India’s gold, as a single cube

The holding

India’s gold reserve, in proportion

India's central bank holds about 881 tonnes of gold — one of the ten biggest official holders. 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 3.6 m on each side — about one storey tall. Gold is so dense (19.32 grams per cubic centimetre, about two and a half times the density of iron) that India's entire reserve, worth approximately $118 billion, would occupy only about 46 cubic meters.

Gold makes up 18.5% of India'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 2.4% of all the bullion held by every central bank and treasury on the planet. India sits in Asia, the center of gravity for twenty-first-century gold accumulation.

The metal is held at RBI vaults in India, plus BoE & BIS. In recent years India 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 India'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. India's share of that 6,000-year inheritance is the block you see above.
