Macroeconomic Risk-Channel Analysis
A method for judging whether a large economic disturbance (e.g. a bubble) poses macroeconomic danger by tracing it through specific transmission channels (activity, wealth, credit) and asking whether losses land inside the banking system, rather than judging by headline size or a binary "bubble/no bubble" framing.
Also known as: transmission channels, activity stop, wealth effect, credit crunch, effective gdp impact, structurally scarring, macro risk framing

Reframing the AI-bubble question from 'when will it pop' to 'what macro risk does it pose through which transmission channels,' the authors conclude today's boom is a manageable risk — its GDP-relevant scale is far smaller than headline figures suggest and its likely losses sit outside the banking system — so executives should engage with it rather than sidestep it, while watching bank credit spreads for signs that verdict changes.

- explicitAn abrupt, complete halt of AI capex spending today would be a direct ~1%-of-GDP growth headwind (the 'activity stop' channel), but a headwind of this size alone would not end a healthy US economic expansion.
- explicitA large AI-driven equity sell-off could trigger a 'wealth effect' — rising savings rates and diminished consumer spending — because equities now account for nearly 30% of household wealth, up 10 percentage points from a decade ago.
- explicitA 'credit crunch' channel is possible if souring AI-related debt leaves large enough losses on creditors' balance sheets that they curtail lending elsewhere in the economy.
