I am strugling with your first sentence.
I think you are saying that the dollar, a fiat currency, has made all time highs in gold.
Do you mean that the price of gold has declined in relation to the dollar? But that other currencies have declined in relation to the dollar and gold?
If so, then I suppose the value of the dollar is increasing. Flight to quality. Happens sometimes at times of heightened risk when other assets are expected to perform poorly in the near term.
