Executive assessment
The leading issues this week were Canada’s imposition of retaliatory tariffs as bilateral talks stall and the U.S. Treasury expands Iran sanctions across aviation infrastructure.
Priority business policy risks
1. Canada imposes retaliatory tariffs as bilateral talks stall
Priority: High | Change since last week: New (provisional historical baseline)
Development: Canada imposed tariffs ranging from 15% to 50% on approximately $20 billion of U.S. goods, following U.S. duties on a similar value of Canadian products.
Business exposure: The measures raise costs inside supply chains designed around duty-free North American trade and increase the risk that sourcing and investment decisions will be used as bargaining tools.
Next milestone: Exclusion requests, additional U.S. measures, Canadian relief programs and pressure to restart talks.

2. Treasury expands Iran sanctions across aviation infrastructure
Priority: High | Change since last week: New (provisional historical baseline)
Development: Treasury imposed 36 sanctions on Iranian airlines and support networks in Turkey, the UAE, Malaysia and Kazakhstan and suspended three aviation authorizations.
Business exposure: The action restricts non-U.S. airlines operating U.S.-origin aircraft into Iran and narrows channels for safety parts and emergency services, creating extraterritorial operational risk.
Next milestone: Flight cancellations, lessor instructions, parts stoppages, secondary-sanctions screening and requests for humanitarian clarification.

3. Reported tanker strike brings conflict closer to Iran’s main oil hub
Priority: High | Change since last week: New (provisional historical baseline)
Development: Iranian media reported that an Iranian tanker near Kharg Island was struck by four U.S. missiles. No casualties were reported; neither U.S. Central Command nor Iranian authorities had independently confirmed the account at cutoff.
Business exposure: Kharg historically handled most Iranian crude exports. Even under blockade, direct attacks near the hub increase the probability of retaliation against regional energy assets.
Next milestone: Military confirmation, Iranian response and higher war-risk pricing.

4. U.S. strikes turn Iranian oil carriers into military targets
Priority: High | Change since last week: New (provisional historical baseline)
Development: U.S. Central Command said American forces struck three Iranian crude-oil tankers after Iran launched ballistic missiles at two U.S. Navy ships. CENTCOM reported no American injuries.
Business exposure: Commercial hulls carrying strategic commodities are now direct objects of force. Ownership, flag, routing and cargo documentation may affect both targeting and insurability.
Next milestone: Iranian retaliation, revised war-risk terms, rerouting and scrutiny of OPEC+ policy.

5. Iran prepares a restricted zone and controlled Hormuz corridor
Priority: High | Change since last week: New (provisional historical baseline)
Development: Iran said it will publish maps for a new restricted Gulf zone and a shipping corridor through Hormuz; vessels entering the restricted area would face sanctions.
Business exposure: The proposal would add an Iran-administered regulatory layer to U.S.-protected maritime movements, creating conflicting instructions and enforcement risk.
Next milestone: Publication of coordinates, vessel categories, transit conditions and responses from Oman and the United States.

Hormuz traffic collapse becomes a physical supply constraint. Average commodity-vessel traffic over 10 days fell to about 10 ships daily, the lowest since May. Only two commodity vessels transited on Saturday. Source
Houthi attacks extend the war to Saudi energy infrastructure. Iran-backed Houthi forces attacked four cities in southern Saudi Arabia, injuring 73 people and setting fires at Saudi oil installations. Source
