GENIUS法は、米国のステーブルコインに関する国家的イノベーションの指針と確立を目的とした法律であり、2025年7月18日にPublic Law No. 119-27として成立しました。これは、米国連邦政府が支払いステーブルコインに特化した法的規制枠組みを初めて制定したものです。That was the law. Now comes the part that actually determines what the law means in practice. 2026年3月2日、連邦準備制度理事会（OCC）は連邦官報に提案規則通知（Notice of Proposed Rulemaking）を掲載し、GENIUS法の広範な立法言語を具体的かつ執行可能な運用要件に翻訳した包括的な実施フレームワークの草案を公開しました。これは、米国内で支払いステーブルコインを発行したいすべての事業体に対して適用されるものです。This is not a policy paper or a guidance document. This is the actual regulatory blueprint and the industry is reading every line of it with enormous intensity, because the decisions embedded in these proposed rules will determine who can participate in the stablecoin market, under what conditions, and at what cost.

The draft rules establish exactly three categories of entities legally permitted to issue payment stablecoins in the United States. The first category is subsidiaries of insured depository institutions meaning traditional banks that want to issue stablecoins must do so through a separately established subsidiary, not directly from the bank itself, and that subsidiary must receive explicit approval from its primary federal banking regulator. The second category is federal qualified payment stablecoin issuers, which are non-bank entities that receive a specific OCC license to issue payment stablecoins and are regulated exclusively by the Comptroller of the Currency. The third category is state qualified payment stablecoin issuers, regulated by individual state banking regulators under frameworks that must meet minimum federal standards. The GENIUS Act makes it explicitly unlawful for any person or entity to issue payment stablecoins in the United States outside of these three approved structures meaning existing major stablecoin issuers like Tether and Circle must fit themselves into one of these three boxes or exit the US market entirely. The GENIUS Act is clear that it applies to any stablecoin used by US persons, regardless of where the issuer is headquartered, which puts Tether's compliance path directly in the regulatory spotlight given its dominant global market position.
準備金要件：フレームワークの核心
The reserve rules are the structural heart of the entire proposed framework and the section drawing the most scrutiny from issuers, lawyers, and financial analysts. Under the draft rules, every permitted payment stablecoin issuer must maintain reserves equal to 100 percent of the outstanding issuance value of payment stablecoins in circulation with outstanding issuance value defined specifically as stablecoins for which the issuer has an active redemption obligation, excluding stablecoins minted but not yet sold and stablecoins repurchased but not yet burned. The OCC's proposed framework requires that these reserve assets meet specific liquidity and diversification standards, meaning issuers cannot simply hold any asset they choose as backing the reserve the portfolio must be composed of assets that can be liquidated quickly and reliably to meet redemption demands without market disruption. The draft rules also implement specific requirements for custodial services, requiring that entities providing custody of payment stablecoins, reserve assets, stablecoins held as collateral, and private keys be subject to OCC-supervised safekeeping standards a significant expansion of regulated custodial infrastructure requirements across the industry.
資本要件：意図的に柔軟なアプローチ
One of the most consequential and debated aspects of the proposed rules is the OCC's decision not to establish standardized minimum capital requirements for permitted payment stablecoin issuers. The draft explicitly states that due to the novelty of payment stablecoins and the variety of business models currently being discussed across the industry, the OCC believes that setting capital requirements based on individual evaluations of each prospective issuer is more appropriate than applying a one-size-fits-all minimum. Instead, the GENIUS Act requires that capital requirements be tailored to the specific business model and risk profile of each issuer, that they not exceed what is necessary to ensure ongoing operations, and that they may include capital buffers where the OCC determines this is necessary. The OCC's focus for capital purposes is primarily on operational risk the risk of systems failures, fraud, processing errors, and management breakdowns on the basis that other traditional banking risks like credit risk, market risk, and interest rate risk are either minimal for well-structured stablecoin issuers or are adequately addressed through the reserve asset framework. This flexible approach has been cautiously welcomed by the crypto industry as pragmatic, though some traditional banking sector voices have questioned whether individualized assessments are rigorous enough at scale.
許可された活動範囲は意図的に狭く
The proposed rules are deliberately restrictive about what permitted payment stablecoin issuers are allowed to do beyond their core function. Under the draft framework, issuers are limited to issuing and redeeming payment stablecoins, managing their reserve portfolios, providing related custodial services, and any other activities that directly support those core functions subject to OCC approval. This means a licensed payment stablecoin issuer cannot simply expand into lending, trading, or other financial services without separate regulatory authorization. All stablecoin activities must remain within the statutory framework of the GENIUS Act and stay subject to ongoing OCC supervision and compliance monitoring. The OCC retains exclusive visitorial authority over federally chartered issuers, and the draft rules explicitly preempt certain state laws with respect to federal qualified payment stablecoin issuers a direct federal override of the patchwork of state-level crypto regulations that had previously created significant compliance complexity for nationally operating stablecoin businesses.
連邦準備制度の立場と今後の展望
Federal Reserve Governor Barr delivered remarks on March 31, 2026, acknowledging that the GENIUS Act made important progress but emphasizing that the outcome depends heavily on how regulators implement it. Barr identified the unresolved pressure points as: the appropriate scope of permissible reserve assets, the risk of regulatory arbitrage between federal and state-chartered issuers, the scope of activities permitted beyond core issuance, anti-money laundering control requirements, and consumer protection standards. The GENIUS Act becomes fully effective on the earlier of January 18, 2027 which is 18 months after enactment or 120 days after the primary federal regulators issue final regulations. That means if the OCC finalizes its implementation rules by approximately September 2026, the law could take effect as early as January 2027, compressing the compliance timeline significantly for every existing stablecoin issuer operating in or serving US persons. The comment period on the draft rules is now open, and every major stablecoin issuer, traditional bank, crypto exchange, and DeFi protocol with US exposure is expected to file detailed responses. The #GENIUSImplementationRulesDraftReleased moment is not the end of the regulatory process it is the moment the real work begins. The rules that come out of this comment period will define the stablecoin market structure for the next decade. #CreaterLeaderBoard
