Ondo Finance OUSG USDY: How Each Token Earns Its Yield

Written by Priyanka Rao, RWA Markets Writer. Reviewed by Thomas Vance, Tokenized Securities Analyst. Updated August 26, 2026.

Ondo Finance OUSG and USDY are the platform’s two yield products, and each earns its return from the assets that sit behind the token rather than from anything the blockchain itself creates. OUSG draws on short-term US Treasury exposure. USDY combines short-term Treasuries with bank deposits. In both cases the yield is variable and historical, never a promise. This guide explains where the return comes from and why it moves.

What backs Ondo Finance OUSG and where does its yield originate?

OUSG earns its yield from short-term US Treasuries. The tokenized fund holds Treasury exposure largely through BlackRock’s tokenized BUIDL fund, and the interest those instruments generate is what flows through to the value of the token. Historically this has been associated with a yield around five percent, a figure that is variable and not promised.

Short-term Treasuries are among the most familiar interest-bearing instruments in traditional finance. They pay a return that reflects prevailing short-term rates set in the broader market. When OUSG holds exposure to these instruments through a managed fund structure, the token effectively passes the fund’s earnings to holders, minus the costs of running that structure.

The reason a figure like five percent should be handled with care is that it is a snapshot. Short-term rates rise and fall, and the yield the fund earns rises and falls with them. A number cited last quarter is a description of the past, not a commitment about what the fund will earn next quarter. That is the difference between reporting a yield and promising one.

It is also worth being precise about what OUSG is. It is a tokenized fund, not an SEC-registered ETF and not a bank account. The yield originates in the underlying Treasury exposure and is shaped by the fund’s structure, so understanding the backing is the only reliable way to understand where the return comes from.

How does USDY’s backing add bank deposits to the mix?

USDY is backed by short-term US Treasuries and bank deposits, so its yield originates from both sources. The token is designed to hold near a dollar of value while accruing yield from that combined backing. Because bank deposits sit alongside Treasuries, USDY’s yield mechanics are not identical to OUSG’s even though both rely on short-term government debt.

Adding bank deposits to the backing changes the composition of what generates the return. Deposits and Treasuries can carry different rates and different characteristics, and the blend is part of how USDY is structured as a dollar-denominated yield instrument. The token is meant to reflect the yield accruing on this mix rather than to sit at a fixed peg.

This combined backing is one reason USDY and OUSG can display different yields at the same moment. They are not two labels for the same fund. Each has its own asset composition, its own costs, and its own design for how value reaches the holder, so a difference in reported yield is expected rather than surprising.

As with OUSG, any USDY yield figure is historical and variable. The design goal of staying near a dollar while accruing yield does not remove the fact that the underlying rates move. USDY is also closed to US persons, which is a separate eligibility fact but a reminder that the product’s structure and its distribution rules travel together.

Why are the yields variable rather than promised?

The yields are variable because they come from real assets whose rates change. Short-term Treasury rates move with market conditions and monetary policy, and bank deposit rates move too. Neither OUSG nor USDY manufactures a fixed return; each passes through what its backing earns, so the yield rises and falls rather than staying at a set level.

This is a structural point, not a caveat added for caution’s sake. A promised rate would require someone to absorb the gap whenever the underlying assets earned less than promised. These products are instead designed to reflect the earnings of their backing. When short-term rates fall, the yield these tokens can pass through tends to fall as well, and the reverse holds when rates rise.

Because of this, the honest way to describe any figure is as historical and variable. A yield quoted with a date describes a past period. Extending that number into the future as if it were guaranteed misrepresents how the products work. Reading yield figures with this framing protects a researcher from mistaking a snapshot for a commitment.

How do OUSG and USDY compare on yield mechanics?

The two products share Treasury exposure but differ in backing, structure and audience. OUSG is a tokenized Treasury fund for qualified participants. USDY blends Treasuries with bank deposits and is closed to US persons. Both carry variable, historical yields. The table below summarizes how each earns and reflects its return.

