How credible is the claim that AI capex could be setting up the USA for a Japan style recession and deflation?

Evaluating the Economic Implications of AI Capital Expenditure: Could the U.S. Face a Japan-Style Recession?

Recently, I listened to an episode of the podcast “Better Offline,” where economist Paul Kedrosky shared some intriguing insights on the current economic landscape and the role artificial intelligence (AI) investment might be playing. His analysis raises concerns about how extensive AI-related capital expenditure (capex) could influence the U.S. economy, potentially setting the stage for a Japan-style recession characterized by prolonged stagnation and deflation.

The Case for Caution with AI Capex

Kedrosky pointed out that AI investments are often financed through debt that bears similar maturities and slightly higher yields compared to U.S. Treasuries. This dynamic has several implications:

1. Declining Demand for U.S. Debt: As AI firms and investors seek to finance their projects, the increased issuance of AI-related debt competes with government debt. Since AI debt offers relatively attractive returns, demand for sovereign debt may diminish, leading to increased borrowing costs for the U.S. government.

2. Impact on Treasury Yields: During debt auctions, when higher demand exists for AI-related debt, the U.S. government might be compelled to offer higher interest rates to attract bidders, thereby elevating treasury yields. This can have ripple effects on mortgage rates, business loans, and overall financial conditions.

3. Inflation Drivers and Potential Deflationary Pressures: Kedrosky suggested that, in the absence of AI-related investments, the economy might be in a deflationary state. Currently, inflation appears to be driven partly by the surge in AI capex and rising energy costs, which inflate prices across sectors. However, if AI investment diminishes or is stripped from the equation, these inflationary pressures may subside, potentially leading to a deflationary environment.

The Pendulum of Debt and Productivity

The concern extends to long-term sustainability. AI-driven productivity enhancements could theoretically offset high levels of corporate debt, but achieving such a balance would require extraordinary gains. Currently, much of AI’s contribution to economic growth relies on reducing labor costs rather than generating new demand, which can suppress consumer spending and weaken overall economic vitality.

Furthermore, Kedrosky noted that the economy’s reliance on continuous AI investment creates a “heads I win, tails you lose” scenario. Firms are reluctant to halt AI spending due to fears of losing competitive advantage, leading to persistent over-investment. However, this relentless spending is unsustainable; eventually, external shocks—such as rising borrowing costs or infrastructure failures—may force a pullback.

Potential Outcomes and Risks

When spending on AI and associated infrastructure declines abruptly, the economic effects could mirror Japan’s experience of decades-long stagnation and deflation. The government’s inability to scale back AI investments without causing economic disruption, coupled with shrinking consumer demand, could precipitate a protracted economic slowdown.

Is This Just a Doomer Perspective?

While these developments are complex and warrant careful analysis, it’s important to recognize that this is a speculative scenario. There are many variables at play, including technological breakthroughs, policy responses, and shifts in consumer behavior. Nonetheless, Kedrosky’s insights serve as a valuable reminder to monitor the evolving relationship between AI investment and macroeconomic stability.

Final Thoughts

The intersection of AI capex, debt markets, and macroeconomic trends presents a fascinating, if uncertain, picture of the future. Policymakers, investors, and consumers should stay informed about these developments, as they could significantly influence the trajectory of the U.S. economy in the coming years.
