300 years of interest rates

In this post I just did a bit of educated guessing about where the monetary regime breaks should go over the past 300+ years in the UK (time series from here). Turns out all but one (in 1790) roughly correspond to points where interest rates changed from being/not being "pegged" (see here, here, and here):

I plan on doing a future post where I see if I can make this into a more scientific proposition rather than some vague empirical eyeballing ...
