The United States military confirmed that, beginning at 10 a.m. Eastern Time (14:00 GMT) on April 13, all maritime traffic entering or leaving Iranian ports will be blocked. The directive, issued by U.S. Central Command (CENTCOM), targets vessels of every nation operating in the Gulf and the Gulf of Oman, but explicitly excludes ships merely transiting the Strait of Hormuz to non‑Iranian ports, marking a narrower scope than former President Donald Trump’s broader strait‑wide threat. This decisive action follows the abrupt end of marathon peace talks in Islamabad, where negotiators failed to secure a memorandum of understanding with Tehran. The stalemate has revived fears of renewed hostilities, prompting the U.S. to leverage maritime pressure as a bargaining chip. Financial markets reacted sharply: U.S. crude oil prices surged 8 % to $104.24 per barrel, while the benchmark Brent crude rose 7 % to $102.29. The spikes reflect investor anxiety over potential disruptions to the flow of oil and liquefied natural gas that currently passes through the Strait of Hormuz, a chokepoint responsible for roughly one‑fifth of global energy shipments. Since the February 28 launch of a joint U.S.–Israel operation against Iran, the strait’s traffic has dwindled to a trickle. Iran continues to navigate its own vessels and has allowed limited passage for foreign ships, while discussing a post‑conflict toll system for the waterway. In response to the blockade threat, Iran’s Islamic Revolutionary Guard Corps warned that any U.S. warship attempting to enforce the measure would breach the existing U.S.–Iran ceasefire—set to expire on April 22—and would be "dealt with severely." Iranian Foreign Minister Abbas Araghchi blamed the United States for the diplomatic failure, accusing U.S. negotiators of "shifting the goalposts" when a deal was "just inches away." Academic commentary echoed regional concerns. Zohreh Kharazmi, an associate professor at the University of Tehran, asserted that the United States "is not in a position to dictate" Iranian maritime movements and warned that a prolonged standoff would quickly reveal which side—"the resilience of the Islamic Republic or the resilience of global markets"—would suffer first. While the blockade targets Iranian ports, CENTCOM emphasized that it will not impede freedom of navigation for vessels merely passing through the Strait of Hormuz, a subtle but significant concession aimed at avoiding a full‑scale maritime confrontation.

The ongoing US-Israel war on Iran has taken a critical turn with Donald Trump's announcement that the US Navy would start blockading the Strait of Hormuz. This strategic waterway is crucial for global oil shipments, and any disruption could have significant economic impacts. In response, Iran's Revolutionary Guard warned that approaching military vessels to the strait would be considered a violation of the ceasefire. This development has led to a surge in oil prices, with US crude oil rising 8% to $104.24 a barrel and Brent crude oil increasing 7% to $102.29. The blockade, set to begin on Monday morning, will be implemented by US Central Command (Centcom) and will affect all maritime traffic entering and exiting Iranian ports. This move is part of a broader strategy that may include resuming limited military strikes in Iran, according to reports. The situation has drawn international attention, with Australian Prime Minister Anthony Albanese stating that his government has not been asked to participate in the blockade and is keen on continuing negotiations between the US and Iran. Meanwhile, Iranian parliamentary speaker Mohammad Bagher Ghalibaf dismissed Trump's threats, asserting that they would have no effect on the Iranian nation.

