Bond Market Challenges Nvidia-Led AI Rally

Reporting by London Loves Tech quotes deVere Group CEO Nigel Green arguing that rising bond yields are beginning to challenge the concentration of market gains in Nvidia and other AI-linked megacaps. London Loves Tech states the S&P 500 has surged roughly 12% since April and that the US 10-year Treasury yield has climbed to its highest level in more than a year as oil trades above $100 a barrel. The piece quotes Nigel Green: "If 10-year Treasury yields keep moving toward 5%, investors are going to stop paying 30, 40 or 50 times earnings for growth stocks," and it also quotes him saying, "Bond markets are now challenging that in a serious way." Seeking Alpha and MSN published similar summaries of deVere's warning.

London Loves Tech links the yield move to higher oil following disruptions near the Strait of Hormuz and reports that a key inflation measure, the one-year, one-year inflation swap, has climbed above 4% for the first time since early 2025. The article characterizes expectations for Federal Reserve rate cuts as reversing, and reports Nigel Green stating, "The AI trade works best in a falling-rate environment." These are presented as market observations and quoted commentary rather than central-bank communications.

Editorial analysis: Companies and sectors with long-duration earnings streams are sensitive to discount-rate moves; rising Treasury yields increase the discount applied to future profits, which can reduce present valuations across growth-heavy indices. Industry reporting during similar episodes shows that market leadership concentrated in a few megacaps tends to widen drawdowns when macro factors shift investor risk pricing.

Editorial analysis: The coverage frames this as a macro crosswind to an otherwise narrow, AI-driven rally. For portfolio construction and model-risk management, higher yields and elevated inflation expectations can alter assumptions used in valuation models, stress tests, and backtests that rely on stable discount rates. For quant teams, scenario sets that had been calibrated to gradually falling rates may understate downside exposure when yields reprice quickly.

• •Reported path of the US 10-year Treasury yield and whether it approaches 5%, as cited in London Loves Tech.
• •Oil-price trajectories tied to Strait of Hormuz disruptions, which the article links to rising inflation pressures.
• •Market-implied short-term inflation measures such as the one-year, one-year inflation swap and swaps breakevens cited in the reporting.
• •Changes in consensus expectations for Federal Reserve cuts; the article notes those expectations are reversing according to market prices.

Editorial analysis: Observers should monitor whether breadth metrics behind the S&P 500 widen or remain concentrated. In prior cycles, a breakout of breadth deterioration alongside rising yields has driven significant reweighting away from megacaps toward cyclical or value sectors.
