South Korea's exchange announced on Thursday that it has postponed the launch of weekly options for four major stocks, originally scheduled for next Monday, June 29th.

The four major stocks are Samsung Electronics Co Ltd, SK Hynix Inc, Hyundai Motor Co, and LG Energy Solution Ltd.

In a statement, the exchange said the decision to delay the weekly options launch was made in light of "recent market conditions."

The exchange further stated that it will proceed with the introduction of the weekly options based on "market conditions and related preparatory work."

Earlier this week, the head of South Korea's Financial Supervisory Service, Lee Chan-jin, had warned that newly launched single-stock leveraged exchange-traded funds (ETFs) could negatively impact stock market volatility.
