Citadel Securities and BNY Mellon Advance Tokenized US Treasury Initiatives

On July 15, 2026, Citadel Securities utilized the Depository Trust Company’s (DTC) Tokenization Service to create and transfer tokenized US Treasuries on the Canton Network in a live production environment. This marked a significant step in the integration of blockchain technology within traditional finance.

Citadel's transaction was facilitated through DTC, which serves as a central post-trade utility for US securities settlement. The Tokenization Service enables firms to create digital token representations of securities that are already part of the conventional system. These tokens were hosted on the Canton Network, a blockchain specifically designed for regulated financial institutions. Fireblocks, a digital asset infrastructure provider, played a crucial role in enabling Citadel’s interactions with DTC and managing its token transactions.

With this setup, Citadel was able to securely hold the tokenized Treasuries in digital wallets and transfer entitlements to counterparties such as BNP Paribas and Société Générale. Additionally, these tokenized Treasuries were utilized as collateral for trading on the Chicago Mercantile Exchange (CME). Notably, over 30 firms participated in the DTC tokenization event, exploring various use cases.

In a separate initiative, BNY Mellon is set to pilot tokenized Treasuries on its proprietary blockchain by the end of 2026, aiming for 24/7 settlement capabilities by 2027. Earlier in 2026, BNY Mellon executed an after-hours Treasury trade linked to stablecoin reserves, although it was not tokenized. Currently, there is no confirmed collaboration between Citadel and BNY Mellon regarding joint tokenized asset transactions.

The broader timeline includes the DTCC's planned voluntary launch of its full Tokenization Service in October 2026, which will initially focus on US Treasuries and selected ETFs. This development is significant as it addresses the need for stablecoin issuers, who hold substantial Treasury reserves, to settle those reserves outside of traditional market hours, highlighting the disparity between a 24/7 token market and a conventional 9-to-5 bond market.

As Citadel opts for the Canton Network and DTC’s service, BNY Mellon’s approach indicates a potential divergence between shared industry networks and bank-owned infrastructures. Investors are advised to monitor the uptake of DTCC’s service post-launch, the timely execution of BNY Mellon’s pilots, and the practical utilization of tokenized collateral in live trading scenarios.
