Regulatory Changes
Implementation of ST-ASM Stage I surveillance measure with specific margin requirements for identified securities based on market surveillance criteria.
Compliance Requirements
- Market participants must apply 50% margin or existing margin (whichever higher) on all open positions as of September 1, 2025
- New positions created from September 2, 2025 onwards subject to enhanced margin requirements
- Maximum margin rate capped at 100%
Important Dates
- September 1, 2025: ST-ASM Stage I becomes applicable for listed securities

Impact Assessment
Limited market impact as only two securities are affected by increased margin requirements. The exclusion of three securities from ASM framework provides relief to those stocks. Enhanced margins may reduce speculative trading in the affected securities while maintaining market integrity through surveillance measures.
Impact Justification
Affects specific securities with increased margin requirements but limited to two stocks
