RWA vs Stablecoins for Payments: A Practical Comparison

Why this comparison matters in 2026

Two ideas that sounded similar a few years ago now compete for the same job: how a treasury or fintech actually moves dollars onchain. Stablecoins were the first product that let a wallet hold something pegged to a fiat currency without a bank in the loop, and USDT along with USDC still handle the bulk of onchain payment volume. Tokenized real-world assets started with a different promise, namely turning traditional yield-bearing instruments such as U.S. Treasury bills and money-market fund shares into tokens that can sit inside a wallet and earn interest.

The two products now overlap. A business that wants to pay a contractor in dollars on a Sunday can send USDC and have it arrive in seconds. The same business can also send BUIDL, OUSG, USDY, or USYC and let the balance earn Treasury-bill yield while it sits. That sounds like a clear win for the tokenized version, but payment flows care about more than the headline yield, and the trade-offs around speed, compliance, and flexibility decide which rail actually fits.

This article walks through how each rail works in a concrete payment context, where the two diverge most sharply, and why most professional teams end up holding both rather than picking a winner.

What tokenized Treasuries actually are

A tokenized Treasury product is a token on a blockchain whose value tracks a traditional, low-risk yield instrument. The first wave, including BUIDL from BlackRock and OUSG from Ondo Finance, holds short-duration U.S. Treasury bills or repurchase agreements backed by them. A second wave, including USDY and USYC from Ondo, wraps money-market fund shares or short-duration bond portfolios. Each token represents a pro-rata claim on the underlying assets, and a token holder earns yield as the net asset value of the token drifts up over time instead of receiving discrete distributions.

That accrual structure is the key reason these tokens look attractive for treasury use. A balance of 1,000,000 BUIDL tokens today might correspond to 1,005,200 tokens a month later, with the difference reflecting earned interest. From a treasury ledger perspective, the balance simply grows, and no separate coupon bookkeeping is required. This makes the token behave like a money-market fund share that happens to live onchain, complete with onchain transferability but with a much narrower distribution footprint than a retail money-market fund.

The flip side is that redemption rarely happens at the speed crypto users expect. Most tokenized Treasury products offer primary issuance and redemption through a regulated entity during business hours, with a settlement window of one to three business days, because the underlying traditional instruments cannot simply be liquidated inside a blockchain block. Some products, including certain Ondo offerings, launched instant-redemption features in late 2024 and 2025 by holding a stablecoin reserve layer on top of the Treasury portfolio, which closes the gap but never fully closes it. The instant feature is an overlay, not the core mechanic.

How stablecoins work as payment rails

A stablecoin is a token whose issuer claims to keep a one-to-one peg to a reference currency, almost always the U.S. dollar. USDT from Tether and USDC from Circle are the dominant payment-oriented examples, with USDC especially prominent on U.S.-facing rails because Circle is a U.S.-domiciled company with a regulated New York trust company charter. When a user holds USDC, the issuer holds a reserve portfolio of cash and short-duration Treasuries, and the user holds a token whose right of redemption runs against that reserve at par.

Payment flows on stablecoins are what made the category useful in the first place. A USDC transfer on a layer-2 network can confirm in seconds, costs fractions of a cent, and reaches any address on the network without prior approval. That is why stablecoins became the de facto payment rail for crypto-native businesses, freelance work across borders, and card-issuance programs that settle in tokenized dollars.

Stablecoins do not pay yield on the underlying token. The token sits flat at one dollar, and any return comes from offchain arrangements such as lending markets, exchange programs, or treasury-managed deposits. For users who are pure payers, that is fine, since payment neutrality is the goal. For users who treat a wallet like a treasury account, the zero yield is a real opportunity cost versus a tokenized T-bill, and it is the main reason tokenized Treasuries drew serious attention at all.

Where the two rails diverge most sharply

Three dimensions decide which rail fits a given payment flow: settlement speed, compliance reach, and yield versus flexibility. Each choice involves a trade-off rather than a free upgrade.

Settlement finality. USDC and USDT clear on the network as soon as the block is confirmed, which for a layer-2 network like Base or Arbitrum means a few seconds. Tokenized Treasuries settle in the same way as a token transfer, but the right to cash out into fiat dollars typically runs through the issuer's redemption window, which is often a one-to-two business-day process tied to bank hours. If a contractor needs dollars in their account on a Friday evening, USDC wins. If the goal is to store dollars for a month and earn yield, the tokenized Treasury wins on net.

KYC and blocklist friendliness. Stablecoin issuers run compliance programs that include address screening, sanctions blocklists, and seizure procedures under court order. Circle is well known for its close cooperation with U.S. law enforcement, and Tether has expanded its own blocklist footprint in 2024 and 2025. Tokenized Treasury products sit closer to traditional securities law, so they typically require investor-level KYC at the wallet level and may restrict transfers to wallets that have completed onboarding. The result is that the tokenized Treasury is friendlier to a compliance officer who wants to know exactly who holds the asset and less friendly to a builder who wants to plug a wallet into a smart contract and walk away.