The US has announced plans to blockade the Strait of Hormuz, a vital waterway through which about 20% of global oil passes. This move comes after ceasefire talks with Iran ended without an agreement over the weekend. The blockade, threatened by President Donald Trump, aims to pressure Iran into reopening the strait, which has been effectively closed since February 28. Trump's announcement on social media stated that the US Navy will begin the process of blockading any and all ships trying to enter or leave the Strait of Hormuz. He accused Iran of 'WORLD EXTORTION' and threatened that any person who attacked US vessels would be 'BLOWN TO HELL!' However, the blockade's scope appears to have been scaled down, with US Central Command (Centcom) stating it would be confined to vessels transiting through Iranian ports, permitting passage of ships headed to ports belonging to America's Gulf allies. The blockade is set to come into effect at 10am ET (2pm GMT). The UK will not be involved in any blockade of the strait, and Australian Prime Minister Anthony Albanese has stated that his country was not asked to participate. Oil prices have surged following Trump's announcement, with US crude increasing 8% to $104.24 a barrel and Brent crude oil rising 7% to $102.29. Experts warn that the blockade could lead to higher oil prices, but much depends on its 'scope and implementation.' The managing director of research at ClearView Energy Partners, Kevin Book, noted that leaner volumes generally mean tighter markets and higher prices. Iranian and/or Houthi reprisals against Gulf producers' alternative routes could drive prices still higher. The blockade could cut off one of the Iranian regime's major sources of funding but might also have a short-term negative effect on global prices. About 100 tankers have transited the strait since the US and Israel started bombing Iran, most carrying Iranian oil products bound for China and India. Iran's Revolutionary Guards have stated that any warships approaching the strait to enforce a blockade would be considered in breach of the current ceasefire and would be dealt with strongly. Trump floated the possibility of a resumption of US strikes inside Iran, citing missile factories as one possible target.

President Donald Trump declared that the United States will commence a naval blockade of the strategic Strait of Hormuz in response to the breakdown of peace talks between Washington and Tehran held in Islamabad.In addition to the blockade, Trump warned that American forces could target Iran’s water‑treatment plants, power stations and bridges unless Tehran abandons its pursuit of a nuclear weapons capability.The announcement came after a 21‑hour round of direct negotiations between the two sides collapsed on Sunday morning, ending a brief cease‑fire that had been brokered by the United States, Israel and Iran.U.S. Vice‑President JD Vance, who led the American delegation, said Iran refused to renounce the possibility of developing nuclear weapons, while Iranian officials accused Washington of failing to earn their trust.Trump instructed the U.S. Navy to begin “blockading any and all ships trying to enter or leave the Strait of Hormuz” starting Monday at 10 a.m. ET (14:00 GMT). He also accused Iran of “extortion” for charging tolls to tankers and announced a de‑mining operation in the waterway’s central sector, although the exact number of mines remains unclear.The Iranian Revolutionary Guard warned that any warships enforcing the blockade would be deemed a breach of the cease‑fire and would be met with a strong response, insisting the strait remains under Iranian control.Two U.S. destroyers transited the strait on Saturday without incident, a move the Pentagon described as the start of a mine‑clearance mission, even as Iranian media claimed the vessels were threatened as they departed.Financial markets reacted sharply: U.S. crude oil jumped 8% to $104.24 per barrel and Brent crude rose 7% to $102.29, reflecting concerns that the blockade could disrupt the flow of roughly 100 tankers that have been paying up to $2 million each for passage.Vance reiterated that the United States seeks a clear, affirmative commitment from Iran not to pursue a nuclear weapon, describing it as the “core goal of the president.”Iranian parliament speaker Mohammad Bagher Ghalibaf argued that Tehran offered “constructive initiatives,” but U.S. demands were “excessive” and hindered an agreement, according to the semi‑official Tasnim news agency.Pakistani mediators urged both parties to avoid renewed hostilities and pledged to arrange fresh talks, emphasizing the importance of upholding the existing cease‑fire.In a televised interview, Trump warned that if a deal cannot be reached, the United States may resume bombing Iran, specifically targeting its water‑supply infrastructure, desalination plants and power generation facilities.Regional fallout continued: at least 11 people were killed in southern Lebanon amid a series of Israeli strikes, while Pope Francis called for an immediate cease‑fire, expressing solidarity with the Lebanese people.The broader conflict, now six weeks old, has claimed more than 3,000 lives in Iran, over 2,000 in Lebanon, dozens in Israel and several Gulf states, and has inflicted extensive damage on critical infrastructure across the Middle East.

