An analysis of the Reichmuth Lecture at the University of Zurich: Prof. Carmen Reinhart (Harvard Kennedy School, former World Bank Chief Economist) on public debt, the AI bubble and the dollar — and why Switzerland is the counter-model.

It's not high debt alone that is the problem, but the return to normal interest rates — it turns a bearable burden into a growing budget line.

Reinhart is not an AI pessimist — it's enough that not everyone is a winner. The risk sits in leverage and opacity, not in the technology itself.
Reinhart: in 2008 China was the world's growth engine, propping things up with stimulus. That buffer is gone today — the world economy starts from a shakier base.
Especially relevant for Japan and Italy — a large part of the ECB's bond buying aimed precisely at defusing this loop at Italian banks. And it touches central-bank independence.
All the historical markers show the dollar still playing its anchor role. Even China lends abroad in dollars, not yuan. Dornbusch: you only go to a party when you know you can leave.
The higher the public debt, the greater the pressure on the central bank to keep rates low — that is what Reinhart means by independence threatened "de facto."
Stay informed.
