Choosing a settlement stablecoin is often framed as a liquidity decision, but for finance leaders that framing is incomplete. The stablecoin that’s deepest on a centralized exchange order book is rarely the same stablecoin that minimizes audit findings, fits a U.S. money transmitter license footprint, satisfies a bank partner’s onboarding diligence, or aligns cleanly with the GENIUS Act federal framework. The GENIUS Act becomes effective on the earlier of January 18, 2027 or 120 days after final implementing regulations are issued, so the precise compliance date depends on regulatory rulemaking pace. This guide compares the four most relevant U.S.-context settlement stablecoins for fintech, payments, and digital asset operators in 2026, namely USDC, USDT, PYUSD, and RLUSD, from a CFO and Controller perspective. The framework covers reserve composition, attestation cadence and provider, regulatory posture, GENIUS Act fit, chain coverage, redemption mechanics, yield treatment, and counterparty controls.

Executive Summary

• According to Ridgeway Financial Services, the right settlement stablecoin for any given operator depends less on market dominance and more on how the issuer’s regulatory posture, attestation cadence, and reserve composition align with the operator’s audit, examination, and bank-partner expectations.
• USDC, issued by Circle (NYSE: CRCL), is, in our view, a clean fit for U.S.-regulated fintech and institutional treasury use, with monthly Deloitte attestations, MiCA EMT authorization in the EU, OCC conditional approval for a national trust bank, and reserves anchored in a BlackRock-managed government money market fund custodied at BNY Mellon.
• USDT, issued by Tether International (El Salvador-domiciled), retains the largest market cap and deepest global trading liquidity but operates outside the GENIUS Act framework, publishes quarterly attestations rather than full audits, and includes precious metals, bitcoin, and secured loans in its reserve composition.
• PYUSD, issued by Paxos Trust Company under NYDFS supervision and branded by PayPal, sits in a clean middle position with monthly KPMG attestations, reserves in U.S. dollar bank deposits, U.S. Treasuries, and U.S. Treasury reverse repurchase agreements, and consumer-payment integration through PayPal and Venmo, but with a smaller market cap than the top two.
• RLUSD, issued by Standard Custody and Trust Company (a Ripple subsidiary) under NYDFS supervision, is the newest of the four (December 2024 launch), uses BNY Mellon for reserve custody, attests monthly with Deloitte, and is positioned for cross-border institutional payments rather than retail trading.
• The GENIUS Act, signed July 18, 2025, becomes effective on the earlier of January 18, 2027 or 120 days after final implementing regulations are issued. The statute prohibits paying interest to stablecoin holders, requires 1:1 reserve backing in cash, Treasury bills, certain repurchase agreements, and insured bank deposits, and limits issuance to bank subsidiaries, OCC-supervised nonbanks, or state-chartered entities under certified state regimes. USDC, PYUSD, and RLUSD are positioned for compliance; USDT plans a separate U.S.-regulated brand (USAT) for that purpose.
• For most U.S.-regulated fintech operators, in our view, the practical answer is a multi-stablecoin treasury policy with USDC as the primary, PYUSD or RLUSD as institutional alternatives depending on the use case, and USDT held only where global trading liquidity or emerging-market settlement demands it, with explicit concentration limits for each.

How CFOs should evaluate settlement stablecoins

Before comparing specific tokens, it helps to fix the evaluation criteria. The criteria below are the ones that matter for finance leaders, and they’re frequently different from the criteria that matter for engineering or product teams.

Reserve composition and quality

What’s actually backing the token. Cash held in regulated banking relationships (with concentration weighted toward systemically important institutions) plus short-duration Treasury bills sits at the top of the quality stack and is the only composition that maps cleanly to the GENIUS Act definition of permitted reserve assets. Repurchase agreements collateralized by Treasuries are also permitted under the federal framework. Reserves that include corporate bonds, secured loans, gold, bitcoin, or other non-permitted assets fall outside the GENIUS Act framework and create disclosure complications under U.S. GAAP for any holder treating the token as a cash equivalent.

