One year ago, US President Donald Trump introduced a 10% global tariff, sparking a trade war with far-reaching consequences. The immediate impact was severe, with the stock market experiencing its worst drop since the pandemic. In response, countries scrambled to negotiate deals with Washington or retaliate with their own tariffs. Recently, the Supreme Court ruled that most of Trump's tariffs are illegal, citing the president's lack of authority to impose broad, open-ended tariffs under a national emergency. However, this ruling did not end the trade war. Within hours, Trump invoked a different statute to launch a temporary tariff, set to expire in July. The effects of the tariffs have already reshaped the US economy. The average effective US tariff rate surged from 2.6% to over 13%, the highest level since World War II. This significant increase has led to higher costs for American consumers. According to the Tax Foundation, US households paid $1,000 more in 2025 for the same goods. Tarrifs work by imposing a tax on foreign goods and services, making them more expensive and encouraging local purchases. Despite Trump's promise that tariffs would reduce the trade deficit and make the US richer, the reality is that the average US consumer is worse off. The Penn Wharton Budget Model reports that the US collected over $287.1 billion in customs duties in 2025 and $64.4 billion in 2026. Economists at the Federal Reserve Bank of New York found that nearly 90% of the economic burden from tariffs has fallen on US businesses and consumers, with foreign exporters absorbing only a small percentage of the cost. Lower-income households have been disproportionately affected, as they spend a higher proportion of their earnings on essential goods like food, clothing, and transportation. Following the Supreme Court's ruling, the government may be required to refund up to $175 billion to businesses that paid the tariffs. With Trump's tariffs being replaced by a flat 10% tariff, the Tax Foundation projects that the average cost to US households will fall to about $600. While an improvement, it remains a significant cost for consumers.

The ongoing closure of the Strait of Hormuz, a crucial oil and gas shipping route blocked by Iran since the US-Israeli attacks began, is having ripple effects around the world. If the strait remains closed, transport blockages across the Middle East could cause significant shocks to food and medicine supplies in the UK.UK Foreign Secretary Yvette Cooper is hosting a meeting with 35 other countries to discuss reopening the strait. Experts warn that a prolonged closure could lead to food price inflation doubling in England and medicine shortages due to disrupted supply chains.Impact on Food SuppliesProf Tim Lang from City St George's, University of London, warns that 'all bets are off' for food supplies if the crisis continues. Rising fossil fuel prices will impact food transportation and production, as fuel is used to transport food and produce fertilizers and other inputs.The farming sector is already facing problems, with dairy production hit due to delayed fertilizer purchases and salad vegetable and dairy producers facing disruptions. Iranian imports like pistachios and saffron are also affected.Impact on Medicine SuppliesWhile there's no hard evidence of medicine shortages yet, price increases are being seen, which can signal disruptions in the medicine supply chain. Iran does not manufacture many medicines but affects the sector through rising energy costs and transport links between major pharmaceutical-producing countries and the UK.David Weeks from Moody's notes that shortages are driven by delays in petrochemical precursors for active pharmaceutical ingredients. Medicine stockpiles in European countries, including the UK, can last up to six months, but long-term conflicts could lead to more severe shortages.

