Usual USD USD0: RWA-Backed Stablecoin, bUSD0 Bond Flywheel, and Liquidity Risk

TL;DR

Verdict: Usual USD (USD0) is a selective RWA-stablecoin watchlist, not core reserve collateral.
Why it matters: Usual tries to turn the stablecoin issuer into a community-owned onchain RWA balance sheet: USD0 is the dollar, bUSD0 is the bond product, sUSD0 is the savings wrapper, and USUAL/USUALx route value and governance back to participants.
The key risk: USD0 itself trades near peg, but much of the system's value is locked into bUSD0, a fixed-maturity bond token that currently trades below par and depends on USUAL emissions, redemption design, and secondary liquidity.
What would upgrade the view: Deeper USD0/USDC liquidity, a stable bUSD0 discount curve, transparent reserve dashboards, durable USUAL revenue distribution, and clean redemption behavior under stress.

Executive Summary

Usual USD (USD0) is the core stablecoin of Usual Protocol. The official documentation describes USD0 as a permissionless, fully collateralized stablecoin backed by tokenized U.S. Treasury Bills and repurchase agreements. Usual positions the protocol as a community-owned stablecoin issuer that routes protocol value to USUAL holders, USUALx lockers, and the DAO treasury rather than retaining reserve yield in a corporate issuer. Usual overview USD0 docs

The product is best understood as a stack:

Layer	Product	What It Does	Main Risk
Stablecoin	USD0	RWA-backed USD stablecoin	Redemption, collateral, liquidity
Savings	sUSD0	ERC-4626 vault where USD0 yield accrues through exchange rate	DAO yield allocation and wrapper liquidity
Bond	bUSD0	Fixed-maturity bonded USD0, formerly USD0++	Lock-up, discount, USUAL coupon, rt-bUSD0 liquidity
Governance / value capture	USUAL / USUALx	Governance, staking emissions, revenue switch	Token inflation, revenue durability, lock-up behavior

As of the June 23, 2026 snapshot, CoinGecko shows USD0 around rank #95, $0.999 price, about $553M market cap / FDV, $824K 24h volume, and about 553.6M circulating supply. DefiLlama tracks Usual USD at about $553.1M circulating, mostly on Ethereum, and classifies it as a fiat-backed peggedUSD asset. CoinGecko USD0 DefiLlama Stablecoins

The important nuance is bUSD0. CoinGecko shows Bond USD0 around $0.964, about $508M FDV, and 526.9M total supply. GoPlus shows the Ethereum USD0 token has about 553.5M total supply and that the bUSD0 contract holds roughly 526.8M USD0, or about 95% of the observed Ethereum USD0 supply in that API snapshot. CoinGecko bUSD0 GoPlus USD0

That makes Usual different from a simple stablecoin. The headline asset is USD0, but the economic engine is the conversion of USD0 into bUSD0, USUAL emissions, sUSD0 savings, and USUALx revenue distribution. My current view: selective watchlist, not core reserve collateral. USD0 is one of the more interesting RWA-backed stablecoin designs, but the bond flywheel and liquidity structure need to prove themselves across stress.

Research Question and Investment Relevance

The core research question:

Can Usual turn tokenized Treasury collateral into a durable community-owned stablecoin issuer, or does the model depend too heavily on bUSD0 lock-up, USUAL emissions, and thin secondary liquidity?

USD0 matters because the stablecoin market is splitting into several models:

Model	Examples	Value Capture	Main Weakness
Corporate fiat-backed stablecoins	USDT, USDC, PYUSD, RLUSD	Issuer captures reserve spread	Centralized issuer and bank/regulatory risk
DeFi-native credit stablecoins	GHO, crvUSD, DAI / USDS	Protocol borrow revenue and governance	Collateral and peg-management complexity
Synthetic dollars	USDe, USDf	Basis / strategy yield	CEX, custodian, strategy and redemption risk
RWA-backed community issuers	USD0, USYC-style wrappers	Treasury yield plus governance / revenue share	Access, liquidity, governance, product complexity

Usual is not only issuing a stablecoin. It is trying to tokenize the stablecoin issuer economics. That is more ambitious than just backing a dollar with T-bills, and it also creates more moving parts.

