I. Market Outlook

Core Events

Iran’s Supreme Joint Military Command on Thursday announced the closure of the Strait of Hormuz, banning oil tankers and merchant vessels, and warned any attempting passage will be targeted. U.S. May CPI rose 4.2% YoY, the largest increase since April 2023, driven by a sharp rise in energy prices amid Middle East tensions.

Market Reaction

All three major U.S. indexes fell together for the first time this week; S&P and Nasdaq closed at one-month lows, Dow down 1.87%. WTI crude settled up 2.07% at $90.03/bbl. Gold plunged 3.56% to $4,108/oz.

Exclusive Insight

Iran’s “official closure” marks a qualitative escalation — from de facto blockade to formal declaration. Brent crude settled at $93.10, with limited gains as markets price the closure as “not long-lasting.” CPI at 4.2% is the highest since April 2023, but reaction was muted — traders still bet on a October hike, not earlier.