A virtual gathering of over 40 countries will set the agenda for a global military planning meeting next week, focusing on clearing sea mines and rescuing vessels immobilised in the Strait of Hormuz.UK Foreign Secretary Yvette Cooper opened the summit by condemning what she described as “Iranian recklessness” that endangers global economic security and threatens the flow of vital energy supplies.The discussions are proceeding without direct US involvement; instead, the UK, France, Germany, Australia and several Gulf states are exploring practical steps to restore access to the strategic waterway.President Donald Trump has urged nations that depend on the strait to “build up some delayed courage” and “just grab it,” a comment that has drawn criticism from UK officials.The strait transports 10‑25% of the world’s oil and gas. Prime Minister Keir Starmer warned that reopening the lane “will not be easy,” given the scale of the disruption.Cooper outlined a multi‑pronged approach: diplomatic and economic pressure, reassurance for industry, insurers and energy markets, and coordinated actions to guarantee the safety of trapped ships and seafarers.She cited more than 25 Iranian attacks on vessels, estimating around 20,000 seafarers on roughly 2,000 ships are currently stranded.Highlighting the broader stakes, Cooper referenced World Bank projections that a prolonged blockage could push 9 million people into food insecurity and trigger unsustainable spikes in oil and food prices worldwide.At a follow‑up session scheduled for Tuesday, military planners will consider how to marshal collective defensive capabilities, including the removal of mines that Tehran may have laid to sink ships.The meeting will be hosted by Britain’s Permanent Joint Headquarters in Northwood, London, with many international leaders joining virtually.Conservative leader Kemi Badenoch warned President Trump not to abandon “a mess he’s made” in the Middle East, echoing former US Secretary of State Colin Powell’s dictum, “if you break it, you own it.”Reform UK’s Nigel Farage said he was not “angry” with Trump for entering the conflict but found the president’s press briefings “difficult to interpret.”Liberal Democrat leader Ed Davey urged Prime Minister Starmer to “step up” plans and present a clear alternative for reopening the oil‑ and gas‑laden shipping route.

Scientists are preparing to establish 4,500 native trees on the fringes of the Brecon Beacons National Park using a novel fertiliser derived from human urine.The fertiliser was produced by Bristol‑based startup NPK Recovery, which linked its mobile processing unit to the toilets serving roughly 700 revellers at the Boomtown festival in Hampshire last July.During the 2025 event the system generated 540 litres of nutrient‑rich liquid, now earmarked for planting beech, Scots pine and other native species in Wales.The three‑year restoration scheme, funded by a Forestry Commission grant, will also incorporate urine collected from additional events, expanding the supply chain for the circular fertiliser.To launch the initiative, a Scots pine seedling was planted on Thursday morning, symbolising the start of what could become a lasting Welsh forest.Lucy Bell‑Reeves, co‑founder of NPK Recovery, noted that field trials have shown the urine‑based product to be as effective as conventional fertilisers, marking its first application on trees.“Using a waste product to grow trees is a circular solution that can revitalise our struggling native species,” Bell‑Reeves said, adding that “we need to stop flushing crop and tree‑growing nutrients down the loo and start using them to increase our fertiliser security.”The company previously processed 1,000 litres of urine collected from women’s urinals at the London Marathon, converting it into an odour‑free liquid using specialised bacteria that recover nitrogen and other nutrients.NPK Recovery’s mobile laboratory enables on‑site conversion, eliminating the need for transport and preserving nutrient integrity.Partnering with the charity Stump Up For Trees, co‑founded by author‑cyclist Rob Penn, the project builds on the charity’s five‑year effort that has already planted over 500,000 trees in the region, half of its one‑million‑tree target.Penn expressed enthusiasm, stating, “This groundbreaking project has implications for the future of sustainable forestry, and collaboration with NPK Recovery brings much‑needed innovation to the sector.”

