Thailand’s gold, as a single cube

The holding

Thailand’s gold reserve, in proportion

Thailand's central bank holds about 235 tonnes of gold — a mid-tier holder, 21th 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 2.3 m on each side — taller than a basketball hoop. Gold is so dense (19.32 grams per cubic centimetre, about two and a half times the density of iron) that Thailand's entire reserve, worth approximately $31 billion, would occupy only about 12 cubic meters.

Gold makes up 12.4% of Thailand'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 0.6% of all the bullion held by every central bank and treasury on the planet. Thailand sits in Asia, the center of gravity for twenty-first-century gold accumulation.

The metal is held at Bank of Thailand, Bangkok. In recent years Thailand has been a net buyer, steadily adding to the pile — part of the broad return to gold among emerging-market and reserve-diversifying central banks. Whether a reserve is growing or steady, its physical footprint barely changes: even doubling Thailand'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. Thailand's share of that 6,000-year inheritance is the block you see above.
