Impact Assessment

This modification reduces the contract size significantly from 1 Kg to 100 grams, making Silver futures more accessible to a broader range of participants with lower capital requirements per lot. Trading members need to update their back-office and trading systems to accommodate the symbol change from SILVERMIC to SILVER100 and the new pricing basis. Failure to upload the updated contract file before June 1, 2026 may disrupt trading operations. Members with open positions in SILVERMIC contracts approaching the June 2026 expiry should assess the transition impact on their portfolio valuation and margin requirements.
