Woofun AI reports that China Construction Bank, CMB, and Bank of China have simultaneously adjusted margin ratios for individual precious metals deferred contracts on the Shanghai Gold Exchange. China Construction Bank will uniformly raise margins for all gold and silver deferred contracts to 120%, while CMB increases margins from 100% to 140%, with both changes effective from the June 22 closing settlement.

Additionally, Bank of China will adjust individual gold deferred contract margins from 99.9% to 120% and silver from 99.96% to 119.91%, effective from the June 24, 2026 closing settlement.

Suixin Bank special researcher Wu Zewei noted that margin ratios exceeding 100% substantially reset leverage for individual precious metal deferred transactions to zero.

This shift significantly reduces space for short-term speculative trading, lowers fund utilization efficiency, and increases high-frequency trading costs, prompting speculative funds to exit. While short-term trading volume may decline, these measures aim to squeeze out irrational speculative bubbles, fostering more stable and orderly market operations.
