🌐 PIS BRIEF — 071735ZSEP2026

📌 TL;DR

Iran is poised to declare a “prohibited zone” around the Strait of Hormuz, jeopardising the free flow of roughly one‑fifth of global oil shipments. The move could force a rapid U.S. naval response and push energy prices sharply higher, affecting consumers worldwide.
