Everlasting credit, the long view
From historical chart specialists Global Financial Data — the yield on perpetual Consols versus the stock of UK sovereign debt…all the way back to 1742. Click to view….MORE (chart, discussion)Unfortunately no discussion of the convexity of an instrument that has this kind of duration.

...It was while skimming the GFD list that this popped out (remember this is inflation adjusted!):
Best and Worst Investment Periods in Germany
What
were the best and worst months in the history of the German stock
market? The most obvious factor is the importance of the hyperinflation
of 1922 through 1924. The data have been calculated in real returns,
adjusting for inflation during the hyperinflation of the 1920s, and as
you can see, the hyperinflation provided investors with both strong
returns and dismal returns, though more of the latter. The dates outside
of the 1920s which registered as among the best and the worst are
conspicuous, October 1949 for the stabilization of the German financial
system, November 1918 for the end of World War I, September 1931 in the
middle of the collapse of the German economy, and of course, October
1987.
