United States

Cboe Clear U.S. files amended application for temporary registration as a clearing agency. Published in the Federal Register on 24 July, the amended Section 17A filing would let Cboe Clear U.S. act as central counterparty for Cboe's planned "Binary KPI Options" — cash-settled binary options referencing corporate KPIs drawn from issuers' 10-K/10-Q/8-K filings. It's new clearing infrastructure rather than a change to existing equity trading rules, but structurally notable if the SEC grants the registration. Federal Register notice

Cboe Exchange files fees for its new complex-instruments market data feed. A rule change published in the Federal Register on 27 July (filed 15 July) establishes fees for the "Exchange Designated Complex Instruments" (EDCI) feed, a filtered subset of Cboe's existing Complex Order Book data feed covering instruments such as XSP vertical spreads, box spreads and jelly rolls. Routine market-data-fee filing, effective immediately on filing. Federal Register notice
