• Jamie Dimon Warns AI Agents Could Be ‘Treacherous’ for Banks, but Researcher Says There May Be Another Reason to Worry

  JPMorgan Chase CEO Jamie Dimon has warned that AI agents accessing customer accounts pose serious security risks, while AI researcher Andrew Yoon of Civ AI argues banks may also resist the technology over profit concerns. Yoon said agents could help customers move idle cash into higher-yield savings accounts, a significant threat to bank profits if millions of customers do so. Speaking at the Economic Club of Chicago on October 14, Dimon said agents may not act properly on users’ behalf, which could be “treacherous” for the bank too. Reuters reported that JPMorgan, Morgan Stanley, Bank of America and other major lenders are restricting third-party AI agents, while banks say the restrictions mainly protect customers from security breaches. McKinsey estimated in April 2026 that shifting just 5% to 10% of checking balances into higher-yield accounts could cut banks’ deposit profits by at least 20%.

• AI agents are inside U.S. bank accounts. But nobody knows how.

  The host calls the past 48 hours the most serious period in cybersecurity history, dubbed Black October, with hundreds of AI-driven attacks hitting popular websites and apps such as Slack, Facebook and Etsy. Major U.S. banks are detecting unauthorized AI agents in customer accounts that they cannot tell apart from humans. Cited incidents include a PHP flaw said to affect an estimated 70% of websites, a GitLab vulnerability rated 10 out of 10 in severity that has existed since 2014, a Signal bug that could turn on the microphone and camera after a call ends, and a data breach at the State Bank of India. Unable to tell whether their software is vulnerable, governments and companies worldwide have begun shutting down systems, while open-source AI models are being used for defense.

• Banks dealing with rogue AI agents is 'a problem that is facing us today'

  Arctic Wolf CEO and President Nick Schneider, speaking on Market Domination Overtime, discussed threats from AI agents to bank accounts. Citing Axios, he noted US banks such as JP Morgan and Bank of America are detecting third-party AI agents accessing customer accounts. He argued that open-source models and models from outside the United States are capable enough to build agents at scale to attack organizations, making this a current problem; the only defense against the speed of agentic attacks is trustworthy, economical agentic defenses, which is why Arctic Wolf built its agentic SOC. On privacy, he said many familiar privacy and cybersecurity challenges still apply, now arriving with greater speed and sophistication.

• RBC Weighs Blocking Meta's AI Agent Muse, CEO McKay Says

  Dave McKay, president and CEO of Royal Bank of Canada, said on Bloomberg Surveillance that the bank is considering blocking Meta Platform Inc.'s AI agent Muse from accessing its customers' information, but has not made a decision. He said the bank must protect consumers from data being scraped without consent or from fraudulent transactions, since the bank would be liable, and must balance that with the services customers want. McKay also said RBC has reinforced its internet-facing and market-facing software using the most advanced AI models, at considerable cost, and that cyber attacks are growing more complex, raising defense costs substantially for organizations.

• World leaders must wise up to threat of cyber - attacks or rogue fridges will be least of their worries | Heather Stewart

  At the IMF and World Bank annual meetings in Bangkok, IMF Managing Director Kristalina Georgieva warned that AI-boosted cybercrime could undermine trust in the financial system, citing hackers who pushed French supermarket fridges to 50C and spoiled food. She worried that many people could end up keeping cash in shoeboxes under their beds. JPMorgan CEO Jamie Dimon said the bank would not allow AI agents to operate on customers' behalf, while agents that move deposits to chase the highest savings rates could trigger rapid withdrawals and raise unresolved questions about liability. Bank of England Governor Andrew Bailey said, “If we don't have trust in money, we don't operate as a society.” The column says financial policymakers are alarmed by the collision between fast-moving AI and a financial system that now extends well beyond heavily regulated banks.

