Tokenized US Treasuries — How BlackRock BUIDL and Franklin OnChain Crossed $5B in 2026

The tokenization of real-world assets was described as a future use case for blockchain for most of the industry's history. In 2026, it is a present reality. The tokenized US Treasury market crossed $5 billion in total value locked in early 2026, anchored by two institutional products: BlackRock's BUIDL fund on Ethereum and Franklin Templeton's OnChain US Government Money Fund running on Stellar and Polygon. These are not experimental products — they are registered securities with regulatory oversight, managed by the world's largest asset managers, and they are demonstrating that blockchain infrastructure can reduce the friction of institutional fixed income investment in measurable ways.

## BlackRock BUIDL: The Institutional Entry Point

The BlackRock USD Institutional Digital Liquidity Fund (BUIDL) launched on Ethereum in March 2024 through a partnership with Securitize, a regulated digital asset securities firm that handles transfer agency and tokenization infrastructure. BUIDL invests in US Treasury bills, repo agreements, and cash, targeting a stable $1 NAV with daily yield accrual.

BUIDL grew to become the largest tokenized treasury fund by assets within months of launch, reflecting BlackRock's institutional distribution network. Qualified investors holding BUIDL tokens receive daily yield accruals in the form of additional tokens. The tokens are ERC-20 standard but restricted to KYC-verified wallets — a permissioned token model that satisfies securities regulations while maintaining EVM compatibility.

The EVM compatibility is the key DeFi integration point. BUIDL tokens can be used as collateral in DeFi protocols that have integrated them, enabling yield-bearing collateral in lending protocols — a significant improvement over non-yielding stablecoins that represent the current collateral standard in most DeFi lending markets.

## Franklin Templeton OnChain US Government Money Fund

Franklin Templeton launched its blockchain-native money market fund in 2021 — earlier than any major competitor — initially on Stellar and later expanded to Polygon. The FOBXX fund uses Stellar's fast and low-cost settlement layer to record share ownership, with the blockchain serving as the official transfer agent record rather than a parallel system.

This distinction matters: Franklin Templeton's approach treats the blockchain ledger as the primary record of ownership, not a secondary representation. This enables near-instant settlement and reduces the administrative overhead of traditional transfer agency operations. The fund has demonstrated that tokenized money market funds can operate within existing securities law frameworks while achieving meaningfully lower operational costs than traditional fund administration.

## Yield Advantage in the High-Rate Environment

The significance of the $5B tokenized treasury market is partly a function of the interest rate environment. With Fed funds rate elevated above 4% through 2024–2025, Treasury bills offered yields of 4–5% — dramatically higher than the near-zero yields on USDC or USDT stablecoins. Tokenized treasury products enabled DeFi participants and institutional holders to earn Treasury yields on assets held on-chain, eliminating the opportunity cost of holding stablecoins for liquidity purposes.

This yield differential drove the market's rapid growth. Ondo Finance and Superstate, two DeFi-native protocols offering tokenized treasury exposure, took different approaches: Ondo's OUSG targets institutional investors with compliance requirements while Superstate's USTB aims for more permissionless access within regulatory constraints. Together with the institutional products from BlackRock and Franklin Templeton, they created a segmented market serving different customer profiles.

## Where Growth Comes From

The $5B tokenized treasury market represents approximately 0.02% of the $25 trillion US Treasury market. The growth opportunity is substantial, but it depends on resolving several friction points. The permissioned token model required by securities regulations limits composability with the broader DeFi ecosystem. Interoperability between different tokenized treasury products across different blockchains requires bridge infrastructure that introduces additional risk. And institutional adoption at scale requires regulatory clarity that the SEC has provided only incrementally.

The SEC's guidance on digital asset securities under Gary Gensler and subsequently under the more crypto-sympathetic 2025 administration has created more workable compliance pathways for tokenized securities. If the current trajectory continues, the tokenized treasury market reaching $50B by 2027 is a realistic projection — still a fraction of the total market, but large enough to establish blockchain settlement infrastructure as a standard component of institutional fixed income operations.
