When Nixon closed the gold window in 1971, he paved the way for infinite dollar debasement, and the U.S. and the rest of the world have been paying for it ever since. From Michael Maharrey at schiffgold.com:
Fifty-one years ago this week, President Richard Nixon slammed shut the “gold window” and eliminated the last vestige of the gold standard.
Nixon ordered Treasury Secretary John Connally to uncouple gold from its fixed $35 price and suspended the ability of foreign banks to directly exchange dollars for gold. During a national television address, on Aug. 15, 1971, Nixon promised the action would be temporary in order to “defend the dollar against the speculators,” but this turned out to be a lie. The president’s move permanently and completely severed the dollar from gold and turned it into a pure fiat currency.
The First Steps Toward Fiat
Nixon’s order was the end of a path off the gold standard that started during President Franklin D. Roosevelt’s administration. June 5, 1933, marked the beginning of a slow death of the dollar when Congress enacted a joint resolution erasing the right of creditors in the United States to demand payment in gold. The move was the culmination of other actions taken by Roosevelt that year.
In March 1933, the president prohibited banks from paying out or exporting gold, and in April of that same year, Roosevelt signed Executive Order 6102. It was touted as a measure to stop hoarding, but was, in reality, a massive confiscation scheme. The order required private citizens, partnerships, associations and corporations to turn in all but small amounts of gold to the Federal Reserve at an exchange rate of $20.67 per ounce. In 1934, the government’s fixed price for gold was increased to $35 per ounce. This effectively increased the value of gold on the Federal Reserve’s balance sheet by 69%.
