The recent developments in the conflict between the US and Iran have left global markets reeling. President Donald Trump's threat to attack Iran's civilian power infrastructure led to a surge in oil prices, a plummet in stock futures, and a climb in bond yields. However, the president quickly walked back his statement, announcing that talks with Iran were going well. This move, dubbed 'Taco' (Trump Always Chickens Out), was first seen during the tariffs crisis last year. The immediate market reaction was significant, with bonds and stocks recovering rapidly after Trump's statement. The S&P; 500 stock index jumped 1.5% by 9:30 am in New York, defying earlier futures contracts that signaled a 1% daily decline. However, Iran's response has shown that Trump's tactic may be losing steam. Iranian officials denied the 'productive conversations' Trump claimed had taken place, and launched missile attacks on Israel, Iraq, and other American allies in the Gulf. This has led to renewed market volatility, with oil prices rebounding and stocks giving up their gains. The article suggests that Trump no longer has control of events in Iran and that the conflict's outcome will likely be decided by Tehran. The Iranian regime has little incentive to back down, having already suffered significant losses but still capable of imposing enormous costs on the world by throttling the Strait of Hormuz and depriving the global economy of 12.5 million barrels of oil and 11.5 billion cubic feet of gas per day. As markets continue to react to the situation, it appears that Trump's 'Persian Tacos' may not be enough to calm investor nerves. The S&P; index lost 1.78% on Thursday, closing at a new low for the year, and the price of Brent crude hovered around $108.

Saudi Arabia has urged the US to ramp up attacks on Iran, a Saudi intelligence source has confirmed, while it is weighing a decision on whether to join the fight directly. The Saudi source confirmed reporting that the kingdom’s de facto leader, Crown Prince Mohammed bin Salman, has urged Donald Trump not to cut short his war against Iran, and that the US-Israeli campaign represented a “historic opportunity” to remake the Middle East.The intelligence source said Riyadh was not just calling for the military campaign to be continued, but to be intensified. Trump appeared to confirm the report about the crown prince’s role, telling journalists on Tuesday: “Yeah, he’s a warrior. He’s fighting with us.”There are no reports of active Saudi military involvement in the nearly four-week-old war so far, but a Saudi political analyst said the kingdom was likely to take that step if current peace efforts led by Pakistan failed.“What matters now is Iran’s decision,” Mohammed Alhamed, a Saudi geopolitical analyst, said. “If Iran engages seriously, there is still a path to contain escalation. If it rejects the conditions and continues its attacks, the threshold for Saudi action will be crossed.”Alhamed added that Saudi Arabia “is not reacting impulsively”.“It is calibrating its response and preparing for a scenario where escalation, if it happens, will be deliberate and decisive,” he said, adding that Saudi Arabia “has not been pushing for war.”“It has been trying to avoid being drawn into it, while keeping all options on the table,” he said.Saudi Arabia has come under Iranian drone attack, as part of Tehran’s response to the US-Israeli attack on 28 February. One drone strike a week ago hit an oil refinery in Yanbu on Saudi Red Sea coast.The attack on Yanbu signalled an Iranian warning that it could also threaten that economic lifeline.“I believe that Saudi Arabia still maintains cautious neutrality in the Iran-Israel-US war,” Hesham Alghannam, a Saudi defence expert told Agence France-Presse. But he added: “If the Houthis strike Saudi assets, Riyadh may shift toward defensive coalition support or limited retaliation.”The crown prince solidified his hold on power by cultivating a close relationship with Trump, but will now have to rethink Saudi reliance on the US for its security, observers have argued.“MBS [Mohammed bin Salman] has lost the bet on all his investments over the last several years,” Ellie Geranmayeh, senior policy fellow at the European Council on Foreign Relations said. “He financially invested in Trump and Trump’s family and his corporation and his White House, but at the end of the day the views of the Saudis and of the whole Gulf have been sidelined by the wishes of Benjamin Netanyahu.”

The US Environmental Protection Agency (EPA) has announced a temporary waiver allowing the sale of a higher-ethanol fuel blend, known as E15, in an effort to alleviate soaring gas prices that have been exacerbated by the ongoing Iran war.E15, which contains a higher percentage of ethanol than standard gasoline, has been prohibited during warm weather months due to concerns over its potential to worsen smog. However, the EPA's decision, supported by the US agriculture secretary, Brooke Rollins, aims to provide relief to consumers at the pump.“President Trump is unleashing American Energy Dominance, and today’s action will directly lower prices at the pump and gives a clear demand signal to our domestic biofuels producers,” Rollins stated.The summer waiver for E15 has become a recurring measure in recent years, with both Republicans and Democrats advocating for its permanent implementation to reduce fuel costs. Currently, E15 is already permitted in several states, including Iowa, Illinois, Minnesota, Nebraska, Missouri, Wisconsin, and most of South Dakota.However, not all experts are convinced that the move will significantly lower gas prices. Kenneth Gillingham, a professor at the Yale School of the Environment, pointed out that E15 is not widely available in all states, and some areas lack the necessary infrastructure or sufficient ethanol supply to support increased use.Gillingham also highlighted potential risks associated with E15, particularly for older vehicles, boats, and all-terrain vehicles, due to its higher corrosive ethanol content. Additionally, increased corn usage for ethanol production could lead to higher costs for animal feed and, subsequently, grocery prices.“I think it’s difficult to see when the ledger’s settled how this is a benefit for US consumers,” said Jason Hill, a professor at the University of Minnesota.The decision has also drawn criticism over its potential environmental impacts, with concerns about increased ozone issues, respiratory problems, and even premature deaths.While the oil industry has generally opposed the expansion of E15, citing costly biofuel blending and potential price increases, the American Petroleum Institute has expressed support for the temporary waiver, emphasizing its role in ensuring affordable and reliable energy for American consumers.

