Hormuz can remain technically open while becoming commercially unbearable
Pressure without complete closure
Attacks on energy tankers around the Strait of Hormuz reached their highest weekly level since the Iran war began. Maritime-security sources recorded at least 12 attacks, attempted attacks or harassment incidents between September 28 and October 5. The International Maritime Organization had verified nine incidents by October 7.
The activity included drone overflights, radio challenges, surveillance and physical attacks. Twelve crew members were reportedly injured when an unidentified projectile struck the Panama-flagged tanker On Peace.
Iran does not need to close Hormuz completely to produce strategic results. Persistent, unpredictable attacks can raise insurance premiums, reduce available crews, delay loading schedules and force shipowners to demand higher rates.
The economic weapon
This resembles calibrated maritime coercion: allow enough traffic to prevent an overwhelming international response while making every transit more expensive. Gulf producers are trying to maintain exports, but greater volumes also provide more targets.
The consequences will extend beyond oil-importing industrial economies. Higher fuel, freight and insurance costs eventually reach food-import-dependent markets across the Horn of Africa. Somaliland is particularly exposed because transport, electricity generation and food distribution remain heavily dependent on imported fuel.
WARYATV Assessment
The central danger is not necessarily a dramatic Iranian declaration closing Hormuz. It is the normalization of an insecure passage where attacks become commercially routine. If insurers begin treating Hormuz as a persistently unmanageable war zone, the economic effect could approach a partial closure even while ships continue sailing.
