## What the 6.8% Rate Actually Represents

![US Treasury Bills backing stablecoin protocol collateral with yield rate charts displayed](https://cdn.getmidnight.com/13448471d89a9cd8d7f71026a0334ec8/2026/09/usual-busd0-treasury-yield-analysis-after-h2-1.webp)

Usual's bUSD0 product is now advertising a 6.8% APY on approximately $503 million in total value locked. That rate marks a 2.38 percentage point increase from the previous quoted yield. The question readers ask is whether the new rate is sustainable and how much capital can be allocated safely.

The answer requires understanding what the 6.8% represents. It is not a single yield stream. The rate is a composite of base collateral yield generated from US Treasury Bills backing USD0, plus alpha yield distributed in USUAL governance tokens to bUSD0 holders. The base component is predictable and tracks the Treasury Bill market. The alpha component depends on token price performance and protocol emissions schedules.

As of September 28, 2026, the 1-year US Treasury rate stood at 4.53%. The 2-year was 4.94%. These are the baseline yields generated by the collateral backing every USD0 token. Any rate above that baseline is alpha yield paid in USUAL tokens, not yield generated by the underlying real-world assets.

This distinction matters because base yield is durable as long as the collateral remains sound. Alpha yield fluctuates with token price. If USUAL drops 30%, your effective APY drops with it. If emissions are reduced, the rate advertised to users falls even if collateral yield stays constant.

The 2.38pp increase could have originated from three sources: an increase in underlying Treasury rates, an increase in USUAL token emissions allocated to bUSD0 holders, or appreciation in USUAL token price that raised the dollar-denominated value of distributed rewards. Treasury rates have been stable in recent weeks, which suggests the increase is primarily driven by changes in token emissions or price.

## How the Protocol Generates and Distributes Yield

![Trader analyzing USUAL token distribution mechanics and alpha yield components on screen](https://cdn.getmidnight.com/13448471d89a9cd8d7f71026a0334ec8/2026/09/usual-busd0-treasury-yield-analysis-after-h2-2.webp)

Usual operates a two-token model. USD0 is the stablecoin, pegged to the dollar and backed 1:1 by real-world assets. bUSD0 is the bond product. Users lock USD0 for a fixed term to earn loyalty bonuses in the form of USUAL governance tokens.

Every USD0 token is backed by collateral that generates yield. The primary collateral asset is Hashnote USYC, which invests in reverse repurchase agreements and US government-backed securities. The protocol also accepts other collateral including eUSD0 (Euler USL deposits), USUALM, and additional RWA instruments. There is no fractional reserve and no leverage applied at the collateral layer.

The yield generated by this collateral is real revenue from real assets. It tracks the Treasury Bill market and is independent of USUAL token price. This is the base yield component. For a 1-year position, that base yield should approximate the 1-year T-bill rate, currently 4.53%.

The alpha yield layer is separate. USUAL tokens are distributed to bUSD0 holders as a loyalty incentive and as a mechanism to align long-term holders with protocol governance. The protocol has described USUAL as representing ownership of 100% of protocol revenue and as backed by cash flows generated from Treasury Bill yields. The token is designed to capture protocol value accrual over time.

The effective APY shown to users combines both streams. If base yield is 4.5% and alpha yield is 2.3%, the advertised rate is 6.8%. The sustainability of that 6.8% depends entirely on whether the alpha component holds. Base yield will track Treasury markets. Alpha yield will track USUAL token performance and emission schedules.

According to protocol documentation, daily USUAL emissions were approximately 1.35 million tokens per day following a disinflation event. The allocation to bUSD0 holders depends on the total amount of USD0 locked, the duration of the lock, and the protocol's reward distribution formula. If emissions are cut or if more capital enters bUSD0 pools, the per-user alpha yield declines.

There is also a rehypothecation mechanism at work. When users lock USD0 into bUSD0, the protocol employs 1:1 rehypothecation to maintain backing for free-floating USD0\. The system allows a maximum theoretical leverage of approximately 8.33x, calculated as 1 divided by (1 minus 0.88), where 0.88 is the loan-to-value ratio used in the Usual Stability Loan mechanism deployed on Fira.