The docs say Usual was founded in France in 2022 and raised $17M across seed and Series A rounds, with investors including Binance Labs, Kraken Ventures, Galaxy Digital, IOSG Ventures, and OKX Ventures. The same official overview describes USD0 and USUAL as deployed across Ethereum, Arbitrum, Base, and BNB Chain, with Chainlink CCIP and LayerZero used for cross-chain infrastructure. Usual overview

USD0 Mechanics: RWA Collateral and Mint/Redeem Paths

USD0 is documented as a fiat-backed stablecoin model implemented through Usual Collateral Bridge Infrastructure (UCBI). UCBI connects permissioned RWA tokenizers with permissionless DeFi users. Permissioned users can deposit and redeem tokenized RWA collateral directly, while permissionless users can mint indirectly through USDC and collateral-provider matching. USD0 docs

Official docs list the main USD0 collateral design as follows:

Component	Documentation Claim	Investment Readthrough
Primary collateral	Tokenized Treasury Bills and repos	Lower credit/duration risk than volatile crypto collateral
Primary provider	Hashnote USYC	Provider and tokenizer concentration matters
Duration target	Portfolio average below 0.33 years	Limits rate sensitivity but does not remove redemption/liquidity risk
Insurance fund	0.33%-5.33% of USD0 supply in risk docs / USD0 docs	Helpful buffer, but needs observable balance and governance history
Direct redemption	USD0 can be redeemed for underlying tokenized collateral at par	Practical access depends on permissions and collateral rails
Indirect minting	USDC users rely on collateral providers / SwapperEngine	Permissionless UX depends on institutional CP liquidity

The official RWA collateral page says accepted collateral must be fully collateralized, low risk, transparent, and liquid, with portfolio duration below 0.33 years and redemption or sale within a maximum of 5 business days. It also says collateral is restricted to U.S. Treasuries, quasi-government debt, or cash, with corporate debt prohibited. RWA collateral docs

Hashnote USYC is identified as the first and primary collateral partner. The docs describe USYC as a short-duration yield fund using reverse repos and U.S. government securities, with BNY Mellon custody, Cohen and Co as auditor, NAV Consulting as fund administrator, and T+0 to T+1 settlement into USDC or PYUSD. RWA collateral docs

This is a serious collateral story. But it should still be analyzed like an RWA cash-management product: tokenizer risk, fund administrator risk, custody risk, settlement timing, governance controls, and redemption queues matter.

bUSD0: The Bond Product Is the Real Flywheel

bUSD0 is the bonded, yield-bearing form of USD0. The docs say bUSD0 was formerly USD0++ and was redesigned under UIP-12 in November 2025, introducing rt-bUSD0 as a separate early-exit right. The current bUSD0 series matures on June 11, 2028. At maturity, 1 bUSD0 redeems for 1 USD0 without rt-bUSD0. Before maturity, users can redeem at par only by recombining 1 bUSD0 + 1 rt-bUSD0. bUSD0 docs

That design cleanly separates principal, yield, and liquidity:

Token	Economic Meaning	Yield	Liquidity
USD0	Stablecoin claim	No native bond coupon	Redeem / sell near $1
bUSD0	Locked USD0 principal to maturity	Daily USUAL coupon unless in USL/UZR	Trades below or near par
rt-bUSD0	Early-exit right	No	Needed for pre-maturity par redemption

