Pegged interest rates = hyperinflation?

Another data point for pegged interest rates leading to the hyperinflation solution from Brad DeLong. I didn't know that Weimar Germany had pegged interest rates.


  1. Mark Sadowski posted in the comments (somewhere) a table showing this one time. If I recall correctly after hyperinflation was well underway, there was a comical partial raising of the rates for a brief period: comical because it was relatively so small compared to how far out of control inflation was at that point. It's not apparent in your plot here, so perhaps that was a very brief transition period before raising rates more substantially.

    1. Hi Tom,

      I think it depends on the particular rate. This is an 'official rate', but some other rate might be relevant.

    2. Here's Mark's table:

      I love how they raised the rate 0.1% (all the way up to 5.1%) once YoY inflation had reached 603.5%

Also, try to avoid the use of dollar signs as they interfere with my setup of mathjax. I left it set up that way because I think this is funny for an economics blog. You can use € or £ instead.
