Iran threatens to retaliate against Gulf ports for US blockade

Summary

Oil prices surged when trade reopened on Monday, with no sign of a swift reopening of the Strait of Hormuz to ease the biggest ever disruption in supplies. Since the war started on February 28, Iran has effectively shut the strait to all vessels except its own, saying passage would be permitted only under Iranian control and subject to a fee. U.S. President Donald Trump said Washington would now block Iranian vessels and any ships that paid such tolls.

The ceasefire, which halted six weeks of U.S. and Israeli airstrikes, is under threat, with only a week left to run. Washington said Tehran rejected its demands at weekend talks in Islamabad, the highest-level discussions since Iran's 1979 Islamic Revolution. The U.S. military's regional Central Command said the blockade would start at 10 a.m. ET (1400 GMT) on Monday, to be "enforced impartially against vessels of all nations" entering or leaving Iranian ports in the Gulf and the Gulf of Oman. Two Iranian-linked tankers, the Aurora and New Future, laden with oil products, left the strait on Monday before the U.S. blockade was due to take effect, according to LSEG data. An Iranian military spokesperson called any U.S. restrictions on international shipping "piracy," warning that if Iranian ports were threatened, no port in the Gulf or Gulf of Oman would be secure. Any military vessels approaching the strait would violate the ceasefire, Iran's Revolutionary Guards said. On Sunday, Trump had posted on social media that ships paying Iran an "illegal toll" would not be granted safe passage, adding, "Any Iranian who fires at us, or at peaceful vessels, will be BLOWN TO HELL!" 'ZERO LESSONS LEARNED' SAYS TEHRANWith the war unpopular at home and rising energy prices causing political blowback, Trump paused the U.S.-Israeli bombing campaign last week after threatening to destroy Iran's "whole civilisation" unless it reopened the strait. Israel has continued to bombard Iran-backed Hezbollah in Lebanon and on Monday Israeli troops launched an attack to seize a key south Lebanon town from the group. Israel and the U.S. have said the campaign against Hezbollah was not part of the ceasefire, while Iran has insisted it is. Iran has ignored the demand to open the strait, while bringing new demands to the talks, including recognition of its control of the waterway, lifting of sanctions and the withdrawal of forces from U.S. military bases across the Middle East. Trump has declared victory, despite failing to achieve the objectives he set out at the start of the war: to eliminate Iran's ability to strike its neighbours, end its nuclear programme and make it easier for Iranians to topple their government. Iran retains missiles and drones that can hit Gulf neighbours, and a stockpile of uranium enriched to near bomb-making levels. Tehran's leadership, which faced a popular uprising at the start of the year, has withstood the U.S. onslaught with no sign of organised opposition. U.S. officials said Iran had rejected demands at the talks to give up the uranium stockpile, end future enrichment and halt funding for its regional allies - positions carried over from negotiations Trump abandoned two days before the war. Washington still hopes that Iran will seek peace and a chance to begin rebuilding from damage that has deepened an economic crisis that provoked pre-war domestic unrest. Also Read: Can Trump’s Iran blockade plunge India into an 'everything crisis'? But emboldened Iranian officials say they are in a stronger position than before, and will make a deal only if the U.S. makes further concessions. Iran had "encountered maximalism, shifting goalposts, and blockade" from the United States at the talks, said Foreign Minister Abbas Araqchi. "Zero lessons learned," he added. "Good will begets good will. Enmity begets enmity." OIL BENCHMARKS UNDERSTATE DISRUPTIONBenchmark oil prices, which had eased last week after the ceasefire was announced, surged by around 7% on Monday, back above $100 a barrel. Traders say the main benchmarks - used to set prices for trillions of dollars' worth of commodities worldwide - actually understate the severity of a disruption with no precedent in modern times. The benchmarks are based on contracts to deliver oil one to two months ahead. Physical supplies, however, are already tight, with some refineries paying record premiums of up to $50 above the benchmarks to get their hands on oil now. If the benchmarks catch up to physical prices, industries would face massive cost rises. A reckoning could be approaching as the last Gulf oil shipped before the war runs out. "Reopening the Strait has become the market's most time-sensitive priority," JP Morgan analysts said in a note. "The last tanker to clear Hormuz on February 28 is expected to reach its destination around April 20, marking the point at which pre-closure barrels are fully exhausted from the global supply chain." Trump has long said a bump in U.S. gasoline prices would be short-lived. But he told Fox News' "Sunday Briefing" that they could stay high through November's midterm elections. Iran's chief negotiator, Mohammad Baqer Qalibaf, posted a map of Washington-area gasoline prices on social media with the comment: "Enjoy the current pump figures. With the so-called 'blockade'. Soon you'll be nostalgic for $4-$5 gas." (You can now subscribe to our Economic Times WhatsApp channel) (You can now subscribe to our Economic Times WhatsApp channel)

