The disruption will sting lower than it might need in some other week, with many American merchants out for the Thanksgiving vacation.
“Whilst our 2026 outlook might be called ‘Anything but dull’, the last 24 hours have been ‘everything dull’ with the U.S. out for Thanksgiving, and few headlines elsewhere,” wrote Deutsche Financial institution’s Jim Reid to shoppers this morning “Even an overnight outage at the CME, which means many futures contracts (including U.S. equity futures) haven’t traded since around 2.45am London time, hasn’t really been noticed!”
