Does gold really protect against inflation?
Gold is famous as the classic inflation hedge, but the relationship is far more nuanced than the story goes: sometimes it protects, sometimes it doesn't, and there's a factor that matters more than inflation itself. Understanding it stops you buying gold for the wrong reason.
Where the fame comes from
Historically, gold has kept its purchasing power for centuries: an ounce bought a good suit a hundred years ago and still does today. That permanence, versus currencies that lose value over time, is the origin of its inflation-hedge reputation.
The nuance: it doesn't work short term
Long term (decades) gold keeps value, but short and medium term its price can fall even as inflation rises. In 2022, with inflation soaring, gold was flat or down for months. Why? Because another factor weighed more.
The ruling factor: real rates
Gold's price depends above all on real interest rates (nominal rates minus inflation). When real rates rise, gold suffers (it pays no interest and other assets do); when they fall or turn negative, gold shines. Inflation matters, but through how it makes central banks react with rates.
High inflation + high rates = weak gold
Here's the key that confuses many: if there's high inflation but the central bank hikes rates hard to fight it, real rates rise and gold can fall despite inflation. Only when inflation outpaces the rate hikes (negative real rates) does gold truly surge.
What it means for you
Don't buy gold simply because "there's inflation". Look at real rates: if they're falling or negative, the wind favours gold; if they're rising hard, against it. Inflation is just one piece; real rates are the engine.
Where to start
Get used to checking two things before trading gold: what inflation is doing and what interest rates are doing. The gap between them (the real rate) will tell you more about gold than any "inflation rises" headline.