This rehypothecation loop amplifies efficiency but also introduces execution complexity. If a large number of bUSD0 holders attempt to exit simultaneously and redemption demand exceeds the protocol's ability to unwind positions smoothly, secondary market discounts can emerge. This is what happened in January 2025.

## The January 2025 Depeg and What It Signals for Allocation Sizing

![Risk management dashboard displaying liquidity metrics and capital allocation sizing for stablecoin positions](https://cdn.getmidnight.com/13448471d89a9cd8d7f71026a0334ec8/2026/09/usual-busd0-treasury-yield-analysis-after-h2-3.webp)

On January 10, 2025, Usual changed the redemption terms for its bond product. The original structure allowed 1:1 redemption. The new structure introduced a dual-exit mechanism with a floor price.

The change was announced without extended notice. The market reacted immediately. USD0++ (the prior name for bUSD0) depegged to approximately $0.946\. One token was redeemable for about $0.94 in underlying collateral. USUAL token price dropped roughly 30% in the week following the announcement.

This event is the single most important data point for anyone evaluating allocation sizing at the 6.8% rate. The depeg was not caused by collateral failure. Every USD0 remained backed 1:1 by Treasury Bills and repo agreements. The depeg was caused by a governance decision that changed exit terms in a way the market had not priced in.

The implication is that governance and design risk are material. The protocol is attempting to coordinate stablecoin issuance, governance value accrual, staked-governance mechanics, bond products, and credit primitives simultaneously. That level of complexity creates surface area for unintended consequences.

Position sizing frameworks used by institutional desks start from worst-case drawdown, not from headline APY. The standard assumption is that each isolated risk (smart contract, depeg, governance) can produce a 10-30% drawdown. If two correlated risks activate at the same time, losses can exceed 30%.

The January 2025 depeg demonstrated a 5.4% immediate loss on redemption value, a 30% loss on USUAL token value, and secondary market illiquidity that prevented large holders from exiting without additional slippage. A user with $100,000 allocated would have faced a worst-case scenario in which redemption value dropped to $94,600 and the USUAL tokens earned as alpha yield lost 30% of their value overnight.

Given this precedent, conservative allocation to bUSD0 at any rate should not exceed 5-15% of total stablecoin-designated capital. Users with higher risk tolerance and shorter lock periods might allocate up to 25%, but only after testing exit liquidity on secondary markets.

Exit liquidity testing involves checking Curve and Pendle for bUSD0 trading pairs. Measure the depth at 1%, 3%, and 5% slippage. If you cannot exit your intended position size within 3% slippage, your position is too large. This testing should be repeated monthly because liquidity conditions change.

## Comparing the 6.8% Rate to Baseline Alternatives

The 6.8% rate needs to be evaluated against baseline alternatives that carry similar or lower risk. Several useful comparisons exist.

First, the risk-free rate. As of late September 2026, 1-year Treasuries pay 4.53%. That is the opportunity cost of capital with zero smart contract risk, zero depeg risk, and zero governance risk. The 2.27pp spread between 4.53% and 6.8% is the premium Usual offers for accepting protocol-layer risks.

Second, competing stablecoin yield products. [Other platforms are paying 3.8% to 9% APY on USDC, USDT, and DAI](https://altcoininvestor.com/how-to-earn-passive-income-stablecoins-2026/) through CeFi platforms, DeFi lending, and yield-bearing token structures. Platforms with comparable risk profiles include Aave USDC lending (currently around 3.5% to 4.2%), Compound V3 USDC (recently dropped from 5.36% to 3.29%), and other RWA-backed stablecoin products like Maple USDG at 4.96%.

The Usual rate of 6.8% is competitive but not an outlier. It sits above most large-venue lending rates but below the highest-risk DeFi strategies. The key differentiator is the alpha yield component. If USUAL token price remains stable or appreciates, the effective yield can exceed 6.8%. If USUAL declines, the realized yield will be lower.

Third, alternative allocation targets for the same capital. A user with $100,000 could deploy that capital to Aave USDC at 4% with near-perfect liquidity and minimal smart contract risk. The annual return would be $4,000\. The same capital deployed to bUSD0 at 6.8% generates $6,800 annually, a $2,800 premium. The question is whether that $2,800 compensates for the January 2025 depeg precedent, the rehypothecation complexity, and the USUAL token price exposure.