US markets witnessed a significant downturn on Thursday, marking their biggest slump since the onset of the US-Israel war with Iran. The Dow closed 450 points down, while the S&P 500 dipped 1.7%. The tech-heavy Nasdaq fell 2.3%, plunging into correction territory, which occurs when an index falls at least 10% below its most recent peak. The conflict has led to a surge in oil prices, reaching levels not seen since Russia's invasion of Ukraine in 2022. At the end of the day on Thursday, Brent crude oil, the global benchmark, was about $107 a barrel, while US crude hit $93 a barrel. Average US gas prices at the pump reached $3.98 a gallon, according to AAA. Despite the soaring prices, Donald Trump said that oil prices “have not gone up as much as I thought” during a cabinet meeting on Thursday. He predicted that prices would “come back down to where it was, and probably lower,” and that the impact on the stock market would reverse once the conflict ends. Markets have been growing weary of Trump's mixed signals on the US's stance in negotiations with Iran. Stocks dipped on Thursday morning after Trump posted a warning to Iranian negotiators that they “better get serious, before it’s too late.” However, later in the morning, Trump said that there were “very substantial talks” happening with Iran and that the country allowed 10 oil tankers to pass the blocked strait of Hormuz. The White House announced it will extend a pause on Iranian energy infrastructure strikes by 10 days, until 6 April. A new report estimates US inflation will average 4.2% this year, compared with an average of about 2.6% in 2025, according to the Organization for Economic and Cooperation and Development (OECD). The increase in inflation reverses what was expected to be strong growth for the global economy before the conflict began.

UK Chancellor Rachel Reeves is facing pressure to raise taxes on businesses generating 'windfall' profits linked to the US-Israel war on Iran to fund emergency cost of living support for UK households.A group of leading charities, campaigners, and trade unions, including Greenpeace UK, the National Education Union, and Tax Justice UK, have written an open letter to Keir Starmer and Reeves, urging the government to strengthen its existing North Sea energy windfall tax and introduce new levies for firms in other sectors that stand to financially benefit from the conflict.The letter highlights that energy companies, banks, agricultural commodities businesses, defence companies, and tech firms are likely to profit from the economic fallout of the war. The group argues that the extra revenue generated from taxing these 'excess profits' could be used to support households struggling with the cost of living and invest in the UK's future energy security.R Reeves has signalled that the government is ready to provide targeted help for households grappling with the economic fallout from the Middle East conflict, amid a surge in energy prices since the onset of the war. The chancellor has also warned companies that she will not tolerate corporates profiteering from the crisis, telling bosses that the Competition and Markets Authority has been put on notice to detect and crack down on price gouging.The UK already has a windfall tax on North Sea oil and gas firms, the energy profits levy, which is due to run until 2030. However, Reeves had been planning to ease the tax before the US and Israel attacked Iran on 28 February.

A recent surge in no-fault evictions in the UK has left many tenants reeling, with one individual sharing their heart-wrenching experience of being forced out of their home despite being a responsible tenant.The tenant, who wishes to remain anonymous, has been served a section 21 notice ahead of the upcoming ban on no-fault evictions, which is set to come into effect soon. This has created a sense of uncertainty and anxiety, with the tenant struggling to come to terms with the fact that they will have to leave their home after years of paying rent and being a model tenant.The UK government has been criticized for delaying reform and creating the perfect conditions for this situation. By announcing changes years in advance but failing to implement them in time, the government has effectively signaled to the market to act now, leading to a last-minute rush of notices.The issue is further complicated by rising rents in London, which continue to price out tenants and limit their choices in the rental market. Without meaningful limits, the reality is that tenants are often forced to move not because they want to, but because they are priced out or pushed out.The tenant's experience highlights the painful simplicity of the reality faced by many renters in the UK. Despite doing everything right, they can still lose their homes. This raises questions about who the current reform was really designed to protect.

