How much is the correlation between the rise and fall of the US dollar index and the exchange rate of the US dollar against RMB? Or is it basically irrelevant?
The dollar index is an indicator of the weighted comprehensive evaluation of the dollar against many currencies, and they certainly have some correlation. But at present, the rise and fall of the dollar index is mainly related to the exchange rate of the dollar against the euro, the pound and the yen, and the weight of the dollar against the renminbi is very small.
