IMF Models Three AI Scenarios: Bust Case Could Cut 2028 Global Growth by 1.3 Points, $9T US Buildout
shashib · x · 2026-10-17
Analyzing the IMF's three AI scenarios (via WSJ reporting):
- Optimistic case: productivity gains with contained inflation. Middle case: buildout hits chip supply limits, so inflation and rates rise before productivity arrives. Bust case: up to 1.3 percentage points shaved off global growth in 2028. The IMF didn't say which it deems most likely.
- Key numbers: 3.1% global growth forecast for 2026; $9T US AI buildout through 2032; +0.5 pt annual world growth in the good-adoption case.
- Core argument: every scenario assumes payoff lags spending. Georgieva frames it as diffusion timing — people overestimate short-term gains and underestimate long-term ones. Practical takeaway for buyers: vendors funded from operating cash flow can wait out slow payoffs; check which kind holds your contract.
