Anthropic’s Claude Mythos to be Presented to the Financial Stability BoardAnthropic will brief the Financial Stability Board (FSB), chaired by Bank of England governor Andrew Bailey, on the cyber‑defence implications of its Claude Mythos model, which has raised alarm among security experts.Mythos is not being released publicly; access is limited to select tech firms and banks such as Apple and JP Morgan.The briefing follows a report by the Financial Times and confirmation from a source familiar with the discussions.The FSB’s membership includes senior officials from the US, UK, Australia and China.Quantifying Mythos’ New Cyber‑Testing PerformanceThe UK’s AI Security Institute (AISI) noted a “notable capability jump” in the version shown to banks. In the “cooling tower” test, Mythos succeeded in 3 out of 10 attempts – a first for any model evaluated by AISI.Previous iterations had not completed the test.AISI reports that the length of autonomous cyber tasks has doubled within months.Implications for Global Financial CybersecurityThe briefing comes as the International Monetary Fund (IMF) warned that AI‑driven cyber risks are rising for financial stability. Central bank leaders, including Goldman Sachs CEO David Solomon and JP Morgan CEO Jamie Dimon, have already expressed heightened awareness of Mythos’ capabilities.Cyber risk does not respect borders; inconsistent oversight could weaken the interconnected financial system.Experts caution that most breaches still stem from traditional weaknesses such as weak authentication.What the Next Phase of AI‑Driven Cyber Risk May Look LikeAISI is developing tougher hacking tests to track AI progress, while the FSB is expected to issue recommendations for coordinated oversight among regulators. If the trend of rapid capability gains continues, financial institutions may need to embed AI‑specific cyber‑defence measures into their risk frameworks.Potential for tighter collaboration between AI developers and regulators.Increased scrutiny of AI models before deployment in critical infrastructure.

Dimon’s Warning Over the Future of JP Morgan’s £3bn London HQJamie Dimon, chief executive of JP Morgan, told Bloomberg TV in Paris that the bank could abandon its planned £3 billion headquarters in Canary Wharf if a new Labour prime minister proves hostile to banks.Political Trigger: Potential Labour Leadership ChangeThe warning is tied to the uncertainty surrounding Keir Starmer. If Starmer is replaced by a successor who reverses the current “positive business environment” – especially after recent tax concessions – the project could be cancelled.Current plan: 23,000 UK staff, >50% to be housed in the tower.Location: Canary Wharf, London.Timing: announced November 2025, construction slated to start 2027.Financial Stakes: Cost, Tax Burden, and Staffing NumbersEstimated construction cost: £3 billion (≈ $3.8 billion).JP Morgan reported net income of $57 billion (£43 billion) in 2025.Dimon claims the bank has already paid roughly $10 billion in extra UK taxes (bank surcharge and levy).Requested discount on business rates for the tower.Broader Implications for the UK Financial Services SectorA withdrawal would signal to other foreign banks that political risk can outweigh the UK’s market size, potentially derailing planned IPOs and dampening investment banking activity.Investment banking sources warn IPO pipelines could be “derailed”.City stability is linked to consistent fiscal policy and leadership continuity.What Could Happen If a New Prime Minister Targets Banks?Analysts expect three possible scenarios:Renegotiation: JP Morgan seeks further tax relief or guarantees before proceeding.Project suspension: Construction is paused pending political clarity, increasing costs.Cancellation: The tower is scrapped, reducing UK office‑space demand and signaling a shift in foreign investment strategy.Stakeholders will watch the Labour leadership contest closely, as the outcome could reshape the UK’s attractiveness to global banks.

