Treasuries on-chain: Wall Street quietly pilots tokenized T-Bill ETF shares
One of the safest and most tightly supervised corners of global finance is edging onto blockchain rails. A major issuer of U.S. Treasury exchange-traded funds has asked regulators for permission to move part of its share registry onto a blockchain — without changing how investors buy, sell, or hold the fund in their brokerage accounts.
F/m Investments, manager of the roughly $6.3 billion US Treasury 3-Month Bill ETF (ticker: TBIL), has filed an application with the Securities and Exchange Commission (SEC) seeking approval to tokenize a portion of its existing ETF shares. The filing was submitted on January 21 and, if cleared, would mark the first time an ETF issuer officially receives the green light to record some of its shares as blockchain-based tokens.
Crucially, the proposal is deliberately conservative in design. The ETF’s underlying portfolio of three‑month U.S. Treasury bills would remain unchanged, as would its ticker symbol, trading venue, and overall structure. From the perspective of a typical investor placing an order through a broker, nothing about TBIL’s day-to-day trading mechanics would look different.
Instead, the shift would occur behind the scenes in the fund’s share registry. F/m Investments is asking to maintain two forms of the same ETF shares: conventional book‑entry shares and tokenized versions recorded on a blockchain. Both would be economically identical, carrying the same fees, rights, risks, and disclosures under the existing regulatory framework. In other words, tokenized shares would not be a new product, but a new way of recording ownership of the product that already exists.
Alexander Morris, CEO of F/m Investments, has framed the initiative as both inevitable and incremental. According to him, tokenization is coming to securities markets regardless of whether this particular application is approved. The firm’s move is less about inventing a new asset class and more about testing how the infrastructure of Wall Street can adapt to digital ledgers while still operating firmly within the regulatory perimeter.
If regulators sign off, short‑term U.S. Treasuries — the archetypal “risk‑free” asset in traditional finance — would become a live experiment for blockchain-based recordkeeping in a market that is deeply embedded in the global financial system. This would represent a significant shift in how blockchain is used: not as a parallel system built in defiance of rules, but as a technology adopted on regulators’ terms to modernize core market plumbing.
The TBIL initiative is not an isolated curiosity. It is part of a broader, accelerating effort to bring traditional financial assets, often referred to as “real‑world assets” (RWAs), onto blockchains through tokenization. Over the past year, some of the largest names in finance have moved from pilot projects to commercial offerings in this space.
Large asset managers have started to launch tokenized investment funds that run on public blockchains. One of the most high-profile examples is a digital liquidity fund operated on Ethereum, which has grown rapidly and demonstrated that regulated, yield‑bearing products can attract substantial capital in tokenized form. Meanwhile, a major global bank has introduced a tokenized money‑market fund targeted at institutional investors, enabling faster settlement and programmability while keeping the product fully compliant with existing fund regulations.
Traditional market infrastructures are also positioning themselves for a tokenized future. The New York Stock Exchange has signaled its ambition to extend equity and ETF trading into a near 24/7 model by building a blockchain-based venue for tokenized versions of listed stocks. The idea is to marry the around‑the‑clock dynamics of crypto markets with the safeguards of regulated securities exchanges, potentially blurring the line between “traditional” and “digital” trading hours.
Custody and servicing giants are not standing on the sidelines either. State Street, one of the world’s largest custodians, has launched a dedicated digital-asset platform aimed at supporting tokenized securities and other blockchain-based instruments. Its push underscores a simple reality: institutional adoption of tokenization will not scale without the participation of the firms that already safeguard and administrate trillions of dollars of conventional assets.
Tokenization is also influencing corporate treasury strategies. In Latin America, for instance, OranjeBTC has built what is described as the region’s largest corporate bitcoin treasury in response to chronic currency instability. While that initiative is focused on digital assets rather than tokenized securities, it highlights how organizations are exploring alternative, blockchain-connected instruments to hedge macroeconomic risk and diversify reserves.
