Tokenized Treasuries for non-US investors: how they work, who can buy and the risks

Tokenized Treasury products are fund shares or notes backed by short-term US government debt, with ownership recorded on a blockchain. Most admit non-US investors only through professional-investor tests or licensed local distributors, and they add issuer, smart-contract and redemption risks that bills at a broker do not carry.

Key takeaways

  • A tokenized Treasury product is a fund or note that holds short-term US government debt and records its owners on a blockchain. You own a claim on the issuer, not the bills, so its legal home, custodian and redemption terms decide how safe the holding is and how it is taxed.
  • Access depends on the wrapper: BUIDL is a private fund with a $100,000 minimum, USDY excludes the US and Canada and needs professional status in many markets, and FOBXX is aimed at US residents.
  • The token is a record, not a bearer asset. A transfer agent or administrator keeps the official register, only approved wallets can hold most tokens, and the operator can correct or block transfers.
  • Exits usually run through the issuer on business days, often into the USDC stablecoin or a bank wire, and some products allow no trading between holders at all.
  • Next to bills held at a broker, a token adds smart-contract, issuer, stablecoin and regulatory risk in return for round-the-clock transfers. Local rules decide whether you may hold one.

Tokenized Treasury funds put a dollar money market fund inside a crypto wallet. You hold a token rather than a line on a broker statement, and with many products you can pass it to another approved holder at any hour of the day.

For investors outside the United States, the draw is a dollar yield without a US bank account. The catch is that most of these products are private placements or offshore notes with strict entry rules, and the token sits on top of the bills rather than replacing them. This guide explains the structures, who can buy the main examples, what they cost, how you get money back and how they compare with bills bought through a broker. Local rules decide whether you may hold one and how it is taxed, so check with your securities regulator first; the invest-from-abroad hub collects the US rules that apply to every route.

What are tokenized Treasuries?

They are shares in a fund, or notes from a company, that hold short-term US government debt and record who owns them on a public blockchain.

Staff at the US Securities and Exchange Commission described two families in a statement on January 28, 2026. In the first, the issuer itself puts its securities in token form, so moving the token moves the security on the issuer's own register. In the second, an unrelated firm wraps someone else's security, either by holding it in custody and issuing a token against it or by issuing its own linked note or swap. The staff added that holders of the second kind may be exposed to the wrapper's bankruptcy, and that the token format does not change how securities law applies. The statement is staff guidance with no legal force, but it is a useful map.

The market is growing but still modest. The tracker rwa.xyz listed 119 tokenized Treasury products worth $14.21 billion on November 2, 2026, about 4% less than a month earlier. Ondo's USDY was the largest at $2.4 billion, followed by Circle's USYC and BlackRock's BUIDL at about $2.2 billion and $2.1 billion. For background, see how tokenized bonds differ from traditional bonds and the introduction to on-chain US T-bills; how blockchain works covers the ledger itself.

How is a tokenized Treasury fund structured?

A typical fund has a manager, a custodian bank and an administrator like any money fund, plus a transfer agent that runs the blockchain register.

LayerWhat it doesExample

BlockchainRecords or mirrors who holds each tokenStellar by default for FOBXX, with seven other networks on request
DistributorChecks eligibility and takes subscriptionsA placement agent for BUIDL; licensed platforms in Hong Kong for ChinaAMC

The register is where products differ most. Franklin Templeton's FOBXX prospectus says its transfer agent keeps the official record of shares on a blockchain-integrated system: a permissioned setup on public networks, with a whitelist of approved wallets built into the smart contract and under the agent's sole control. The ChinaAMC USD Digital Money Market Fund in Hong Kong works the other way round. Its official register is an off-chain book kept by the administrator, the tokens on Ethereum represent those shares, and cash settles off the blockchain. In both cases the operator can fix an error or an unauthorized transfer by adding a new transaction rather than deleting the old one.

What sits inside varies too, and the label can mislead. BUIDL invests all its assets in cash, Treasury bills and repurchase agreements, and FOBXX keeps at least 99.5% in government securities, cash and fully backed repos. USDY, a note rather than a fund, may be secured by short-term Treasuries, shares of a US Treasury ETF or bank demand deposits, depending on when the tokens were issued. The ChinaAMC fund, which trackers group with Treasury products, can hold deposits and money market paper from banks and governments worldwide, with up to 100% in Greater China. Read the holdings, not the category.

Who can buy tokenized Treasury funds outside the US?

It depends on each product's legal wrapper, and most are closed to ordinary retail investors outside a few markets with licensed local distributors.

The thresholds are high. BUIDL relies on a US exemption that lets a fund skip registration if its buyers are qualified purchasers, which for an individual means owning at least $5 million of investments. Its July 2026 SEC filing lists a $100,000 minimum, far below the $5 million BlackRock announced at launch in March 2024, but it remains a private fund sold through one placement agent. USDY is open only to people outside the United States, and the issuer asks residents of restricted markets to prove they pass local tests: two of three criteria, including a €500,000 portfolio, in the European Economic Area; an HK$8 million portfolio in Hong Kong; and accredited status, such as S$1 million of net financial assets, in Singapore.