Japan’s Defense Ministry said Friday that Iran used its geographical advantage to “inflict unbearable costs at a relatively low military expense,” effectively closing the Strait of Hormuz by indicating that it had laid naval mines, Kyodo News reported.

The ministry said Japan would strengthen its defense capabilities based on lessons from the US-Iran war, including by using defense equipment also operated by allies and like-minded partners to help ensure rapid supplies from other countries. It also stressed the need to maintain sufficient missile stockpiles and be prepared to quickly increase defense equipment production in an emergency, according to its first report analyzing the Iran war since February.

The US-Israeli war against Iran began on Feb. 28, with attacks targeting military, nuclear and infrastructure sites across the country. Iran responded with missile and drone strikes against Israel and US military facilities across the region.

The Japanese report also said the country should take its own geographical characteristics into account when developing combat strategies, including the fact that it is surrounded by sea. The report noted the US use of AI to accelerate decision-making and operations, citing attacks on around 1,000 targets within 24 hours, while also highlighting the risk of AI making incorrect judgments.

“It is important to establish a process that maximizes the benefits of AI while ensuring appropriate human involvement,” the ministry said. The report comes ahead of a planned revision of Japan’s key security documents by the end of this year.

A major offensive by Yemen's Houthis to seize control of the gateway to the Red Sea has left more than 120 people dead, sources told AFP Friday, the country's deadliest clashes in years. Fighting erupted on Thursday, after the Iran-backed Houthis launched a ground assault along with rocket and drone attacks near coastal areas, vying for control of the narrow Bab al-Mandab strait at the Red Sea's southern entrance.

Yemen, embroiled in more than a decade of civil conflict, in July became the latest country to be drawn into the Middle East war as the Houthis upended a 2022 truce with the Saudi-backed government. Since then, the Houthis have imposed a maritime blockade of Saudi Arabia and repeatedly attacked its ships in the Red Sea -- a vital alternative route for oil exports after Iran all but halted Gulf shipments by blockading the Strait of Hormuz.

The rebels are now trying to tighten their hold over the Red Sea, one of the world's busiest shipping lanes, which they have disrupted with attacks on passing vessels since the Gaza war broke out in 2023. The Houthi offensive aims to cut off the government-held port city of Mokha, under fire for weeks, and advance towards areas bordering the Bab al-Mandab, military sources told AFP.

The rebels have seized elevated sites overlooking government positions near the Red Sea and the city of Taiz further inland, a military source and a Taiz official told AFP, requesting anonymity. The Houthis could target ships from these elevated positions, they said.

The toll rose to 129 on Friday, according to an AFP tally compiled from several sources, up from an earlier count of 81. A Yemeni military official speaking on condition of anonymity told AFP that 66 of his men had been killed, while medical and military sources close to the Houthis said at least 62 militants had died.

Another medical source said a civilian had also been killed. Although the Houthis do not control areas bordering Bab al-Mandab, they hold the key port city of Hodeida north of Mokha. "They are going for Bab al-Mandab," said Mohammed al-Basha, of the US-based risk advisory Basha Report.

The Houthis want to control the hills overlooking Bab al-Mandab and Mokha before attacking the coast, a Yemeni official in Aden, the government's base since it was ousted from the rebel-held capital, Sanaa, in 2014. The government has sent reinforcements to Taiz from Aden on Saudi orders, he said.

"The Houthis feel that if they capture Bab al-Mandab or Mokha port they will be in a better position of power to negotiate with the government and the Saudis," Basha added. With Iran's closure of Hormuz, the Bab al-Mandab chokepoint has gained increased importance as a transit route for oil from Saudi Arabia, the world's biggest exporter of crude.

