The tokenized fixed-income market has matured rapidly. In 2024, tokenized U.S. Treasuries led the way as the first institutional-grade real-world assets brought onchain, with products like BlackRock's BUIDL fund crossing $500 million in AUM. By 2026, the landscape has expanded to include a second major asset class: mortgage-backed securities. For investors evaluating where to allocate onchain capital, the comparison between these two tokenized instruments is now one of the most consequential decisions in digital fixed income.
This article provides a detailed head-to-head comparison of tokenized MBS and tokenized treasuries across every dimension that matters: yield, risk, liquidity, market size, institutional adoption, retail accessibility, and portfolio use cases. The goal is to give investors the information they need to make informed allocation decisions between these two foundational onchain asset classes.
Overview: Two Asset Classes, One Infrastructure
Both tokenized MBS and tokenized treasuries use the same fundamental infrastructure: blockchain-based settlement, smart contract compliance, qualified custody of underlying assets, and digital token representations of traditional securities. The difference lies entirely in the underlying asset.
Tokenized treasuries represent direct ownership of U.S. government debt obligations. They are the lowest-risk fixed-income instrument available, backed by the full faith and credit of the United States. Treasury yields are set by Federal Reserve policy and reflect the risk-free rate in the global financial system.
Tokenized MBS represent ownership of pools of residential mortgages, most commonly agency pass-through securities guaranteed by Fannie Mae, Freddie Mac, or Ginnie Mae. Agency MBS carry an implicit (or, in Ginnie Mae's case, explicit) government guarantee on principal and interest payments. They yield more than treasuries because they compensate investors for the complexity of mortgage cash flows, particularly prepayment risk.
Yield Comparison: The MBS Spread
The most significant difference between these two asset classes is yield. As of early 2026, tokenized treasury products generally offer yields in the range of 4.2% to 4.8% APY, closely tracking the underlying Treasury rates minus a small management fee. Tokenized agency MBS products, by contrast, offer yields in the range of 5.5% to 6.5%, depending on the coupon, vintage, and prepayment assumptions of the underlying pool.
This 100 to 175 basis point spread is the primary reason investors consider tokenized MBS over treasuries. The spread exists because MBS cash flows are more complex than treasury cash flows. Treasuries pay a fixed coupon on a fixed schedule and return principal at a fixed maturity date. MBS distribute both interest and principal monthly, and the timing of principal return is uncertain because homeowners can prepay their mortgages at any time.
For context, on a $1 million allocation, the yield difference between tokenized treasuries at 4.5% and tokenized MBS at 6.0% translates to approximately $15,000 in additional annual income. Over a five-year holding period, that compounds to a meaningful performance differential, particularly for yield-focused strategies.
The MBS spread over treasuries has historically averaged 100 to 175 basis points for agency pass-throughs. This spread compensates for prepayment risk, not credit risk, since agency MBS carry a government guarantee on timely payment of principal and interest.
Risk Comparison
Risk is where the comparison becomes nuanced. Both asset classes are considered high-quality fixed income, but they carry different types and degrees of risk.
Credit Risk
Tokenized treasuries carry effectively zero credit risk. They are direct obligations of the U.S. government, and the probability of a U.S. sovereign default is treated as negligible in virtually all financial models.
Tokenized agency MBS also carry very low credit risk, though not quite zero. Fannie Mae and Freddie Mac provide an implicit government guarantee, meaning the U.S. government is expected to stand behind their obligations but is not legally required to do so (unlike Ginnie Mae, which carries an explicit full faith and credit guarantee). In practice, the 2008 conservatorship of Fannie and Freddie demonstrated that the government will support these entities, and agency MBS are treated as near-risk-free by most institutional investors.
Prepayment Risk
This is the key risk that differentiates MBS from treasuries. Prepayment risk is the possibility that homeowners will pay off their mortgages early, typically through refinancing when interest rates decline. When prepayments accelerate, MBS investors receive their principal back sooner than expected, often at a time when they can only reinvest at lower rates.
Treasuries have no prepayment risk. The government pays interest on schedule and returns principal at maturity. This predictability is a major reason treasuries are the benchmark risk-free asset.
For tokenized MBS, prepayment risk is identical to the traditional market, but the onchain environment offers a potential advantage: real-time prepayment analytics delivered through oracle feeds can give investors more timely visibility into pool behavior than the monthly factor reports used in traditional markets.
Duration and Interest Rate Risk
Both asset classes are sensitive to interest rate movements, but in different ways. Treasury duration is fixed and known at purchase. A 5-year Treasury note has a duration of approximately 4.5 years, and its price sensitivity to rate changes is straightforward to calculate.
MBS duration is variable and depends on prepayment behavior. When rates fall, prepayments accelerate, and MBS duration shortens (investors get principal back faster). When rates rise, prepayments slow, and MBS duration extends (investors are stuck holding a lower-yielding asset longer). This phenomenon, called negative convexity, means MBS underperform treasuries in both strongly rising and strongly falling rate environments, but outperform in stable rate environments due to their higher yield.