Attestation cadence and provider

How often the issuer’s reserves are independently confirmed, and by whom. Monthly attestations from a top-tier accounting firm under AICPA AT-C standards are widely regarded as the current market norm for U.S.-regulated stablecoins. Quarterly attestations provide less frequent assurance. Attestations performed under non-AICPA standards (such as ISAE 3000R for non-U.S. issuers) are technically valid under their own professional frameworks but carry different weight in U.S. audit and examination contexts. The attesting firm’s brand also matters: a Big Four firm, a top-five non-Big Four firm, or a smaller regional firm carry different weight in different settings.

Issuer regulatory status

What the issuer is, where it’s domiciled, and who supervises it. NYDFS-chartered limited purpose trust companies are widely regarded as a high-rigor U.S. supervision tier for stablecoin issuance. OCC-supervised national trust banks (the structure Circle and Ripple have both pursued) provide federal-level oversight. State-chartered MTL holders sit in a different regulatory category focused on money transmission rather than trust supervision. Foreign-domiciled issuers operate outside the U.S. supervisory framework entirely and rely on commercial relationships with U.S. counterparties to access U.S. markets.

GENIUS Act compliance posture

Whether the issuer is structured to operate as a permitted payment stablecoin issuer when the federal framework takes effect. The GENIUS Act becomes effective on the earlier of January 18, 2027 or 120 days after final implementing regulations are issued. Under the statute, only bank subsidiaries, OCC-supervised nonbank entities, or state-chartered entities under regimes the federal government has certified as substantially similar to the federal framework can issue payment stablecoins for the U.S. market. The compliance work is non-trivial and most issuers have already begun structuring for it.

Chain coverage and redemption mechanics

Where the token is natively issued versus where it’s bridged, and how redemption to fiat actually works. Native issuance means the issuer’s contract is the canonical issuer on that chain, with mint and burn flowing directly through the issuer’s mint platform. Bridged issuance means the token on that chain is a wrapped representation locked behind a third-party bridge, with no direct redemption path to the issuer. Treasury teams should hold native tokens wherever possible and avoid bridged variants for material balances.

Yield treatment under the GENIUS Act

Whether the issuer pays interest or yield-equivalent compensation to holders, directly or indirectly. The GENIUS Act explicitly prohibits permitted payment stablecoin issuers from paying interest to holders, and recent commentary suggests the prohibition extends to revenue-share arrangements with custodial platforms that effectively pass yield to holders. This is an active area of regulatory clarification and one that can change the economics of holding a particular token materially over the next twelve months.

Counterparty controls and freeze functionality

Whether the issuer can freeze tokens at specific addresses on regulator instruction or in response to sanctions hits. All four major U.S.-context stablecoins discussed here include freeze and blacklist functionality in their token contracts. Issuer freeze capability is a useful enabler for sanctions response and regulator-driven blocking, but it does not replace the operator’s own BSA/AML, sanctions screening, transaction monitoring, escalation, and documentation controls. The operator remains responsible for its own program; the issuer’s freeze capability is a complement, not a substitute. Conversely, holding a stablecoin without any issuer freeze functionality creates standalone sanctions exposure for the operator beyond what the operator’s own controls can practically address.

Liquidity, depth, and counterparty diversity

Where the token trades, in what depth, and who the counterparties are. USDT has the deepest centralized exchange liquidity globally. USDC has the deepest regulated U.S. and EU liquidity. PYUSD has the strongest consumer payment integration. RLUSD has the strongest cross-border institutional payment flow integration. For settlement use, the relevant question is whether liquidity is deep enough at the operator’s actual settlement venues, not whether liquidity is deep on every venue globally.

Summary comparison of leading settlement stablecoins

The four tokens compared here each occupy a distinct position in the settlement stablecoin landscape. USDC is the institutional default for U.S.-regulated activity. USDT is the global trading default and the largest by market cap. PYUSD is the consumer-payment stablecoin with the strongest brand recognition outside crypto. RLUSD is the institutional cross-border payments stablecoin built specifically for enterprise settlement use cases.

