The GENIUS Act Tier: USDC, USAT, PYUSD, RLUSD — What 'Regulated' Actually Buys You

Three stablecoin issuers might all describe themselves as 'fully regulated' in 2026. One holds an OCC national trust charter. The second operates under an NYDFS limited-purpose trust. The third runs on a stack of state money transmitter licences with a Cayman issuance entity. Same word, very different bankruptcy treatment, very different supervisory cadence, very different redemption mechanics.

After the GENIUS Act was signed on 18 July 2025, that gap stopped being academic. The law put a federal floor under what a 'payment stablecoin' must look like — but it left issuers free to choose how they meet it. Some chase a federal charter directly. Others sit at the state level under the $10 billion cap. A few are mid-pivot.

This is Part 2 of the Stablecoins 2026 series. If you want the full state-vs-federal map first, start with the US stablecoin framework. Here we go issuer by issuer: USDC, USAT, PYUSD, RLUSD, and AUSD.

Why issuer-by-issuer matters under the GENIUS Act

Quick recap. The GENIUS Act sets one final compliance deadline of 18 January 2027, with a 120-day transition window for offshore issuers. It splits the world into tier-1 (federally chartered) and tier-2 (state-chartered, capped at $10B outstanding before they must transition up). It locks reserve composition: cash, insured deposits, T-bills under 93 days, repos under 7 days, or government money-market funds backed by the same. No commercial paper. No algorithmic backing.

But the law leaves the charter itself as the load-bearing variable. An OCC national trust charter, an NYDFS limited-purpose trust, a state money transmitter licence, and a federal crypto bank charter all yield different bankruptcy treatment, different examiner cadence, and different redemption guarantees.

The OCC published its NPRM under 12 CFR Part 15 on 25 February 2026, defining the federal payment stablecoin issuer (FPSI) regime in detail. Comment period closed late April 2026. The final rule is the next big shoe to drop, expected late Q3.

What this article does not cover: offshore USDT (different conversation), algorithmic stables (banned outright), and yield-bearing tokenised money-market shares. Those last ones are regulated as securities, which is a separate question handled in SEC vs CFTC jurisdiction.

USDC (Circle): the incumbent that IPO'd into the framework

• Issuer: Circle Internet Group, NYSE-listed since 5 June 2025 under ticker CRCL — the first stablecoin issuer to go public.
• Charter path: pursuing an OCC national trust bank charter (the proposed entity is First National Digital Currency Bank N.A.) since the application filed in June 2025. In the meantime Circle operates under the New York BitLicense, multiple state MTLs, and — for the euro region — a 2024 ACPR Electronic Money Institution licence in France that delivered MiCA compliance.
• Reserves: roughly 80% in the BlackRock-managed Circle Reserve Fund (USDXX), an SEC-registered government money-market fund. The remainder sits as cash at GSIBs led by BNY Mellon.
• Attestations: monthly by Deloitte, post the 2023 transition from Grant Thornton. It is a common misconception that USDC attests weekly — it doesn't.
• Redemption: Circle Mint accounts. Same-day 1:1 for verified institutions, T+1 for retail via partners. No fee.
• Chains in 2026: more than 22 native deployments — Ethereum, Solana, Base, Arbitrum, Polygon, Avalanche, Stellar, Sui, Aptos, NEAR, Hedera, Optimism, zkSync, Linea and others. Cross-Chain Transfer Protocol v2 (CCTP) is live and removes the bridged-USDC fragmentation that defined 2022–2023.
• Scale: roughly 64% of US-regulated stablecoin transaction volume in March 2026, the first month onshore USDC overtook offshore USDT inside US-regulated venues.

What 'regulated' buys USDC holders: a 1:1 redemption right enforceable under NYDFS supervision, a clean disclosure stack that lets you read the reserve composition every month, and the broadest chain reach in the category. Pending federal trust oversight will harden the bankruptcy-remoteness story.

USAT (Tether USA): the firewalled US sibling

• Issuer: Anchorage Digital Bank N.A., the only federally chartered crypto bank in the US (OCC national trust granted January 2021).
• Launched: 27 January 2026, structurally and legally separate from offshore USDT.
• Why it exists: the GENIUS Act prohibits offering non-compliant stablecoins to US persons after the 18 July 2026 issuance deadline. Tether Limited (BVI) cannot meet GENIUS reserve and disclosure rules — so a US-only sibling was spun up under a US bank.
• Reserves: held at Cantor Fitzgerald, with short-dated US Treasuries and cash deposits. Cantor's role mirrors its existing relationship with offshore USDT, but the wrapper here is a US bank trust structure, not a BVI entity.
• Attestations: monthly by BDO USA, with stated intent to move to a formal annual audit per GENIUS Act §4(b) by January 2027.
• Chains at launch: Ethereum and Tron, with Solana and Hedera planned for mid-2026.
• Redemption: through Anchorage Digital Bank for verified institutions only. No retail mint.

What 'regulated' buys USAT holders: a US-bankruptcy-protected wrapper around the world's largest stablecoin brand. The catch — and it is a real one — is that USAT is not fungible with offshore USDT. Bridging requires off-ramp through a centralised partner. Whether market makers tighten the USAT/USDT spread by arbitrage, or whether the two diverge as separate assets, is the open question of the next 12 months.

