An inflation hedge is an asset expected to hold or grow its real value when prices rise, protecting purchasing power as inflation erodes money. Gold, certain commodities, and inflation-linked bonds are often used for this purpose.
An asset hedges inflation when its price tends to climb alongside the general price level. Gold is a common choice because its supply grows slowly and it is priced globally, so when a currency loses value it often takes more of that currency to buy the same ounce of gold.
The opposite is a nominal asset such as cash or a fixed-rate deposit, whose face value stays the same while inflation quietly reduces what it can buy. Holding cash feels safe but loses real value in an inflationary period, the very risk a hedge is meant to offset.
You keep USD 2,350 in cash while inflation runs at 8 percent for a year.
The real value of that cash falls: USD 2,350 ÷ 1.08 ≈ USD 2,176 in today's buying power
Had you held an inflation hedge that rose with prices, it would better protect what your money can buy. These figures are illustrative.
