Trap of correlation. Trap of fundamentals.
If the dollar weakens, buy gold. Are you still believing such a superstition?
But if you trade by swallowing that claim whole, you’ll face painful results.
When you start learning about gold, you’ll inevitably encounter this explanation. “Gold is inversely correlated with the dollar. If the dollar falls, gold rises.” Some people enter trades with the idea, “Today the dollar is weak, so gold is a buy.”
Let me state the conclusion first.The inverse correlation between the dollar and gold does not always hold.If you trade by assuming this relationship is an absolute law, you will incur large losses the moment the correlation breaks.
Correlation is a reference. But believing it at a superstition level as “it will always move this way” is dangerous. This time, I will explain how to correctly understand the relationship between the dollar and gold.
Inverse correlation is a “trend,” not a “law”
Indeed, there is often a tendency for the dollar and gold to move in opposite directions. Since gold is traded in dollars, when the dollar’s value falls, gold’s price tends to rise relatively.
But this isa “tendency,” not an absolute rule.In real markets, the dollar and gold can move in the same direction as well. It’s not uncommon for both to rise or both to fall.
Correlation strengthens or weakens over time, and can even reverse at times. The simple idea that “because dollars are weak, gold must rise” does not hold in many situations. If you believe in inverse correlation without knowing this, the market will disappoint you.
・The inverse correlation is a trend, not a guaranteed rule
・There are also phases where they move in the same direction
・The strength of the correlation varies over time
・Multiple factors interact, so it cannot be oversimplified
It is dangerous to mechanically apply “dollar weakness = buy gold.”