UK Prime Minister Keir Starmer has announced plans to address addictive features in social media platforms, signaling a potential regulatory shift following a significant US court ruling that held Meta and YouTube accountable for harms caused by their technology designs.The prime minister emphasized that the recent California court verdict reflects rising public expectations for more aggressive regulation of social media platforms. "I'm absolutely clear that we need to go further," Starmer stated, adding that "the status quo isn't good enough" in terms of protecting children online.Starmer specifically mentioned that the government is consulting about banning social media for under-16s and expressed strong commitment to addressing addictive features within social media platforms. These remarks come amid growing international pressure on tech companies to address the potential harms of their products on young users.In the landmark US case, a California jury found Meta and YouTube negligent for failing to provide adequate warnings about the potential dangers of their platforms. The plaintiff, a 20-year-old woman who claimed she became addicted to social media during her childhood, was awarded $6 million (£4.5 million) in damages, with Meta responsible for 70% of the payment and YouTube covering the remainder.The Duke and Duchess of Sussex welcomed the verdict as "a reckoning" for tech companies, stating in a joint statement: "For too long, families have paid the price for platforms built with total disregard for the children they reach." They emphasized that "today, the truth has been heard and precedent has been set" regarding children's safety versus corporate profits.Both Google, which owns YouTube, and Meta have indicated they will challenge the decision. Google claimed the case "misunderstands YouTube, which is a responsibly built streaming platform, not a social media site," while Meta stated it "respectfully disagrees with the verdict and is evaluating our legal options." The verdict came after nine days of deliberation in the first lawsuit concerning social media's alleged harm to young people to reach trial.The ruling has resonated beyond the courtroom, with European Commission digital chief Henna Virkkunen noting that such cases send "a very clear message" to online platforms about the risks they pose. Campaigners for safer social media have celebrated the decision as a potential watershed moment in regulating platforms like TikTok, Instagram, and X.The Molly Rose Foundation, established after the death of 14-year-old Molly Russell who was exposed to harmful content on Instagram, called for legislation that would make "safety and wellbeing the price for tech firms to pay for doing business in the UK." Thomas Lancaster, a computing expert at Imperial College London, emphasized that policies must be effectively enforced to protect those they're designed to safeguard.Sacha Haworth, executive director of the Tech Oversight Project, declared that "the era of big tech invincibility is over," suggesting that the verdict validates concerns about tech platforms' impact on young people that have been raised for years.

The UK's ambition in quantum computing is being backed by sustained investment in people and fundamental science, with a focus on building a strong foundation for the sector. UK Research and Innovation (UKRI) has been instrumental in supporting hundreds of academics and building the infrastructure needed for the industry to thrive.In the last 10 years, UKRI's councils have made significant investments in physics research, including support for 100 PhDs in quantum technology launched in 2024, quantum computing industrial doctorate awards, and funding 14 early-career fellows in the last 18 months.The investment is paying off, with the quantum sector showing promising growth and potential to create 100,000 jobs in the next 20 years. The government has signalled its recognition of the opportunities in quantum computing with a further £1bn procurement programme, making the UK one of the most exciting and well-supported places in the world for quantum computing researchers, companies, and students.Prof Charlotte Deane, UK Research and Innovation, highlights that the UK's advantageous position in quantum has emerged through sustained long-term public investment into fundamental physics research projects, and the best people, infrastructure, and partnerships.

The Arm AGI CPU: A New Era of In-House SiliconFor the first time in its 35-year history, Arm Holdings is stepping out from behind the licensing model to manufacture its own silicon. The company revealed the Arm AGI CPU at an event in San Francisco, a production-ready processor designed specifically for AI inference in data centers. Unlike its traditional business model of licensing designs to giants like Nvidia and Apple, Arm has developed this chip using its own Arm Neoverse family of CPU IP cores.This strategic pivot is backed by a robust ecosystem of launch partners, including Meta, which is the chip's first customer. Other key partners include OpenAI, Cerebras, and Cloudflare. The chip is already ready for order, signaling that Arm is moving aggressively to capture value in the booming AI infrastructure market.The Critical Role of CPUs in AI InfrastructureWhile GPUs have dominated headlines for training large language models, Arm is highlighting the often-overlooked importance of the central processing unit (CPU) in modern AI racks. Arm argues that the CPU is the pacing element of modern infrastructure, responsible for managing thousands of distributed tasks, including memory allocation, storage scheduling, and data movement across systems.Infrastructure Management: CPUs ensure that distributed AI systems operate efficiently at scale.Market Constraints: The demand for high-performance computing is exacerbating global supply chain issues, with Intel and AMD recently informing Chinese customers of extended wait times due to CPU shortages.Cost Implications: These supply constraints are contributing to rising prices for computer hardware.Breaking the Licensing Model: A Strategic Bet on CompetitionThe release of the Arm AGI CPU represents a historic deviation from the company's founding principles. For decades, Arm has operated as a pure-play design licensor, allowing partners to manufacture chips based on its architecture. However, the company is now poised to compete directly with many of its biggest customers.Majority-owned by the Japanese conglomerate SoftBank Group, Arm's move suggests a desire to capture more of the value chain. By building its own silicon, Arm can offer a more integrated solution for AI workloads, potentially undercutting or complementing the offerings of its licensees. This shift challenges the traditional semiconductor ecosystem and sets a precedent for other IP licensor to consider building their own hardware.The Future of Chip Architecture in the AI RaceArm's entry into manufacturing signals a new phase in the AI chip wars. As the industry moves toward specialized silicon for inference, the line between design houses and manufacturers is blurring. We can expect to see more IP licensor developing their own chips to ensure they have control over the performance and efficiency of the hardware powering the next generation of AI models.
