Intermarket context
The idea
Gold is commonly quoted in US dollars, and its opportunity cost is often discussed alongside interest rates adjusted for inflation expectations. These relationships vary over time. A dollar rise or a real-yield rise does not impose a fixed move on gold because positioning, risk demand and other flows can dominate.
A worked example
Two sessions with a stronger dollar can produce different gold outcomes. A historical correlation summarizes a sample; it is not a price equation.
Try it yourself
Compare aligned daily percentage changes for gold and a reference series over several windows.
A mistake to avoid
Treating an inverse relationship as permanent or sufficient for a leveraged trade.
