币界网报道：Binance announced adjustments to the Bitcoin (BTC) collateral ratio for margin trading, effective July 4, 2025. The exchange will lower the initial and maintenance margin ratios for BTC cross-margin pairs from 15% to 10%, aiming to enhance liquidity and trading flexibility. Binance emphasized that the change aligns with its commitment to optimizing user experience while maintaining robust risk management. The platform advised traders to monitor positions closely, as reduced collateral requirements may increase leverage exposure. Additionally, Binance plans to introduce similar adjustments for other major cryptocurrencies in the coming months, pending market conditions. The move follows industry trends of exchanges refining margin products to attract institutional and retail participants amid growing crypto derivatives activity. Analysts suggest the update could boost trading volumes but caution users to assess risk tolerance given potential volatility. Binance last revised its margin trading terms in 2023, when it temporarily suspended some leveraged tokens due to extreme market swings. The exchange continues to dominate global crypto trading, with derivatives accounting for over 60% of its reported volume in Q2 2025.
