October CPI's 0.4% Jump Pushes the 10-Year Yield Back to 5%, Reviving Fed Hike Talk While AI Debt Splits the Chip Trade

On Nov. 13, 2026, the Bureau of Labor Statistics' October Consumer Price Index (CPI, the government's main measure of how much prices for everyday goods and services have changed) rose 0.4% from the prior month. The increase was driven largely by core services inflation, the cost of items like rent, insurance and medical care that strip out volatile food and energy prices. The reading pushed the yield on the 10-year Treasury note back to 5%, because bond investors demanded higher compensation for the risk that inflation stays stickier than hoped. That move revived talk that the Federal Reserve might need to raise interest rates rather than cut them, upending the rate-cut narrative that had supported stocks in recent months. A second storyline ran through the chip sector. CoreWeave, a cloud company that rents out Nvidia chips for AI workloads, reported third-quarter 2026 revenue up 168% with expanding margins. The Financial Times separately reported the company is planning a multibillion-dollar debt deal backed by its chip assets, using its GPUs as loan collateral to fund more data-center construction. That reassurance about CoreWeave's ability to carry debt triggered a broad chip rally led by Micron, a maker of the memory chips used in AI servers, and the rally rippled into memory chipmakers more broadly because CoreWeave is a major buyer of their output. The relief was not universal: Applied Digital, another data-center operator that also relies on borrowed money to build AI infrastructure, was downgraded the same day, underlining that the leverage question CoreWeave appeared to solve for itself still worries investors elsewhere. Just as that chip rally built, a leak of Nvidia's China-specific chip plans surfaced, pushing Nvidia's stock toward a 52-week low, the lowest price it had traded at in a year. The episode marked a shift in AI skepticism: having spent weeks focused on whether CoreWeave could service its debt, traders turned instead to whether Nvidia's underlying demand picture was as strong as assumed. Separately, OpenAI reported quarterly revenue rising to $10 billion even as it posted steep losses, a reminder that the AI buildout is generating revenue growth but not yet profit for even its most prominent players. TSMC, the Taiwanese chipmaker that manufactures Nvidia's processors, moved the other way, becoming a direct investor in the AI labs it supplies, a bet that owning a stake in its customers secures demand even if any single customer wobbles. Oil stocks rallied on renewed Iran tensions the same day Tehran pressed its case at COP31, the United Nations climate conference, underscoring that geopolitical risk can move crude prices independent of the diplomatic backdrop. Shipping companies DFDS and Hapag-Lloyd both flagged that freight rates are staying elevated, a cost pressure that eventually feeds into the same consumer prices the CPI report measures. Chemical distributor Brenntag missed its third-quarter earnings estimates but kept full-year guidance at the top of its previously stated range, a signal that management still expects whatever caused the miss to be temporary. Insider activity added a separate undercurrent. A Royal Caribbean director sold $159.8 million of stock, an amount that dwarfed a fresh cluster of smaller insider exits: Prudential Financial's SVP Boyle sold $338,743, Ibex's chief people officer sold $354,831, Tapestry's chief people officer and chief legal officer each sold roughly $1.5 million, and Spero Therapeutics' CEO sold $42,485 in a tax-related transaction. Not every signal pointed the same way. One director bought $3 million of stock even as insiders elsewhere kept selling, a reminder that insider activity reads differently depending on which single name is doing the buying. Going into the next session, two questions remain open. First, whether the Fed treats the 0.4% October CPI print and the 10-year yield's return to 5% as reason to reconsider rate cuts, which will likely hinge on upcoming Fed commentary and the next inflation reading. Second, whether CoreWeave's chip-backed debt deal, still only planned according to the Financial Times and not yet finalized, actually closes on favorable terms. That outcome would settle whether the rest of the AI-leverage trade, Applied Digital included, can follow the same playbook, or whether Nvidia's demand picture needs to improve first. The Buy List 2026 model portfolio, which holds €120,000 invested across energy, shipping and technology positions, closed valued at €124,796, a total return of 4.00% since inception, or 3.31% on price alone, with the gap made up of dividends and currency effects. The spread between its best and worst holdings captured the day's AI-and-crypto divergence: GameStop (GME) was up 41.19% and MicroStrategy (MSTR), a company whose balance sheet is built around bitcoin holdings, was up 31.18%, while Vonovia (VNA.DE), the German residential landlord, was down 29.32% and Tesla (TSLA) was down 18.90%. The gap is a reminder that the portfolio's aggregate gain is being carried by a narrow set of speculative, AI- and crypto-adjacent names even as more traditional holdings lag.