Retail access exists mainly where a local regulator has authorized a product for sale through licensed firms. The ChinaAMC fund sells its tokenized classes to Hong Kong retail investors only through distributors licensed by the Securities and Futures Commission, and the investor holds the tokens through the distributor's account rather than a personal wallet. FOBXX shows the opposite case: its $20 entry point is aimed at US residents, and with very limited exceptions the fund is not offered elsewhere. Whatever a product's own rules say, your country's securities and foreign-exchange laws apply on top.

How do custody and wallets work?

You either hold the token in a wallet the transfer agent or a custodian controls, or in your own wallet once the agent approves its address.

FOBXX gives each new investor a wallet on the Stellar network that the transfer agent creates and secures, holding the private key on the investor's behalf. An investor can use a self-managed wallet instead, but only with the agent's approval, and only wallets the agent created or approved can hold shares. BUIDL launched with several crypto custodians and a choice of how to hold the tokens, again limited to pre-approved investors. In the Hong Kong fund, the distributor holds the tokens as nominee in wallets kept with the token custodian, a Standard Chartered bank, so the retail investor never handles a private key.

Each model moves a risk rather than removing it. A hosted wallet depends on the agent's security and service. A self-managed wallet puts the key on you, and the Hong Kong fund's documents warn that a lost or stolen key can mean theft or lost access. Because the register is permissioned, the operator can usually freeze or reverse a bad transfer, which protects you from errors but also means a third party can block your holding, for example to comply with sanctions. Custodial vs non-custodial wallets explains the trade-off in general terms.

How do redemptions and transfers work?

Most products redeem through the issuer, not on an exchange, so getting cash back depends on its dealing days, cut-off times and payment methods.

  • BUIDL aims for a stable $1 per token and pays the daily accrued income as new tokens each month. Holders can transfer tokens at any hour to other pre-approved investors, and BlackRock warns that the $1 value may not hold at all times.
  • USDY comes in two forms: the standard token rises in price as interest accrues, while rUSDY stays at $1 and adds tokens instead. Redemptions go to the issuer for USDC, or for dollars wired only to a bank account outside the United States.
  • FOBXX lets whitelisted holders send shares to each other at any time, and a transfer completes once the blockchain confirms it. The fund stresses that this is not a public market: it does not match buyers and sellers, and a transfer need not happen at net asset value.
  • The ChinaAMC fund deals daily through its distributors, reinvests all income, and allows no transfers between holders and no secondary trading.

Two practical points follow. Round-the-clock transfers are not round-the-clock cash, because turning tokens into bank money still depends on the issuer's business days and on the banks that move the wire. And where the exit currency is USDC, you hold a stablecoin for a while and need a way to turn it into bank money. The stablecoin table shows the largest coins by market value, and stablecoin yield vs bank interest compares holding coins with holding deposits.

What does a tokenized fund cost compared with buying bills?

The fund fee is only part of the cost, because converting money into and out of the token and paying network fees can matter as much.

Published fees in the table above run from 0.16% to 0.26% a year, and private funds set theirs in offering documents. The example below uses round assumptions to show how the pieces add up.

Worked example: $50,000 for a year: bills at a broker versus a tokenized fund

Assumptions, not quotes: short-term bills yield 3.80% for the year, the broker charges a $25 commission, the tokenized fund charges 0.20% a year, converting dollars to USDC and back costs 0.10% each way, and network fees total $5.

StepBills at a brokerTokenized fund
Gross yield on $50,000$1,900$1,900
Fund feeNone−$100
Commission or conversion costs−$25−$102
Network feesNone−$5
Net gain$1,875$1,693
Net yield3.75%3.39%

The token route costs about $182 more here, mostly from getting in and out. A holder who already keeps dollars as USDC skips the conversions and nets about $1,795, or 3.59%, which is why these funds mostly attract people who already hold stablecoins.

The bill yield itself moves every day: today's T-bill rates shows the current figure for each term, and how money market funds work explains how a fund's yield relates to the bills it holds.

How are tokenized Treasuries taxed for non-US investors?

US tax depends on where the issuer is set up, and your home country taxes the income or gain under its own rules.

A US-registered fund such as FOBXX pays dividends. Its prospectus says non-US investors may face 30% withholding, or a lower treaty rate, on ordinary income dividends, while interest-related dividends and short-term capital gain dividends are generally exempt. It also warns that the shares may be subject to US estate tax and that holders need the right tax certification to avoid 24% backup withholding; for individuals that is usually the form covered in Form W-8BEN explained. A fund or note issued outside the United States, such as BUIDL or USDY from the British Virgin Islands, generally pays its holders without US withholding, and shares of a non-US company generally fall outside the US estate; the US estate tax guide for non-residents covers thresholds and treaties.

