Three Bubbles, One Liquidity Problem: The Market Is Running Out Of Room

U.S. fiscal deficits, record market leverage and the AI capital-spending boom are increasingly competing for the same marginal dollar of funding. With debt-to-GDP near 122% and a much larger share of Treasury debt exposed to market pricing, the U.S. has far less room to absorb future shocks than in GFC. Equity markets are operating with historically high leverage, extraordinary derivatives activity and low volatility, making them increasingly vulnerable to even a modest tightening in financial conditions. The AI boom is becoming a funding problem as hyperscalers commit enormous amounts of capital while chipmakers and memory producers depend on those expenditures to sustain unusually high margins. The real risk is that these pressures do not remain independent, as a fiscal shock could raise yields, trigger deleveraging, tighten funding conditions and ultimately undermine the economics supporting the AI investment cycle.

We believe that the market is approaching a point where three seemingly separate extremes ( U.S. fiscal deficits, financial-market leverage, and the AI capital-spending boom) begin to compete