The US inflation rate experienced a significant surge in March, rising to 3.3% over the year, with prices increasing by 0.9% compared to the previous month. This spike is largely attributed to the escalating conflict with Iran, which has resulted in a substantial increase in energy prices.The Consumer Price Index (CPI) for energy rose by 10.9% in March, primarily driven by a 21.2% increase in gasoline prices. This increase accounted for nearly three-quarters of the monthly all-items increase. Airfares also saw a notable rise, increasing by 2.7% in March and 14.9% higher than a year earlier.Core inflation, which excludes volatile food and energy prices, rose at a more modest 0.2% over the month and was 2.6% higher over the year. The annualized inflation rate has not exceeded 3% since summer 2024.The conflict with Iran has driven the American economy into deeper uncertainty, adding to the precariousness that began with Donald Trump's tariffs last year. The war has also led to a rise in oil prices, with US crude oil priced 10% higher than before the conflict and nearly 30% higher since the start of the year.Recent data shows that prices are affecting producers, with the gross domestic product (GDP) for the last quarter of 2025 revised down from an initial 1.4% to 0.5%. The prices index in the Institute for Supply Management's survey of managers saw its largest one-month increase in 13 years, rising from 63 in February to 70.7 in March.Consumer confidence is also falling, with the University of Michigan's closely-watched consumer confidence survey recording a 10.7% drop to its lowest level on record. Survey director Joanne Hsu noted that many consumers blame the Iran conflict for unfavorable changes to the economy.Despite the challenges, the labor market appears resilient, with employers adding 178,000 jobs in March and the unemployment rate falling to 4.3%. However, the Federal Reserve faces a tricky situation in adjusting interest rates amid the conflict, as raising rates could help curb inflation but risk destabilizing the labor market and increasing unemployment.

European airports have issued an urgent warning that jet fuel shortages could materialise within the next three weeks if the Strait of Hormuz remains closed.Airports Council International (ACI) Europe addressed a letter to EU transport commissioner Apostolos Tzitzikostas, stating the bloc is only three weeks away from a systemic shortage.The threat is linked to the ongoing US‑Israel conflict with Iran, which has effectively shut the strait—a key shipping lane for Gulf oil exports—pushing Brent crude to around $96 per barrel, up from roughly $72 before the hostilities.ACI warned that without a stable resumption of traffic through Hormuz within three weeks, a “systemic jet fuel shortage is set to become a reality for the EU.”Jet‑fuel prices have more than doubled year‑on‑year, reaching $1,650 per tonne according to IATA data. Europe’s price surge stands at 138%, while Asia has seen a 163% increase.Ryanair chief Michael O’Leary highlighted that the United Kingdom, heavily dependent on Kuwaiti supplies, is the most vulnerable market in Europe.Shipping data from Vortexa shows the last Gulf‑origin jet fuel cargo for Europe is due in Copenhagen tomorrow, following a partial delivery to Rotterdam earlier this week. The final tanker bound for the UK arrived in Kent on Tuesday.More than 60% of Europe’s jet fuel traditionally comes from Gulf refineries, with over 40% shipped via the Hormuz corridor. The blockade forces European buyers into direct competition with Asian carriers for alternative cargoes.Australian investment bank Macquarie notes that jet fuel lacks the pipeline alternatives available to crude oil, making the market especially vulnerable. Even if shipments resume, the refined‑product market could take two to three months to normalise, lagging behind crude markets.Airlines have already begun trimming schedules and raising fares, a trend that will feed into broader inflationary pressures. A genuine shortage could force travelers and businesses to postpone trips and shipments, deepening economic damage.ACI called for proactive EU monitoring and action, warning that the peak summer travel season—critical to many economies—could be hit hard if fuel supplies falter.IATA director‑general Willie Walsh cautioned that even with the strait reopened, restoring adequate supply will take months due to disrupted refining capacity in the Middle East. IATA had previously projected a 4.9% year‑on‑year growth in passenger traffic for 2026.

Japan's Prime Minister, Sanae Takaichi, announced on Friday that the country will release additional oil reserves early next month, equivalent to roughly 20 days' worth of oil, to ensure a stable supply of crude oil. This move comes as concern grows over energy shortages caused by the crisis in the Middle East.This will be the second time Japan has dipped into its strategic reserves since the US-Israel war on Iran started in February. Last month, Takaichi approved the release of 50 days' worth of oil, the government's biggest ever release, in an attempt to head off a spike in prices.Japan has enough oil in reserve to last 230 days, but it also imports 95% of its crude oil from the Middle East, most of which is transported through the Strait of Hormuz. The country is trying to secure oil from locations that do not ship via the Strait of Hormuz, amid uncertainty over whether the waterway will fully reopen after a two-week conditional ceasefire announced by Donald Trump this week.By May, Japan should be able to secure more than half of its oil imports via other routes, Takaichi said, although she did not provide details. The industry ministry has said that potential new sources for imports could include Yanbu on Saudi Arabia's Red Sea coast and the Port of Fujairah in the United Arab Emirates.The decision to tap into oil reserves for a second time came as pressure grew on Japan's government to resist US pressure to become militarily involved in the conflict. More than 100 demonstrations were held across the country on Wednesday, with protesters urging Takaichi to abide by the postwar constitution, which forbids Japan from using the threat or use of force as a means of settling international disputes.