Britain is confronting the most severe energy shock since the early 1970s, as exports of oil, gas and fertiliser from the Middle East have abruptly stopped. The government says a response plan exists, but details remain vague. It is unclear whether the UK is better prepared for the fallout from Donald Trump’s war with Iran than it was for the pandemic six years ago. Ministers are sending a "we have your back" message to the public while simultaneously signalling to financial markets that any assistance will be limited and targeted. Contingency planning is especially difficult when dealing with an unpredictable leader like Trump. Britain’s heavy reliance on imported energy and food means that reassurance can only hold for a short time. The economy entered the conflict already on shaky ground: unemployment rose steadily throughout 2025 and growth stalled to a virtual standstill in the final quarter of that year. The sudden loss of Middle‑East energy and fertiliser supplies now adds a colossal supply shock. Last year, Trump’s “liberation day” tariff hikes served as a dry run for a far more serious confrontation. This time, the war is taking place in a region that is both volatile and crucial to the global economy. In the past two weeks, the repercussions have been felt across Asia – the Philippines declared a state of emergency, Sri Lanka introduced a four‑day work week, and South Korea announced budget measures to help households cope with soaring energy bills. The continent is the most dependent on Gulf‑exported energy, making the impact there the sharpest. The International Monetary Fund warned that the shock will drive higher prices and slower growth worldwide. Shortages push fuel and food prices up, eroding disposable income, prompting businesses to cut staff, and increasing the risk of recession. The UK, already projected to be one of the poorest‑performing major economies in 2026, could see its fresh graduate cohort face a brutal job market. Trump’s claim that the war could end within two or three weeks appears desperate. Even a rapid cease‑fire would leave substantial collateral damage, creating a stagflation scenario that could hurt Republican prospects in the upcoming mid‑term elections. British officials hope a swift resolution will limit economic damage, allowing a short‑term inflation spike to subside and the Bank of England to resume interest‑rate cuts. Treasury plans include scrapping the planned autumn fuel‑duty rise and providing targeted help for the poorest households, though the path is unlikely to be that simple. Currently, the Treasury is hesitant to act boldly for fear of unsettling bond markets. History – the 2008 banking collapse and the 2020 pandemic – shows that governments can act decisively without triggering a market backlash, using tools such as aggressive rate cuts, increased borrowing, and quantitative easing. The Bank of England has warned of a "substantial negative supply shock" and is expected to soften markets for future rate cuts, which are inevitable. Finance Minister Rachel Reeves could mitigate labour‑market pain by reversing recent increases in employers’ National Insurance contributions, subsidising public transport, and even lowering speed limits to conserve energy. The war, like the pandemic and Russia’s invasion of Ukraine, underscores the fragility of global supply chains and the need for greater British self‑reliance. Investing heavily in renewable energy is essential, but the UK also imports roughly 40% of its food and has not run a manufacturing trade surplus since 1982. In a world of disrupted supply lines, a robust plan for economic self‑sufficiency is more urgent than ever. Larry Elliott is a Guardian columnist.

The United States is expanding its military footprint in the Gulf as the US‑Israel war with Iran enters its second month. Since the Feb. 28 launch of Operation Epic Fury, a joint air campaign targeting Iranian military and nuclear sites, more than four weeks of strikes have resulted in thousands of casualties.Defense Secretary Pete Hegseth announced the deployment of a third aircraft carrier, the USS George HW Bush, joining the USS Abraham Lincoln, which is currently conducting daily combat sorties from the Arabian Sea, and the USS Gerald Ford, now under maintenance in Croatia.These carrier groups carry thousands of sailors, Marines and specialised support personnel, forming the core of the US’s power projection in the region.Carrier Strike Group (CSG) refers to an aircraft carrier plus its escort ships and support units that together function as a floating base. A typical CSG includes:An aircraft carrier60‑75 fighter jets and helicopters2‑4 Arleigh Burke‑class destroyersA guided‑missile cruiserA submarine for