Nasdaq 100 Resilience Hides Yen, Credit Risks as AI Demand Tops $115B

The Nasdaq 100's resilience masks a rare divergence — AI demand tops $115 billion while yen strength, credit spreads and Treasury yields all tighten.

"The real risk to tech stocks isn't AI demand — it's the macro environment and system leverage suddenly turning," said Rich Privorotsky, head of the Goldman Sachs trading desk.

Since mid-August, tech-sector CDS spreads have widened while the Nasdaq 100 has barely reacted — unlike July, when similar credit stress coincided with a visible pullback. US Treasury yields have climbed, pressuring high-valuation tech names, yet megacap stocks remain resilient. The S&P 500's six-month realized correlation has fallen to 11, a level last seen before the January 2018 "Volmageddon" episode.

With SPX straddle prices near yearly lows, options markets are pricing minimal risk of large moves. If price finally breaks in either direction, volatility could snap back violently, forcing a rapid repricing across US equities and global risk assets.

Frontier AI models continue to push past previously intractable problems. OpenAI has proposed a solution to the Navier-Stokes equations, and its new Astra model was trained on more than 100,000 GPUs at 70 to 100 megawatts of peak power — a step change in capability over prior generations. Demand shows no sign of cooling. Google Cloud's AI orders exceeding $100 million have more than doubled both quarter over quarter and year over year. AI server payback periods have compressed to under two years, and roughly one year for operators using custom silicon. Broadcom said actual AI demand already exceeds its $115 billion fiscal 2027 outlook.

The constraint on industry expansion has shifted from demand to electricity supply, data center siting and supply-chain capacity. AI-related debt sold this year has reached nearly $500 billion through early August, about a fifth of all higher-rated US issuance, according to Goldman Sachs analysts.

Yen carry trade looms as BoJ tightening bets build

Yen appreciation is emerging as the most consequential macro variable. As markets price further Bank of Japan tightening and Japanese capital repatriation, the yen keeps strengthening. US Treasury Secretary Scott Bessent's recent assertion — "I'm the house now... you can bet against me all you want" — has done little to reverse the trend.

The risk centers on yen-funded carry trades. If Japanese capital accelerates homeward, domestic bonds and equities could absorb more flows while forcing deleveraging in US markets. Historically, yen strength has correlated with falling risk appetite and rising volatility. The Nasdaq 100 has shown greater tolerance this cycle, but whether that reflects genuine resilience or incomplete macro transmission remains unconfirmed.

Credit markets are already flashing warnings. Since mid-August, tech CDS spreads have widened steadily. In July, similar widening coincided with a Nasdaq 100 pullback; this time equities have shrugged it off. Rising Treasury yields should further pressure high-valuation tech names, yet large-cap stocks have absorbed the pressure.

Volatility compression sets up the next move

The most telling signal may be how compressed volatility has become. The S&P 500's six-month realized correlation at 11 has occurred only twice in the past 25 years — in February 2007 and January 2018, the latter preceding the Volmageddon crash. Analyst Garrett at Goldman Sachs noted that such extreme low correlation rarely persists, and index volatility and convexity tend to return quickly.

SPX straddle prices near yearly lows suggest the market is underpricing the probability of large moves. The combination of strengthening AI fundamentals, deteriorating macro signals and a Nasdaq 100 that refuses to pick a direction creates conditions for a violent single-directional move once price finally breaks.
