Binance Futures Adds United Stables (U) as Margin Asset Starting Feb 5

Binance integrates United Stables (U) stablecoin as margin collateral in Multi-Assets Mode, offering traders a new settlement option with 1% haircut rate.
Binance Futures will integrate United Stables (U) as a margin asset within its Multi-Assets Mode beginning February 5, 2026 at 07:00 UTC, giving traders another stablecoin option for collateralizing futures positions. The move marks continued expansion of the two-month-old stablecoin's utility across major trading venues.
United Stables, which launched in December 2025, currently holds a market cap of approximately $760 million and trades at $0.9995—maintaining its dollar peg with minimal deviation. The token operates natively on both BNB Chain and Ethereum, positioning it as a cross-chain settlement layer designed to aggregate liquidity from multiple fiat-backed stablecoins.
Under the new integration, U will carry a 1% haircut rate during auto-exchange events, with margin balances calculated against the real-time U price index. This puts it on relatively favorable terms compared to volatile assets, though traders should note that haircut rates can shift based on market conditions.
The Multi-Assets Mode feature allows traders to use various assets as collateral rather than being locked into a single margin currency. Someone holding U can now use it directly as margin when trading any supported perpetual contract—BTC, ETH, or the recently listed AIAUSDT perpetual—without first converting to USDT or BUSD.
For the stablecoin market, this integration represents another step toward fragmenting USDT's dominance in derivatives collateral. United Stables' pitch centers on being a "neutral USD settlement asset" that reduces friction between different stablecoin ecosystems. Whether traders actually shift margin preferences remains to be seen—habit and liquidity depth often trump marginal efficiency gains.
The timing aligns with broader stablecoin developments. Ondo Global Markets filed a registration statement with the SEC on February 4, signaling continued institutional interest in regulated stablecoin infrastructure.
Traders looking to utilize U as margin should verify their Multi-Assets Mode settings before the February 5 activation. Binance notes that contract specifications including leverage limits and margin requirements may adjust based on market risk conditions.
