Excellent summary of the historical cycle. Note particularly how long each reserve currency cycle lasted. Quite interesting that despite spanning almost 600 years, with different rates of technological advances etc. their time as the reserve currency ranged between 80 and 110 years. The US time is just about over.
“Since 1450 there have been six major world reserve currency periods. Portugal (1450–1530), Spain (1530–1640), Netherlands (1640–1720), France (1720–1815), Great Britain (1815–1920), and the United States from 1921 to today. It should be called the banker harvest cycle.” https://goldseek.com/article/take-look-around-signs-dying-empire-will-villagers-resist-or-just-shoot-each-other
