A strong argument suggests that robust economic spending combined with weak labor growth points to higher productivity, potentially from AI. Because productivity gains are disinflationary over the long term, this could give the Fed justification to lower interest rates now without worrying as much about current inflation levels.

Typically, accelerating economic growth leads to higher inflation expectations and bond yields. The current trend of falling break-evens alongside positive growth data is unusual. The residual factor explaining this divergence is a market-wide bet that AI will unleash a massive, disinflationary productivity wave.

Beyond simple productivity gains, AI will eliminate the need for entire service-based transactions, such as paying for basic legal documents or second medical opinions. This substitution of paid services with free AI output can act as a direct deflationary headwind, a counterintuitive effect to the typical AI-fueled growth narrative.

The ability of Western governments to manage their enormous public debt levels is now implicitly dependent on the hope that AI will generate a massive, sustained productivity boom. If AI fails to deliver this unprecedented growth, a widespread fiscal crisis becomes a serious risk.

Despite significant geopolitical risks, an equally plausible optimistic scenario exists. Transformative general platform technologies like AGI, quantum computing, and synthetic biology are nearing commercial scale, potentially creating a productivity boom that could offset debt headwinds and turbocharge the economy.

In a high-impact AI scenario, massive productivity growth leads to gluts of goods and services. This causes prices to collapse, creating massive deflation. This deflation acts as a universal pay raise, dramatically increasing everyone's real wealth and purchasing power.

The US can grow its way out of its mounting fiscal problems through AI-driven productivity. This creates real growth without wage inflation, expands the corporate tax base, and offsets a poor demographic outlook. This is the most viable path for the US to avoid a fiscal cliff.

As AI gets exponentially smarter, it will solve major problems in power, chip efficiency, and labor, driving down costs across the economy. This extreme efficiency creates a powerful deflationary force, which is a greater long-term macroeconomic risk than the current AI investment bubble popping.

A rapid, broad adoption of AI could significantly boost productivity, leading to faster real GDP growth while simultaneously causing disinflation. This supply-side-driven scenario would present a puzzle for the Fed, potentially allowing it to lower interest rates to normalize policy even amid a strong economy.
