Japan's economic strategy has inadvertently created a Japanese century in global finance, driven by the yen's role as a cheap and reliable funding currency. The Bank of Japan's loose monetary policy has suppressed yields on public debt, effectively creating a publicly subsidized funding pipeline for bankers.By borrowing cheaply in yen and investing in higher-return assets, such as US equities, global investors have profited tens of billions of dollars from the 'yen carry trade'. This trade surged after the pandemic, with speculators betting $435bn in the two years to 2024 out of the estimated $1.7tn worth of yen supplied.Despite Japan's first rate hike since 2007 in March 2024, the carry trade remains popular. However, a persistent fear exists that the BoJ may aggressively raise rates, risking a global financial shock. A stronger yen would increase the cost of repaying yen-denominated debts, and heavily leveraged hedge funds could face significant losses.Japan's economic success has created an external dependency on the carry trade to manage internal crises. The country's reflationist prime minister, Sanae Takaichi, is committed to fiscal expansion, which may continue to stabilize the private sector but not necessarily drive growth.Economic analysis suggests that Japan's growth constraints are rooted in its macroeconomic prices, including profit, exchange rate, interest, wages, and inflation. While Japan has seen recent real wage growth, wages have historically been flat or falling, and the country's firms lack a reliably competitive exchange rate and viable profit rate to drive demand and reform.

The Accelerator's Withdrawal: A Signal of Loss of ConfidenceDelve's relationship with Y Combinator has officially ended following a series of damaging allegations regarding compliance and data security. This severance marks a significant blow to the startup's credibility, compounded by the distancing actions of other major investors like Insight Partners.The Catalyst: Anonymous Allegations and Data BreachesThe controversy stems from an anonymous Substack campaign by "DeepDelver," which accused the company of misleading clients about regulatory compliance and passing off open-source tools as proprietary technology. These claims were further fueled by a security researcher's ability to access sensitive Delve data and a malware incident involving a customer, LiteLLM.YC's Response: Delve was removed from the accelerator's portfolio directory, with COO Selin Kocalar confirming the split on X.Insight Partners: The firm initially deleted posts about its investment but later restored the primary blog entry.The Defense: A Coordinated Attack or Operational Failure?In a bid to set the record straight, Delve's leadership team, including CEO Karun Kaushik, claims the attacks are a coordinated smear campaign orchestrated by an attacker who exfiltrated internal data. They argue that the "evidence points to a malicious attack rather than a genuine whistleblower."However, the company also acknowledged "growing too fast and falling short of our own standard." To mitigate the damage, Delve has hired a cybersecurity firm, offered complimentary re-audits to customers, and clarified that their open-source usage is compliant with Apache 2.0 licensing.Future Outlook: Rebuilding Trust in a Fragile EcosystemThe departure from Y Combinator suggests that the startup's growth trajectory is now in jeopardy. For a compliance-focused company, trust is the primary currency; the current allegations threaten to devalue this currency permanently. The coming months will determine if Delve can survive this reputational crisis or if it will become a cautionary tale in the compliance tech sector.

Iran carried out the execution of Abolhassan Montazer and Vahid Baniamerian on Saturday morning, following a Supreme Court ruling that confirmed their death sentences for membership in the outlawed People’s Mojahedin Organization of Iran (PMOI/MEK) and involvement in "armed rebellion" through multiple terrorist acts. The two men were hanged after a Revolutionary Court sentenced them in late 2024, a case that underscores Tehran's intensified crackdown on dissent amid the US‑Israeli war on Iran that began on February 28. This latest execution follows the hanging of four other PMOI members—Mohammad Taghavi, Akbar Daneshvarkar, Babak Alipour and Pouya Ghobadi—on March 30‑31, bringing the total number of executed opposition figures to six since the conflict escalated. The PMOI condemned the hangings in an April 2 statement, labeling Tehran's actions a "futile" attempt to suppress opposition and warning that such brutality will only fuel the resolve of Iran’s youth to challenge the regime. Human‑rights groups have also decried the executions. Amnesty International reported that the men were allegedly tortured while in custody and transferred to an undisclosed location shortly before their deaths. The organization warned that additional protesters—some sentenced to death for participation in the January anti‑government demonstrations—could face execution after being moved from Ghezel Hesar prison. Amnesty’s deputy regional director for the Middle East and North Africa, Diana Eltahawy, said, "It is unconscionable that even as the population endures mass bereavement from aerial bombardments, the Islamic Republic continues to weaponize the death penalty to eradicate dissenting voices and terrorise its people." The wave of hangings also includes the case of Kouroush Keyvani, a dual Iranian‑Swedish national convicted of spying for Israel, whose execution sparked outrage in Stockholm and the European Union. Another individual convicted of acting on behalf of Israel and the United States during the protests was executed on Thursday. These developments occur against a backdrop of intensified military confrontations, with Iran reporting the downing of U.S. aircraft and ongoing aerial bombardments by Israel and the United States, further complicating the nation’s internal security landscape. International observers warn that the continued use of capital punishment as a tool of political repression not only violates human‑rights norms but also risks deepening regional instability as the war persists.

