Bond Market Skepticism on AI Growth
9 hours ago7 min read4 comments

The deafening roar from the technology sector would have you believe that artificial intelligence is not just the next big thing, but the only thing, a force so transformative it’s already reshaping the global economic order. Tech titans report staggering earnings fueled by AI demand, venture capital flows like water into nascent startups, and headlines proclaim a new industrial revolution.Yet, a quiet but profoundly significant counter-narrative is emerging from a far more seasoned and skeptical corner of the financial world: the bond market. Here, amidst the complex calculus of inflation expectations, long-term growth forecasts, and yield curves, the message is one of profound doubt.The signal from fixed income is clear—investors remain unconvinced that the current AI frenzy will translate into the kind of sustained, widespread productivity growth and economic expansion that would fundamentally alter the long-term trajectory of developed economies. This isn't a dismissal of AI's impressive capabilities, from generative large language models to advanced automation; it is, rather, a sober assessment that these technological leaps have yet to prove they can overcome the powerful structural headwinds of aging demographics, soaring public debt, and deglobalization that have kept interest rates and growth subdued for decades.The bond market, with its trillion-dollar stakes and institutional memory, is essentially asking the trillion-dollar question: where is the tangible, macroeconomic evidence? Historically, genuine general-purpose technological revolutions—the advent of electricity, the personal computer, the internet—manifested in the data long after the initial hype cycle. They showed up as a sustained multi-year acceleration in productivity growth, a metric that has remained stubbornly low in the United States and other advanced economies since the early 2000s.The current AI boom, for all its promise, has not yet moved that needle in any statistically significant way. The Federal Reserve, the European Central Bank, and other major institutions have not meaningfully revised their long-run potential growth estimates upward, a telling indicator that the central bankers, who live and breathe this data, share the bond market's caution.What accounts for this stark disconnect between the unbridled optimism on Wall Street's tech-heavy Nasdaq and the cautious pessimism embodied in Treasury yields? Part of the explanation lies in the inherent nature of the two markets. Equity markets are forward-looking and speculative, pricing in potential future earnings and growth stories, often rewarding narrative and momentum.The bond market, by contrast, is the realm of cold, hard reality—it discounts the long-term path of inflation and real growth, and its participants, often large pension funds and insurance companies with multi-decade liabilities, are inherently more risk-averse and focused on the durability of cash flows. They are looking past the current capex surge from tech giants building out AI infrastructure and asking a more fundamental question: will this investment lead to a broad-based increase in corporate profitability and worker output across the entire economy, from manufacturing and logistics to healthcare and professional services? Or will its benefits be narrowly concentrated, accruing primarily to a handful of already-dominant platform companies, thereby exacerbating inequality and failing to generate the kind of rising tide that lifts all boats? Another critical factor is the inflationary versus deflationary impact of AI.The bullish equity narrative often posits that AI will be powerfully deflationary, automating tasks and driving down costs. The bond market, however, is considering a more complex scenario.The initial investment phase is inherently inflationary, as seen in the soaring demand for advanced semiconductors, data centers, and energy, which puts upward pressure on certain commodity prices and capital goods. Furthermore, if AI does lead to significant job displacement without a corresponding creation of new, high-value roles, it could suppress aggregate demand, creating a stagflationary mix of weak growth and persistent inflation in essential services.This nuanced risk is something the bond market is uniquely positioned to price, and its current skepticism suggests it sees a higher probability of a messy, complicated transition rather than a smooth, deflationary boom. Expert commentary reflects this divide.Prominent tech CEOs and venture capitalists speak of a 'Cambrian explosion' of AI-driven innovation. Yet, esteemed economists like Northwestern's Robert Gordon, author of *The Rise and Fall of American Growth*, remind us that the productivity impact of recent technological advancements has been disappointingly narrow compared to the epoch-defining innovations of the past.The bond market is effectively siding with the Gordons of the world for now, demanding more than just hype and promising prototypes. It wants to see the data in the GDP reports, the productivity statistics, and the core inflation readings. Until then, the disconnect will persist, serving as a crucial reminder that for all the buzz in Silicon Valley, the ultimate judge of AI's economic worth will be the silent, relentless, and unsentimental machinery of the global bond market, which has a long history of deflating the most captivating of stories with the sobering weight of hard evidence.