The current market confirms this is not just theoretical. CoinGecko shows bUSD0 around $0.964, and Dexscreener shows the main visible Ethereum bUSD0/USD0 Uniswap and Curve pools with roughly $3.7M liquidity each. bUSD0's discount is not a USD0 depeg; it is the market pricing of a June 2028 bond-like token, early-exit optionality, USUAL coupon risk, and liquidity risk. CoinGecko bUSD0 Dexscreener bUSD0/USD0 Uniswap Dexscreener bUSD0/USD0 Curve

This is why the asset should not be underwritten as "RWA-backed stablecoin = low risk." USD0 is the stablecoin; bUSD0 is a structured bond product whose market price can be below par until maturity.

sUSD0 and USUALx: Real Yield, Token Yield, and Revenue Routing

sUSD0 is the savings wrapper. The docs define it as a non-rebasing ERC-4626 vault where USD0 deposits receive sUSD0 shares and yield accrues through a rising exchange rate. Yield comes from the underlying collateral stack, and distribution parameters are adjustable by USUAL governance. sUSD0 docs

USUALx is the staking token. Users stake USUAL to receive USUALx; the USUALx-to-USUAL exchange rate appreciates as staking emissions accrue. The docs say USUALx holders receive 22% of all daily USUAL emissions, and basic staking has no mandatory lock-up, but unstaking currently carries a 10% fee distributed among remaining stakers, insiders, and DAO/protocol recipients. USUALx docs

The Revenue Distribution Module adds a second layer: only locked USUALx receives weekly USD0 revenue distributions through the Revenue Switch. The docs describe protocol revenue sources as T-bill collateral yield, protocol fees, and Fira lending fees, then route 30% to USUALx stakers and 70% to the DAO treasury. Revenue distribution docs

That is conceptually strong: Usual is trying to make USUAL a governance token with real cash-flow linkage. But it also creates a valuation trap. USUAL itself is down sharply from its all-time high: CoinGecko shows USUAL around $0.010, about $18M market cap, $2.65M 24h volume, roughly 1.79B circulating supply, and 3B max supply. Token value capture still needs proof beyond the stablecoin supply number. CoinGecko USUAL

Market Data and Liquidity

Metric	June 23, 2026 Snapshot
USD0 CoinGecko rank	#95
USD0 price	~$0.999
USD0 market cap / FDV	~$553M
USD0 24h volume	~$824K
USD0 circulating / total supply	~553.6M
DefiLlama circulating value	~$553.1M

bUSD0 price	~$0.964
bUSD0 FDV / total supply	~$508M / ~526.9M
USUAL market cap / FDV	~$18M / ~$18.6M

Onchain liquidity is thinner than the headline supply. Dexscreener shows the largest visible Ethereum bUSD0/USD0 pools around $3.7M each, with the Uniswap pool doing about $740K 24h volume and the Curve pool about $30K. The main visible USD0/USDC pool on Uniswap has about $2.0M liquidity and $44K 24h volume; the Curve USD0/USDC pool has about $616K liquidity and $9.9K 24h volume. Arbitrum USD0/USDC liquidity is much smaller, around $96K with negligible visible volume. Dexscreener USD0/USDC Dexscreener Arbitrum USD0/USDC

GoPlus shows the Ethereum USD0 token as open-source and proxy-based, with no buy or sell tax and about 123,813 holders. It also shows the bUSD0 token as open-source and proxy-based, with about 3,053 holders. Upgradeability is normal for an evolving stablecoin protocol, but it belongs in the risk model. GoPlus USD0 GoPlus bUSD0

The market-structure conclusion is simple: USD0 has a credible $550M supply base, but visible secondary liquidity is not deep enough to treat it as core cash. The product is still more of an RWA DeFi strategy ecosystem than a universally liquid settlement dollar.

