How it'd likely start is we print to cover a shortfall in debt. Maybe it's 500B, maybe it's 1T.

And we could do that for a bit before entering hyperinflation.

Hyperinflation would start when the TBill rate ends up exploding because people start pricing in dollar printing into the bond rates.

And, as I said, it would be something that would cause countries to start looking at ditching the dollar.

It's not great fiscal policy, but it is something that the US can currently uniquely do and enjoy without the absolute risk of hyperinflation.
