Normally, a weaker dollar means higher commodity prices.  Potentially ominous for them to be going in opposite directions.

In this case, the weaker Dollar could be signalling a couple of things.

1. Global Loss of confidence in US leadership and policies 

2. Loose cannon US Fed is going to have to reverse course again and start aggressively CUTTING interest rates to avoid an economic collapse from our catastrophically awful fake green energy, fiscal and war in Ukraine policies in tandem with the damage from higher interest rates to consumers and banks.
