Monday, 2026-09-28 · covering the last 72h

United States

No material new SEC, CFTC or FINRA rulemaking, and no new Federal Reserve Board rulemaking or supervisory guidance reaching market participants, in the window. No new NYSE, Nasdaq or Cboe market-structure rule filings; the only SRO activity found was a further same-day filing in the NYSE group's series conforming associated-person exam-retake waiting periods to FINRA Rule 1210 — a registration-administration change already noted, not detailed here. The 6 December 2026 industrywide 23/5 overnight-trading launch and the SEC's tokenized-NMS-stock Innovation Exemption are unchanged since the last edition.

Canada

No material new CSA/OSC, CIRO or TMX rulemaking, and no new Bank of Canada FMI rulemaking, in the window.

Latin America

No material items from Brazil's CVM/B3/BCB, Mexico's CNBV/BIVA-BMV/Banxico, Chile's CMF/BCCh or Argentina's CNV/BCRA in the window.