Side-by-Side Comparison
The following table summarizes the key differences between tokenized MBS and tokenized treasuries across the dimensions that matter most to investors.
| Dimension | Tokenized Treasuries | Tokenized MBS |
|---|---|---|
| Yield (2026) | 4.2% – 4.8% | 5.5% – 6.5% |
| Credit Risk | Effectively zero (full faith & credit) | Near-zero (agency guarantee) |
| Prepayment Risk | None | Yes — borrowers can refinance early |
| Duration | Fixed, known at purchase | Variable, depends on prepayments |
| Cash Flow | Semiannual coupon + principal at maturity | Monthly interest + principal |
| Market Size | ~$27 trillion | ~$15 trillion |
| Tokenized AUM (2026) | $3B+ across multiple issuers | Early stage, growing rapidly |
| Settlement | Atomic (onchain) | Atomic (onchain) |
| Best For | Capital preservation, liquidity, collateral | Yield generation, income portfolios |
| Retail Access | Widely available | Emerging via platforms like OWNR |
Liquidity and Trading
Tokenized treasuries currently have a significant liquidity advantage. With over $3 billion in tokenized AUM across products from BlackRock, Franklin Templeton, Ondo Finance, and others, treasury tokens benefit from deeper order books, more market makers, and greater DeFi composability. Many tokenized treasury products are already integrated as collateral in major lending protocols and as backing for stablecoins.
Tokenized MBS are earlier in their liquidity development. The traditional MBS market is highly liquid, with the Federal Reserve and major banks trading billions daily, but that liquidity has not yet been fully replicated onchain. As platforms like OWNR build out MBS tokenization infrastructure and attract institutional participants, onchain MBS liquidity is expected to grow substantially. The sheer size of the $15 trillion underlying market provides a deep reservoir of assets waiting to be brought onchain.
Market Size and Opportunity
The U.S. Treasury market is approximately $27 trillion in outstanding securities, making it the largest and most liquid debt market in the world. The U.S. MBS market is approximately $15 trillion, making it the second-largest fixed-income market. Together, these two markets represent over $40 trillion in assets.
Despite MBS being the smaller of the two, the tokenization opportunity in MBS may actually be larger. The Treasury market already functions with high efficiency: electronic trading, tight bid-ask spreads, and near-universal institutional access. The improvements from tokenization, while meaningful, are incremental.
The MBS market, by contrast, still relies heavily on OTC dealer networks, phone-based trading for certain tranches, and T+2 or T+3 settlement cycles. The inefficiency gap is larger, which means the improvement from tokenization is more dramatic. Additionally, the MBS market has historically been inaccessible to retail investors due to high minimums and complexity, creating a massive untapped demand pool that tokenization can unlock.
Institutional Adoption
Tokenized treasuries are ahead in institutional adoption. The entry of BlackRock, Franklin Templeton, and other major asset managers into the tokenized treasury space has provided institutional validation and brought significant capital onchain. These products are increasingly used as onchain cash equivalents, collateral for derivatives, and yield-bearing alternatives to stablecoins.
Institutional adoption of tokenized MBS is building but remains earlier-stage. The complexity of MBS cash flows, the need for specialized prepayment analytics, and the regulatory considerations around mortgage-related securities have meant a longer development timeline. However, the institutions that trade traditional MBS (banks, insurance companies, pension funds, REITs) manage trillions of dollars and have strong economic incentives to adopt more efficient settlement and access infrastructure. As MBS tokenization platforms mature, institutional flows are expected to follow.
Retail Accessibility
One of the most compelling aspects of tokenization is its ability to democratize access to institutional asset classes. Tokenized treasuries have already achieved broad retail accessibility, with multiple platforms offering fractional treasury exposure with minimums as low as $100.
Tokenized MBS represent an even bigger retail opportunity precisely because the traditional market has been so inaccessible. In the conventional MBS market, minimum trade sizes are typically $1 million or more, and accessing specific pools requires broker-dealer relationships and specialized trading systems. Tokenization can reduce minimums to $1,000 or less, giving retail investors access to an asset class that has historically delivered strong risk-adjusted returns but was reserved for institutional portfolios.
This is a core part of OWNR's mission: making the yield and diversification benefits of MBS available to every investor, not just those with seven-figure allocations.
Use Cases: When to Choose Each
The choice between tokenized MBS and tokenized treasuries depends on the investor's objectives, risk tolerance, and portfolio strategy. Below are the primary use cases for each.
