British Chancellor Rachel Reeves has stepped up her criticism of Donald Trump's war on Iran, describing it as a 'mistake' that has destabilized the global economy and damaged living standards around the world.In a marked fraying of the transatlantic relationship, Reeves said Trump's decision to break off from diplomatic talks with Iran and launch airstrikes seemed to have left the president in a worse place than he started.“I think it was a mistake to end those [talks with Iran] and to enter into conflict, because I'm not convinced that we are safer today than we were a few weeks ago,” she told an event in Washington.Reeves' comments added to blunt criticism of Trump she made just before flying out on Tuesday, when she expressed frustration at the 'folly' of his decision to go to war without a clear exit plan.The criticism adds to an increasingly tense atmosphere between Downing Street and the White House, with Trump's attacks on Prime Minister Keir Starmer becoming increasingly personal.The IMF warned on Tuesday that a further escalation in the Iran war could trigger a global recession that would affect the UK more than any of the other G7 nations.Reeves called for the urgent reopening of the strait of Hormuz to calm global energy prices, saying the lack of clear US targets in negotiations with Iran had worsened the situation.“We had the waterway open a few weeks ago. So, if now the objective is to reopen the strait of Hormuz? Well it was open at the beginning of this conflict,” Reeves added.Reeves said she had come to the IMF meetings to “deliver that fair message” that the conflict in the Middle East was hitting living standards worldwide and required urgent de-escalation.

The article delves into the strategic importance of the Strait of Hormuz, a narrow waterway that serves as a critical conduit for global oil shipments. It highlights the geopolitical rivalry among regional powers and external actors seeking to influence or dominate traffic through the passage. By assessing the security dynamics and diplomatic maneuvers surrounding the strait, the analysis underscores how control over this chokepoint can impact both regional stability and international energy markets.

The United States has implemented a naval blockade on Iran, aiming to pressure Tehran into accepting its terms for an end to their war. The blockade, which took effect at 14:00 GMT on Monday, has been met with resistance from Iran's armed forces, who have labeled it 'an illegal act' that 'amounts to piracy.'The blockade's impact on Iran's economy is expected to be significant, particularly on its oil exports. Iran primarily exports oil and gas through its ports, with the Strait of Hormuz being the only waterway out of the Gulf. The strait is crucial for global trade, with 20 percent of the world's oil and gas supplies passing through it in peacetime.Despite the war, Iran's oil exports through the Strait of Hormuz had increased in March and early April, with the country exporting 1.84 million barrels per day (bpd) of crude oil in March and 1.71 million bpd so far in April. However, with the US blockade in place, Tehran's capacity to export crude oil has been directly hit.Iran's oil revenue has been substantial, with the country earning $4.97bn over the past month from oil exports, a 40 percent increase from before the war. However, analysts warn that the blockade will hurt Iran's economy, with Mohamad Elmasry stating that 'Iran would not be able to export oil, at least not at the same level.'The blockade will not only impact oil exports but also trade of other goods. Iran's non-oil trade reached $94bn from March 21, 2025, to January 20, with imports outpacing exports. The current blockade will hurt Iran's overall trade and economy, analysts say.Iran and China have developed a railway line to reduce dependency on straits like the Strait of Hormuz. The China-Iran railway 'helps mitigate the risks of naval interdiction by Western forces that hamper Iranian trade, particularly the transport of crude oil by Tehran's so-called 'ghost ships'.'The situation is volatile, with Frederic Schneider stating that 'it's very difficult to say how serious the US is about this blockade, how long it will last, how it will end and what is coming next.' The involvement of China, a major buyer of Iranian oil, adds an X factor to the situation.

