Iran Threatens More Hormuz Attacks as Shipping Falls and Sanctions Widen

The latest escalation came as oil shipments through the Strait of Hormuz were recovering despite the war. Bloomberg reported on October 7 that oil flows had returned to nearly 80% of prewar levels, with prices remaining choppy.

That recovery was increasingly exposed to attacks. Times of India Top Stories reported at least twelve incidents involving various types of vessels during the previous week, describing the highest weekly level of tanker attacks since the Iran war began.

Iran's account of the waterway was sharply different from the evidence of continuing traffic. According to Mehr News (English), Senior Iranian Commander Brigadier General Naghdi said Hormuz remained closed and under the full control of Iran's armed forces until the country's demands were met.

On October 7, CBS Top Stories reported that an Islamic Revolutionary Guard Corps official said Iran would soon block routes it deemed illegal. That threat suggested further restrictions even while ships were still making the passage.

Also on October 7, a tanker off Qatar's north coast reported being hit by multiple projectiles, according to Arab News, citing the UKMTO maritime agency. Casualties were reported, but their number was unspecified.

By October 8, the disruption was visible in shipping data. The Hindu, citing analytics firm Kpler, reported that just seven commodity vessels had crossed the strait on October 6, the lowest daily figure since July 23. Business Line - Home reported that crude oil crossing the strait had fallen 27% from its wartime high.

The attacks also extended beyond the strait itself. Euronews reported on October 8 that two commercial vessels had been hit within 24 hours, one off Qatar and another off Fujairah in the Gulf of Oman. The outlet described the incidents as signs of an expanding Iranian campaign, citing suggestions from IRGC-affiliated outlets that operations had widened.

Washington increased economic pressure on October 8. According to CNBC, the Treasury sanctioned seventeen tankers linked to Iran's shadow fleet as part of the Trump administration's military and economic campaign. The Hindu subsequently reported that two Mumbai-based firms and five Indian nationals also faced sanctions over alleged Iranian oil trade.

On October 9, Middle East Eye reported that the IRGC Navy's political deputy said its forces were carrying out nightly operations against vessels it considered to be violating its rules. Mehr News (English) also reported an advisor's warning that a few routes described as illegal and created through blasting would soon be blocked.

Hormuz is neither operating normally nor fully shut to commercial traffic. Iranian officials describe it as closed and under their control, but shipping data records continuing crossings. Assessments of the recovery also differ: Financial Times World reported that transit had approached 90% of prewar levels last month before falling sharply, while Il Post reported on October 9 that oil exports had nearly returned to prewar levels and Iran's control was weakening. Those reports do not provide a single, consistent measure of current flows.

Oil prices have risen with the renewed attacks. cnn.com reported on October 8 that supply concerns and record tanker attacks had pushed prices higher as crossings fell to a two-month low. The IRGC commander-in-chief, meanwhile, called security in the Persian Gulf and Hormuz a red line, according to IRNA English.

The reported U.S. military position has shifted. NBC News reported on October 8 that President Donald Trump was considering renewed large-scale operations in Iran. An October 9 headline from Bloomberg said Trump had ruled out strikes before the midterms.

The immediate test is whether Iran follows through on its threat to block additional routes, and whether the reported nightly operations further reduce crossings. The available coverage does not specify the demands that Iranian officials say must be met before Hormuz reopens.

The sanctions campaign also has an unresolved practical test: how much Iranian oil trade it actually prevents. Iran International (English) reported that the U.S. Treasury said its latest action effectively neutralized most of Iran's remaining shadow fleet. That is the Treasury's assessment, not an independently established outcome in the supplied coverage.
