My neighbor brought to my attention a very interesting chart … the interest rates history in the USA since 1790. The chart is for the rate on 10-year Treasury bonds. A large version is available in the linked web page.
I wonder how creditable the data is for some of those ancient years, but it should be accurate for the years since the “Fed” was created in 1913. The history is interesting and rather startling in some spots, both the height of the peak in the 1980-era, when the Fed” was fighting rather severe inflation, and the very recent “Quantitative Easing” conducted by the Fed to stimulate the US economy.
That interest rates could be forced through the open markets to near-zero is simply amazing.