Competitive Landscape

Asset	Category	Edge	USD0 Comparison
USDC	Regulated fiat-backed stablecoin	Deep liquidity, institutional trust, simple redemption	USD0 has more onchain reserve transparency but much less distribution
USDT	Global liquidity dollar	CEX, emerging-market, and settlement network effects	USD0 cannot match liquidity or acceptance
PYUSD	Regulated PayFi stablecoin	PayPal/Venmo distribution and payment rails	USD0 has a DeFi/RWA issuer-economics angle
GHO	Aave-native DeFi stablecoin	Aave collateral and borrow demand	USD0 is RWA-backed, not Aave credit-backed
USDf / USDe	Synthetic dollars	Yield and capital efficiency	USD0 has less strategy/CEX risk but has bond/liquidity complexity
USYC / USTB / BUIDL	Tokenized Treasury products	Direct fund/collateral exposure	USD0 abstracts the RWA into a stablecoin and governance ecosystem

USD0's strongest wedge is not payments. It is the conversion of tokenized Treasury yield into DeFi-native stablecoin products plus governance economics.

Scenario Analysis

Scenario	Probability	What Happens	USD0 Implication
Bull	25%	USD0 supply grows above $1B, sUSD0 becomes sticky, bUSD0 discount narrows predictably, and USUALx revenue distributions become visible and durable	Usual becomes a top-tier RWA-stablecoin issuer model
Base	50%	USD0 remains useful but niche, most supply stays tied to bUSD0 and strategy users, liquidity grows slowly	Selective RWA stablecoin watchlist
Bear	25%	bUSD0 discount widens, USUAL emissions lose value, liquidity remains thin, or redemption/collateral-provider friction appears	Avoid as reserve collateral; treat only as high-risk structured stablecoin exposure

The current base case is constructive but cautious. The protocol has a differentiated design, but the market is already pricing bUSD0 below par and USUAL far below prior highs.

Risks and Mitigants

Risk	Severity	Why It Matters	Monitor
bUSD0 discount risk	High	Most USD0 appears economically tied to bUSD0, which trades below par before 2028 maturity	bUSD0/USD0 price, rt-bUSD0 liquidity, floor changes
Secondary liquidity risk	High	Visible USD0/USDC liquidity is small versus supply	Uniswap/Curve liquidity, volume, slippage
Redemption-path complexity	High	Permissioned RWA rails and CP matching make redemption more complex than USDC	Direct/indirect redemption times, CP incentives
USUAL emissions risk	High	bUSD0 yield depends partly on USUAL coupon value	USUAL price, emissions, revenue switch payouts
Collateral-provider risk	Medium-High	Primary collateral relies heavily on institutional tokenizers like Hashnote USYC	Collateral composition, custody, audits, provider changes
Governance risk	Medium-High	DAO can change floor price, emissions, collateral, and parameters	UIP votes, emergency actions, risk parameter changes
Smart-contract/admin risk	Medium	USD0 and bUSD0 are proxy-based in GoPlus output	Upgrade history, audits, multisig/governance controls
Documentation drift	Medium	Risk-policy docs include update caveats in some markdown pages	Prefer live dashboards and governance records over static docs

Verdict

Usual USD (USD0) is a selective RWA-stablecoin watchlist, not core reserve collateral.

The bull case is compelling: USD0 uses tokenized Treasury collateral, onchain reserve logic, a multi-collateral roadmap, bUSD0/sUSD0 yield products, and a governance token that is explicitly designed to capture protocol economics. That is a more imaginative stablecoin issuer model than simply wrapping T-bills and keeping the spread.

The caution is equally important. Most observed USD0 appears locked into bUSD0, bUSD0 trades at a discount, visible USD0/USDC liquidity is shallow relative to supply, and USUAL has suffered heavy price compression. The protocol can still be useful and innovative, but the risk is not just reserve quality. It is product-structure risk: lock-ups, floor-price governance, rt-bUSD0 market depth, emissions, and redemption-path complexity.

My current conclusion: watchlist, not cash. USD0 becomes more compelling if the protocol proves that its RWA backing can support deep liquid stablecoin usage while bUSD0 and USUALx become sustainable cash-flow products instead of incentive-driven wrappers.