The market cap differences are large. USDT is the largest stablecoin globally by a wide margin, followed by USDC. RLUSD and PYUSD are substantially smaller. Market cap correlates with trading liquidity but does not correlate cleanly with regulatory posture, attestation quality, or institutional fit. A finance leader making a settlement choice for a U.S.-regulated fintech may reasonably choose the smaller of the four if it fits the operator’s regulatory profile better.

Stablecoin-by-stablecoin deep dive

USDC (Circle)

USDC is issued by Circle Internet Group, a public company listed on the NYSE under ticker CRCL since June 2025. USDC is consistently the second-largest stablecoin globally by market cap, behind USDT. The combination of public-company status, regulatory licensing, and reserve transparency puts USDC among the cleanest U.S. compliance postures of the four tokens compared here, in our view.

Reserves. USDC reserves consist primarily of short-duration U.S. Treasuries and cash-equivalent assets held through the BlackRock-managed Circle Reserve Fund (ticker USDXX), an SEC-registered 2a-7 government money market fund custodied at BNY Mellon. Approximately 80% of reserves sit in the Reserve Fund and the remainder sits as cash held through regulated banking relationships, with Circle stating that the cash portion is held overwhelmingly in global systemically important banks. Circle publishes the Reserve Fund’s CUSIP-level Treasury holdings daily on the BlackRock fund page, which is unusual transparency relative to peers.

Attestation. Circle publishes monthly attestation reports issued by Deloitte and Touche under AICPA AT-C standards. Circle has delivered a long-running stream of consecutive monthly attestations since USDC’s launch. The attestation cadence and the attesting firm both sit at the top of the market norm.

Regulatory status. Circle holds money transmitter licenses across most U.S. states (plus the District of Columbia and Puerto Rico), an NYDFS BitLicense, and a French ACPR Electronic Money Institution license under MiCA, making USDC the largest fully-authorized stablecoin in the EU after Tether opted not to pursue MiCA authorization. Circle has also publicly announced OCC conditional approval to establish First National Digital Currency Bank, a national trust bank that would oversee USDC reserve management under federal supervision. The current list of Circle’s regulatory authorizations is published on Circle’s website.

Chain coverage. USDC is natively issued on a wide and growing list of chains, with native deployments across the major EVM L1s and L2s, Solana, Stellar, and others. Circle continues to add native chains regularly, so any specific count goes stale quickly; the most current native-chain list is published on Circle’s website. Circle’s CCTP V2 burn-and-mint protocol connects a substantial subset of these chains, allowing direct cross-chain movement without bridge custody risk. Treasury teams should verify the most current native-chain list directly from Circle before integration.

GENIUS Act fit. USDC is positioned for direct compliance once the federal framework takes effect. The OCC trust bank charter, monthly Big Four attestation, and reserve composition align with the statute’s requirements. Circle’s distribution arrangement with Coinbase, under which Circle pays Coinbase a portion of reserve income proportional to USDC held in Coinbase custodial wallets, is the subject of active legal commentary. Some observers argue the structure may conflict with the GENIUS Act prohibition on paying interest to holders; this is a legal interpretation question rather than a settled regulatory determination. The arrangement itself is disclosed in Circle’s S-1 and ongoing public filings. The interpretation is unresolved at publication and worth monitoring with counsel for any operator using Coinbase custodial USDC at material scale.

CFO takeaways. In our view, USDC is a strong default choice as the operating-account stablecoin for U.S.-regulated institutional treasury programs and audit-sensitive use cases. The institutional integrations with Visa, Mastercard, Stripe, and BNY Mellon support that view. The primary watch items are reserve concentration risk (the March 2023 Silicon Valley Bank brief depeg event remains an instructive case study) and the unresolved GENIUS Act yield-distribution question with Coinbase, which depends on regulatory interpretation that has not been settled.

USDT (Tether)

USDT is issued by Tether International, S.A. de C.V., domiciled in El Salvador. USDT is the largest stablecoin globally by market cap and the dominant token for emerging-market dollar access and centralized exchange trading.

