A newly published FAQ on the GENIUS Act and stablecoin regulation targets the two audiences with the most exposure to the new federal framework: broker-dealers and banks. The guidance, surfaced via Nasdaq, distills what regulated financial institutions need to know as the United States shifts from state-by-state patchwork oversight of payment stablecoins to a federal regime with defined prudential standards.

The GENIUS Act — the Guiding and Establishing National Innovation for U.S. Stablecoins Act — established the first federal regulatory framework for payment stablecoins in the United States. President Donald Trump signed it into law in July 2025, ending years of legislative negotiation over who may issue dollar-backed digital tokens and under what conditions. The statute directs federal banking regulators and, for non-bank issuers, a unified supervisory structure to license and examine stablecoin issuers.

For broker-dealers, the practical questions the FAQ addresses are operational rather than speculative. Firms that custody, distribute, or facilitate customer transactions in payment stablecoins now face a defined taxonomy: tokens that qualify as payment stablecoins under the act fall outside securities treatment in most circumstances, which reshapes how firms classify inventory, capital charges, and customer disclosures. Compliance departments must map existing digital-asset workflows against the act's definitions before enforcement expectations harden.

For banks, the calculus is different but equally concrete. The act permits qualified depository institutions to issue payment stablecoins directly, subject to capital, liquidity, and reserve requirements set by their federal regulators. It also restricts non-financial public companies from issuing stablecoins, a provision aimed at separating payment instruments from corporate balance-sheet risk. Banks weighing issuance must therefore model the cost of full reserve backing and monthly public disclosure of reserve composition against the revenue potential of tokenized deposits and settlement services.

The FAQ format matters for a reason. Regulated institutions have repeatedly asked for plain-language consolidation of the act's requirements because the statute delegates substantial implementation detail to rulemaking by the Federal Reserve, the Office of the Comptroller of the Currency, and the Federal Deposit Insurance Corporation. Interagency standards on reserve eligibility, redemption practices, and anti-money-laundering obligations for issuers remain in drafting, which means the compliance picture for both broker-dealers and banks will continue to move through the implementation window.

The business consequences cut across several lines. Custody banks and trust companies that already hold digital assets for institutional clients face clarified responsibilities for segregating payment stablecoin reserves. Broker-dealers operating alternative trading venues must determine whether specific tokens meet the act's payment stablecoin definition, since misclassification carries both supervisory and customer-litigation risk. Payment processors and correspondent banks stand to gain a codified interstate framework that replaces the uncertainty that led several institutions to pause stablecoin-linked services in prior years.

The law also carves out a role for state-level regimes during a transition period, allowing issuers supervised under qualifying state frameworks to operate while federal registration systems come online. Institutions active in both channels should track how state regulators coordinate examinations with federal agencies, because dual supervision raises reporting burdens even where substantive standards converge.

What the FAQ ultimately signals is that the industry has moved from debating whether a federal stablecoin law would pass to executing against one. Broker-dealers and banks that treat the GENIUS Act's implementation phase as a planning horizon — rather than a finished rulebook — will be best positioned when the banking agencies finalize their interagency standards and the market for compliant, fully reserved payment stablecoins takes its final shape.
