Architectural Cases

The burgeoning U.S. stablecoin market, which has surpassed a valuation of $260 billion by 2025, grapples with an intricate and often disjointed regulatory landscape. Although comprehensive federal legislation specifically addressing stablecoins has yet to materialize, a subset of these digital assets successfully operates within the existing mosaic of state and federal oversight. This discussion delves into the current state of stablecoin regulation in the United States, examining the key entities subject to such oversight, and highlighting the inherent complexities and ramifications for market participants.

The United States' approach to digital asset governance remains largely decentralized, with no single federal statute dictating the terms for stablecoins. Instead, issuers must navigate a labyrinth of established state and federal rules, originally conceived for traditional financial instruments. Principal regulatory bodies include state financial departments, notably the New York Department of Financial Services (NYDFS), which stands as a frontrunner in state-level oversight. Concurrently, the U.S. Treasury enforces anti-money laundering (AML) protocols, while the Securities and Exchange Commission (SEC) and the Commodity Futures Trading Commission (CFTC) weigh in on whether these assets qualify as securities or derivatives, respectively. The Office of the Comptroller of the Currency (OCC) also provides guidance for national banks engaging with stablecoin activities.

Regulatory oversight for stablecoins spans several categories. State money transmitter licenses are a common requirement for entities involved in the transfer of funds, each state imposing its own distinct conditions, including capital and bonding mandates. Banking regulations offer a more stringent form of oversight, particularly for those with trust company charters, providing enhanced consumer protection through regular examinations and rigorous operational standards. The SEC employs the Howey Test to discern if a stablecoin constitutes a security, focusing on investment contracts and expected profits, with most regulated stablecoins strategically structured to circumvent this classification. Moreover, robust AML requirements, encompassing Know Your Customer (KYC) procedures, transaction monitoring, suspicious activity reporting, and sanctions screening, are foundational for all compliant stablecoin operations.

Among the stablecoins operating under U.S. regulatory frameworks, USDC (USD Coin) stands out as the largest, boasting over $65 billion in circulation. Issued by Circle Internet Financial, USDC operates with money transmitter licenses across various states and holds a New York BitLicense, though it is neither a trust company nor a bank. Its compliance measures are stringent, including monthly attestations by accounting firms, reserves held in SEC-registered money market funds, daily reporting via BlackRock, and 100% backing by cash and U.S. Treasuries. Circle actively collaborates with regulators, advocating for federal stablecoin legislation, and positions USDC for institutional adoption through its commitment to transparency and compliance.

Another notable entity is USDP (Pax Dollar), which enjoys one of the strictest forms of state oversight as a New York trust company. Paxos Trust Company, its issuer, operates under the direct supervision of the NYDFS, maintaining a bankruptcy-remote structure. Its reserves are meticulously managed, consisting of FDIC-insured bank deposits, short-term U.S. Treasuries, and overnight reverse repurchase agreements, with monthly attestations publicly available. The benefits of a trust company charter include the segregation of customer assets from corporate funds and adherence to higher regulatory benchmarks. In contrast, the discontinuation of BUSD (Binance USD) serves as a stark reminder of the critical importance of sustained compliance. Despite being initially regulated by the NYDFS under Paxos’ trust charter, BUSD faced an SEC Wells notice in February 2023, alleging it was an unregistered security, leading to its eventual cessation of issuance.

GUSD (Gemini Dollar), launched in 2018 by Gemini Trust Company, pioneered stablecoin regulation as the first NYDFS-approved stablecoin. Operating under a New York trust company charter since 2015, GUSD maintains a regulatory standing comparable to USDP. Its transparency measures include monthly attestations, on-chain verification, and reserves held in cash, money market funds, and T-bills, with real-time supply data readily accessible. Despite its strong regulatory foundation, GUSD’s market capitalization remains relatively modest, underscoring that regulation alone does not guarantee widespread adoption. On the other hand, Tether (USDT), while commanding over $160 billion in circulation and significant global liquidity, largely operates outside U.S. regulatory scrutiny, lacking NYDFS registration and functioning through offshore entities, despite previous enforcement actions by the CFTC.

The path forward for stablecoin regulation in the U.S. appears to involve a continued push for federal legislation, with various congressional bills proposing comprehensive frameworks, clear definitions for payment stablecoins, and standardized reserve and audit criteria. The SEC’s evolving stance, as indicated in April 2025, suggests certain stablecoins may not be classified as securities if they are fully backed by dollars, make no profit promises, offer simple redemption rights, and provide adequate disclosures. Furthermore, federal banking agencies have begun to permit banks to hold stablecoin reserves, engage in payment activities, operate network nodes, and offer custody services, signaling a growing integration of stablecoins into the traditional financial system. These developments highlight a dual trajectory: increasing formalization and institutional adoption alongside persistent challenges in aligning disparate regulatory perspectives.

In choosing stablecoins, users and businesses alike must weigh the benefits of regulation against practical considerations. Regulated stablecoins offer enhanced protection through segregated funds, regular audits, legal recourse, and clear bankruptcy protocols, fostering institutional acceptance and robust banking relationships. For individual users, verifying licenses, understanding redemption processes, and comparing fees are crucial. Businesses must meticulously review compliance obligations, update AML procedures, assess tax implications, and evaluate operational requirements. Looking ahead, federal stablecoin legislation is anticipated to standardize requirements, potentially leading to a more consolidated market with clearer rules. This will inevitably lead to increased oversight and a more defined regulatory environment that aims to balance innovation with critical consumer protection.