Reserves. USDT reserves are mixed in composition. Recent BDO attestations describe a reserve composition heavily weighted toward U.S. Treasury exposure (direct holdings, repurchase agreements, and money market funds) along with allocations to physical gold, bitcoin held as part of the excess buffer, and secured loans. Total reserves are dominated by Treasury exposure but the inclusion of gold, bitcoin, and secured loans places USDT outside the GENIUS Act definition of permitted reserve assets for U.S.-issued payment stablecoins. The current quarterly composition is published on Tether’s transparency page.

Attestation. Tether publishes quarterly reserve assurance reports prepared by BDO Italia under IAASB standards, not under AICPA AT-C standards. These are point-in-time reserve assurance reports rather than full GAAS financial statement audits. Tether announced in March 2026 that it had engaged a Big Four firm to conduct its first full independent financial statement audit. As of publication, the audit is underway and no public completion date has been confirmed.

Regulatory status. Tether is foreign-domiciled, does not hold MiCA EMT authorization, does not hold an NYDFS license, and operates outside the U.S. federal stablecoin supervisory framework. The 2021 CFTC settlement (a $41 million penalty for misrepresentations about reserves during 2016 to 2018) is settled but remains the most-cited regulatory event in USDT’s history.

Chain coverage. USDT is natively issued on numerous chains, with the largest concentration on Tron (approximately $86 billion of supply, driven by emerging-market remittance demand) and Ethereum. Coverage extends to Solana, Avalanche, Polygon, Arbitrum, and others.

GENIUS Act fit. USDT in its current form does not fit the GENIUS Act framework. The reserve composition includes non-permitted assets (gold, bitcoin, secured loans), the issuer is foreign-domiciled, and the attestation cadence and provider standards do not align with the federal expectation. Tether announced in September 2025 that it would launch USAT, a separately structured U.S.-regulated stablecoin designed for GENIUS Act compliance. Per Tether’s announcement, USAT is planned to be issued by Anchorage Digital (a federally chartered bank that Tether has named as the GENIUS Act-compliant issuer) with Cantor Fitzgerald serving as reserve custodian, and Bo Hines was named CEO of Tether USAT. The launch and the structuring of USDT in U.S. markets after the federal framework takes effect are separate workstreams.

CFO takeaways. USDT remains the dominant token for global trading and emerging-market settlement, and excluding it from a treasury policy entirely is impractical for many operators. For U.S.-regulated fintech and audit-sensitive use cases, USDT generally belongs as a tactical position with explicit concentration limits, in our view, rather than as the primary settlement stablecoin. Operators holding material USDT balances should expect bank partner and auditor questions about reserve composition, the offshore issuer structure, and the absence of a full GAAS audit on the existing USDT issuer. The practical posture is to use USDT where global liquidity demands it, to size exposure with the existing risk profile in mind, and to track Tether’s separate USAT initiative as a potentially relevant U.S.-regulated alternative once it is operational.

PYUSD (PayPal / Paxos)

PYUSD is issued by Paxos Trust Company, LLC, an NYDFS-supervised limited purpose trust company, and branded by PayPal. PYUSD has grown materially over the past year and ranks among the larger fiat-backed stablecoins by market cap, though it is materially smaller than USDC and USDT. PYUSD’s defining feature is its consumer payment integration through PayPal and Venmo, both of which natively support PYUSD purchases, transfers, and cross-currency conversion.

Reserves. PYUSD reserves are held 100% in U.S. dollar bank deposits, U.S. Treasuries, and U.S. Treasury reverse repurchase agreements, with assets segregated from Paxos corporate assets under New York trust law. The reserve composition fits cleanly within the GENIUS Act definition of permitted reserve assets.

Attestation. Paxos publishes monthly reserve reports and monthly third-party attestations. Per Paxos’ transparency disclosures, attestation reports issued on or after February 28, 2025 are prepared by KPMG LLP, an independent third-party accounting firm, in accordance with attestation standards established by the AICPA. Earlier attestations were issued by WithumSmith and Brown, PC, also under AICPA standards.

Regulatory status. Paxos operates as an NYDFS-regulated limited purpose trust company, the same charter type that backs RLUSD, GUSD, and several other regulated stablecoins. The NYDFS trust charter is a high-rigor U.S. state supervisory framework for stablecoin issuance.