The Lead Investors in JP Morgan have been urged to vote in favour of splitting the role of chief executive and chair at America’s largest bank, amid concerns over the power wielded by its billionaire boss Jamie Dimon. The Proxy Advisers' Stance ISS and Glass Lewis, which issue advice to some of the world’s biggest fund managers on how to vote at annual investor meetings, have thrown their weight behind a shareholder resolution that would ensure two separate people hold the office of chair and chief executive “as soon as possible”. Investors are due to vote on the resolution at the bank’s annual general meeting on 19 May. The Data Analysis Dimon, who is worth an estimated $2.6bn (£1.9bn), has held the dual role for two decades. Holding the two most senior roles in a company is widely frowned upon in corporate governance circles, particularly in Europe, but not banned. The Impact Analysis “The size and complexity of JP Morgan suggests that it is difficult for any one person to run both the company and the board,” ISS said in its shareholder report. “The board is responsible for overseeing management and instilling accountability, and conflicts of interest may arise when one person holds both the chairman and CEO positions, thereby leading both the management team and the board which oversees it.” The Prediction The guidance has put the proxy advisers on a collision course with Dimon, who has held the chief executive and chair roles at JP Morgan since 2005 and 2006, respectively. The battle has also made its way to the White House. Trump in December signed an executive order aimed at reining in Glass Lewis and ISS, which he claimed were using their power “to advance and prioritise radical politically motivated agendas”.

The Executive SummaryEmployers are increasingly skeptical of the four‑day workweek label, seeing it as a threat to profitability despite growing legislative support and AI‑driven productivity promises.Employer Backlash Over the Four‑Day Workweek LabelWhen you mention “four‑day workweek” to a typical manager, the reaction is often an eye roll. Executives argue that paying five days’ wages for four days of work feels unfair, especially when they are already juggling countless deals.Legislative pilots in Europe—Belgium, Iceland and Lithuania—have mandated shorter weeks, and hundreds of UK firms have signed up for trials, yet many businesses remain hesitant.Adoption Figures and Labor Market PressuresBelgium, Iceland, Lithuania: national legislation requiring a four‑day week.UK: hundreds of companies have signed up for permanent trials.US tech leaders (Jamie Dimon, Elon Musk, Sam Altman) predict AI will eventually shrink the workweek.UK labour market: millions of job openings remain unfilled, driving employers to seek more hours, not fewer.Why the Stigma Undermines Flexible Work ArrangementsThe phrase “four‑day workweek” has become shorthand for laziness in the eyes of many senior leaders. This perception pushes companies to offer flexibility through remote work, compressed schedules, or generous paid‑time‑off instead of openly adopting the shorter week.Examples from the field show the concept already exists under different names: three 12‑hour shifts for full pay in veterinary practice, 10‑hour shifts with extra days off in manufacturing, and extensive PTO packages that effectively create a four‑day rhythm.Rebranding the Shorter Week for an AI‑Enhanced FutureIf AI delivers the promised productivity gains, the workweek may indeed shrink, but executives are likely to avoid the “four‑day” tag. New terminology such as “performance‑pay model,” “smart‑hours,” or “results‑based scheduling” could make the idea more palatable.By decoupling the benefits from the stigmatized label, businesses can retain talent, reduce turnover, and still reap the efficiency gains that AI offers.

Jamie Dimon, the CEO of JP Morgan, has stated that a potential downturn in the $3tn private credit market would not pose a significant threat to the stability of major banks. According to Dimon, while there are areas of weakness in the unregulated private credit industry, it does not present a 'systemic' risk to the financial system.Dimon made these comments during an earnings call on Tuesday, where he also noted that the actual credit quality had not deteriorated significantly, with only 'pockets' of weakness. He emphasized that very large losses in private credit would be needed before major banks were affected.The private credit market has faced growing concerns over potentially risky loans arranged by firms that lend to companies using investor money, outside the traditional regulated banking system. This has led to a multibillion-pound surge in withdrawals from some private credit funds, such as Blue Owl, which have had to cap the amount of money clients can withdraw.Despite these concerns, Dimon expressed that he is 'not particularly worried' about the impact on major banks. JP Morgan reported a 13% jump in first-quarter profits to $16.5bn, with revenues rising 10% to $49.8bn.

