Tokenised US Treasuries Could Be Bitfinex Margin Collateral

Bitfinex Securities has announced that its tokenized short-term US Treasury product, USTBL, is now eligible as collateral for margin trading on its peer-to-peer platform. Issued by NexBridge Digital Financial Solutions, USTBL allows investors to maintain exposure to Treasury yields while simultaneously leveraging the asset to support margin positions. Under the new terms, users can pledge their USTBL holdings to receive a corresponding USDT collateral balance in their margin wallet, subject to a 10% haircut. This integration enables up to 90% of the tokenized Treasury value to be utilized for trading, effectively increasing capital efficiency for market participants. By adding USTBL to its existing collateral list—which includes Bitcoin, Ethereum, and XAUt—Bitfinex aims to provide greater flexibility for users seeking both yield generation and active trading opportunities. This development highlights the growing utility of tokenized government debt as a foundational asset within digital asset ecosystems. The move reflects a broader trend of integrating traditional financial instruments into crypto-native margin markets to optimize portfolio management.
