South Korea\'s economic and financial authorities plan to set individual investment limits on single-stock leveraged exchange-traded funds tied to Samsung Electronics and SK Hynix. They also aim to establish legal grounds to allow direct stabilisation measures, including adjusting leverage ratios in urgent market conditions. Measures under review include imposing trading costs to curb excessive orders and adding simulated trading to investor education. Authorities said they will move immediately on the steps and will keep 24-hour market monitoring.

The won-dollar rate has swung sharply this year, hitting an annual high of 1,562 won before easing to the 1,530 range. The won remains at crisis-levels even as the KOSPI breaks above 9,000 and the current account posts a record. The Financial Times cited structural factors, including chipmakers reinvesting dollar earnings overseas and rising demand for dollars from outbound investments. Authorities and experts are watching further pressures in July and August.