For users who already hold exposure to USUAL and believe in long-term protocol value accrual, the answer may be yes. For users seeking stable income with minimal volatility, the answer is probably no. The 6.8% rate is appropriate for a portion of stablecoin allocation, not the entire position.

## What Treasury Composition and Utilization Data Reveal

The sustainability of the 6.8% rate depends on the health of the protocol's treasury and the utilization rate of locked capital. Both can be tracked on-chain.

Usual's collateral is transparent. Every USD0 is backed by a basket of real-world assets including Hashnote USYC, eUSD0, USUALM, and other RWA instruments. The protocol documentation confirms that BNY Mellon provides institutional-grade custody for a portion of the collateral. The protocol has undergone more than 20 independent audits and operates an active bug bounty program.

Collateral composition can shift over time. The protocol initially relied exclusively on USYC from Hashnote but has stated plans to diversify into assets from Ondo and BlackRock. Diversification reduces single-issuer risk but introduces new counterparty exposures. Users should monitor the collateral breakdown using [protocol dashboards on DeFiLlama](https://defillama.com/protocol/usual?denomination=USD) to verify that no single asset dominates the reserve base beyond stated thresholds.

Utilization rate is the second key metric. Utilization measures the percentage of total USD0 that is locked into bUSD0 versus circulating freely. Higher utilization reduces available exit liquidity. If 90% of USD0 is locked into bUSD0 and a significant redemption wave begins, the protocol must unwind collateral positions rapidly to meet redemptions. This can trigger slippage in secondary markets and redemption delays.

The protocol's loan-to-value ratio is 0.88 with a liquidation threshold of 0.9999\. This means users can borrow against bUSD0 collateral at up to 88% of its value with near-certain liquidation if the value drops below the peg. The low liquidation threshold minimizes bad debt risk but also means that even small depegs can trigger cascading liquidations.

The borrow rate is 0% base plus a 0.10% annual protocol fee (10 basis points). The fee is immutable and cannot be changed by governance. This structure keeps borrowing costs low but also means the protocol cannot raise fees to reduce utilization during stress events.

Users allocating capital to bUSD0 should check current utilization weekly. If utilization exceeds 80%, allocation should be reduced or avoided entirely. At 60% to 70% utilization, allocation is reasonable but should be monitored. Below 50% utilization, the protocol has ample reserve capacity to handle redemptions without stress.

## Rate Durability and the USUAL Token Price Sensitivity

The 6.8% rate is durable only to the extent that the alpha yield component remains stable. The base yield tied to Treasury Bills will fluctuate with Federal Reserve policy and bond market conditions, but those changes are gradual and predictable. The alpha yield tied to USUAL token rewards is volatile and depends on factors outside the user's control.

USUAL token price declined approximately 30% in the week following the January 2025 redemption-term change. That decline translated directly into a reduction in realized APY for bUSD0 holders who were earning rewards in USUAL. A user who locked $100,000 into bUSD0 in early January expecting 8% annual yield (hypothetical pre-depeg rate) would have seen their USUAL-denominated rewards lose 30% of their dollar value within seven days.

Token price sensitivity is compounded by emissions schedules. If the protocol reduces daily USUAL emissions from 1.35 million tokens to 1 million tokens, the effective alpha yield drops by roughly 26% even if token price remains constant. If emissions remain stable but total locked USD0 increases from $500 million to $700 million, the per-dollar alpha yield drops by approximately 28%.

These mechanics mean that the 6.8% rate advertised today is not a locked-in return. It is a snapshot of current conditions. Users who enter at 6.8% may realize 8% if USUAL appreciates. They may realize 5% if USUAL declines or if TVL surges and dilutes per-user rewards.

Historical rate volatility in similar protocols provides a useful benchmark. Protocols offering hybrid base-plus-alpha yield structures have shown annualized rate standard deviations of 100 to 300 basis points. That means a 6.8% advertised rate could reasonably fluctuate between 5.8% and 7.8% over a 12-month period under normal conditions, and could drop below 5% or spike above 9% during periods of market stress or token price surges.

## Liquidity, Lock Periods, and Exit Strategy

Lock periods for bUSD0 vary by user selection. Longer locks earn higher loyalty multipliers and receive more USUAL rewards per dollar locked. Shorter locks offer flexibility but lower yields.

