TAIFEX stated that the adjustment will take effect after the regular trading session on August 12 (the first business day after the securities market monitoring takes effect) and will revert to the pre-adjustment margin after the securities market monitoring period ends, effective after trading on August 17. If there is a market holiday, trading suspension, or full-day trading halt during the monitoring period, the reversion date will be postponed accordingly.

TAIFEX reminds investors that futures trading involves margin requirements, and investors must continuously monitor the risk of their open positions, understand the margin's risk coverage, and pay attention to the risk management measures agreed upon with their futures brokers.

TAIFEX emphasizes that investors should enhance their risk awareness, closely monitor their account positions and equity changes, and timely deposit sufficient margin to avoid losses exceeding their risk tolerance during periods of sharp market price fluctuations, thereby safeguarding their trading security.
