Armstrong again exhibits that he has the most thorough and accurate databases of world history as follows. Armstrong's more accurate chart imparts a different conclusion, which is that interest rates are on an inexorable decline.
I guess different observers can interpret lines on a chart in different ways but I pretty much see the same conclusion. Both show several occasional outlier peaks against a longer term trend of rate declines.
I found the behavior of the long-term/short-term spread over the past few hundred years to be interesting on this new chart. Not something I'd seen plotted before.
The government output/GDP chart is also interesting. I posit that this is reaching (or may have already exceeded) an absolute long term limit. The tend can't continue.
