HKEX failover test and SEC Mizuho deadline lead a thin week of fixed dates
The diary ahead is short on firm dates and long on proposals whose clocks have not started. Hong Kong has pinned a weekend failover rehearsal; the SEC has one firm comment deadline on a niche swap-dealer request. The heavier US items, FDIC part 370, an ISE strike filing and a DOJ firearms rule, all count from a Federal Register date none of the briefings states.
- HKEX runs its CCASS, FINI and RAP failover rehearsal on Saturday 21 November 2026, with registration closing 13 November and RAP also suspended on 7-8 November.
- The SEC is accepting comment through 2 December 2026 on Mizuho Capital Markets' request to raise Rule 18a-10's threshold from $50 billion to $100 billion.
- The FDIC part 370 rescission (60 days), Nasdaq ISE's SR-ISE-2026-53 (21 days) and the DOJ NICS firearms rule (effective 30 days) all count their clocks from Federal Register publication, a date not yet stated in the briefings.
- The SEC's proposal to rescind Rule 14a-8 is still moving toward notice and comment, with no date set.
- Cboe's SR-CBOE-2026-083, immediately effective, will be implemented within 60 days of the operative date, announced by Exchange Notice.
