Sweden’s gold, as a single cube

The holding

Sweden’s gold reserve, in proportion

Sweden's central bank holds about 126 tonnes of gold — a mid-tier holder, 31th of the 38 nations the World Gold Council tracks. That is a number most people cannot picture, so picture this instead: gathered into one solid block, every bar of it would form a cube roughly 1.9 m on each side — about the height of a person. Gold is so dense (19.32 grams per cubic centimetre, about two and a half times the density of iron) that Sweden's entire reserve, worth approximately $17 billion, would occupy only about 7 cubic meters.

Gold makes up 24.8% of Sweden's official reserves — a measured gold share, with the bulk of reserves held in foreign currencies. Measured against the world's monetary gold, that block is about 0.3% of all the bullion held by every central bank and treasury on the planet. Sweden sits in Western Europe, where deep, long-standing reserves are the rule.

The metal is held at Sveriges Riksbank — most held abroad. In recent years the holding has been held steady — neither bought nor sold in any size — a quiet vote of confidence in gold's role as a permanent reserve asset. Whether a reserve is growing or steady, its physical footprint barely changes: even doubling Sweden's gold would only widen the cube by about a quarter — the defining paradox of the metal is that staggering value keeps collapsing into a remarkably small space.

It is worth holding the comparison in mind. The largest reserve on Earth, the United States', is a cube only 7.5 m per side; all the gold ever mined in human history fits inside a cube about 22 m per side — the size of a seven-story building. Sweden's share of that 6,000-year inheritance is the block you see above.