On Tuesday, shipping data from LSEG and Kpler confirmed that at least three tankers entered the Gulf via the Strait of Hormuz, including the Panama‑flagged Peace Gulf, which is bound for Hamriyah port in the United Arab Emirates. Earlier that day, two U.S.–sanctioned vessels, the Rich Starry and the Elpis, also transited the waterway. Because none of these ships were destined for Iranian ports, they remain exempt from the U.S. blockade that began on Monday. The U.S. Central Command (CENTCOM) announced that, as of 10 a.m. ET (14:00 GMT) on Monday, a naval blockade was in effect against all maritime traffic to and from Iranian ports, in line with the presidential order issued by former President Trump. The directive applies to "vessels of all nations" operating in Iranian coastal waters, including the Arabian Gulf and the Gulf of Oman. Tehran has warned of possible retaliation against ports in neighboring Gulf states. In response to the blockade, the Islamic Revolutionary Guard Corps (IRGC) ordered every ship to follow a newly‑drawn navigation map that forces vessels to enter the strait north of Larak Island and exit south of it, citing the risk of anti‑ship mines in the former main traffic zone. Before the conflict, the strait functioned like a divided highway with two dedicated lanes—each about 3.2 km long—carrying roughly one‑fifth of the world’s oil and gas shipments. The IRGC now classifies the original lanes as "restricted" and has effectively closed them. Ship traffic has collapsed by **more than 95 %** since the war began. Kpler’s tracking data shows that only **279 vessels** passed through the strait between Feb. 28 and Apr. 12, a stark contrast to the pre‑war average of around **100 ships per day**. Even after a cease‑fire took effect on Apr. 8, a mere **45 ships** have entered or exited the waterway. The disruption has left hundreds of tankers and other vessels stranded in the Gulf, slashing global oil and gas supplies by an estimated **20 %**—the largest fuel‑supply shock on record. Damage to Gulf energy infrastructure and the sharp reduction in shipments have pushed crude prices up by roughly **50 %**, with Asian importers bearing the brunt of the price spike. According to the same Kpler data, **22 ships** have been attacked in the Strait of Hormuz since the conflict started. The incidents are distributed as follows: eight in United Arab Emirates waters, six in Omani waters, two each in Iraqi and Qatari waters, and one each in Bahraini, Kuwaiti, Saudi and Iranian waters. These figures underscore the strategic vulnerability of the world’s most critical energy chokepoint and highlight how the combined effect of the U.S. naval blockade and Iran’s alternate routing has reshaped global shipping patterns and commodity markets.

The US military's Central Command (CENTCOM) reported that no ships 'made it past' the blockade in the Strait of Hormuz during its first 24 hours. Six merchant ships were ordered to turn around after being intercepted. The blockade, which began after failed US-Iran talks in Pakistan, applies only to vessels entering and exiting Iranian ports, while others remain free to transit the waterway.CENTCOM stated that 10,000 US sailors, Marines, and airmen are involved in the operation, along with more than a dozen US warships and dozens of aircraft. The blockade's effectiveness has raised concerns about Iranian retaliation and its impact on global oil markets.Despite CENTCOM's report, there are conflicting accounts of ships transiting the strait. Reuters reported at least three vessels, including two US-sanctioned tankers, passed through without heading to Iranian ports. However, AFP and US media outlets reported two ships left Iranian ports and transited the waterway.The situation remains tense, with Iran condemning the blockade as 'piracy' and Trump threatening to 'eliminate' any Iranian ships that attempt to break the blockade. Both sides have signaled openness to further talks, with Trump suggesting potential developments within two days and Iran expressing willingness to negotiate on issues like the Strait of Hormuz, Iran's nuclear program, and a ceasefire extension to Lebanon.

Sergey Lavrov touched down in Beijing as Washington intensified its pressure on Iran by attempting to block the Strait of Hormuz, a waterway that carries roughly one‑third of China’s oil imports. The Russian foreign minister was greeted with a red‑carpet reception, according to photos released by Russia’s Ministry of Foreign Affairs. Both Beijing and Moscow condemned the United States and Israel over their involvement in the ongoing war on Iran, noting that the conflict has already strained China’s energy supplies. China, a major purchaser of Iranian crude, denounced a newly announced U.S. plan to prohibit vessels from entering or leaving Iranian ports and coastal waters, calling the measure an unjustified interference with international trade. “The Strait of Hormuz is a vital international trade route for goods and energy, and its security and uninterrupted flow serve the common interest of the global community,” Chinese MFA spokesman Guo Jiakun said on Monday. According to Al Jazeera’s Alan Fisher, the U.S. hopes that by choking Iran’s trade it can force China to pressure Tehran into returning to negotiations, given that Beijing imports about a third of its oil from Iran. Lavrov also held a telephone conversation with Iranian Foreign Minister Abbas Araghchi, emphasizing the need to prevent any resurgence of hostilities in the Middle East and reiterating Russia’s “unwavering readiness” to assist in a diplomatic settlement. Araghchi relayed details of recent U.S.–Iran talks in Pakistan, which ended without a breakthrough, underscoring the limited diplomatic progress on the issue. The visit comes as China‑Russia relations have deepened since Russia’s full‑scale invasion of Ukraine in 2022. Earlier in the week, Chinese Foreign Minister Wang Yi spoke with Lavrov, agreeing that the two capitals would cooperate to de‑escalate tensions in the region. Beijing’s diplomatic calendar this week also featured meetings with Spanish Prime Minister Pedro Sanchez, United Arab Emirates President Mohamed bin Zayed Al Nahyan, and an upcoming visit by Vietnamese President To Lam, highlighting China’s active role in global diplomacy despite its low‑profile stance on the Iran conflict. Analysts note that China’s restrained approach allows it to position itself as a “reliable, stable and predictable partner” for states seeking alternatives to U.S. influence, especially given its extensive trade ties with Tehran. Former U.S. President Donald Trump, slated to visit Beijing next month, warned he would impose a 50 percent tariff on Chinese goods if China provides military assistance to Iran. The claim followed a CNN report citing U.S. intelligence that China might deliver new air‑defence systems to Tehran. Chinese officials dismissed the report as “completely fabricated” and warned of “resolute counter‑measures” should the United States use it as a pretext for additional tariffs.