PYUSD (PayPal/Paxos): the consumer payments play

• Issuer: Paxos Trust Company LLC, holding an NYDFS limited-purpose trust charter since 2015 — one of the original three NY trust stablecoin issuers alongside Gemini and itBit.
• Distributor: PayPal — directly redeemable inside PayPal and Venmo apps for US users.
• Reserves: 100% cash, US Treasury bills, and reverse repos at State Street and other custodians. Monthly attestations by WithumSmith+Brown, with reserve breakdowns published at the CUSIP level.
• Chains in 2026: Ethereum, Solana, Stellar, and Arbitrum (added 2025). Stellar is the largest deployment by transaction count, driven by PayPal's remittance corridor with Xoom.
• Market cap: roughly $1.0B as of late April 2026 — modest next to USDC, but with deep retail integration through more than 430 million PayPal/Venmo accounts.
• Redemption: instant in-app for PayPal users; institutional redemption via Paxos.

What 'regulated' buys PYUSD holders: NYDFS-supervised reserves and a familiar consumer redemption path. If you already live inside PayPal, your stablecoin redemption rail and your cash balance live in the same place.

RLUSD (Ripple): the cross-border settlement bet

• Issuer: Standard Custody & Trust Company LLC, a Ripple subsidiary, under an NYDFS limited-purpose trust charter granted in December 2024. Ripple separately filed for an OCC national trust charter in July 2025; that application was still pending in April 2026.
• Launched: December 2024. Market cap reached approximately $1.6B in April 2026, up from around $700M a year earlier.
• Chains: XRP Ledger (native) and Ethereum, with bridging via Axelar to additional venues.
• Reserves: short-dated US Treasuries, repos, and cash at BNY Mellon. Monthly attestations by BPM.
• Distribution: Visa and Mastercard partnerships announced in 2025 for stablecoin settlement on their B2B rails. Tightly integrated with the Ripple Payments network.
• Redemption: institutional only, T+0 to T+1 through Ripple's enterprise platform.

What 'regulated' buys RLUSD holders: NYDFS oversight with tight integration into traditional payment networks. The XRPL-native deployment also delivers 3–5 second settlement at sub-cent fees, which is the actual product RLUSD is selling — regulatory wrapper plus a genuinely fast settlement layer for cross-border B2B.

AUSD (Agora) and the long tail of regulated entrants

• Issuer: Agora Finance, Inc. Asset management partner: State Street. Advisory partner: VanEck.
• Charter: state money transmitter licences plus a Cayman issuance entity, with an NYDFS application announced in Q1 2026.
• Distinguishing model: revenue-share with distribution partners. Yield from reserves flows back to integrating DeFi protocols and fintechs rather than being captured solely by the issuer.
• Reserves: short-dated Treasuries via a VanEck-managed account at State Street, with a daily transparency feed.
• Chains: Ethereum, Avalanche, Sui, Plume — focused on B2B and DeFi rails. Roughly $200M market cap in April 2026.

Other regulated entrants showing up in 2026: Stripe's Bridge stablecoin (USDB), Société Générale's USDCV (US-issued under the OCC perimeter), and First Digital's US-domiciled FDUSD variant announced for Q2 2026. Reading the long tail under GENIUS, the $10B state-issuer cap means most newcomers must pursue an OCC charter once they scale. Expect consolidation by late 2027.

For a cross-jurisdictional view, MiCA in year two covers the European mirror of this same dynamic.

What 'regulated' actually buys you (and what it doesn't)

What regulation does buy you under GENIUS:

• A defined redemption right under US law.
• Reserve composition disclosed at attestation cadence — monthly for every issuer in this article.
• Bankruptcy remoteness, if the issuer is a chartered trust. Reserves at a chartered trust are not general estate property; they sit segregated for stablecoin holders.

What it does not buy you:

• Smart-contract risk on the chain you hold the token. A regulated issuer cannot reverse a drainer-signed approval. The risks covered in your attack surface — phishing, malicious approvals, clipboard hijackers — apply to USDC and PYUSD just as much as to anything else.
• FDIC insurance. It does not extend to stablecoin holders. The reserves may sit in insured deposits, but you are not the depositor.
• Freedom from blacklist functions. Every major regulated stablecoin in 2026 — USDC, USAT, PYUSD, RLUSD — can be frozen at the contract level by the issuer in response to a court order or sanctions action. That is a feature of the regulatory wrapper, not a bug. Self-custody users should treat it as part of the trust assumption.

The practical takeaway is that 'which stablecoin' is now a workflow question. For broad transactional use across chains, USDC is the deepest and most portable. For PayPal-native users, PYUSD is the path of least friction. For XRPL settlement and B2B rails, RLUSD. USAT is currently institutional-only. AUSD suits DeFi integrators who want a yield share.

Watch the OCC's final FPSI rule expected late Q3 2026, and watch whether tier-1 issuers consolidate around two or three federally chartered names. Part 3 of this series picks up non-USD stablecoins and how they behave under stress — which is where the regulatory wrapper gets stress-tested for real.
