[CALENDAR UPDATE] US President Trump will make an announcement with Commerce Secretary Lutnick at 15:30EDT/20:30BST on Wednesday

The advance-notice format itself is part of the playbook; similar trailed announcements have on past occasions produced substantive policy and on others served as negotiating theatre, so the content rather than the billing is what reprices. The transmission channels in comparable episodes have run through the dollar, with tariff escalation typically bid for USD against the targeted country's currency, through equity sector dispersion rather than the index level, and through gold and crude where the measures touch commodity flows or raise growth-risk premia. The presence of Commerce rather than Treasury or the USTR narrows the likely scope toward trade remedies and industrial measures. What matters after the fact is whether anything announced carries implementation detail, dates, rates, and legal authority, since headline tariffs without mechanics have historically been walked back or diluted, while published schedules have stuck. The tag set spanning FX majors, energy, and equity indices indicates the wire is treating this as a potential broad risk event rather than a single-market story.