Chain coverage. PYUSD is natively issued on Ethereum, Solana, Arbitrum, and Stellar. Additional permissionless variants (such as PYUSD0) have been deployed to other networks. PayPal continues to expand chain coverage and the most current list is published in PayPal’s cryptocurrency terms.

GENIUS Act fit. PYUSD’s NYDFS charter, monthly Big Four attestation, and permitted reserve composition position it for direct compliance once the federal framework takes effect. PayPal currently advertises a PYUSD Rewards Program offering up to 4% annual rewards on PYUSD held in eligible PayPal accounts. The official terms describe the rewards rate as variable and subject to change at any time. Like the Circle-Coinbase distribution arrangement, the PYUSD Rewards structure has drawn legal commentary on whether it constitutes interest paid to a holder under the GENIUS Act prohibition. Whether either arrangement actually conflicts with the statute is a legal interpretation question that has not been settled by regulators or courts. The structures themselves are publicly disclosed; how they will be treated post-implementation is the open question.

CFO takeaways. In our view, PYUSD is a strong institutional choice for any operator with PayPal or Venmo distribution as a material part of the customer journey. The Paxos charter and KPMG attestation give the token credible audit and compliance credentials. The smaller market cap and thinner exchange liquidity outside the PayPal ecosystem are practical limits for treasury and trading use cases. The rewards arrangement is the principal watch item from a legal-interpretation standpoint and warrants discussion with counsel before scaling material balances.

RLUSD (Ripple / Standard Custody)

RLUSD is issued by Standard Custody and Trust Company, a Ripple subsidiary chartered by NYDFS as a limited purpose trust company. RLUSD launched in December 2024 and has been growing in market cap since launch, with circulating supply backed by reserve fund value as disclosed in Standard Custody’s monthly transparency reports. The product is built specifically for institutional cross-border payments and settlement rather than retail trading or consumer payments.

Reserves. RLUSD reserves consist of U.S. dollar deposits, short-dated U.S. Treasuries, and cash equivalents held in segregated accounts at BNY Mellon. The composition fits within the GENIUS Act definition of permitted reserve assets and aligns with NYDFS guidance on U.S. dollar-backed stablecoins.

Attestation. Standard Custody publishes monthly reserve attestations issued by Deloitte under AICPA AT-C standards. Attestations cover both circulating supply and reserve composition. The attestation cadence and provider both sit at the top of the market norm and align with the corresponding USDC posture.

Regulatory status. Standard Custody operates under an NYDFS limited purpose trust charter. In December 2025, Ripple received OCC conditional approval to establish a national trust bank, which would provide federal-level supervision in addition to the NYDFS charter. RLUSD has also been recognized as an Accepted Fiat-Referenced Token by the Financial Services Regulatory Authority (FSRA) of Abu Dhabi Global Market (ADGM), enabling its use by FSRA-licensed firms within ADGM for regulated activities. Separately, Ripple has secured a license from the Dubai Financial Services Authority (DFSA) for activities in the Dubai International Financial Centre, and Ripple holds an Electronic Money Institution license in the UK.

Chain coverage. RLUSD is natively issued on the XRP Ledger and Ethereum. Multichain expansion through Wormhole NTT is planned for additional chains in 2026 pending NYDFS approval. Ripple controls the smart contracts on each destination chain to maintain compliance and native mint and burn capability.

GENIUS Act fit. RLUSD’s NYDFS charter, OCC conditional trust bank approval, monthly Big Four attestation, and permitted reserve composition position it for direct compliance once the federal framework takes effect. RLUSD does not pay yield to holders and does not appear to have any custodial distribution arrangement raising the same questions Circle and PayPal are facing.

CFO takeaways. RLUSD is positioned among the four tokens as the institutional cross-border payments stablecoin. Its integration with Ripple Payments and a publicly announced settlement pilot with Mastercard, WebBank, and Gemini for Gemini Credit Card flows on the XRP Ledger are the practical use cases the product is built for. Ripple has also publicly described RLUSD as eligible for use as collateral in institutional contexts and has announced regional banking partnerships in the Middle East and Africa; operators evaluating these specific institutional integrations should review Ripple’s primary disclosures rather than relying on summary claims. The smaller market cap and the relative novelty of the product are the practical watch items.