Defense Secretary Pete Hegseth instructed Army Chief of Staff General Randy A. George to step down with immediate effect, a move announced on X by Pentagon spokesperson Sean Parnell on Thursday. The statement said George would "retire from his position" but offered no explanation, a notable omission given the ongoing US‑Israel war against Iran.The abrupt removal adds to a string of high‑profile dismissals that have occurred since Hegseth assumed office in January. CBS first reported the decision, citing a source who said Hegseth seeks a leader who will execute his and President Donald Trump's strategic vision for the Army.Appointed in 2023 under former President Joe Biden, the 61‑year‑old General George brought extensive combat experience from Iraq and Afghanistan. During his tenure he was praised for cutting redundancies and championing new technologies such as low‑cost missile‑interceptor drones and artificial‑intelligence‑driven targeting systems.According to The New York Times, the firing may be tied to a dispute over Hegseth’s decision to block the promotion of four officers from a list of 29. While most of the blocked officers were white men, the two remaining were Black and two were women, prompting senior officers to question whether racial or gender bias influenced the action. When General George sought a meeting with Hegseth to discuss the matter, the defense secretary reportedly refused.In addition to George, Hegseth dismissed two other senior officials on Thursday: General David M. Hodne, head of the Army’s Transformation and Training Command responsible for modernization efforts, and Major General William Green Jr., the Army’s chief of chaplains. The Pentagon has not formally confirmed these removals, though the Joint Chiefs of Staff issued a tribute praising George’s decades of service.The personnel shake‑up unfolds against a broader backdrop in which US and Israeli officials have framed the Iran war as a religious undertaking. The Military Religious Freedom Foundation reported receiving complaints that senior commanders described the conflict as aiming to bring about “Armageddon” or the biblical “end times.”Earlier, in October, former Army Vice Chief of Staff General James J. Mingus retired a year ahead of schedule, with no reasons disclosed, adding to speculation about internal turbulence within the Pentagon.

The Guardian’s investigation has revealed that the company responsible for the unauthorised partial felling of a 500‑year‑old oak in Whitewebbs Park, Enfield, was Ground Control, a maintenance business that reports a turnover of £190 million. The tree was cut down in September 2025 on behalf of Mitchells & Butler Retail (MBR), the owner of the Toby Carvery restaurant chain. MBR initially defended the action, claiming its contractor warned that the oak was diseased and posed a safety risk. However, a coalition of experts – including a Forest Commission investigator and ancient‑tree specialist Russell Miller – found the tree to be healthy with no imminent danger. Miller described the alleged “hazard” as an old, semi‑occluded wound that did not justify felling the entire tree. According to Dr. Ed Pyne of the Woodland Trust, the delay in identifying the contractor highlights a broader lack of transparency: "What evidence exists that the tree was dangerous? What qualifications did the operatives have?" He added that the justification for the removal remains unsubstantiated. Ground Control’s own documentation shows the work was assigned to its grounds‑maintenance team rather than its specialist arborists, a detail that fuels further criticism of MBR’s decision‑making process. Sources close to the firm say an internal review was conducted by a contracts manager, not a tree expert. Enfield Council, which owns the park, has launched legal action to evict Toby Carvery after MBR refused to apologise or offer compensation. The council also referred the incident to the police, but officers declined to investigate, deeming it a civil matter. Complicating the dispute, MBR is majority‑owned by investment group Enic, which holds strong financial ties to Tottenham Hotspur. The football club plans to develop a women’s training academy on 17 hectares adjacent to the park, a proposal opposed by the local campaign group Guardians of Whitewebbs. The group has secured a judicial review of the planning permission, set for June. In a statement last April, MBR asserted that its “specialist arboriculture contractors” deemed the split and dead wood a serious health‑and‑safety risk. A Toby Carvery spokesperson declined further comment, citing ongoing legal proceedings. The revelation of Ground Control’s involvement adds a new layer to the controversy, raising questions about corporate responsibility, environmental stewardship, and the adequacy of legal protections for historic trees in urban green spaces.