Yield aspect	OUSG	USDY
Primary backing	Short-term US Treasuries via BUIDL	Short-term Treasuries and bank deposits
Yield source	Interest on Treasury exposure	Interest on Treasuries plus deposits
Rate behavior	Variable with short-term rates	Variable with underlying rates
How value reaches holder	Reflected in the tokenized fund	Accrues while near a dollar
Nature of any figure	Historical, not promised	Historical, not promised

Read the table as a description of mechanics, not a ranking. The row that matters most is the last one: for both tokens, any figure is a historical description rather than a forward promise. The differences in backing explain why the two can report different yields, but the variability applies equally to both.

Nothing in the comparison implies that one product will earn more than the other in the future. Past differences reflect past conditions and structures. Because the underlying rates move, the relationship between the two yields can change over time, which is one more reason to treat any single figure as a snapshot.

How can you research a current yield figure responsibly?

You research a yield figure responsibly by finding the date it refers to, confirming which token it describes, tracing it to the backing, checking it against the official source, and recording it as variable rather than promised. This routine keeps a past number from being mistaken for a guarantee. The steps below walk through it.

Step 1: Find the date attached to the figure

Locate the date a yield figure refers to, because a yield without a date tells you nothing about whether it still applies today. A number that looks precise but lacks a date is effectively unverifiable.

Step 2: Identify which token the figure describes

Confirm whether the number describes OUSG or USDY, since the two have different backing and their yields are produced in different ways. A figure attached to the wrong token leads to a wrong conclusion.

Step 3: Trace the figure to the backing

Relate the yield to its source by checking whether it reflects Treasury exposure, and for USDY also bank deposits, rather than an arbitrary target set by a promotion. A yield that cannot be traced to real backing deserves suspicion.

Step 4: Confirm the figure against the official source

Check the number against the official Ondo source rather than a third-party post, because secondary figures are often outdated or rounded. Treat social posts and aggregators as pointers, not as the record.

Step 5: Record it as variable, not promised

Write down the figure with a note that it is historical and variable, so you never mistake a past rate for a guaranteed future return. The caveat is part of the fact, not an optional add-on.

What can cause the yield to change over time?

The main driver is the level of short-term interest rates, which sets what Treasuries and bank deposits earn. Beyond that, changes in a fund’s structure or costs, shifts in the mix of backing, and broader market conditions all feed into the yield a token can pass through. None of these are under a holder’s control.

Because short-term rates respond to monetary policy and market conditions, a period of falling rates tends to pull these yields down, while rising rates tend to lift them. This is the same dynamic that affects money-market instruments generally, and tokenizing the exposure does not change the underlying cause. The token simply reflects what its backing earns.

Structural factors matter too. Costs associated with managing a fund, the specific composition of the backing, and operational details can all influence the net yield reaching a holder. For USDY, the presence of bank deposits adds another moving part. For a researcher, the practical takeaway is that yield is an output of conditions and structure, which is exactly why it cannot be promised in advance.

Frequently asked questions

Does holding USDY mean I own bank deposits directly?

No. USDY is backed by a mix of short-term Treasuries and bank deposits, but holding the token is a claim on that structured backing, not direct ownership of a specific bank account. The backing is what allows the token to accrue yield.

Why can two Treasury-backed tokens show different yields?

OUSG and USDY do not have identical backing or structure. USDY combines Treasuries with bank deposits, the funds are managed differently, and each product has its own costs and mechanics, so the yield each passes through can differ even when both rely on short-term government debt.

Is a yield figure the same as a guaranteed interest rate?

No. A yield figure for OUSG or USDY is historical and variable. It reflects what the underlying assets earned over a past period and moves with prevailing short-term rates, so it should never be read as a fixed or promised rate you will receive going forward.

Do these tokens pay out cash or grow in value?

The mechanism depends on the token’s design. USDY is designed so that value accrues within the token while it stays near a dollar, rather than sending a separate cash payment. Always confirm the current distribution mechanics for each product on the official source.