Yield, tax, and accounting considerations

The accounting treatment of stablecoin holdings has evolved with FASB ASU 2023-08, which moved certain crypto asset accounting to fair value measurement for fiscal years beginning after December 15, 2024. The standard’s scope is narrow: it applies only to crypto assets meeting all of the standard’s scope criteria, including that the asset does not provide the holder with enforceable rights to or claims on underlying goods, services, or other assets. Whether any specific stablecoin meets all scope criteria is a token-by-token analysis that depends on the issuer’s terms of service, the redemption mechanics, and the legal characterization of the holder’s rights. Some stablecoins may fall outside the standard’s scope and be measured under different guidance. Operators should obtain a technical accounting memo addressing scope before applying ASU 2023-08 measurement to any particular token.

The functional currency question is a separate analysis. ASC 830 generally treats cryptocurrencies as something other than cash or foreign currency, so directly designating a stablecoin itself as a functional currency under ASC 830 is not a typical conclusion. For an operator whose business activity is predominantly stablecoin-denominated, the more common analysis supports the U.S. dollar as the functional currency given that dollar-backed stablecoins represent claims on dollar reserves. Either way, the conclusion materially affects how gains and losses are recognized and how the financial statements present the operating activity, and the analysis should be documented in a technical accounting memo with the audit firm involved early.

Yield treatment is the second significant consideration. The GENIUS Act prohibits permitted payment stablecoin issuers from paying interest to holders. Custodial distribution arrangements and rewards programs that effectively pass yield to holders, including the disclosed Circle-Coinbase reserve income sharing arrangement and the PayPal Rewards program on PYUSD, are the subject of ongoing legal commentary on whether they fall within the statute’s prohibition. The arrangements themselves are publicly disclosed; whether they will need to be restructured under final implementing regulations is a legal interpretation question that has not been settled. Operators receiving yield-equivalent compensation tied to stablecoin holdings should expect the income treatment, related party considerations, and treatment under any restructured post-implementation arrangement to require dedicated analysis.

Tax treatment for U.S. business holders generally follows the digital asset treatment under existing IRS guidance. Dispositions of stablecoin (including stablecoin-to-stablecoin exchanges, stablecoin payments to vendors, and conversions to fiat) are generally treated as taxable events with potential gain or loss recognition, and basis tracking is required at the lot level. Transfers between wallets or accounts under the same owner’s control are generally not taxable events under current IRS guidance, although fee-related complications can arise in specific fact patterns. The administrative burden of basis tracking across high-frequency settlement use cases is significant and is one of the practical reasons sophisticated operators concentrate stablecoin activity in a small number of tokens rather than diversifying broadly. For a deeper view on the digital asset accounting and tax considerations, RFS publishes work covering technical accounting memos for crypto companies and blockchain bookkeeping and accounting.

Compliance and regulatory fit

Stablecoin selection has compliance consequences beyond the accounting treatment. For operators with U.S. money transmitter licenses or pursuing them, the stablecoin used for settlement affects permissible investment ratios, customer fund segregation analysis, and examination outcomes. State examiners increasingly ask which stablecoins are held, who the issuer is, what the reserve composition looks like, and how the operator monitors the issuer for ongoing risk. The answers are easier when the stablecoin is regulated under U.S. supervision.

For operators with BSA/AML obligations, the stablecoin’s freeze and blacklist functionality matters at the infrastructure level. All four tokens compared here include freeze functionality, which means the issuer can comply with sanctions instructions and OFAC requirements without the operator needing to maintain its own enforcement layer. Operators also need to monitor the issuer’s freeze list activity, because addresses appearing on the freeze list may indicate counterparty exposure that the operator’s own sanctions screening should also catch.

