Instant takeaway: Binance will adjust a batch of cross-margin / isolated account collateral ratios on September 18 at 06:00 (UTC, 14:00 in UTC+8). The update will be completed within about 30 minutes.

According to the Binance CMS announcement: the cross-margin borrow/transfer collateral ratios, unified account collateral ratio, and the tiered collateral ratios for Unified Account Pro (PM Pro) will be updated simultaneously.

Cross-margin / unified account scope (excerpt):
ARBTAOWLD: 50% → 60%
AUCTION、BLUR、GALAHYPER、S、SYRUP: 30% → 10%

For PM Pro: the tier brackets and the maximum collateral ratio for WLFI will be adjusted in sync (maximum increases from 50% to 60%).

The announcement states: changes to cross-margin borrow/transfer collateral ratios only affect the available borrowing and transferring limits under cross-margin. For unified accounts, the collateral ratio and leverage will affect uniMMR—so monitor it yourself to avoid potential liquidation or losses resulting from parameter changes. Product and services vary by region.

Independent verification: Coinlive and BlockBeats’ same-day quick news reports and the effective time, as well as the before-and-after collateral ratios of key assets and the uniMMR notice wording, are consistent.