Argentina has taken a significant step in its diplomatic relations with Iran by expelling the Iranian charge d'affaires in Buenos Aires, Mohsen Tehrani. This move comes in response to Iran's rejection of Argentina's decision to blacklist the Islamic Revolutionary Guard Corps (IRGC) as a 'terrorist' group.The Foreign Ministry of Argentina stated that Iran's response contained 'false, offensive and unfounded accusations against the Argentinian Republic and its highest authorities.' The ministry emphasized that these statements constitute unacceptable interference in Argentina's internal affairs and a deliberate misrepresentation of decisions adopted in accordance with international law and national law.Iran's Foreign Ministry had condemned Argentina's move against the IRGC, calling it an 'action against Iran's security and national interests.' Tehran accused Argentina of making this decision 'under the influence of inducements and pressures from the genocidal and occupying Zionist regime,' referring to Israel.The designation of the IRGC as a 'terrorist' group by Argentina follows similar moves by the US in 2019 and the European Union in January. Argentina's President Javier Milei, who has taken staunchly pro-Israel positions, described himself as 'the most Zionist president in the world.'The relationship between Argentina and Iran has been strained, particularly over the 1994 bombing of a Jewish centre in Buenos Aires, which an Argentinian court ruled was carried out by Iran. Iran has denied its involvement in the attack.Milei's government cited the 1994 attack in its decision to blacklist the IRGC. The Argentinian Ministry of Foreign Affairs accused Iran of failing to cooperate with the probe or hand over suspects in the case, stating that 'The Argentine Republic will not tolerate grievances or interference from a State that has systematically failed to comply with its international obligations and that persists in obstructing the progress of justice.'

Microsoft AI is aggressively expanding its internal capabilities with the release of three new foundational models, marking a significant step in its strategy to compete directly with OpenAI and Google. The new suite, developed by the MAI Superintelligence team, includes tools for transcription, voice generation, and video creation, all centered around a 'Humanist AI' philosophy. The Trinity of Multimodal Models: MAI-Transcribe, Voice, and Image The announcement details three distinct models designed to handle different aspects of human-machine interaction: MAI-Transcribe-1: A high-speed speech-to-text tool that supports 25 different languages. It is reported to be 2.5 times faster than Microsoft's previous Azure Fast offering. MAI-Voice-1: An advanced audio-generating model capable of producing 60 seconds of audio in just one second. It allows users to create custom voices, enhancing personalization. MAI-Image-2: A video-generating model that was originally tested on MAI Playground and is now being rolled out to a wider audience via Microsoft Foundry. Pricing Strategy: Undercutting the Giants Microsoft is leveraging cost as a primary differentiator in a crowded market. The company’s blog post highlights that these models are significantly cheaper than those offered by Google and OpenAI. MAI-Transcribe-1: Starts at $0.36 per hour. MAI-Voice-1: Costs $22 per 1 million characters. MAI-Image-2: Pricing is set at $5 per 1 million tokens for text input and $33 per 1 million tokens for image output. The Humanist AI Philosophy and Suleyman's Strategy Leading the MAI Superintelligence team is CEO Mustafa Suleyman, who emphasized a distinct approach to model development. The strategy focuses on 'Humanist AI,' prioritizing human-centric communication and practical utility over raw performance metrics. Suleyman wrote in a blog post that the models are optimized for how people actually communicate. Outlook: A Dual-Track AI Strategy Despite releasing its own proprietary models, Suleyman reaffirmed Microsoft's commitment to its partnership with OpenAI. He noted that recent renegotiations of the partnership have granted Microsoft the autonomy to pursue this superintelligence research. This suggests a dual-track strategy where Microsoft both invests billions in OpenAI and builds its own stack to ensure competitive pricing and redundancy in the market.

A US court has dismissed a lawsuit from WhatsApp's former security chief, who alleged that parent company Meta ignored internal flaws he flagged about the messaging app's digital defenses.Abdullah Baig, who claims he was fired in retaliation for raising these concerns, had alleged that billions of users had been put at risk because of these vulnerabilities. Thousands of employees could view sensitive user data, including profile photos and location, Baig claimed in the lawsuit filed in September. A judge ruled he had not presented enough evidence to move forward.The US district court in northern California ruled last month to dismiss Baig's claims, with the judge, Laurel Beeler, writing on 19 March that 'the complaint does not contain sufficient facts to show that the plaintiff reported violations of SEC rules or regulations.'Baig was head of WhatsApp's security division from 2021 to 2025. He said he had expressed concerns about cybersecurity issues to his supervisor five times but was ignored; he also said he wrote directly to Meta's CEO, Mark Zuckerberg, about what he saw as a violation of US Securities and Exchange Commission rules and escalating retaliation against him. He also claimed that the company didn't fix the hacking of more than 100,000 accounts daily – and focused instead on user growth. At the time, WhatsApp said in a statement that he was 'a former employee dismissed for poor performance' who had filed a suit based on distorted claims.A WhatsApp spokesperson said: 'This ruling reaffirms what we've said all along: These claims have no merit. We're proud of our strong record of protecting people's privacy and security, and will continue building on it.'Baig's lawyer suggested in a statement emailed to the Guardian that the legal fight was not over. 'Mr Baig is not done fighting for users,' said Wilmer Harris, who represents Baig. 'The judge dismissed on pleading grounds, not merit, and we look forward to addressing those deficiencies and ensuring Meta has to finally engage with the substance of Mr Baig's allegations.'