For operators with bank partner relationships, the stablecoin choice often shows up in the bank’s onboarding and ongoing diligence. Banks providing fiat on-ramps, off-ramps, and settlement infrastructure for stablecoin operators are increasingly applying differentiated risk treatment based on the issuer. In our experience working with bank-fintech relationships, USDT exposure typically draws more diligence questions than USDC exposure. RLUSD and PYUSD generally fall in a similar position to USDC for U.S. bank diligence purposes, in our view, although individual bank policies vary. Operators should expect the stablecoin choice to surface in the diligence file regardless of how the operator presents it.

For deeper coverage of the regulatory and compliance overlay specific to fintech and crypto operations, see the RFS money transmitter license guide and the compliance officer role for fintech and crypto.

Treasury operations and multi-stablecoin strategy

Most operators of any meaningful scale end up holding multiple stablecoins rather than a single one. The reasons are practical: liquidity is concentrated differently across venues, customer-facing distribution may require a specific token, and the regulatory diversification across issuers reduces single-counterparty exposure. The treasury policy should reflect this rather than fight it.

A workable framework for U.S.-regulated fintech operators in 2026, in our view, is to designate USDC as the primary settlement and operating-account stablecoin (the largest single position, with the deepest U.S. regulated liquidity), to hold PYUSD or RLUSD as institutional alternatives where the use case fits (consumer payments through PayPal and Venmo or cross-border B2B through Ripple Payments), and to size USDT exposure to the minimum required for global trading liquidity. Each stablecoin should have an explicit position limit defined as a percentage of total stablecoin holdings or as an absolute dollar amount, and the limits should be reviewed quarterly along with the rest of the treasury policy.

The depeg policy is the second significant element. Each stablecoin should have a defined monitoring threshold (a percentage deviation from the dollar peg over a defined time window), an escalation protocol that triggers at the threshold, and a defined set of actions if the deviation extends. Depeg events are rare but consequential. The March 2023 USDC depeg following the Silicon Valley Bank failure briefly traded USDC at $0.87 on some venues. An operator without a defined depeg policy at that point would have made decisions in real time under stress, which is the worst time to make them.

The independent reserve administration question, covered in more depth in the RFS post on stablecoin reserve monitoring, applies primarily to the operator’s own treasury holdings: who is independently confirming that the operator’s stablecoin balances actually exist on the chains they’re supposed to be on, that the wallets are controlled by the right parties, and that the reconciliation to the operator’s books is current. This is operator-side reserve administration, not issuer-side, but the underlying control concept is the same.

Guidance by persona

U.S.-regulated fintech and payments operators

USDC as the primary, PYUSD or RLUSD as institutional alternatives based on use case, USDT held only where global liquidity demands it. The bank partner diligence and MTL examination calendar both push toward U.S.-regulated, NYDFS-chartered, or OCC-supervised issuers.

Crypto-native operators (exchanges, brokers, custodians)

USDT for trading liquidity (the practical reality of centralized exchange order books), USDC for U.S. customer activity and regulated-venue listings, and an evaluation of RLUSD if the operator is active in cross-border settlement or institutional digital asset treasury services. The compliance calendar and the BSA/AML program design should account for the differential issuer risk across these tokens.

Cross-border B2B payment operators

RLUSD warrants serious evaluation given Ripple Payments integration and corridor support. USDC remains a practical choice given the multi-chain native footprint and CCTP V2 cross-chain mechanics. USDT exposure follows the corridor: emerging-market settlement frequently uses USDT on Tron, and that flow may be unavoidable depending on the corridor.

Consumer fintech and payments operators with PayPal exposure

PYUSD becomes the natural primary for the consumer-facing flow, with USDC as the operating-account stablecoin and limited USDT exposure for any global liquidity needs. The PayPal Rewards program creates yield treatment questions worth surfacing with auditors and regulatory counsel before scaling.

Institutional treasuries and corporate operators

USDC is, in our view, a strong institutional default given the BlackRock-managed reserve fund, BNY Mellon custody, public-company issuer transparency, and the deepest U.S. and EU regulated integration we observe. RLUSD is becoming a credible institutional alternative, particularly following Ripple’s announced regulatory wins and institutional pilots. PYUSD is a fit for treasuries with PayPal ecosystem exposure. USDT is generally not the institutional default in this segment, in our experience.

