Binance cut collateral ratios for AUCTION, BLUR, GALA, HYPER, S and SYRUP from 30% to 10% on Sept. 18, while Coinbase International Exchange said 29 assets will leave its eligible-collateral list on Sept. 29. The changes reduce the value exchanges recognize for borrowing and margin calculations even when the underlying token price is unchanged. Binance also raised ARB, TAO and WLD ratios from 50% to 60%.
Why it matters
A trader holding $100,000 of an asset with a 30% collateral ratio receives $30,000 of recognized collateral value. At 10%, the same position contributes only $10,000, a $20,000 reduction and a 66.7% relative drop in usable collateral.
Binance said its Cross Margin change affects the amount customers can borrow or transfer out. In Portfolio Margin, collateral ratios feed the unified maintenance margin ratio, or uniMMR, which measures whether a combined portfolio has enough margin to support its positions. The effect depends on each account's other assets, liabilities and risk tier.
Market impact
Coinbase's list includes BNB, AVAX, ARB, ONDO, PEPE, SHIB and UNI. Customers relying on those assets may need to add collateral or reduce exposure, depending on their margin position. Binance also removed several cross-margin pairs and automatically settled remaining positions in the GENIUS/USDC isolated-margin pair.
The notices point to selective risk repricing rather than a coordinated move. Binance raised SYRUP's ratio from 10% to 30% on Sept. 4, then cut it back to 10% 14 days later. The measurable effects to watch are pledged collateral, borrowing utilization, margin calls, position reductions and liquidations.