During the lock period, the user's capital is illiquid at the protocol level. The only exit option is through secondary markets on Curve, Pendle, or other venues where bUSD0 trades. Secondary market pricing can deviate from intrinsic value during volatility.

In the January 2025 depeg, bUSD0 (then USD0++) traded at a 5.4% discount to redemption value on secondary markets. Users who needed liquidity immediately were forced to accept that discount. Users who could wait until the lock period expired were able to redeem at the floor price set by the new dual-exit mechanism, which was closer to parity but still below 1:1.

Exit strategy for bUSD0 positions should be defined before entry. The strategy has three components: target exit date, acceptable slippage threshold, and fallback plan if secondary market liquidity evaporates.

Target exit date should align with lock expiry. Exiting early through secondary markets is acceptable only if slippage is below 1%. If slippage exceeds 3%, the cost of early exit erases most of the yield advantage over baseline alternatives like Aave USDC.

Acceptable slippage threshold depends on position size and yield duration. A user who has earned 6.8% for six months has captured 3.4% in realized yield. That user can tolerate up to 3% exit slippage and still outperform a 4% baseline alternative. A user who has earned 6.8% for two months has captured only 1.13% in yield and cannot tolerate more than 1% slippage without falling below the baseline.

Fallback plan should include monitoring protocol governance proposals, tracking utilization and reserve metrics weekly, and setting hard stops for capital withdrawal if utilization exceeds 80% or if governance proposes changes to redemption terms.

## When the 6.8% Rate Makes Sense and When It Does Not

The 6.8% bUSD0 rate makes sense for users who meet four conditions. First, they already have exposure to or conviction in USUAL token price appreciation. Second, they can tolerate 10% to 30% drawdown scenarios without forced liquidation. Third, they have tested exit liquidity on secondary markets and confirmed they can exit their position within acceptable slippage. Fourth, they are allocating no more than 5-15% of stablecoin-designated capital to the position.

Users who meet these conditions can treat bUSD0 as a hybrid yield-plus-governance speculation. The base yield provides downside protection. The alpha yield provides upside optionality. The combination is appropriate for a portion of an income-focused portfolio.

The 6.8% rate does not make sense for users seeking stable, predictable income with minimal volatility. It does not make sense for users who cannot monitor the position weekly. It does not make sense for users who have never tested secondary market exit liquidity. It does not make sense for users who would be forced to sell at a loss if a depeg event similar to January 2025 occurs again.

The rate also does not make sense for users who are unfamiliar with governance risk in complex DeFi protocols. Usual is coordinating stablecoin issuance, bond mechanics, credit primitives, and governance value accrual simultaneously. That level of ambition increases the probability of design errors, governance disputes, or unintended incentive misalignments.

For comparison, simpler alternatives like [USDC lending on Aave](https://altcoininvestor.com/best-stablecoin-yield-comparison/) or USDT deposits on centralized platforms carry lower rates but also lower complexity and lower governance risk. Users who prioritize simplicity and liquidity over maximum yield should choose those alternatives.

## What This Means for Allocation Strategy

The 2.38pp rate increase to 6.8% is a signal, not a destination. It tells you that the protocol has either increased USUAL emissions to bUSD0 holders, that USUAL token price has appreciated, or that underlying Treasury rates have shifted. The first two possibilities are more likely given recent rate stability in the Treasury market.

Allocation strategy should start from the worst-case scenario and work backward. The worst-case scenario is another governance change similar to January 2025, combined with a 30% USUAL token price drop and secondary market illiquidity. In that scenario, a $100,000 position could lose 5% to 10% of principal value before stabilizing.

Conservative allocation is 5% of stablecoin-designated capital. Moderate allocation is 10% to 15%. Aggressive allocation is 25%, but only for users who have backtested exit liquidity and can tolerate large drawdowns.

Allocation should be scaled over time, not deployed in a single transaction. Enter 50% of the intended position, monitor for two weeks, then add the remaining 50% if conditions remain stable. This staged entry reduces exposure to adverse selection and allows time to observe protocol behavior under current market conditions.

Rebalancing should occur quarterly or when the rate moves more than 100 basis points in either direction. If the rate drops from 6.8% to 5.8%, evaluate whether the new rate still justifies the risk. If the rate rises from 6.8% to 7.8%, evaluate whether increased demand is straining utilization and reserve capacity.

