation of the won.
