How Do Tokenized US Treasuries Work for Institutional Investors?

Why Tokenized US Treasuries Became the Largest Real RWA Segment

Of every asset class being put on-chain, short-dated US government debt moved fastest. The product is simple to explain and simple to value: a token that represents a claim on a portfolio of Treasury bills, paying the holder the same 4-5% yield those bills earn, settling in seconds instead of two business days. Demand followed the rate environment. When on-chain dollars sat idle in non-yielding stablecoins while T-bills paid over 4%, tokenizing the T-bill closed an obvious gap.

The scale is now material, not theoretical. According to RWA.xyz, BlackRock's USD Institutional Digital Liquidity Fund (BUIDL) crossed $2 billion in assets. Ondo Finance, Franklin Templeton's BENJI, OpenEden, and Superstate together pushed the tokenized-Treasury total past $5 billion on-chain. This is the segment institutions point to when they argue that real-world asset tokenization has moved from pilot to production.

“The value of tokenized US Treasury products surpassed $5 billion in 2025, up from under $800 million at the start of 2024, making it the fastest-growing tokenized real-world asset category outside of stablecoins.”

This guide explains how these products actually work: how a tokenized Treasury is issued compliantly, how yield reaches the holder, how redemption settles, who is allowed to buy, and where the model breaks. It is written for the institutions on both sides of the trade — the issuers deciding how to structure a product, and the treasuries and funds deciding whether to hold one.

How Does Compliant Issuance of a Tokenized Treasury Work?

Compliant issuance wraps the T-bills in a regulated vehicle, then mints tokens against fund shares with eligibility enforced on-chain. The sequence is fund formation, custody of the underlying bills with a qualified custodian, a transfer agent maintaining the investor registry, and a permissioned token contract that mints and burns only for allowlisted wallets.

In practice most US products use one of two regulatory structures. The first is a Rule 3(c)(7) private fund limited to qualified purchasers — the path BlackRock BUIDL took, distributed through Securitize as transfer agent. The second is a registered structure or an SEC-cleared arrangement for broader access, which Franklin Templeton pursued for BENJI after multi-year engagement with the SEC. Non-US-facing products such as Ondo USDY rely on Regulation S and offshore structuring to reach non-US investors without US registration.

“BUIDL is issued as shares of a fund that invests 100% of its total assets in cash, US Treasury bills, and repurchase agreements, with each token representing one share priced at a stable $1 and daily dividends accrued to holders.”

The token contract itself is where compliance becomes code. A permissioned standard such as ERC-3643 or a comparable allowlist model checks every transfer against the investor registry: a transfer to a wallet that is not verified reverts on-chain, not after the fact in a compliance review. This is the same enforcement pattern used across regulated RWA issuance, and it is why investor identity has to be established before a token can ever land in a wallet. The upstream KYC and AML onboarding process for RWA investors feeds the allowlist that the token contract reads.

How Do Redemption and Settlement Work for Tokenized Treasuries?

Redemption burns the holder's tokens and releases the corresponding cash or stablecoin, often same-day where an instant-redemption facility exists. BUIDL, for example, added a Circle-operated smart contract that lets holders swap into USDC around the clock, decoupling exit speed from banking hours and the T-bill settlement cycle.

Two settlement paths coexist. The traditional path routes a redemption through the fund administrator, who sells or matures T-bills and wires fiat back on a T+0 or T+1 cycle bounded by the custodian's banking cut-off. The on-chain path uses a pre-funded liquidity buffer — held in a stablecoin — so a holder can exit instantly during market hours and the buffer is topped up from the underlying portfolio later. The instant path is the headline feature, but it is capped by the size of the liquidity buffer; a redemption larger than the buffer falls back to the slower traditional cycle.

Secondary transfers are the other half of the liquidity story. Because transfer restrictions persist at the token level, a holder cannot simply sell to any counterparty on an open market — the buyer must already be on the allowlist. This is a structural constraint that shapes how deep secondary liquidity can get, and it is why the design of compliant secondary-market liquidity for RWAs matters as much as the primary issuance for large holders who may need to exit before maturity.

Who Are Tokenized Treasuries For, Who Should Avoid Them, and When Do They Break?

Tokenized Treasuries fit institutions that want yield-bearing, on-chain cash with same-day settlement — corporate treasuries, crypto-native funds, and DAOs managing reserves. They are a poor fit for open retail distribution, for holders needing instant fiat off-ramps in every jurisdiction, and for anyone who cannot pass the allowlist. They break under redemption stress, chain or bridge failure, and de-pegging of the stablecoin used for on-chain settlement.

Who it is for

• Corporate treasuries with idle dollars that want a yield-bearing, same-day-liquid instrument — a use case explored in depth in our guide on RWA tokenization for corporate treasuries.
• Crypto-native funds and DAOs holding large stablecoin reserves that are currently earning nothing.
• Fintechs and exchanges that want to offer a yield product without building fund infrastructure from scratch.

Who it is NOT for

• Open retail distribution — allowlist gating and, for many products, high minimums or non-US-only access rule out the general public.
• Holders needing guaranteed instant fiat exit in any currency — instant redemption is capped by the on-chain liquidity buffer and the underlying banking rails.
• Investors seeking duration or credit yield — these are short-dated government instruments; the yield is the T-bill rate, not a credit premium.

When it breaks

The failure modes are specific and worth stress-testing before allocating:

• Redemption crunch: if instant-redemption demand exceeds the stablecoin liquidity buffer, holders fall back to the slower traditional T+0/T+1 cycle, exactly when they wanted speed.
• Settlement-stablecoin de-peg: a product that pays out in a stablecoin inherits that stablecoin's peg risk at the moment of exit.
• Chain or bridge failure: a token spread across multiple chains via bridges carries bridge risk; an outage can freeze transfers even while the underlying bills are fine.
• Allowlist lockout: a compliance status change (sanctions hit, lapsed accreditation) can suspend a holder's transfer rights mid-hold.

None of these are reasons to avoid the asset class — they are the diligence checklist. A fuller treatment of the category-level exposures sits in institutional RWA tokenization risks.

The Bottom Line on Tokenized US Treasuries

Tokenized US Treasuries work because they take the most familiar, lowest-risk instrument in institutional finance and give it 24/7 settlement and on-chain composability, while passing the underlying yield to the holder. The mechanics that make them safe — qualified custody, token-level eligibility, daily attested NAV, and controlled redemption — are also the mechanics that separate a compliant security from a stablecoin.

For issuers, the question is no longer whether the model works — BUIDL, BENJI, and Ondo settled that — but how to launch one without rebuilding the compliance stack that the first movers spent years and tens of millions assembling. For allocators, the question is fit: tokenized Treasuries are excellent yield-bearing on-chain cash for verified institutions, and a poor fit for anyone who needs open access or guaranteed instant fiat exit. Match the product's access rules and yield model to how you actually intend to hold it, and the largest real RWA segment does exactly what it says on the label.
