The Tokenisation of the Treasury Market: A Capital-Markets Revolution Hiding in Plain Sight

On 29 April 2026, the aggregate value of tokenised US Treasury products crossed 15.07 billion dollars. Eighteen months earlier the same figure was a rounding error in the Securities Industry and Financial Markets Association’s monthly bulletin. Before explaining why that number matters, it is worth pausing on a word that the financial press now deploys as if its meaning were settled. Tokenisation. Almost nobody outside a trading floor could define it, and the gap between how often the term is used and how rarely it is understood is itself part of the story.

What Tokenisation Actually Is. Strip away the vocabulary and the idea is mundane. To tokenise an asset is to issue a digital record of ownership, a token, on a blockchain, the shared electronic ledger that also underpins cryptocurrencies. The token is not a new asset. It is a claim on an old one. In the case at hand, the underlying asset is a share in a fund that holds US Treasury bills, the short-term IOUs of the American government and the safest, most liquid dollar instrument in existence. The actual bills still sit in custody inside the conventional financial system. What changes is the wrapper and, more importantly, the rails. A traditional fund share settles the next business day, only during market hours, passed along a chain of custodians and clearing houses that each take a turn and a fee. A tokenised share settles in seconds, at any hour including weekends, and can be moved by software without a human in the loop. Tokenisation, then, is less a financial invention than a plumbing upgrade. It does not change what you own. It changes how fast, how cheaply and how continuously you can move it.

That distinction is why the Treasury market is the prize. Every other financial instrument on earth is priced against the US government’s borrowing rate. Build a faster, always-on rail for the one asset that anchors all the others, and you have not built a curiosity. You have built a parallel circulatory system for the dollar. The growth has been roughly twenty-fold since BlackRock’s BUIDL fund launched in March 2024, and the holders have shifted decisively from crypto-native corporate treasury desks to regulated fund administrators, prime brokers and stablecoin issuers. The American Treasury market, which has long resented any infrastructure newer than a Bloomberg terminal, now runs a parallel rail that settles in seconds and trades on weekends. The establishment is no longer experimenting with this rail. It is operating it. The thesis is simple. Tokenisation will be the largest non-AI structural change in global capital markets between 2026 and 2030, precisely because it touches the instrument every other instrument is measured against.

The Issuer Stack. A handful of regulated funds dominate. BlackRock’s USD Institutional Digital Liquidity Fund, tokenised by Securitize and known by its ticker BUIDL, remains the anchor. Its assets crossed 1 billion dollars in March 2025 and peaked near 2.9 billion in mid-2025 before share migration across nine blockchains split the float, the total pool of tokens issued and in circulation. Franklin Templeton’s BENJI is the on-chain version of a money market fund, a vehicle that holds only ultra-safe short-term debt and is designed never to lose value; it carries a 15 basis-point fee, that is fifteen hundredths of one percent, and roughly 850 million dollars in assets as of March 2026. Ondo Finance’s OUSG and its retail USDY sleeve sit around 1.2 billion combined. Circle’s USYC, acquired from Hashnote in January 2025, surged on the back of Circle’s distribution and overtook BUIDL in late January 2026 to claim the lead. Superstate’s USTB rounds out the top tier near 650 million. The category is concentrated, regulated and adult. Five names hold roughly 80 percent of the float.

The Stablecoin Reserve Pipe. The mechanism that turns these fund wrappers into a genuine Treasury-market force runs through stablecoins. A stablecoin is a crypto token engineered to hold a constant value of one dollar, kept stable by a reserve of cash and Treasury bills held against every coin issued. Those reserves are enormous. Tether held roughly 127 billion dollars in Treasury bills as of the second quarter of 2025, about 65 percent of its backing. Circle held about 80 percent of USDC’s reserves in bills through a BlackRock-managed fund custodied at BNY. Together the two issuers owned around 180 billion dollars of bills at mid-year 2025, roughly 3 percent of the entire bill market. The GENIUS Act, signed by President Trump on 18 July 2025 after lopsided votes in both chambers, accelerates the trend by mandating full reserve backing in cash or short-term Treasuries plus monthly public disclosure. The practical effect is that every dollar of stablecoin growth now funnels almost mechanically into demand for government bills, and a rising share of that demand is expressed as on-chain holdings of products like BUIDL or USYC rather than direct purchases. The US Treasury has, without announcing it, acquired a new captive buyer roughly the size of a mid-tier foreign central bank.

