Weimar inflation, while it went especially nonsensical in 1923, it went went on for many years, in fits and starts, and at times even showed signs of leveling off or moderating before starting up again. It had the effect of people thinking that maybe the government had things under control. Lasted far longer than a few months.
It DID show up out of the blue e.g. “like lightning it struck... it was terrible..” As one man recounted.
The final Weimar hyperinflation lasted only a few months after years of up and down inflation and economic screwing around. The final and famous smashup lasted only three months or so. You can look at charts or you can read “When Money Dies”. You call 1923 “nonsensical” but it was the realization by the population that they were truly screwed that created the famous scenes with which we are all familiar. It made perfect sense for the people at the time.
Weimar history has years of dithering about followed by sudden realization and panic. It was not slow and people did not have time to do anything. What have you done?
