Ferguson notes that while AI may boost productivity, "the demand for investment starts to go up, which also pushes up interest rates." Investors often assume AI is purely deflationary (allowing rate cuts). Ferguson introduces the Second-Order effect: The massive CapEx required for AI creates a demand for capital, which raises the cost of money (rates). This means the AI boom can coexist with—and actually cause—higher interest rates, rather than solving them. WATCH. Be careful assuming AI will trigger a low-rate environment; the investment phase is capital-intensive and rate-supportive. If AI fails to deliver productivity gains quickly, the investment demand could dry up, altering the rate dynamic.
