Americas Reg Desk

Friday, 2026-08-07 · covering since Wednesday's edition (5–7 Aug 2026; Thursday's edition did not run)

United States

No new structural rulemaking in this window. Several routine, immediately-effective SRO filings landed: NYSE Arca amended its Options Regulatory Fee schedule (6 Aug); NYSE American revised its options fee schedule, dropping MSCI-linked index options from certain volume-tier discounts and adding a break-up credit for CUBE auction executions (7 Aug); and Nasdaq filed to strip its legacy "Daily List" and fee-bearing fundamental-data provisions out of the rulebook (Equity 7, Section 122), moving that data's distribution terms elsewhere. None change execution mechanics. NYSE Arca filing · NYSE American filing · Nasdaq filing