The US Treasury secretary, Scott Bessent, recently convened a meeting with major American bank chiefs in Washington to address growing concerns over the cyber risks associated with Anthropic's latest AI model, Claude Mythos. This model has reportedly exposed thousands of vulnerabilities in software and popular applications.The meeting, which included Jerome Powell, the Federal Reserve chair, and CEOs from prominent banks such as Goldman Sachs, Bank of America, Citigroup, Morgan Stanley, and Wells Fargo, was called to discuss the potential risks posed by this advanced AI technology. Jamie Dimon of JP Morgan was invited but could not attend.Anthropic has restricted the release of Claude Mythos to a limited number of businesses, including Amazon, Apple, and Microsoft, due to concerns that hackers could exploit the model's capabilities to compromise data security. The company has noted that the model uncovered vulnerabilities up to 27 years old that had not been previously identified.This development comes as the US government has designated Anthropic as a supply chain risk, a designation the company is contesting in court. The meeting highlights the increasing concern among regulators and financial leaders about the potential for AI to both enhance and threaten cybersecurity.

Jamie Dimon, chairman and chief executive of JPMorgan Chase, used his highly‑watched annual letter to shareholders to press the White House to strengthen economic cooperation with U.S. allies, warning that a decline in shared prosperity could produce "truly adverse consequences" for democratic nations.His message arrives as the Iran‑Israel conflict enters its sixth week, a war that has already rattled global energy markets. Economists cited in the letter caution that prolonged fighting could push oil prices above $170 a barrel, a level capable of triggering a worldwide recession.Dimon’s appeal is widely read as a thinly‑veiled rebuke of President Donald Trump. Earlier this year, Trump filed a $5 billion lawsuit against Dimon and JPMorgan, accusing the bank of “de‑banking” him. The timing of Dimon’s comments—just days after Trump’s aggressive rhetoric urging foreign governments to "go get your own oil"—underscores the growing rift between the bank’s leadership and the administration."Economic weakening of the world’s democracies or a fragmentation of their economic bonds could lead to truly adverse consequences," Dimon wrote. He warned that adversarial states aim to make allies less dependent on the United States, potentially turning them into economic “vassals” of hostile regimes.Beyond geopolitics, Dimon highlighted the broader macro‑economic outlook. He warned that the war could generate "sticky" inflation, higher commodity prices, and disrupted supply chains, which together may force interest rates higher than markets currently anticipate. He echoed other economists in warning that inflation could rise rather than fall in 2026.Despite these challenges, Dimon expressed optimism about the U.S. economy, affirming his belief that "the American Dream is alive." He also turned to emerging technology, noting that artificial intelligence could deliver breakthroughs in healthcare, manufacturing, and safety, ultimately shortening the work week and extending life expectancy.Dimon’s annual letter—spanning nearly 50 pages and more than 20,000 words—remains a barometer for Wall Street sentiment. In it, he also critiqued the administration’s tariff policy, arguing that while tariffs have forced renegotiations, a comprehensive foreign‑economic strategy should promote growth both for the United States and its partners.As transatlantic relations strain under soaring energy costs and divergent trade policies, Dimon’s call for a coordinated economic front underscores a pivotal moment: the United States must decide whether to lead a cohesive democratic coalition or risk ceding influence to autocratic powers.

JP Morgan's proposed 279,000 sq metre tower in Canary Wharf, which would serve as its European headquarters, is contingent on the UK government offering a business rates discount of up to 100% over a period of years. This potential sweetener could amount to hundreds of millions of pounds, as the site is estimated to generate up to £1.6bn in rates over 25 years.The development, which would house 12,000 JP Morgan staff, is part of a £3bn investment in London. The bank's CEO, Jamie Dimon, cited the UK government's priority on economic growth as a critical factor in the decision. However, documents from the local Tower Hamlets council reveal that JP Morgan is unlikely to progress with the project without clarity on the business rates incentive.The proposed discount has sparked controversy, as it would benefit a large corporation while potentially disadvantaging small businesses like pubs and restaurants that were recently hit with increased business rates in the budget. One proposal considers creating an enterprise zone around JP Morgan's development to enable time-limited business rates discounts.The negotiation highlights the significant influence of large corporations in securing favorable deals. Despite the potential economic benefits, including 7,800 construction-related jobs and an estimated £10bn contribution to the UK economy over six years, the deal raises questions about fairness and the cost to taxpayers.
