The US 10-year yield climbs to a one-year high as oil stays above $100 and inflation expectations breach 4%. deVere's Nigel Green warns the AI rally faces a serious test from bond markets.
Alpha Score of 67 reflects moderate overall profile with strong momentum, poor value, strong quality, moderate sentiment.
The US 10-year Treasury yield has climbed to its highest level in more than a year. Crude oil is holding above $100 a barrel after Strait of Hormuz disruptions. A key inflation expectations gauge – the one-year, one-year inflation swap – has breached 4% for the first time since early 2025. That combination is challenging the extreme valuations that have powered Nvidia (NVDA) and a narrow group of AI-linked megacaps.
“If 10-year Treasury yields keep moving toward 5%, investors are going to stop paying 30, 40 or 50 times earnings for growth stocks,” said Nigel Green, CEO of deVere Group, one of the world’s largest independent financial advisory firms. “This is where the pressure on AI valuations becomes much more serious.”
The S&P 500 has surged roughly 12% since April’s temporary Middle East ceasefire reignited risk appetite. The bulk of that gain is concentrated in a handful of AI-related stocks. At the same time, the 10-year yield has risen as investors reprice inflation risks tied to oil above $100 and expectations that interest rates could stay elevated for much longer.
“Wall Street has convinced itself AI can outrun interest rates,” Green said. “Bond markets are now challenging that in a serious way.”
High-growth tech companies are especially vulnerable to rising yields because a large portion of their valuation rests on future earnings expectations. When bond yields rise, the discount rate applied to those distant profits increases, reducing the present value investors are willing to pay. That mechanical relationship matters less when yields are stable or falling. It becomes a direct headwind when they move sharply higher.
“The AI trade works best in a falling-rate environment,” Green explained. “Bond markets are suddenly pointing in the opposite direction. Markets that spent months pricing aggressive Federal Reserve rate cuts are now rapidly reversing those expectations.”
Crude oil sustaining above $100 a barrel following disruption linked to the Strait of Hormuz is intensifying fears that inflation pressures are rebuilding across the global economy. Government borrowing costs have risen sharply across developed economies as investors reassess the outlook for inflation, central bank policy, and fiscal spending. The cheap-money environment that helped ignite the AI rally is fading.
“Cheap money has been one of the foundations of the explosive move in AI stocks,” Green said. “If yields continue moving sharply higher while oil remains elevated, the risk increases that bond markets – not earnings – become the catalyst for the next tech sell-off.”
The one-year, one-year inflation swap climbing above 4% reinforces concern inside bond markets that central banks may struggle to bring inflation fully under control. Markets that months ago priced aggressive Federal Reserve rate cuts are now moving sharply in the opposite direction. That repricing is already visible in the inflation swaps market.
Nvidia has become the clearest symbol of the concentration driving the current market rally. The company’s explosive gains have helped propel US equity indices to repeated record highs, while a relatively small group of megacap tech stocks now accounts for a disproportionate share of overall market performance.
Green warned that concentration risk across US equities is becoming increasingly dangerous.
“Nvidia is now functioning almost like a macro asset rather than simply a semiconductor company,” he said. “When one theme and a handful of stocks are carrying such a large percentage of market momentum, any repricing in yields can hit the broader market very quickly.”
| Risk Factor | Current Level | Implication for AI Stocks |
|---|---|---|
| US 10-year yield | Trending toward 5% | Reduces present value of future earnings |
| Crude oil | Above $100/bbl | Reinforces inflation persistence |
| 1-year,1-year inflation swap | Above 4% | Signals rates may stay higher for longer |
| S&P 500 concentration | ~12% gain since April | Vulnerability to a mean-reversion shock |
Nvidia remains the most exposed single stock. The company’s Alpha Score stands at 67/100 (Moderate) per AlphaScala data, with the stock trading at $220.60, down -0.77% on the day. The combination of rising yields and an already elevated multiple leaves little margin for error in the next earnings cycle.
Other high-growth tech names in the AI ecosystem face similar mechanics. Any broader rotation out of growth into value or defensive sectors would amplify the sell-off, particularly if the 10-year yield breaches the psychological 5% level.
For traders watching this risk event, the key confirmations are straightforward:
Each datapoint strengthens the case that bond markets are repricing growth stock valuations.
Major equity corrections are often preceded by instability in fixed income markets rather than in equities themselves. Bond investors tend to react earlier to inflation risks, tightening liquidity conditions and deteriorating fiscal dynamics. Equity markets frequently adjust later – and often aggressively.
Several developments would reduce the risk:
“Wall Street has convinced itself AI can outrun interest rates,” Green said. “Bond markets are now challenging that in a serious way.” The disconnect between the two markets is the core risk event to watch.
Date-driven triggers include:
The concentration risk highlighted by Green is measurable: the top five stocks now account for a historically large share of S&P 500 market cap. If yields break out, the unwind could be faster than the ramp was.