The Food and Agriculture Organization (FAO) has issued a stark warning: if the Strait of Hormuz remains blocked by the ongoing US‑Israel conflict with Iran, the world could face a food ‘catastrophe’. The disruption is already halting shipments of vital agricultural inputs, a situation that could quickly cascade into higher food prices. FAO chief economist Maximo Torero told Al Jazeera that, for now, food prices have stayed stable because existing stockpiles are absorbing the shock. However, he cautioned that this buffer is temporary and that “the clock is ticking.” FAO agrifood economics director David Laborde added that if traffic does not resume, the resulting strain on energy and fertilizer markets will translate into “higher commodity and retail prices later this year and into 2027.” According to the FAO, 20‑45% of key agrifood inputs—including fertilizers, pesticides and feed—depend on maritime passage through the Hormuz chokepoint. Nearly half of the world’s traded urea, the most widely used fertilizer, also moves through the strait, making global agriculture highly vulnerable. Recent gas supply disruptions have already forced fertilizer plants in the Gulf and beyond to cut or halt production, raising concerns that farmers may have to reduce fertilizer use or face higher production costs. Torero emphasized that poorer countries are especially at risk because planting calendars leave little room for delays; a slowdown in input delivery could quickly lead to “lower output, higher inflation and slower global growth.” The blockade stems from Iran’s decision to bring traffic to a near‑total halt in retaliation for attacks by the United States and Israel, which launched a war on Tehran on 28 February, resulting in the death of Supreme Leader Ayatollah Ali Khamenei. The conflict has already doubled oil and gas prices compared with pre‑war levels. Negotiations between Iranian and US representatives over a 21‑hour marathon failed to secure a permanent ceasefire. Subsequently, US President Donald Trump announced a naval blockade, stating that the navy would interdict ships in international waters that had paid Iran a toll to traverse the strait. The US military later declared it would block all maritime traffic entering and exiting Iranian ports, including those in the Gulf and the Gulf of Oman. FAO officials stress that decisive action—both a sustained ceasefire and the reopening of the waterway—is essential to prevent the looming food crisis from becoming a full‑blown catastrophe.

The United Nations has issued a clear appeal urging all parties to respect and maintain safe navigation through the Strait of Hormuz. The statement underscores the strategic importance of the narrow waterway for international shipping and calls for cooperation to prevent disruptions.

UK Chancellor Rachel Reeves has strongly criticized the US decision to engage in a war with Iran without a clear exit strategy, labeling it a 'folly' that has significant economic implications for the UK and the world. In an interview with the Mirror before her trip to Washington for the International Monetary Fund spring meeting, Reeves expressed her frustration and anger over the US's approach to the conflict. She emphasized that the war was not initiated by the UK and that the US's lack of a clear plan has led to the blockade of the Strait of Hormuz, a critical waterway for Iranian oil shipments. Reeves stated, 'This is a war that we did not start. It was a war that we did not want. I feel very frustrated and angry that the US went into this war without a clear exit plan, without a clear idea of what they were trying to achieve.' She added that the conflict's impact is being felt globally, including in the UK, and that it was sensible for the UK to avoid involvement. The criticism comes after a tumultuous period marked by the collapse of peace talks between the US and Iran in Islamabad and the official start of a US blockade on Iranian ports. The situation has contributed to rising oil prices and threatens to increase inflation worldwide. The IMF has released new forecasts indicating that the UK will experience the biggest economic impact among G7 countries, with GDP growth revised down to 0.8% from 1.3%. Reeves has pledged to support households with energy bills if they rise and is under pressure to reconsider a planned fuel duty increase. Prime Minister Keir Starmer has established a committee to discuss the war's impact on Britain, which met for the first time on Friday. He will also attend an international summit in Paris to address safeguarding shipping through the Strait of Hormuz.