The recent ceasefire between the United States and Iran may provide temporary relief, but the oil crisis triggered by their conflict is far from over. After 40 days of fighting, the two nations agreed to a two-week ceasefire, with negotiations set to begin in Pakistan's capital, Islamabad.One of the key points in Iran's 10-point proposal is allowing shipping to resume through the Strait of Hormuz, a critical waterway through which 20 percent of the world's oil and gas is shipped during peacetime. The strait has been effectively closed since the start of the war, causing global oil and gas prices to soar.Following the announcement, oil prices dropped to $92 on Wednesday, down from over $110 for much of the war. However, delays in restarting production and transport mean the energy crisis is far from over. For ships to continue operating, they need certainty about security during the next two weeks of the ceasefire.Even with the waterway reopened, it will take weeks for large oil tankers – now scattered thousands of miles away – to return to the Gulf to collect the millions of barrels sitting in large reservoirs. With very few tankers able to load or unload and their onshore storage full, producers began shutting wells, causing regional oil output to plummet despite efforts to reroute limited volumes via overland pipelines.Economists warn that the true impact on grocery bills will likely persist throughout 2026 and into 2027. Additionally, it will take years for the Gulf energy industry to repair facilities damaged or destroyed during the war.Shipping data shows that combined exports from Iraq, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates fell from 469 million barrels in February to 263 million barrels in March – a decline of 206 million barrels, or 44 percent. Iraq's crude exports have been hit the hardest, falling 82 percent from 94m barrels in February to 17m in March.The 206 million barrels of Gulf oil lost since the start of the war would fill approximately 103 Very Large Crude Carriers (VLCCs), the workhorse supertankers of the global energy trade. A single VLCC stretches nearly 330 metres (1,080 feet) in length, nearly the same height as the Eiffel Tower in Paris.To put that in more practical terms, if you drove a pick-up truck that averages 24 miles per gallon (or 10 litres per 100km), one barrel of crude oil would carry you about 730km or 450 miles. That is about the distance from New York City to Cleveland, Ohio.For much of the war, oil has traded above $100 per barrel, hitting a peak of nearly $128 on April 2. The value of 206 million lost export barrels at various oil prices is significant, with Brent crude being the global benchmark.

The recent ceasefire between the US and Iran offers a glimmer of hope for the energy crisis that has been exacerbated by the conflict in the Strait of Hormuz. However, the deal's stability is already being questioned, with Iran claiming that Israel's attacks on Lebanon breach the agreement. Even if the ceasefire holds and hundreds of tankers stranded in the Gulf start to transit once more, analysts fear that it will not be enough to return the flow of oil, gas, chemicals, and other vital items to pre-crisis levels. An estimated 2,000 vessels with about 20,000 seafarers onboard have been trapped in the Gulf since the outbreak of the conflict. Shipping analysts and owners have cautioned that even a temporary ceasefire does not provide a sufficient guarantee that it is safe to make the passage, particularly because Iran's foreign minister has stated that transit will be under Iranian military management. Many questions remain for shipowners and their captains over whether it is safe to navigate through the strait. The disruption has been compounded by the forced shutdown of oil and gas production across the Gulf as storage facilities reached capacity. In addition, many key energy production sites have been damaged by drone attacks. Experts have said it could take months or years to fully restore the Gulf's energy production. Energy markets have fallen sharply on the hope that millions of barrels of crude oil and gas trapped in the Gulf could soon help to relieve a crisis that the International Energy Agency has said is more serious than the energy flashpoints in 1973, 1979, and 2022 combined. However, traders are also expected to price in a continuing 'geopolitical risk premium' to reflect uncertainty over whether the ceasefire will hold.
