Opportunity cost in gold trading
Opportunity cost is the return given up by holding gold, which pays no interest, instead of cash or bonds; higher real rates raise it, lower rates reduce it.
Also called Cost of carry for gold, Non-yielding asset
Opportunity cost is the value of the best alternative you give up when you choose one option. For gold, the alternative is usually a safe interest-bearing asset such as Treasury bills or bonds. Because gold pays no interest or dividend, its opportunity cost rises when interest rates rise.
How it applies to gold trading
This is the main reason gold reacts to interest rates. When short-term Treasury bills pay 5%, holding gold costs 5% a year in lost interest, and investors demand a reason to accept that, such as inflation fears or crisis protection. When real rates are near zero or negative, holding gold costs little in real terms, and it competes easily with bonds.
For leveraged XAUUSD positions, opportunity cost shows up directly in the swap. Longs pay a financing charge linked to dollar interest rates, which is why swaps on long gold positions grew more expensive during rate-hiking cycles.
Worked example
Example (hypothetical numbers): an investor holds $100,000 in gold for a year while Treasury bills yield 4.5%. The interest forgone is $4,500. Gold must rise by more than 4.5% to beat the bills. If bills paid 0.5%, the hurdle would be only $500.
A common mistake
Comparing gold’s price return with a stock index or bond return and forgetting the income the other asset paid.

Frequently asked questions
Why is gold called a non-yielding asset?
Because holding it pays no interest or dividends. Its return comes only from price changes.
How do interest rates affect the cost of holding gold?
Higher rates raise the income you give up by holding gold instead of cash or bonds, and they raise the swap on leveraged long positions.
Does the opportunity cost of gold matter for short-term traders?
Less than for investors, but it appears in the swap you pay on leveraged long positions and in how gold reacts to changes in rate expectations.
