The last opportunity for devaluing the dollar took place in August 1971, when the dollar was still pegged at 1/35th of an ounce of gold.

 

Nixon took the advice of Milton Friedman and made the worst mistake in history; Nixon did not devalue the dollar as he should have done, but simply took the US off the gold standard, such as it was, and thence forth the US refused to redeem dollars held by Central Banks around the world at any price.

 

Since August 15, 1971, the dollar can no longer be devalued.

Since the dollar is the reserve currency of all Central Banks in the world, all other currencies – the euro included – are only derivatives of the dollar. The proof of this statement is that the value of each and every currency in the world is calculated in dollars,

The world’s currencies are devalued or revalued against the dollar in the world’s currency markets every day of the year.
