The number of ounces of gold required to purchase a loaf of bread, traced from the early 20th century to today. The values are tiny — fractions of a thousandth of an ounce — but the pattern across a century is striking: the loaf of bread has cost approximately the same amount of gold for over a hundred years, while costing many times more in dollars. Bread is one of the cleanest tests of gold’s purchasing-power durability across long time horizons.
Analyst's Note
Bread is a useful benchmark precisely because it is a real, productive, tangible good with relatively stable input costs (wheat, water, energy, labor) over long periods. The slight downward trend in gold-priced bread reflects genuine productivity gains in agriculture and food production, not currency effects. The much larger downward variation in dollar-priced bread reflects currency debasement layered on top. For the analytical investor, the bread-in-gold chart is the most honest answer to ‘has gold preserved purchasing power?’ The answer is unambiguous: yes, with productivity-driven improvement. The chart is also a useful counter to the argument that gold is ‘just a commodity’ — commodities don’t preserve purchasing power across centuries; gold does.
