Société Générale has accepted $10 million in DTCC-tokenized U.S. Treasuries as collateral on Canton Network, the bank said on November 2, 2026. The transaction brought the assets into its existing collateral and back-office systems—but bank acceptance does not change how DTC values tokenized entitlements in its own risk calculations.
Key takeaways
Société Générale’s Prime Services & Clearing division accepted the tokenized Treasuries.
DTC-held securities back the tokens at a 1:1 ratio.
Token transfers operate around the clock, but conversions have business-day limits.
Société Générale accepts DTCC-tokenized Treasuries as collateral
The bank’s Prime Services & Clearing division accepted the assets on Canton Network under Société Générale’s governance, risk and control framework. In carrying out the transaction, the company moved forward with a plan announced in May to accept tokenized assets as collateral on Canton.
Société Générale said the securities were tokenized during the soft launch of the Depository Trust & Clearing Corporation’s Tokenization Service. Their acceptance integrated tokenized assets with the bank’s existing operational systems.
How DTCC’s tokenization service works
DTCC’s Tokenization Service launched on October 28, 2026 , enabling eligible users to turn securities held at The Depository Trust Company, its depository subsidiary, into tokenized representations.
DTCC ’s service fact sheet specifies 1:1 backing by securities held at DTC, which maintains the official ownership records. Transfers can take place only between DTC-registered wallets , rather than unrestricted crypto wallets.
Peer-to-peer transfers on a supported blockchain can operate 24/7 . Switching between tokens and traditional book-entry securities is limited to 2 a.m. through 6 p.m. ET on business days , with processing targeted at 15 minutes or less.
Bank acceptance differs from DTC’s risk treatment
Société Générale’s use of DTCC-tokenized Treasuries as collateral does not alter DTC’s internal treatment of those tokens. The bank’s acceptance and the depository’s risk calculations remain separate.
Per the framework laid out in the SEC’s December 2025 no-action letter , DTC assigns tokenized entitlements neither collateral value nor settlement value in its own risk calculations. Société Générale accepted the assets under its bank-level governance and controls, not through a change to that framework.
Recurring collateral movements and onchain financing
Société Générale intends to support recurring collateral movements and assess additional eligible tokenized securities. The bank also plans to explore onchain repo financing, subject to approvals and regulatory requirements.
Its stated conditions for further financing activity include internal approvals, regulatory requirements and additional development of its operational and control framework.
