The Korea Exchange, which was scheduled to introduce a weekly right to a single stock on June 29th, decided to postpone it before it approached the line. By reference to sources, Bloomberg stated that the discussions were still ongoing and the Korea Exchange spokesperson stated that a final decision had not yet been taken.

It was supposed to cover four Korean blue-chips.

As previously planned, the weekly options would cover SK Hercules, Samsung Electronics, Modern Motors and LG new energy. The weekly product duration is shorter than the current monthly option and is usually more suitable for short-line trading and higher-frequency risk hedges.

The Korean market is now on the market, with only a monthly option. The routing of products means that the exchange will further expand the supply of short-term derivatives to meet investors ' demand for more flexible trading instruments.

The regulatory layer has recently turned to caution.

This extension took place after the Korean regulatory authorities expressed their opinion on another category of highly volatile products. The Supervisory Level has recently expressed regret over the single leverage ETF launched in May this year and warned that the negative impact is increasing.

Against this background, the temporary postponement of weekly options is seen by the market as a signal for regulators to reassess the risks of short-cycle leverage instruments. Particularly after the rapid rise of the stock market, there has been a marked rise in fear of speculation at the regulatory level.

Stock market shock increases the sense of caution.

The South Korean stock market was once one of the world's strongest-performing major markets this year, but the increase was also marked by increased volatility. The next day, after the initial high of Monday, the Korean Composite Equity Index fell by about 10 per cent, and the shock triggered regulatory concerns.

In international markets, short-term options have expanded rapidly in recent years. In the United States, 0DTE options already account for more than half of the 500 index options traded, and Hong Kong, China, has continued to increase the activity of related transactions since the introduction of a weekly stock options in 2024.

However, the Republic of Korea has been sensitive to the risks of derivatives speculation. The Kospi 200 index option, which became one of the most active contracts in the world in the 2000s, was subsequently tightened in the early 2010s by increased speculation and volatility. These restrictions have been gradually eased in recent years as the Republic of Korea wishes to attract more overseas funds.

This delay shows that, against the backdrop of increased valuations and increased heat from bulk trading, the Korean regulatory hierarchy continues to place market volatility control ahead.