Counterparty risk in each model. A stablecoin holder takes the credit risk of the issuer's reserve portfolio and the operational risk of the issuer's redemption process. Tokenized Treasury holders face a similar issuer credit risk plus the additional risk that the underlying Treasury positions or repo agreements underperform. Both carry some risk of regulatory action against the issuer; both have a track record of honoring redemptions in stress events. Neither model removes counterparty risk entirely. The tokenized Treasury model sometimes spreads risk further by holding shares of a regulated money-market fund, while stablecoins concentrate the risk in a single issuer balance sheet.

A concrete payment-flow example

Imagine a small exchange that needs to pay a vendor invoice of $250,000. The treasury team has three realistic paths, and the trade-offs are visible in each one.

Path one: hold everything in USDC, send $250,000 USDC to the vendor wallet, and let the vendor redeem through their own banking channel. Settlement is instant, the vendor receives dollars, and the exchange's remaining USDC balance earns nothing. If the vendor's bank or wallet provider freezes the address, the exchange has to coordinate with Circle or Tether to lift the block, which adds time.

Path two: hold a mix of USDC and a tokenized Treasury such as BUIDL. The treasury team converts $250,000 of BUIDL to USDC on a secondary market venue such as Ondo's OUSG-to-USDC pool or a decentralized exchange where the token trades, then sends the USDC to the vendor. The conversion is fast but introduces a small slippage cost and a dependence on the liquidity of the trading venue. The remaining BUIDL balance keeps accruing Treasury yield.

Path three: hold only tokenized Treasuries and pay the vendor the same way, with the additional step of requesting primary redemption from the issuer for the amount the treasury wants to liquidate. The redemption window is one to two business days, which means the treasury must plan the payment in advance. If the vendor accepts the tokenized Treasury directly, settlement becomes immediate at the token level and the vendor can choose whether to redeem or hold.

None of the three paths is universally right. Path one wins on speed. Path two balances yield and flexibility, which is why most professional teams land on it. Path three wins on yield and compliance posture but only if the vendor accepts the tokenized form. The right answer depends on how predictable the payment timing is and whether the vendor can receive tokens at all.

Why the GENIUS Act changes the math

The GENIUS Act, signed into federal law in 2025, set a federal framework for payment stablecoins that includes strict reserve backing, audit requirements, redemption rights, and issuer licensing. Issuers who meet the federal standard get reduced state-by-state friction and a clearer legal status across the United States. The law was deliberately designed to favor U.S.-domiciled issuers with conservative reserve compositions and full compliance programs.

Tokenized Treasury products were not the direct target of the GENIUS Act, but their issuers sit close to the spirit of the law. A product like BUIDL that holds U.S. Treasury bills in custody, marks to market daily, and offers a clear redemption path has reserve characteristics that look similar to what the GENIUS Act demands of a payment stablecoin. Issuers of these products can borrow the language of the act when talking to compliance officers, even though the tokens themselves are technically securities rather than payment stablecoins.

For a treasury manager weighing the two rails, the practical effect is that U.S.-aligned tokenized Treasuries and the most compliant U.S. stablecoins now operate under a coherent set of expectations. Offshore stablecoins such as USDT face more friction in U.S. payment flows, while tokenized Treasuries issued by U.S.-based asset managers have a regulatory tailwind that did not exist a few years ago. The yield-versus-compliance trade-off is therefore tilted a bit toward the tokenized Treasury side, which is why more payment-oriented teams are willing to accept the slower redemption window in exchange for the cleaner posture.

The risk layer nobody puts in the slide deck

The honest list of risks looks different for each rail, and a careful treasury manager should size them before committing meaningful volume.

For stablecoins: issuer insolvency, even temporarily, can freeze redemptions. Tether survived the 2022 crypto market stress without loss to holders, but USDC briefly lost its peg in March 2023 when Silicon Valley Bank failed and a portion of Circle's reserves was inaccessible for a weekend. Blocklist risk is real: addresses can be added to issuer-level blocklists and frozen at the smart-contract level. Reserve opacity varies by issuer: Tether's reserves have been criticized for less frequent attestation than Circle's, and the difference matters for treasury users.

For tokenized Treasuries: the underlying Treasury or repo positions can underperform in a fast-rising interest-rate environment or in a funding crunch. Redemption queues can stretch if too many holders try to exit at once. KYC and accreditation rules can block certain counterparties, so a tokenized Treasury is rarely the right rail for permissionless commerce. Smart-contract risk also sits in the stack: a bug in the issuance or redemption contract can lock funds, as demonstrated by several historical DeFi incidents even when the underlying assets were perfectly safe.

Historical wipeouts to remember: the TerraUSD collapse in May 2022 wiped out roughly $40 billion in stablecoin value in a weekend and showed that algorithmic pegs without credible reserves fail under stress. The March 2023 USDC depeg briefly traded as low as $0.87 and showed that even fully reserved issuers are exposed to banking-system shocks. Various centralized yield products on tokenized Treasuries have already had bugs, freezes, or withdrawal pauses. None of these events made the product category unusable, but each one shifted the perception of which rail is appropriate for what kind of business.

How to follow this space without getting blindsided

RWA and stablecoins move fast, and the headlines around them rarely tell you whether a change in policy or issuer behavior is bullish, bearish, or noise. Tracking the underlying flow data, the reserve attestations, and the legislative calendar manually is a losing game. Zippfeed surfaces tokenized-Treasury and stablecoin headlines with sentiment scoring and an importance rating, so a treasury team can see which announcements actually move the rails and which ones are just recycled rumors.
