US President Trump says US will respond to Iranian attacks, reports Fox

Statements of intent to respond, delivered without operational detail, sit in the pre-escalation phase of a familiar sequence: rhetorical commitment first, then attribution of authorship to the original attacks, then any kinetic or sanctions follow-through. In comparable US-Iran episodes the tape has typically moved on the character of the response rather than the promise of one, with the distinction that matters being whether retaliation targets Iranian assets directly or proxies and infrastructure, since the former carries the higher tail risk of a tit-for-tat cycle. The established market pattern in such episodes is a haven bid in gold, the franc and the yen, an oil premium keyed to Gulf supply and shipping risk rather than headline noise, and equities selling off on the uncertainty gap between statement and action. The verbal channel here is informal, a comment relayed through a friendly outlet rather than a formal address or a Pentagon briefing, which historically has carried less informational weight than official channels and is consistent with positioning rather than an imminent operation. What bears watching is any movement of carrier or air assets, sanctions announcements, and Iranian counter-rhetoric, which in past sequences have been the tells that separate signalling from escalation. Absent those follow-ons, the risk premium in crude and havens from a headline of this kind has tended to fade rather than build.
