[basis: absence] GDELT unavailable. Two distinct window-limited searches ('Iran government IRGC ... threatens close Strait of Hormuz international shipping' and 'Iranian official declared would shut Strait of Hormuz shipping ... Reuters') yielded articles on unrelated fresh threats, regional flights, vessel strikes, and an Oman meeting, but no official- or wire-tier past-tense confirmation of a formal Iranian threat to close the strait to international shipping. The September 25 CBS News 'trade fresh threats' title does not establish the specific closure declaration. Absence-based assessment.

Bayesian Strait of Hormuz Crisis shows 67% escalation probability despite a 'sufficient' 50% bargaining range; prior confirmed harassment/mine/seizure incidents establish an escalatory pattern that plausibly extends to explicit closure rhetoric distinct from physical incidents already confirmed.