Choose Tokenized Treasuries When:
You prioritize capital preservation above yield optimization
You need highly liquid onchain collateral for DeFi strategies or margin requirements
You want a predictable, fixed payment schedule with no cash flow variability
You are building a cash management strategy and need a yield-bearing alternative to stablecoins
You require the lowest possible credit risk in your fixed-income allocation
Choose Tokenized MBS When:
You are seeking higher yield and are comfortable with prepayment variability in your cash flows
You want monthly income distributions rather than semiannual coupon payments
You are building a diversified fixed-income portfolio and want exposure beyond government debt
You believe the MBS tokenization market is early and want to establish positions before broader institutional adoption
You want exposure to the U.S. housing market through a high-quality, government-backed instrument
Consider Both When:
Many sophisticated investors will allocate to both asset classes. A common approach is to use tokenized treasuries as a liquidity reserve and onchain cash equivalent, while deploying tokenized MBS as a higher-yielding core holding for income generation. This barbell strategy captures the MBS yield premium on the majority of the portfolio while maintaining instant liquidity through the treasury allocation.
The Portfolio Construction Perspective
From a portfolio construction standpoint, tokenized MBS and tokenized treasuries are complementary, not competing. They serve different functions within a fixed-income allocation:
Treasuries: The Liquidity Layer
Tokenized treasuries function as onchain cash equivalents. They offer the highest liquidity, lowest risk, and broadest composability with DeFi protocols. They are ideal for funds that need to deploy and redeploy capital quickly, or for investors who want yield on idle stablecoins without taking meaningful risk.
MBS: The Yield Layer
Tokenized MBS function as the income engine of an onchain fixed-income portfolio. Their 100 to 175 basis point spread over treasuries compounds into significant outperformance over time, while their agency guarantee keeps credit risk at near-treasury levels. They are ideal for investors with a longer time horizon who can tolerate cash flow variability in exchange for higher total return.
Combined: The Complete Onchain Bond Portfolio
Together, tokenized treasuries and tokenized MBS give investors access to the two largest and most important segments of the U.S. fixed-income market, entirely onchain, with atomic settlement, programmable compliance, and fractional access.
Where the Market Is Headed
The tokenized treasury market proved that institutional-grade fixed income can work onchain. The tokenized MBS market is the next frontier, bringing a larger yield opportunity and a more transformative efficiency improvement to a market that desperately needs it. As both markets grow, the lines between onchain and traditional fixed income will continue to blur.
Investors who understand both asset classes and their onchain implementations are positioned to build portfolios that would have been impossible just two years ago: diversified, yield-optimized, instantly settled, and accessible at any scale.

Tokenized treasuries gave onchain investors access to the risk-free rate. Tokenized MBS give them access to meaningful yield above it, with comparable credit quality and a $15 trillion addressable market. The complete onchain bond portfolio includes both.
Frequently Asked Questions
What is the yield difference between tokenized MBS and tokenized treasuries?
Tokenized MBS typically offer 100 to 175 basis points of additional yield over tokenized treasuries. As of early 2026, tokenized treasury products yield approximately 4.2% to 4.8%, while tokenized agency MBS products yield approximately 5.5% to 6.5%, depending on coupon, vintage, and prepayment assumptions. This spread compensates investors for prepayment risk and the slightly more complex cash flow structure of mortgage-backed securities.
Are tokenized MBS riskier than tokenized treasuries?
Agency tokenized MBS carry an implicit government guarantee through Fannie Mae, Freddie Mac, or Ginnie Mae, making their credit risk comparable to treasuries. However, MBS introduce prepayment risk, meaning borrowers can refinance or pay off mortgages early, which affects the timing and amount of cash flows. Treasuries have no prepayment risk and offer a fixed, predictable payment schedule. Both carry platform-level risks related to custody and smart contract infrastructure.
Can I invest in both tokenized MBS and tokenized treasuries?
Yes. Many investors build diversified onchain fixed-income portfolios that include both tokenized treasuries for stability and liquidity, and tokenized MBS for higher yield. A balanced allocation allows investors to capture the MBS yield spread while maintaining a portion of their portfolio in the most liquid, lowest-risk government instruments. Platforms like OWNR are designed to support allocation across multiple tokenized asset classes.
Which is better for passive income: tokenized MBS or tokenized treasuries?
Tokenized MBS generally produce higher monthly income due to their yield premium over treasuries. MBS also distribute both interest and principal each month, resulting in higher monthly cash flow than treasury coupons alone. However, the income stream from MBS is less predictable due to prepayment variability. Treasuries offer lower but more predictable income. The better choice depends on whether you prioritize yield or cash flow predictability.
What is prepayment risk in tokenized MBS?
Prepayment risk is the possibility that homeowners in the underlying mortgage pool will pay off their loans early, typically through refinancing when interest rates fall. When prepayments accelerate, MBS investors receive principal back sooner than expected, often at a time when reinvestment rates are lower. This risk does not exist in treasuries, which have fixed maturity dates. Tokenized MBS inherit the same prepayment characteristics as traditional MBS, though onchain analytics can provide more transparent, real-time prepayment data to help investors monitor pool behavior.