What makes TBIL’s case particularly important is its regulatory posture. Rather than issuing a new, separate “on-chain” fund or pushing trading onto a crypto exchange, F/m Investments wants to keep all investor interactions inside the familiar ecosystem of brokers, clearing firms, and regulated exchanges. The blockchain layer would function as an additional, verifiable share ledger — a technological upgrade to the back office, not a revolution in how investors place orders.
If implemented successfully, such a model could address some of the long-standing inefficiencies of securities settlement. Blockchain-based records, in theory, offer near‑instant reconciliation, greater transparency for auditors and regulators, and reduced operational risk tied to mismatched ledgers across multiple intermediaries. For an asset class as large and critical as U.S. Treasuries, even marginal improvements in settlement efficiency and error reduction could translate into meaningful cost savings.
At the same time, the cautious design of TBIL’s tokenization experiment reflects the constraints of the current legal framework. U.S. securities law still presumes layered intermediaries — transfer agents, custodians, broker‑dealers — each with defined responsibilities and liabilities. Replacing or bypassing them wholesale with self‑custodied tokens is not on the table for a mainstream ETF. Instead, tokenization here is being explored as an internal modernization tool that coexists with the established infrastructure.
The move also raises strategic questions for regulators. If supervised, regulated tokenization of familiar products like T‑Bill ETFs proves technically sound and operationally reliable, it could provide a template for other funds and asset classes to follow. Such a template would give authorities more direct influence over how blockchain technology is integrated into capital markets, rather than forcing them to respond to unsanctioned experiments conducted entirely outside the traditional system.
For investors, the immediate impact of this specific filing is likely to be subtle. TBIL’s performance, risk profile, and use cases — providing highly liquid exposure to short‑term Treasuries — would not change simply because some shares are recorded on-chain. Most investors might never directly interact with the tokenized representation at all, especially if they continue to hold TBIL through conventional brokerages and custodians.
Over the longer term, however, experiments like this could lay the groundwork for new features. Tokenized shares, once standardized and widely accepted, could be used in programmable financial contracts or integrated more easily into decentralized finance protocols, allowing for new forms of collateralization, automated lending, or cross‑platform settlement. Those possibilities remain speculative for now but are clearly part of the broader vision animating the RWA tokenization trend.
There are, of course, risks and open questions. Cybersecurity becomes even more central when ownership records are placed on blockchains, and responsibility for safeguarding private keys and smart contracts must be clearly allocated. Legal interpretations around what constitutes the “definitive” record of ownership — the traditional transfer agent’s books or the blockchain ledger — will need to be harmonized and tested in practice, including in scenarios of disputes or errors.
Operationally, firms must ensure that tokenization does not create parallel, inconsistent systems of record. The promise of blockchain is a single, synchronized ledger; the danger, if implementations are poorly designed, is yet another layer of complexity that has to be reconciled with existing databases. Regulators will likely scrutinize any tokenized ETF structure to ensure that investor protections are at least as strong as in the traditional setup.
Despite these challenges, the direction of travel is clear. From tokenized liquidity funds and money‑market products to blockchain venues for tokenized stocks and digital-asset custody platforms, the financial industry is systematically probing how real‑world assets can live in both traditional and blockchain-native formats. F/m Investments’ TBIL initiative adds short‑term Treasuries to that list and does so from the heart of the regulated ETF ecosystem.
If the SEC ultimately approves the application, TBIL could become a reference point for how to bring one of the world’s most conservative instruments into the tokenization era without disrupting existing investor behavior. If the application is denied or heavily constrained, it will still provide valuable signals about how far regulators are currently willing to go in integrating blockchain technology into mainstream securities markets.
Either way, the filing underscores a turning point: tokenization is no longer a theoretical talking point or a niche experiment confined to startups and crypto‑native platforms. It is becoming a strategic priority for large asset managers, banks, exchanges, and infrastructure providers who see blockchain not as a replacement for Wall Street, but as the next layer of its technological stack. TBIL’s proposed tokenized shares are one of the first tests of what that future might actually look like in practice.