The Wall Street Plumbing. The institutional plumbing has caught up. JPMorgan’s blockchain platform, now under the Kinexys umbrella, had processed over 1 trillion dollars in notional transactions, the total face value of funds moved across the platform, by April 2025, including intra-day repo and tokenised deposit settlement with BlackRock and Siemens. Goldman Sachs’ GS DAP, being spun out as a standalone entity targeted for mid-2026, has settled tokenised bond issuances for sovereign and supranational clients. The Depository Trust and Clearing Corporation, the firm that sits at the centre of US securities settlement, received an SEC no-action letter in December 2025 clearing it to offer a tokenisation service, with limited production trades scheduled for July 2026. The Canton Network, a permissioned blockchain backed by JPMorgan, Goldman Sachs and roughly 600 other institutions, claims more than 6 trillion dollars in tokenised assets routed across it. These are not pilots. They are production systems with regulatory cover and named counterparties.

The Regulatory Permission Slip. The legal scaffolding was assembled in roughly twelve months. SEC Chairman Paul Atkins, who replaced Gary Gensler, launched Project Crypto in mid-2025 and codified the doctrine that a tokenised security is still a security, while most free-floating network tokens are not. His November 2025 keynote in Philadelphia previewed exemptions tailored to on-chain offerings and a safe harbour for tokenised funds. The Commodity Futures Trading Commission, under Acting Chairman Caroline Pham, permitted tokenised real-world assets, including tokenised Treasuries, to serve as eligible margin collateral, the cushion a trader must post to back a position, and launched a digital-assets pilot in December 2025. The Federal Reserve signalled that banks should not be disadvantaged in the digital-asset business. The through-line across all three regulators is the same: a permissioned, federally supervised pipe for tokenised dollar assets, built deliberately and from the top down.

The Always-On Run Vulnerability. The risk that should occupy policymakers is not adoption. It is mismatch. The token side of these funds settles instantly and can be redeemed around the clock, including on a Sunday. The underlying Treasury bill market trades only from roughly 08:00 to 15:00 New York time on weekdays. A redemption shock that hits a tokenised fund on a Sunday evening in Asia has nowhere to express itself in the cash market until Monday morning in New York. In between, the authorised participants and prime brokers, the institutions that create and redeem fund shares and stand between the token and the underlying market, absorb the gap on their own balance sheets. That is fine in calm weather. In a stressed Sunday, with a regional-bank rumour or a geopolitical shock, the gap itself becomes the trade. The Bank for International Settlements has flagged this asymmetry twice, and its Project Agora cross-border pilot is exploring synchronised settlement windows as a partial remedy. Until the underlying market trades round the clock, the tokenised wrappers will act as a liquidity transformer of a kind the Treasury market has never run before. That is an exposure to monitor, not to celebrate.

The Verdict. Tokenised Treasuries have crossed the threshold from curiosity to infrastructure. A 15 billion dollar float on the current trajectory becomes a 50 to 75 billion dollar float by the end of 2027, and the marginal buyer of a six-month bill in 2028 will increasingly be a piece of software executing a stablecoin redemption rather than a primary dealer reaching for yield. The capital-markets establishment has chosen its rails, the SEC and CFTC have chosen permissiveness, and the GENIUS Act has chosen short-duration government paper as the de facto reserve asset of the digital dollar. The remaining question is not whether tokenisation reshapes the Treasury market. It is whether the market’s trading hours, settlement windows and dealer balance sheets adapt fast enough to contain the always-on tail the new infrastructure is now generating. Bet on adoption. Hedge the mismatch.
