The link below describes what happened in Weimar Republic from 1919 to 1923. There was a period of deflation that began in early 1920, the Mark strengthened, then price inflation began going up from the April 1921 level of 6% and began its climb into eventual hyperinflation in 1923.

Interestingly enough, and maybe not related at all, there was a large Coronal Mass Ejection at the inflection point where deflation started to reverse.

There was a panic in 1857 prior to the September 1859 Carrington event. The 1844 Bank Charter act gave the Bank of England exclusivity (monopoly) in issuance of paper banknotes to the detriment of other domestic banks which were prohibited from doing so. It was inflationary in that bank credit was issued and the PM reserve requirement was sometimes waived. In the US the gold rush of 1849 had begun to peter out and the diminished gold flow was inadequate to supply growing demand for capital, largely to build railroads and telegraphs (the high tech of its day) under a PM reserve requirement. The breakout of war delighted the bankers who were given a green light to provide credit and fiat to fund the conflict.
In March 1989 there was another significant solar storm and subsequent to that a recession condition in the US from 1990 to 1993. The Federal Reserve Fed Funds rate was at a peak of 9.85% in March of 89 and began a decline that hit a trough in November of 1992 of 3.09%. It has remained at around 5% or lower since then. The correlation, if any, solar storm coincides with easing of interest rates which increases lending which increases fiat money supply.