The narrow waterway connects the Red Sea -- and, via the Suez Canal, the Mediterranean -- to the Indian Ocean. In July, a fragile truce between the Houthis and the government fell apart after the rebels welcomed an Iranian plane to Sanaa, setting off a spate of attacks.

They later announced a maritime blockade of Saudi Arabia and began hitting its ships and territory.

If passed, the resolution would follow up on one adopted on June 12 of last year declaring Iran in breach of its non-proliferation obligations for not fully cooperating with an investigation into uranium traces found at undeclared sites. Israel started bombing Iran's nuclear facilities the next day, soon joined by the U.

S. Iran's uranium-enrichment plants were destroyed or badly damaged. Iran has not let International Atomic Energy Agency inspectors return to the bombed sites since then or verify what remains of its stocks of enriched uranium, some of which was enriched to up to 60% purity, a short step from weapons grade.

FRESH DIPLOMATIC ESCALATION A resolution by the IAEA's 35-nation board reporting Iran to the Security Council would also be the culmination of a standoff over IAEA access to those sites, since the board has passed two resolutions in the past year demanding Iran declare its enriched uranium stocks and grant the IAEA full access to verify them.

"(The board) requests the (IAEA) Director General to transmit this resolution and the previously adopted resolutions ... to all Members of the Agency and to the Security Council and the General Assembly of the United Nations," said the latest resolution draft seen by Reuters.

It also "reiterates its call upon Iran to urgently remedy its non-compliance with its Safeguards Agreement by taking all steps deemed necessary by the Agency and the Board, so that the Director General can provide the necessary assurances regarding the correctness and completeness of Iran's declarations".

The draft has not yet been formally submitted to the board and negotiations over the exact wording are ongoing, diplomats said. Whenever the four powers have submitted a draft resolution on Iran in recent years, it has passed. Concrete action by the Security Council against Iran is unlikely since Tehran's allies Russia and China are permanent, veto-wielding members.

IAEA CONCERNS OVER ENRICHMENT Iran has often retaliated following IAEA board resolutions against it by escalating its nuclear activities or scaling back cooperation with the IAEA, but its options for both are currently extremely limited. It is unclear what other repercussions there might be on Tehran's conflict with the U.

S. As a party to the nuclear Non-Proliferation Treaty (NPT), Iran has the right to develop nuclear technology, including enrichment, for peaceful purposes. Iran says it would never produce nuclear weapons. It is, however, the only country to enrich to 60% without making a bomb.

The IAEA has said the amount it has enriched to that level is of serious concern. The IAEA estimates Iran had 440.9 kg of uranium enriched to that level before its sites were bombed. That is enough, if enriched further, for 10 nuclear weapons, according to an IAEA yardstick.

The US and its allies Britain, France and Germany are pushing other countries on the UN nuclear watchdog's board to pass a resolution next week reporting Iran to the UN Security Council for the first time in 20 years, diplomats said on Friday. If passed, the resolution would follow up on one adopted on June 12 of last year declaring Iran in breach of its non-proliferation obligations for not fully cooperating with an investigation into uranium traces found at undeclared sites.

The US launched an air war against Tehran on February 28 in which, together with Israel, it destroyed or badly damaged Iran's uranium-enrichment facilities. Iran has not let International Atomic Energy Agency (IAEA) inspectors return to the bombed sites since then or verify what remains of its stocks of enriched uranium, some of which was enriched to up to 60% purity, a short step from weapons grade.

Resolution would be culmination of standoff over IAEA's access to nuclear sites A resolution by the IAEA's 35-nation board reporting Iran to the Security Council would also be the culmination of a standoff over IAEA access to those sites, since the board has passed two resolutions in the past year demanding Iran declare its enriched uranium stocks and grant the IAEA full access to verify them.

A draft text for the resolution has yet to be formally submitted to the board and negotiations between countries over the exact wording are ongoing, diplomats said. A draft is usually formally submitted early in the week of a board meeting. As a party to the nuclear Non-Proliferation Treaty (NPT), Iran has the right to develop nuclear technology, including enrichment, for peaceful purposes.

Iran says it would never produce nuclear weapons. It is, however, the only country to enrich to 60% without making a bomb. The amount it has enriched to that level is "a matter of serious concern" to the IAEA. The IAEA believes well over 200 kg of that highly enriched uranium has survived the bombardments and is held in a tunnel complex at Isfahan and at the Natanz facility.