Diversification is mandatory. No more than 15% of total stablecoin capital should be allocated to any single protocol, regardless of advertised rate. The higher the rate, the more important diversification becomes. A portfolio earning 4.5% across five venues with minimal correlation is more durable than a portfolio earning 6.8% in a single venue with concentrated risk.

## The Takeaway

The 6.8% bUSD0 rate is a composite of Treasury Bill yield and USUAL token rewards. The base component tracks the risk-free rate. The alpha component tracks token price and emissions schedules. The January 2025 depeg demonstrated that governance decisions can change exit terms without extended notice and that secondary markets can discount bond tokens by 5% or more during stress.

Position sizing should reflect that precedent. Conservative users allocate 5-15% of stablecoin capital and test exit liquidity before deploying. Aggressive users may allocate up to 25% but only with weekly monitoring and hard stops for utilization and governance risk. The 2.38pp increase is real, but its durability depends on variables outside your control.

The rate is appropriate for users who want hybrid exposure to stablecoin base yield and protocol governance upside. It is not appropriate for users seeking stable, predictable returns with minimal complexity. Usual's treasury is transparent and well-audited, but the protocol's ambition introduces execution complexity that translates to governance risk.

If you are moving $100,000 from a 4.42% baseline to 6.8%, you are capturing an additional $2,380 per year. That premium compensates you for smart contract risk, depeg risk, USUAL token price exposure, and the possibility that governance changes exit terms again. The premium is worth accepting for a portion of your capital. It is not worth accepting for all of it.

## Frequently Asked Questions

### Is the 6.8% bUSD0 rate backed entirely by Treasury Bills?

No. The 6.8% rate is a composite of base T-bill yield (approximately 4.5% based on current 1-year Treasury rates) plus alpha yield paid in USUAL governance tokens. Every USD0 is backed 1:1 by real-world assets including Hashnote USYC, which invests in reverse repos and US government securities. The yield above the risk-free rate depends on USUAL token appreciation and protocol emissions, not just underlying collateral returns. This means sustainability is tied to token price performance, not collateral alone.

### What caused the 2.38pp rate increase to 6.8%?

Rate increases in Usual's bUSD0 product stem from two possible sources: changes in the underlying Treasury Bill yield environment or adjustments to USUAL token emission rates distributed to bUSD0 holders. As of late September 2026, the 1-year T-bill rate stood at 4.53%. Any yield above this baseline is alpha yield paid in USUAL tokens. If the protocol increased emissions per locked USD0 or if USUAL token price appreciated, the effective APY shown to users would rise even without collateral yield changes.

### How much capital can I safely allocate to bUSD0 at 6.8%?

Position sizing for yield-bearing stablecoins should start from worst-case drawdown, not expected APY. Institutional frameworks assume each isolated risk category (depeg, smart contract, governance) can produce a 10-30% drawdown, with larger losses if correlated risks fire simultaneously. Given Usual's January 2025 depeg precedent (USD0++ dropped to $0.946) and the complexity of its bond structure, conservative allocation is 5-15% of stablecoin-designated capital. Exit liquidity testing is mandatory. Check secondary market depth on Curve and Pendle before deploying large positions.

### What is the difference between USD0 and bUSD0?

USD0 is Usual's core stablecoin, a permissionless Liquid Deposit Token pegged to the dollar and backed 1:1 by US Treasury Bills and repurchase agreements. It is designed for payments, trading, and use as collateral. bUSD0 is the bond product where users lock USD0 for a fixed term to earn loyalty bonuses paid in USUAL governance tokens. bUSD0 holders gain directional exposure to protocol performance through token rewards but face lock periods and redemption structure changes, as evidenced by the January 2025 dual-exit mechanism shift.

### Did the January 2025 depeg affect bUSD0 safety?

Yes. On January 10, 2025, Usual changed bUSD0 redemption conditions from a guaranteed 1:1 ratio to a dual-exit method with a floor price. The token depegged to approximately $0.946, catching the market by surprise. This event demonstrated that governance design risk and redemption-mechanism changes can materially affect bUSD0 valuation independent of underlying collateral quality. Holders who sized positions without factoring governance-layer volatility experienced unexpected drawdowns. The incident remains relevant when evaluating current allocation sizing and exit strategy.
