You are right.
The US used to think that pricing commodities in USD will save US from high commodity prices, but what we are seeing in Canada and Australia (2 commodity countries) are that commodity prices are now breaking away from running in tandem with USD.
Remember what happened last year when oil prices are high, US consumers were suffering from record prices while the high AUD saved Aus consumers from super high prices.
It is the same as Gold prices. If there is a loss in confidence in the Australian economy, the gold price and AUD will move independently.
I just met my tax accountant today, I'm going to get about 90% of my tax refund Jealous rite?
Aud dollar continues to gain against USD. Jealous rite?
Gov give us up to $24k grant to buy new property (not HDB hor), jealous rite?
