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 could disrupt bank deposits. Why Wall Street may be overreacting
Banking analysts Gerard Cassidy and Mike Mayo consider the risk that AI agents could pull deposits to be real but exaggerated, since customers value trust and convenience. Financial stocks fell after Meta launched its Muse personal agent on Sept. 8, with Bank of America down 18% and Charles Schwab down 14% through Wednesday's close, though the Fed's September rate increase also weighed on the sector. A Deloitte survey found 72% of bank customers hesitate to share financial information with generative AI tools, and just 49% trust AI-generated banking information compared with 79% who trust bank websites. Executives including Wells Fargo's Charlie Scharf and Schwab's Rick Wurster argued that customers are slow to move money, while JPMorgan's Jamie Dimon said the bank is blocking outside agents that rely on shared login credentials. The article notes that deposit competition could squeeze bank profits, that savings accounts are more exposed than checking accounts, and that liability remains unresolved if an agent misdirects funds.
- US , European watchdogs intensify scrutiny of AI risks at banks
U.S. and European banking regulators are intensifying scrutiny of AI risks as increasingly autonomous systems raise concerns about cyberattacks and financial stability, according to six people familiar with the matter. Three major U.S. regulators, including the Federal Reserve, are asking banks about advanced AI models, including Chinese-developed technology, AI agents used in cyber defense, and control over autonomous systems. In Europe, the Bank of England and the ECB are pressing banks to strengthen recovery plans, with the ECB's end-October deadline for plans to counter AI-enabled cyber threats. U.S. regulators have not yet prescribed specific requirements, and the OCC, FDIC and Fed declined to comment. BCG's Sukand Ramachandran argued that rapid recovery matters as much as prevention, since without separate clean data copies a serious attack could lock customers out of accounts.
- JPMorgan's Dimon Sees Benefits From AI, Warns of Risks
JPMorgan Chase Chairman and CEO Jamie Dimon, speaking at an Economic Club of Chicago event, says AI brings both benefits and risks. He says JPMorgan has used AI since 2012 for risk, fraud, marketing, underwriting, design and customer service, and expects it to save lives through medical advances and new materials, and to cut the roughly 45,000 annual street deaths by up to 80%. Dimon also warns that AI can uncover many software vulnerabilities, while industries such as water, some government bodies and some hospitals have essentially zero protection and are exposed to state actors, terrorists and criminals. He says the threat is not existential but requires urgent action, with each industry protecting itself and its vendors, starting with six of 20 industries, and that the government needs help from the private sector. He adds that China shares a common interest in tackling the problem.
- Wells Fargo CEO Dismisses AI Deposit Flight Concerns as 'Overdone'
Investors have recently worried that artificial intelligence tools could threaten the deposit bases of banks and brokerages. The concern is that AI could help customers automatically shift cash out of low-paying accounts into higher-yielding options elsewhere.
- 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.

- Small-Cap Stocks Just Did Something They Haven't Done Since 2018. Is It Finally Time to Buy?
The Russell 2000 rose 2% in the week ended Oct. 23, snapping six straight weekly declines, its longest losing streak since 2018, while the S&P 500 and Nasdaq 100 both fell. The author links the divergence to the 10-year Treasury yield, which has fallen from a 5.36% peak in early October to below 5% as AI spending concerns drove a flight to safety, and notes that small-caps have been about twice as sensitive to Treasury yields as large-caps, according to State Street. Small-cap earnings are expected to grow more than 20% year over year, while the Russell 2000 trades at around 18 times earnings. The risk is that futures still price in two or three more quarter-point rate hikes by mid-2027, and a reversal in long-term yields could quickly fade any rebound. The iShares Russell 2000 ETF (IWM) is about 9% below its August all-time high.
- Proposal to Cut Penalties for Businesses Dormant for Years
The Ministry of Finance is seeking comments on a draft government resolution to reduce penalties for late tax filings by taxpayers that have ceased operations without completing deregistration (status 03) or are no longer at their registered address (status 06). Businesses that submit missing returns would face 30%, 50% or 70% of the current penalty, depending on when they finish, with the lowest rate applying through June 30, 2027. More than 753,000 taxpayers inactive for over 10 years could also have their tax codes terminated, provided they have no tax debt and are not under inspection or prosecution, after a 30-day public notice period. The ministry estimates about 1.6 million returns could be filed, reducing penalties by roughly VND 12,670 billion if completed by June 30, 2027. The policy excludes cases involving signs of tax evasion or tax fraud.
- Why Vertiv Stock Soared Today
Vertiv shares jumped 16.48% on Wednesday after its leadership offered bullish comments on the AI market. Third-quarter net sales rose 61% year over year to $4.3 billion, with the Americas, Asia-Pacific and EMEA segments up 75%, 50% and 23%, respectively, as its power and cooling products are increasingly used in AI data centers. Despite concerns that rising debt and higher interest rates could slow construction, CEO Giordano Albertazzi said the infrastructure build-out is accelerating. Adjusted earnings rose 78% to $2.21 per share, above Wall Street's projection of $1.82, while operating and free cash flow climbed 64% and 50% to $794 million and $652 million. Management now expects full-year adjusted earnings to rise 70% to $7.15 per share.
- China's tech darlings are losing their shine. Here's what's behind the sell-off
China's technology stocks are losing momentum as investors question whether the AI boom can generate profits high enough to justify rich valuations. The STAR 50 Index, which tracks 50 of the largest and most liquid companies on Shanghai's STAR Market, has fallen more than 40% from its July peak. The sell-off began as profit-taking after a strong rally that accelerated when DeepSeek emerged in early 2025, but has widened into doubts about whether earnings can support current prices. Battery giant CATL, down 37% year to date, illustrates the problem: its third-quarter revenue rose roughly 59% but net profit only about 15%, as competition, product mix and changes to taxes and rebates squeezed profitability. Analysts say a sustained rebound would require stabilizing earnings, clearer returns on AI spending and stronger domestic demand.
- Russia says there is “no room” for European countries at three-way Ukraine talks
Russian presidential aide Yury Ushakov said a three-way Russia–Ukraine–US negotiation will take place in Abu Dhabi, UAE, after 4 November, but no specific date has been set. He denied reports that talks could take place on 4 November, saying Moscow has not sent any such signals. Ushakov also said European countries will not be invited to the negotiating table and could only attend by buying tickets. US President Donald Trump said a meeting with Vladimir Putin and Volodymyr Zelensky would be arranged “very soon.” Separately, governor Dmitry Milyaev said a large-scale Ukrainian drone attack in the early hours of 28 October sent debris falling on Novomoskovsk, damaging an apartment block, private houses and infrastructure in a nearby industrial zone.
- Monster Beverage vs. On Holding: Which Is the Better Growth Stock?
The article compares Monster Beverage (MNST) and On Holding (ONON), two fast-growing consumer companies in different industries. Monster reported FY 2025 revenue of nearly $8.3 billion, up about 10.7%, and net income of close to $1.9 billion, a net margin of roughly 23%, but it relies heavily on Coca-Cola's distribution system and faces competition from Red Bull and PepsiCo. On Holding posted FY 2025 revenue of about $3.6 billion, up 30%, and net income of roughly $246 million, while heavy marketing and store expansion can weigh on margins. In the second quarter of 2026, Monster's sales rose 20.2% to $2.5 billion and net income increased 19.6% to $584.5 million. Over the same period, Monster's stock gained 17.8% versus 12.9% for the S&P 500, while On Holding's shares fell 30.5%; the author says he would prefer Monster as a long-term holding and expects that trend to continue into 2027.