Looking for alternatives

The four tokens compared above are not the only relevant settlement stablecoins, and a complete treasury analysis often considers a few additional names.

USDS (formerly DAI, rebranded under the Sky protocol) is among the largest decentralized stablecoins. The decentralized governance, crypto-collateralized reserve mechanics, and DeFi-native distribution put USDS in a different category than the four centralized tokens compared above. For operators with active DeFi exposure or DAO-treasury use cases, USDS is worth evaluating on its own merits, with the understanding that the regulatory framework is fundamentally different.

USD1, issued through World Liberty Financial, grew rapidly in early 2026 and has reached a meaningful position among fiat-backed stablecoins. The political associations of the issuer have drawn substantial commentary. The stablecoin has achieved significant exchange listings and trading depth. Operators evaluating USD1 should pay particular attention to the issuer structure, attestation cadence, and the political risk profile.

FDUSD (First Digital USD) and USDP (Pax Dollar, also from Paxos) are smaller fiat-backed alternatives that show up in specific exchange or distribution contexts. Both publish reserve attestations and operate under regulated structures, but neither has the institutional integration breadth of the four tokens compared in detail above.

USDe (Ethena) is a synthetic dollar that maintains its peg through delta-hedging staked assets and short perpetual positions rather than through fiat reserves. USDe is a fundamentally different product from the four tokens compared above, with different risk characteristics and a different regulatory analysis. It should be evaluated as a yield-bearing synthetic dollar, not as a settlement stablecoin in the same category as USDC, USDT, PYUSD, or RLUSD.

Questions your CFO should ask before choosing

The decision to designate a primary settlement stablecoin is not a one-time technical evaluation. The questions below are the ones that surface in audit walkthroughs, MTL examinations, bank partner diligence, and board discussions about the treasury policy.

• Where is the issuer domiciled and who supervises it under U.S. law? Is the supervisor an NYDFS-chartered trust supervisor, an OCC supervisor, a state MTL regulator, or a foreign regulator?
• What does the latest reserve attestation say about composition, and does the composition fit within the GENIUS Act definition of permitted reserve assets?
• Who is the attestation provider, what standards is the firm working under, and what is the cadence?
• Has the issuer ever been the subject of a regulatory enforcement action, settlement, or unresolved investigation? If so, has it been resolved?
• Is the issuer paying interest, yield, or revenue-share to any custodial holder of the token? If so, how does the arrangement fit under the GENIUS Act prohibition on holder interest?
• What is the freeze and blacklist functionality, who can invoke it, and how does the issuer handle sanctions instructions?
• What is the redemption mechanism, who is eligible for direct redemption, and what is the redemption SLA?
• Where is the token natively issued, where is it bridged, and what is the bridge custody structure?
• What is the issuer’s posture on a full GAAS audit (not just AT-C attestation), and what is the timeline if one is in progress?
• What does the bank partner think about this issuer in the diligence file, and is the answer documented?

Services for companies evaluating settlement stablecoins

Ridgeway Financial Services supports fintech, payments, and digital asset operators evaluating and operating stablecoin-denominated treasury and settlement programs. The work covers stablecoin treasury policy design, multi-stablecoin position-limit frameworks, depeg monitoring and escalation protocols, on-chain reconciliation across deployed chains, and accounting treatment under ASU 2023-08 and ASC 830 functional currency analysis.

RFS supports stablecoin issuers separately through the independent reserve administrator role, which is a non-attest oversight engagement covering daily reserve tie-outs, custodian confirmations, exception logging, and monthly attestation prep. Issuers and operators evaluating digital asset custody platforms in parallel may find the firm’s digital asset security platforms comparison useful as background, and operators preparing for state regulatory examinations may want to review the money transmitter license guide.

RFS also provides fractional CFO services, accounting consulting, and technical accounting memo work for fintech, payments, and digital asset companies operating stablecoin-denominated programs at any scale. Engagements are CPA-led and structured to fit alongside the operator’s existing audit, attestation, and legal counsel relationships.
