Hormuz Weekly Attacks Reach Record High Since Iran War Began as Exports Rebound

Hormuz

Maritime security sources reported that attacks, attempted attacks and harassment incidents against tankers in the Strait of Hormuz reached their highest level last week of any week since the Iran war began. The surge coincides with a larger export push by Persian Gulf producers. Nearly 20 commercial ships, mostly tankers, have come under attack over the past month while transiting Hormuz, the Persian Gulf or waters off Oman. One specific incident involved the Panama-flagged tanker MT On Peace, where eleven Indian crew members were injured.

Transit volumes have not fallen in published data, but the combination of higher attack frequency and the export rebound creates a narrower operational window for owners. Vessels that continue to use the strait face longer routing alternatives only via the Cape of Good Hope, adding substantial time and fuel cost. No public figures exist for the exact share of traffic that has already diverted, but the pattern of repeated incidents suggests owners will test alternative routing more aggressively in coming weeks.

The additional-premium regime for Hormuz has not received fresh published quotes this week. However, the record attack count supplies the clearest recent evidence that underwriters will face pressure to widen the geographic scope or raise the per-transit loading for vessels declaring Hormuz passages. Cover withdrawal remains unconfirmed in any source, yet the sustained tempo of incidents provides the factual basis for such decisions if the pattern continues.

Black Sea

Strikes on commercial vessels in the Black Sea produced one confirmed death, seven injuries and the sinking of at least one ship, with Bulgaria calling off the search for missing crew. Indian authorities condemned attacks on four vessels that left two of their nationals injured. Russia has denied responsibility for the incidents.

These events directly affect routing for vessels loading or discharging at Ukrainian or Russian Black Sea ports. Owners must weigh the exposure against any remaining insurance availability. No aggregate weekly transit count for the Black Sea appears in the supplied reporting, so the scale of any volume shift cannot yet be quantified.

War-risk premiums for the Black Sea have not been restated in this week's sources. The human cost and the denial of responsibility together indicate that the additional-premium layer for this theatre will remain under review rather than relaxed.

Bab-el-Mandeb / Red Sea, Suez, Malacca / Singapore Strait, Gulf of Guinea, Baltic, Taiwan Strait / South China Sea

No new attack data or routing shifts were published for these chokepoints in the supplied items. Their risk pictures therefore register as unchanged on the basis of available evidence.

Insurance Transmission

Breach clauses and additional-premium schedules for Hormuz and the Black Sea are the immediate transmission mechanisms. The record Hormuz attack week supplies fresh justification for underwriters to adjust the additional-premium per transit or to narrow the list of acceptable flags and operators. K&R and crew war-risk bonuses have not received new published figures, yet the eleven Indian crew injuries on MT On Peace illustrate the exposure that those bonuses are meant to address.

Where cover is being withdrawn or re-priced cannot be confirmed from the evidence. The sources instead document the underlying incident count that will drive those commercial decisions. Owners and charterers therefore operate with an information gap on exact premium levels until the next renewal cycle or until insurers issue fresh circulars.

Crew Dimension

Crew exposure is documented in two theatres. In the Strait of Hormuz, eleven Indian seafarers were injured in a single tanker attack. In the Black Sea, strikes left at least one seafarer dead and others injured, prompting India to state that targeting of seafarers must end. No updated ITF or IBF warlike-operations area designations appear in the reporting.

Transit bonuses and refusal rights therefore rest on existing designations and individual contracts. Families of the injured and missing crew face immediate uncertainty. Manning agencies will be asked to supply replacement crews for vessels continuing to trade in the affected areas, while serving seafarers weigh whether existing war-risk compensation remains adequate for the elevated threat level.

Second- and Third-Order Consequences

Charterers reliant on Gulf crude face higher freight or insurance pass-through costs if Hormuz premiums rise. Energy traders must decide whether to accelerate purchases ahead of potential further tightening. Flag states whose vessels appear in incident reports may encounter additional scrutiny from insurers. Port agents in Oman and the UAE will see increased demand for security assessments and convoy coordination. Seafarer supply countries, particularly India, confront pressure to negotiate higher compensation or to restrict nationals from certain voyages.

Counter-Case

The strongest alternative reading is that the Hormuz attack surge reflects a temporary Iranian response to the export rebound rather than a sustained campaign that would force structural rerouting. Under this view, once the immediate political signal is delivered, incident rates could fall back toward prior weekly averages. Evidence that would support this reading would be a measurable drop in reported attacks over the next two reporting cycles while export volumes remain elevated. The supplied sources do not yet contain that follow-on data.

What We Know, What We Do Not Know and Eagle Assessment

What is known: attacks in Hormuz reached a weekly record; nearly 20 ships affected in the past month; one tanker suffered eleven Indian crew injuries; Black Sea strikes produced fatalities and a sinking. What is not known: exact additional-premium levels now being quoted; the share of traffic that has diverted; any fresh ITF/IBF area designations. Eagle Assessment: the Hormuz risk elevation is the clearest movement this week and will transmit first into insurance pricing and crew compensation negotiations; is high on the incident count itself and medium on the durability of the surge.

Questions Decision-Makers Should Be Asking

• Which underwriters have signalled they will widen Hormuz additional-premium zones or raise loadings effective this month?
• Has any flag administration issued fresh guidance to owners on Hormuz or Black Sea transits?
• What compensation adjustments are Indian manning agencies negotiating for crew serving on vessels routing through Hormuz?
• Are charterers already inserting new war-risk clauses that allow refusal of Hormuz or Black Sea calls without penalty?
• Which security firms have published updated convoy or escort availability for the Strait of Hormuz?
• Do any sources indicate a measurable decline in Hormuz attack frequency in the first days of the current week?

Triggers to Watch

Next 7 days: publication of any fresh weekly attack tally for Hormuz that falls materially below last week's record; confirmation or denial of new additional-premium circulars from leading war-risk syndicates.

Next 30 days: first measurable drop in declared Hormuz transits in public AIS-derived data; any ITF or IBF statement expanding warlike-operations areas; outcome of the next round of U.S.-Iran talks referenced in reporting.

Next 30 days for Black Sea: resumption or continued suspension of search operations; any Greek or Indian government restriction on national-flag or national-crew voyages in the theatre.