underwater protectionSupply shipsAs of April 1, the USS Abraham Lincoln remains the only carrier launching daily combat missions against Iranian targets, while the USS George HW Bush is en route and expected to eventually replace the Gerald Ford in the Mediterranean.Amphibious Ready Group (ARG) operates as a mini‑carrier, carrying US Marines and equipment for sea‑to‑land invasions. The USS Tripoli ARG arrived in the Middle East on March 27, and the USS Boxer ARG is expected to join the theater by mid‑April. An ARG typically comprises:Three specialised ships~2,200 Marines (a Marine Expeditionary Unit)Short‑takeoff aircraftLanding craft for beach assaultsThe key distinction: ARGs are built to land troops on shore, whereas CSGs are designed to project air power and conduct major naval warfare.A Marine Expeditionary Unit (MEU) is a rapid‑response, self‑contained force of 2,200‑2,500 Marine Corps personnel capable of combat and humanitarian missions. On Friday, US Central Command confirmed that 2,200 Marines from the 31st MEU arrived in Middle Eastern waters after departing Sasebo, Japan, on March 13. A second unit, the 11th MEU with roughly 2,500 Marines, is inbound after leaving San Diego on March 18.The Pentagon has also ordered about 2,000 soldiers from the 82nd Airborne Division to move to the region, adding to the approximately 50,000 US troops already stationed in the Middle East.An MEU is organized into four elements:Command Element – ~200 personnel for planning and command‑and‑control.Ground Combat Element – ~1,200 troops centered on an infantry battalion with artillery and armoured vehicles.Aviation Combat Element – ~500 personnel operating transport helicopters, attack aircraft and Osprey tilt‑rotors.Logistics Combat Element – ~300 personnel providing up to 15 days of self‑sustainment, including medical, engineering and maintenance support.MEUs are typically deployed aboard a three‑ship ARG, which serves as a floating base. The ships include:Landing Helicopter Assault/Dock – a small carrier carrying short‑takeoff aircraft such as F‑35Bs and attack helicopters.Amphibious Transport Dock – a mid‑size vessel transporting troops and heavy vehicles.Dock Landing Ship – primarily for cargo and heavy equipment.MEUs can execute sea‑to‑land assaults, raids, evacuations, humanitarian aid and disaster‑relief operations, and they are often the first forces on the ground in emerging conflicts.The US Marine Corps maintains seven active MEUs; the 31st (Asia‑Pacific) and 11th (West Coast) are currently assigned to the Iran war. The other units are distributed as follows:East Coast: 22nd, 24th, 26th MEUWest Coast: 11th, 13th, 15th MEUAsia‑Pacific: 31st MEUTypically, three MEUs are forward‑positioned at any time, rotating through deployments in the Mediterranean, Gulf and Asia‑Pacific regions.Historically, MEUs have played pivotal roles in US operations: during the 2001 Afghanistan invasion, the 15th and 26th MEUs conducted one of the longest amphibious vertical insertions; in 2003‑2004 they helped secure Iraqi ports and fought in Fallujah; and in 2024 they provided sea‑based support for the attempted abduction of Venezuelan President Nicolás Maduro.

Russia has pledged to continue providing assistance to Cuba, following the delivery of a Russian-flagged tanker carrying 730,000 barrels of oil to the island nation. This shipment marks the first crude oil delivery to Cuba in three months, providing much-needed relief to the country's struggling energy grid.Maria Zakharova, spokesperson for the Russian Ministry of Foreign Affairs, stated that Cuba is Russia's closest friend and partner in the Caribbean, and that Russia will not abandon it. Zakharova also expressed solidarity with Cuba, calling for the US to lift its blockade on the independent sovereign state.The oil shipment, which arrived at the Bay of Matanzas, is expected to produce approximately 180,000 barrels of diesel, enough to meet Cuba's daily demand for nine or 10 days. This temporary reprieve comes as Cuba faces an energy crisis, exacerbated by the loss of Venezuelan oil supplies following the removal of President Nicolas Maduro in January.The energy crisis has led to frequent blackouts and brought hospitals, public transportation, and farm production to the brink of collapse. The Cuban government has welcomed the shipment, with Energy and Mines Minister Vicente de la O Levy expressing gratitude to Russia for its support.Russia's actions have drawn attention from the US, with President Donald Trump stating that he had 'no problem' with Russia sending oil to Cuba for humanitarian reasons. However, Trump also criticized Cuba's leadership, saying that the island nation's problems would not be solved by receiving oil shipments.

