I stumbled upon a few interesting reads about the end of the Bretton Woods system in August 1971. In those years there was a lot of monetary turmoil, just like now. Before 1971 the US dollar was pegged to gold, and foreign countries held dollars in reserve because the US had promised they were “as good as gold”. The dollar came under pressure because the US money supply grew, but they insisted to keep the gold price at $35. Many European countries were redeeming their dollars for gold, because the dollar was overvalued relative to gold.
