Updated
Citadel Securities has successfully executed a transaction involving tokenized US Treasuries on the Canton Network, utilizing the Depository Trust Company’s (DTC) Tokenization Service in a live production environment. This development, reported on July 15, 2026, marks a significant step in the ongoing initiatives by major financial players to digitize traditional assets.
In parallel, BNY Mellon is planning to pilot tokenized Treasuries on its proprietary blockchain by the end of 2026, with a stated goal of achieving 24/7 settlement in 2027. The DTC’s full Tokenization Service is scheduled for a voluntary launch in October 2026, initially covering US Treasuries and selected Exchange Traded Funds (ETFs).
Citadel’s Transaction Details
The transaction involving Citadel Securities saw the creation and movement of tokenized US Treasuries on the Canton Network, a blockchain platform designed for regulated financial institutions. Fireblocks provided the underlying technology that facilitated Citadel’s communications with DTC and its token transactions. This allowed Citadel Securities to hold the tokenized Treasuries in secure wallets and transfer entitlements to counterparties, including BNP Paribas and Société Générale. Furthermore, Citadel was able to use these tokenized Treasuries as collateral for trading on the CME.
It is important to note that these tokenized Treasuries are digital wrappers for government bonds and are not tied to any cryptocurrency or token ticker. This distinction is crucial for understanding the nature of these digital assets.
BNY Mellon’s Efforts and Market Context
BNY Mellon’s efforts in this space include a previously reported after-hours Treasury trade earlier in 2026, which, while not tokenized, was linked to stablecoin reserves. The broader context for these developments includes the significant Treasury reserves held by stablecoin issuers, where settling these reserves outside normal market hours addresses a mismatch between a 24/7 token market and a traditional 9-to-5 bond market.
Industry Participation and Divergent Approaches
More than 30 firms participated in the DTC tokenization event, underscoring broad industry interest. While Citadel chose to utilize the Canton Network and DTC’s service, BNY Mellon is developing its initiatives on its own proprietary blockchain. This divergence in approach may indicate a developing split between shared industry networks and bank-owned infrastructure for tokenized assets.
Key Dates and Future Outlook
Key dates for these developments include July 15, 2026, for Citadel’s transaction, October 2026 for the voluntary launch of DTC’s full Tokenization Service, the end of 2026 for BNY Mellon’s pilot, and 2027 for BNY Mellon’s 24/7 settlement goal.
Uncertainties remain regarding the extent to which firms will adopt DTCC’s service after its October 2026 launch, the successful on-schedule launch of BNY Mellon’s pilots, and the actual volume of tokenized collateral that may be utilized in live trading.
