If you track the price of gold, you will notice that traders are obsessed with the US Federal Reserve (the Fed). Every time the Fed announces a change to interest rates, the gold market violently reacts. Why are interest rates the most powerful gravitational force acting on gold?
The Flaw of Gold: No Yield
If you buy an Apple stock, it pays you a dividend. If you put money in a savings account, it pays you interest. If you buy a government bond, it pays you a coupon.
If you buy a bar of gold and lock it in a safe, five years later, it is still just a bar of gold. It produces nothing. It pays zero interest.
Opportunity Cost
In finance, "opportunity cost" is what you lose by choosing one investment over another.
- When Interest Rates are HIGH: Let's say the government raises interest rates, and suddenly you can get a 5.5% guaranteed, risk-free return simply by holding a US Treasury Bond. Large institutional investors will dump their zero-yield gold and buy the bonds instead to collect the high interest. As billions of dollars flow out of gold, the price of gold crashes.
- When Interest Rates are LOW: If the government cuts interest rates to near 0%, holding cash in a bank actually loses money due to inflation. Because bonds and cash no longer pay a yield, the "penalty" for holding zero-yield gold disappears. Investors rush back into gold to protect their wealth from inflation, and the price of gold skyrockets.
The Modern Paradox
Historically, high interest rates always crushed gold. However, in recent years, we have seen gold prices rise *despite* high interest rates. This paradox occurs when investors fear that the high interest rates will cause a severe recession or banking crisis. In that scenario, the fear of systemic collapse overrides the desire for yield, and gold surges purely on its "Safe Haven" status.
