Q4 opens today with two comment deadlines worth circling, a run of industry conferences, a holiday peak that Deloitte has already sized, and a statutory date that is now fixed. My view is that fintech and banking leaders should start with the fixed dates and treat everything regulators have not finalized as input they can still change.

The fixed dates

Several Q4 dates are set and sourced. Money20/20 USA runs October 18 to 21 in Las Vegas. The Federal Open Market Committee meets October 27 to 28 and December 8 to 9, and the Fed’s calendar ties the December meeting to a Summary of Economic Projections. The Singapore FinTech Festival is November 18 to 20 at Singapore Expo.

For payments teams, the peak is earlier than the conference calendar suggests. Thanksgiving falls on November 26, so Black Friday is November 27. Deloitte’s holiday forecast, released September 10, puts U.S. e-commerce sales for November 2026 through January 2027 at $316.1 billion to $318.9 billion, a rise of 7.5% to 8.4% on a year earlier. Deloitte calls disposable personal income an important input to the forecast and projects it to grow 4.5% to 5.2% over the holiday season.

Two comment deadlines

The dates I would circle are the ones where a reader’s input is still possible. On September 24 the Federal Reserve Board asked for public comment on two proposals under the GENIUS Act. One covers reserve assets, capital and risk management for Board-supervised payment stablecoin issuers. The other sets an application process for Board-supervised banks that want to issue payment stablecoins. Both were published in the Federal Register on September 29, and comments close November 30.

On September 11, the FDIC, the Fed, the NCUA and the OCC proposed new third-party risk management guidance. The agencies describe it as principles-based and non-binding, and say it would replace existing guidance once final. Comments close November 16. The guidance is written for banks and credit unions, which makes it a vendor-management question for fintechs that sell to them.

A proposal can still be changed in response to comments. A final rule can only be followed or challenged. That makes the comment period the cheapest point to raise a problem with a definition, a capital treatment or a timeline.

The stablecoin date is now fixed

The GENIUS Act’s effective-date section says the Act takes effect on the earlier of 18 months after enactment or 120 days after the primary regulators issue any final regulations. It was signed July 18, 2025, so the 18-month limb lands on January 18, 2027. The 120-day limb could only pull that earlier if a final regulation had been issued before September 20, 2026, and the Federal Register shows no final GENIUS issuer regulation before that date. Any final regulation issued from September 20 on puts the 120-day date after January 18, so January 18, 2027 is the effective date.

The OCC has said what it intends. In an August 19 release on his remarks at the Wyoming Blockchain Symposium, the OCC said Comptroller Jonathan Gould expects to have a final GENIUS Act rule out by November. That is a stated intention, not a published rule. As of today I have found no final rule from any agency on the issuer framework. The one final-form text I found is a Treasury interim final rule published September 30, issued for the Stablecoin Certification Review Committee, that sets forms and procedures for state certifications. If final text from the OCC does land in November, a bank that waited for it would have roughly two months before the statutory date.

That ordering is why I think the Fed’s November 30 deadline matters to more than Board-supervised issuers. Reserve composition, capital treatment and application contents are questions I expect every bank considering a stablecoin subsidiary to face, whichever agency supervises it, and the Fed’s proposals are the newest agency text on those questions. Our earlier opinion pieces on the Fed’s stablecoin rule and AML gaps and on bank AML systems and stablecoins cover the compliance side.

Banks also have a separate item. On September 30 the Fed finalized its stress test changes, updating the models for the 2027 test and starting stress capital buffer averaging in 2028. We take up what that means for scenario severity in an opinion piece published today.

What I would do this quarter

  1. Assign an owner to November 16 and November 30 today, and decide by early November whether the company files a comment letter on each.
  2. List every third-party service your firm depends on or provides, and read it against the September 11 guidance before November 16.
  3. If you are weighing a stablecoin program, write down your reserve mix, capital assumptions and application timeline now, and test them against the Fed’s two proposals before November 30.
  4. Use Money20/20 on October 18 to 21 to ask counterparties for their stablecoin and vendor-risk timelines, and ask each one what they plan to say to regulators.
  5. Fix your holiday payments change freeze and capacity plan before November 26.

Put the November 16 and November 30 deadlines in the shared calendar this afternoon.
