[CALENDAR UPDATE] US President Trump will make an announcement at 14:00EDT/19:00BST on Monday, according to the White House

The precedent with unscheduled Trump announcements is that the trade-sensitive ones, particularly anything tariff-related, have tended to hit equities, the dollar, and affected bilateral FX crosses in the minutes around the remarks, while purely domestic or personnel items have passed with little lasting effect. The timing here is notable: an afternoon Washington slot falls in thin late-European, mid-US liquidity, which has previously amplified the initial move when the substance turned out to be market-relevant. Prior form is that advance-notice announcements flagged hours ahead skew toward substantive policy rather than routine remarks, though that is a tendency, not a rule. Worth noting is that the notice itself carries no subject, so positioning ahead of it is speculative; the established pattern is that desks stay light and the reaction, if any, comes on the substance. The follow-on to watch is whether the White House or wires pre-brief the topic before the scheduled time, which in past episodes has front-run the official remarks.