• G7 to Plan Exercises to Guard Against AI - Powered Cyberattacks

  G7 finance leaders have agreed to hold tabletop exercises simulating AI-powered cyberattacks on banks, Japanese Finance Minister Satsuki Katayama said at the IMF meeting in Bangkok. The drills would involve G7 finance ministries and central banks and could also include private financial institutions. In an Oct. 13 blog post, the IMF warned that frontier AI could accelerate both attacks and defenses, noting that in over 70 percent of reported cyberattacks this year, software providers had almost no time to patch vulnerabilities, a share more than double that of 2021, when providers typically had close to 300 days to fix them. Bank of England Deputy Governor Sarah Breeden said the bank is working with banks to prepare for recovery from AI-enabled breaches, calling AI a systemic risk. She said her biggest worry is a systemically important bank or core infrastructure being attacked and paralyzed.

• Cybercab Expansion Might Change The Case For Investing In Tesla Stock (TSLA)

  Tesla is expanding its Cybercab robotaxi service after regulators in Texas and Nevada authorized larger fleets and pilot operations in key U.S. cities. The article says this low-cost, software-heavy model could help Tesla build recurring service revenue on its EV base, but heavy spending on autonomy, chips and energy, along with R&D and capex, keeps auto margins under pressure. Third-quarter revenue was roughly flat year on year, while net income and EPS fell. A Turo partnership lets renters use verified FSD Supervised cars, with a one-month trial for eligible U.S. hosts. Consensus analyst forecasts put Tesla at US$185.3 billion in revenue and US$17.8 billion in earnings by 2029, with 21.4% yearly revenue growth, while the lowest forecasts reach only US$136.0 billion and US$4.6 billion.

• Medtronic Just Retired 55 Million Shares Without Spending Cash. Is the Stock a Buy?

  After spinning off its diabetes business as MiniMed (MMED), Medtronic (MDT) received about 55 million of its own shares in the final results of its oversubscribed split-off and exchange offer, so future net income will be spread across fewer shares, which the article says can support EPS growth. It gives three points: Medtronic has raised its dividend for 49 consecutive years and could reach the 50-year mark if it raises the dividend in 2027 as expected, while only 59 of roughly 7,000 major U.S.-listed stocks are on the “Dividend King” list; and its trailing cash dividend payout ratio is just under 60%. Revenue in the first quarter of fiscal 2027 rose nearly 14% to $9.8 billion, and EPS rose 15% to $1.45. Fiscal 2026 revenue reached $36.4 billion, up 8.4%, supported by more than 50 new FDA approvals and clearances. The stock trades at about 16 times forward earnings and 24 times trailing earnings, below Johnson & Johnson, Edwards Lifesciences, Abbott Labs and Stryker.

• Pentagon urges Baltic NATO members to stop 'provoking' Russia

  According to four sources close to the matter, US Under Secretary of Defense Elbridge Colby has privately urged officials in Lithuania, Latvia and Estonia to refrain from 'provoking' Russia, and pressed Estonia to be cautious in its public statements. The Pentagon declined to comment on the private exchanges, and it is unclear whether other NATO allies received similar warnings. The message follows sharp rhetoric from Baltic leaders, including Estonia's prime minister comparing Vladimir Putin to a 'cornered rat' and Latvia's foreign minister accusing Russia of 'state-sponsored terrorism' over an explosive-laden drone found at a German airport, which Putin denied. The development comes as Washington temporarily eased sanctions to allow Russian diesel imports after a 9 October call between President Trump and Putin.

• AMZN Q3 deep dive: cloud surge and AI investments drive mixed market reception

  Amazon's third-quarter 2026 revenue rose 12.1% year on year to $201.9 billion, in line with the $202.3 billion analyst estimate, while GAAP EPS of $1.89 missed the $1.96 expectation by 3.4%. Operating margin widened to 13.9% from 9.7% a year earlier. AWS grew 39.3%, its fastest pace in nearly five years and an acceleration for a sixth straight quarter, driven by AI infrastructure demand and custom chips such as Trainium and Graviton, which saved customers more than $2 billion in Q3 alone. Management expects next-quarter revenue of about $243.5 billion and said it believes AWS can grow north of 40% in 2027 and 2028, although near-term profitability may fluctuate with higher operating costs. Prime members ordering groceries with same-day delivery have tripled, and advertising growth is expected to return to the high teens after a slowdown tied to Prime Day timing.