Home-country treatment is the bigger question. Your tax authority may treat a token as a crypto-asset, a fund share or a debt security, and the answer changes how income and gains are taxed and reported. An accumulating token, whose price rises instead of paying out income, may be taxed only when sold in some countries and every year in others. Foreign asset reporting can apply as well, as covered in reporting US investments at home. Tax rules change, so check with a tax adviser where you live before you buy.

How do tokenized Treasuries compare with owning bills?

Bills held at a broker are US government debt kept in custody for you; a token is a claim on a fund or company that owns bills.

FeatureBills at a brokerTokenized fund or note
What you ownTreasury bills held in your accountShares of a fund, or a note from its issuer
Who stands behind itThe US governmentThe issuer, whose assets include government debt
Smallest amountLow; set by the auction minimum and the brokerFrom USD 1 to $5 million, by product and network
TransfersThrough the broker during market hoursAny hour between approved wallets; redemptions on dealing days
PriceMoves slightly with rates, then face value at maturityA $1 target or a rising price, neither guaranteed
EligibilityAny investor a broker acceptsProduct rules plus local law; often professional investors only
US estate taxNot US property when held directlyDepends on where the issuer is set up
Extra risksBroker failure and custodySmart contract, issuer, transfer agent, stablecoin and regulatory risk

For most non-US investors who can open a brokerage account, bills or a bill fund are simpler and, on the example above, cheaper; Treasury bills for non-US investors covers those routes. The token case is strongest for holders who already keep dollars as stablecoins and want them in a regulated fund without leaving the blockchain.

What are the risks of tokenized Treasuries?

The bills inside are backed by the full faith and credit of the US government; the risks come from the layers on top.

  • Smart-contract and network risk. Code bugs, a network split or a processing delay can stall subscriptions and redemptions or leave on-chain and off-chain records out of step, risks the ChinaAMC fund lists in its key facts.
  • Issuer and operator risk. You rely on the issuer, custodian, transfer agent and distributor all working. A token wrapped by a third party adds that firm's own bankruptcy risk, as the SEC staff noted.
  • No deposit protection. These are investments, not deposits. The Hong Kong fund states that buying its shares is not the same as placing money on deposit and that repayment is not guaranteed.
  • Liquidity risk. Redemptions follow the issuer's dealing days, some products allow no transfers at all, and private transfers between holders can happen at prices away from net asset value.
  • Stablecoin risk. If you enter or leave through USDC, you rely on that coin holding its dollar value and on a platform willing to convert it.
  • Regulatory risk. Rules for tokenized securities are still forming in the US, Hong Kong and elsewhere, your own country may restrict crypto-assets or offshore funds, and operators can freeze wallets to meet sanctions rules.
  • Rate risk. Yields fall when the Federal Reserve cuts rates, and Treasuries themselves can lose value before maturity, as are Treasuries risk-free explains.
  • Impostor tokens. Fake tokens with familiar names circulate, so take the contract address from the issuer's own documents; crypto scams shows the common patterns.

What should you check before buying a tokenized Treasury fund?

Work through the legal wrapper, the holdings, your eligibility and the exit route before you look at the yield.

Before buying a tokenized Treasury product

  • Who issues the token, where it is incorporated and which regulator supervises it.
  • What it holds: only Treasuries, or also repurchase agreements, deposits and other money market paper.
  • Whether you qualify under its rules, and whether your country's securities and exchange-control laws allow it.
  • The minimum, the yearly fee and the cost of converting money in and out.
  • How redemptions work: dealing days, cut-off times, payout in USDC or by wire, and which banks it will pay.
  • Who holds the private key, and what the operator can do if a key is lost or stolen.
  • How your country taxes the income and gains, and whether US withholding or estate tax applies.
  • The official contract address, copied from the issuer's documents.

If the answers point to something plainer, holding US dollars abroad compares bank accounts, money funds, bills and stablecoins, and currency risk on US investments explains what the dollar itself can do to your returns.

Frequently asked questions

Are tokenized Treasuries the same as owning Treasury bills?+

No. You own shares in a fund, or a note issued by a company, that in turn holds bills, repurchase agreements or sometimes bank deposits. Your claim is on that issuer; the US government stands behind only the bills inside.

Can a retail investor outside the US buy one?+

Sometimes. A few products are authorized for retail sale through licensed local firms, such as a Hong Kong fund with a USD 1 minimum, but most global products sell only to professional, accredited or qualified investors.

What happens if the blockchain or smart contract fails?+

The official register of most funds is kept by a transfer agent or administrator, either off the blockchain or on a system it controls, so records can be corrected or rebuilt. Subscriptions and redemptions may still be delayed meanwhile.

Do tokenized Treasury funds pay the full T-bill yield?+

No. The fund fee, 0.16% to 0.26% a year in the funds here that publish one, comes out first, and converting money into and out of the token can cost as much again.

Is the yield taxed in the United States?+

It depends on the issuer. A US-registered fund may withhold 30% or a treaty rate on ordinary dividends, while a fund or note issued outside the US generally pays without US withholding. Your home country taxes it either way.
