Yes, but only because it is the best of the fiat currencies.
Since all currencies are fiat currencies, the dollar is the best currency right now, period.
After Nixon separated the dollar from gold, the dollar became counter-cyclical to the gold.
Since gold is traded globally, this isn't surprising. Most internationally traded goods will become cheaper as the dollar strengthens since a stronger dollar has more purchasing power. The stronger the dollar is to the Chinese yuan the cheaper those Chinese imports will be for Americans. The price of gold is also set based on what people in other countries will pay for it, and if their currency is weaker than the dollar then the price of gold will go down with respect to the dollar.
The dollar can't even determine the value of itself.
Go to a grocery store. They have little signs everywhere that tell you what the value of the dollar is.
