Odaily Planet Daily reports that Citigroup and the American Depository Trust & Clearing Corporation (DTCC) stated at the SmartCon conference in New York that tokenized collateral across borders and assets has been implemented in real-world transactions and is technically feasible, but the lack of unified regulatory standards remains a major obstacle. Citigroup explained that its "Citi Token Services" is already online in the US, UK, Hong Kong, and Singapore, having processed billions of dollars in client funds and settlements. DTCC, through its "Great Collateral Experiment," has verified that tokenized US Treasury bonds, stocks, and money market funds can be used as collateral across time zones. Both companies emphasized that without a unified legal and standards framework, the global financial system may face fragmentation and compliance risks, and institutions such as SWIFT have participated in developing relevant shared protocols.