President Donald Trump told allies that Tehran does not need to negotiate a settlement for the hostilities to cease, estimating the conflict could be over in two to three weeks. Iranian Foreign Minister Abbas Araghchi, however, dismissed any hope of talks, stating that Tehran has zero trust in Washington.US‑Israeli air raids persist across Iran, hitting key industrial and civilian targets such as steel factories in Isfahan and Farokhshahr, pharmaceutical facilities, port infrastructure, meteorological stations and a residential complex. Iranian state media and the Red Crescent reported explosions in cities including Ahvaz, Shiraz, Isfahan, Karaj, Kermanshah and Bandar Abbas.An Iranian official said the Tofigh Daru pharmaceutical raw‑material plant in Tehran was struck, crippling its research and development wing and delivering a "blow to the national medical supply chain." In Bandar Abbas, the Shahid Haqqani passenger pier was bombed, though officials claimed no casualties.A desalination plant on Qeshm Island, crucial for water supply in the Strait of Hormuz, was knocked out of service by the strikes.Analyst Trita Parsi warned that the war is unlikely to end swiftly and that the Strait of Hormuz will remain closed, noting that it will not be easy for President Trump to simply walk away from the conflict.Casualties have surpassed 2,000 Iranians, with numerous civilian sites—including hospitals, schools, universities and pharmaceutical factories—targeted, raising concerns of potential war‑crime violations.On the diplomatic front, Spain, France and Italy have begun curbing U.S. military operations by closing airspace, denying base access and limiting logistical support. Meanwhile, China and Pakistan have tabled a five‑point cease‑fire proposal that calls for reopening the Strait of Hormuz.Regional leaders are also active: Qatar’s Emir Sheikh Tamim bin Hamad Al Thani and UAE President Sheikh Mohamed bin Zayed Al Nahyan have convened to discuss the Iran war, while Argentina, under President Javier Milei, officially labeled Iran’s Islamic Revolutionary Guard Corps as a “terrorist” organization.Pope Francis (Leo XIV) appealed directly to President Trump, urging an end to the violence and expressing hope that the U.S. leader is moving toward a resolution.In the Gulf, Iranian drones have repeatedly struck Kuwait’s airport, forcing the closure of its airspace since late February; Saudi Arabia has stepped in to provide transport for affected passengers. Bahrain sounded air‑raid sirens, and Saudi forces reported intercepting two additional drones.A merchant vessel north of Doha suffered damage from an "unknown projectile," though the crew remained unharmed and no environmental harm was recorded.U.S. officials remain divided: while Trump predicts a rapid end, Defense Secretary Pete Hegseth warned that the United States is "negotiating with bombs" and that the coming days are decisive. The war’s uncertainty has pushed oil prices higher, prompting U.S. Senator Chris Coons to warn that American families face rising grocery, utility and mortgage costs.Israel continues to face coordinated attacks from Iran and Hezbollah, with missile and drone incursions reported across northern and central regions. Despite these threats, Prime Minister Benjamin Netanyahu asserted that Iran’s regional allies no longer pose an "existential threat," yet Israel plans to maintain its offensive, including operations in Lebanon.In Lebanon, Israeli ground advances and heavy bombardments have resulted in over 1,200 deaths and displaced roughly 1.2 million people since early March. Iraqi militia Kata’ib Sayyid al‑Shuhada warned that any U.S. ground incursion into Iran via Kuwait could trigger an all‑out war.

Cuba's tourism industry, once a pillar of the country's economy, is reeling from the effects of the US oil blockade imposed in January. The blockade has led to a significant decline in visitors, with only 1.6 million tourists visiting the island from January to November last year, a drop from its 2018 peak of 4.8 million.The decline in tourism has had a devastating impact on the livelihoods of Cubans who rely on the industry for their income. Taxi driver Rainier Hernandez, 38, used to work upwards of six hours a day ferrying tourists around Havana, but now he is lucky to get one or two hours of paid work in a day.The economic momentum has sputtered in recent years, a trend accelerated by a recent spike in tensions between the US and Cuba. The blockade has pushed petrol prices up to $12 per litre ($45.36 per gallon) and led the government to cancel nearly all public transport options.Tour guides like Carlos Fariñas, 29, are struggling to make ends meet, with some considering leaving the island in search of better opportunities. 'If there is no tourism, there is no economy,' Fariñas said.The situation has become so dire that some Cubans are worried about losing their homes, as the collapse of the tourism industry could cost them the very roof over their heads. 'I would die of hunger' if I had to wait for tourists to return, said Alejandro Ricardo, 26, who manages an Airbnb in Havana.The US oil blockade has had far-reaching consequences for Cuba's economy, with the country's tourism industry accounting for nearly 12 percent of its GDP at its height in the late 2010s. The blockade has left many Cubans uncertain about their future on the island, as they struggle to afford necessities.
