Société Générale Accepts $10 Million in Tokenized Treasuries as Collateral on Canton
Key Facts
Société Générale’s securities services and clearing unit accepted $10 million in tokenized U.S. Treasuries as eligible collateral on the Canton network, in a transaction the bank announced in New York on November 2, 2026. The deal used assets tokenized during the launch of the Depository Trust & Clearing Corporation’s (DTCC) tokenization service. The bank said the transaction completed the on-chain transfer of representations of the securities and demonstrated that they could be included in institutional collateral arrangements. The move marks the use of tokenized securities as collateral after issuance, while the bank plans to explore on-chain financing at later stages. The Asian Banker published the statement on November 3, while the banking group published it as an announcement dated the previous day.
Société Générale said the Treasury representations were transferred on-chain and reflected in its existing back-office and collateral management systems, within its governance, risk and control framework. This means the transaction linked the tokenized asset to the bank’s internal operating workflow, rather than merely recording it on a digital network. The assets were handled through the existing collateral infrastructure, according to the statement, and shown in the bank’s back-office systems. Selim Noumchi, the bank’s global head of securities services, described the deal as one that “takes tokenization beyond issuance and starts connecting tokenized securities to funding markets.” He added that the bank aims to develop solutions for its clients, pointing to broader use of these assets in financing activities. The statement did not describe the transaction as a completed repurchase agreement; it listed repo models among the areas the bank intends to explore.
The transaction follows Société Générale’s issuance of its first tokenized U.S. bond on the Canton network in November 2025, according to the statement, placing the collateral acceptance within a broader path that began with the issuance of digital securities. In May 2026, the bank announced that it had joined the network as a super validator, another step in its institutional participation in the network’s infrastructure. The current transaction tests the use of tokenized Treasuries as eligible collateral, linking the asset’s issuance with the movement of collateral within existing banking systems. This sequence reflects a gradual shift from offering tokenized instruments to testing their market functions, with subsequent financing steps remaining part of the bank’s plans. Noumchi said the deal starts connecting tokenized securities to funding markets, without announcing the launch of a specific financing model at this stage.
The transaction falls within DTCC’s asset tokenization service, whose initial phase focuses on U.S. Treasuries held on-chain by the organization’s members and held in custody at the Depository Trust Company (DTC). DTCC said the service began on October 28, 2026, under a no-action letter issued by U.S. Securities and Exchange Commission staff in December 2025, and that the authorization runs for three years. The SEC had issued its letter to DTC on December 11, 2025, concerning an initial voluntary program to tokenize assets on supported blockchains. The service currently integrates with the Canton network and DTCC’s private Besu network, while the organization expects to add other blockchain networks in 2027. This places Société Générale’s collateral acceptance within a recently launched service, with network expansion announced for the coming years.
The service launch was preceded by a limited production test that included repo transactions in U.S. Treasuries and purchases and sales of Treasuries and equities using tokenized assets held in custody at DTC, according to DTCC. In May 2026, the organization said the service had been designed in collaboration with more than 50 financial firms, and at the time set out plans for limited initial production trading in July and a service launch in October. These milestones show that tokenization in institutional infrastructure extended to live trading trials before the service launched, while Société Générale’s deal came after it began operating. DTCC said assets worth more than $114 trillion are held in custody at DTC, the infrastructure underpinning the tokenization service. This background links the current transaction to a large-scale custody infrastructure, without changing the announced deal size of $10 million.
Société Générale said it intends to develop support for recurring collateral movements, assess additional tokenized securities that could be accepted, and explore on-chain financing. The models cited by the bank include repurchase agreements as agent or principal, but remain under study and part of a future plan. The statement tied progress on these steps to obtaining internal approvals, meeting regulatory requirements and completing operational and control work. The bank did not set a timeline for launching those movements or financing, and the statement did not announce acceptance of other assets in the transaction. The announced step remains the acceptance of $10 million in tokenized Treasuries as eligible collateral on Canton, while any broader use depends on completing the requirements cited by the bank.
