S&P Dow Jones Indices tokenized its iBoxx U.S. Treasuries Index on the Canton Network on March 31, 2026. The company executed the move in partnership with Kaiko, a digital asset data infrastructure provider. Together, they issued the index as a native blockchain asset, making a widely used fixed-income benchmark available directly within smart contract environments. This is the first time a benchmark of this scale has been issued as a native blockchain token. The move reflects a broader shift in how Wall Street thinks about distributing financial data and infrastructure.
The iBoxx U.S. Treasuries Index tracks the performance of U.S. government bonds across multiple maturities. Asset managers and institutional investors use it as a reference point for pricing, valuation, and fund construction. It underpins bond ETFs and a broad range of institutional financial products. Bringing this index onchain means institutions can now access the benchmark directly through blockchain systems, rather than relying on conventional data feeds and licensing arrangements.

How the Tokenized Index Works
The index is issued as a non-fungible token on the Canton Network. Importantly, this token is not a tradeable investment product. Instead, it functions as a programmable data distribution mechanism for financial institutions. Kaiko aggregates, normalizes, and validates real-time market data, then feeds it into the onchain token structure.
The smart contract token embeds the index data alongside licensing rights, fee terms, and access control permissions. Kaiko’s team describes the approach as creating “a smart contract token that contains all of the index data,” with licensing and access control embedded directly into the contract structure. This eliminates the need for separate licensing agreements and manual data management processes. Customizable smart contract wrappers sit on top of the base token to handle use-case-specific terms, audit rights, and conditions. As a result, institutions can access and integrate the benchmark programmatically without managing those layers manually.
What Canton Network Is
Canton Network is a permissioned, privacy-enabled blockchain designed for institutional finance and regulated markets. Digital Asset Holdings built the network, and the Canton Foundation handles its governance. The network operates on a “network of networks” model, where each participating institution maintains its own ledger while connecting to others through a shared synchronization layer called the Global Synchronizer.
Canton uses Digital Asset’s Daml smart contract language, which supports atomic transactions and privacy-preserving settlement. Atomic transactions ensure that complex multi-party exchanges either complete in full or do not execute at all. This design addresses the privacy and compliance requirements that public blockchains cannot easily satisfy. S&P Global is a strategic investor in Digital Asset and an active participant on the Canton Network. Other backers and participants include Goldman Sachs, BlackRock, Citadel, Blackstone, Nasdaq, and more than 600 institutional validators.
What It Unlocks for Institutional Markets
Tokenizing a benchmark like the iBoxx U.S. Treasuries Index opens several practical capabilities. Institutions can configure smart contracts to trigger automatic collateral adjustments based on live index values. Asset managers can rebalance tokenized funds in real time as index data updates onchain. Settlement workflows can execute automatically upon index publication, bypassing T+1 delays and reducing counterparty risk.
Additionally, the always-on nature of blockchain infrastructure enables 24/7 index tracking, something traditional exchange-hour systems cannot support. Canton’s Global Collateral Network already demonstrated a live on-chain U.S. Treasury financing transaction earlier this year, showing the network can handle real institutional settlement flows. DTCC, which processes transaction activity measured in quadrillions of dollars daily, announced plans to tokenize DTC-custodied U.S. Treasury Securities on Canton, with a minimum viable product targeted for the first half of 2026. These developments collectively move the conversation from tokenization pilots to live market infrastructure.
The RWA Market Behind This Move
The tokenized U.S. Treasury market has grown rapidly, and this announcement fits a clear acceleration trend. Tokenized Treasury products now exceed $12.5 billion in total value, up from roughly $7.4 billion at mid-2025. Total real-world asset tokenization across all categories has reached $27.7 billion. BlackRock’s BUIDL fund alone exceeded $2.3 billion in tokenized value as of late 2025. McKinsey projects the broader RWA tokenization market could reach $2 trillion by 2030.
S&P Dow Jones Indices tracks more than 125,000 benchmarks used across global investment markets. The iBoxx tokenization is the first, and the companies said the approach could expand to other indices as institutional interest in onchain infrastructure grows. Kaiko’s existing role as a crypto market data provider positions it well to support additional index tokenizations. Together, S&P and Kaiko are establishing a model for how traditional benchmark providers can distribute data natively on institutional blockchains. This has implications well beyond Treasuries.
Why the Structure Matters
One detail sets this tokenization apart from other RWA announcements: the index itself is not being made investable. S&P and Kaiko are tokenizing the data layer, not the underlying securities. This distinction is important. It means the project is building the data plumbing that makes onchain financial products reliable, not replacing existing market structures directly.
By embedding licensing, access permissions, and compliance requirements directly into the token, S&P removes friction from the entire data supply chain. Institutions no longer need to manage separate agreements and manual verification processes for each product they build on top of the index. This approach could become a standard model for how benchmark providers operate in tokenized markets. Furthermore, it positions S&P as a foundational data layer for the next generation of institutional onchain infrastructure, not just a participant in it.
