Central banks keep buying gold

A trader buys when they expect a price to rise. A reserve manager buys because of what the asset is. The distinction is usually academic and becomes visible when the price falls and the buying continues, which is what has happened this year.

Official sector purchases have been substantial and sustained. Industry figures record net central bank buying of 289 tonnes in the second quarter, the strongest second quarter in the series and a sharp increase on the same period last year.

The motivation reserve managers give is not about return. Survey work reports a large majority expecting the dollar's share of global reserves to decline over the next five years, and a record share of institutions intending to add gold themselves.

That is a portfolio construction argument rather than a market call. A reserve held in another country's currency is a claim on that country's financial system, and gold is the only large reserve asset that is nobody's liability.

The events that made that abstraction concrete were the freezing of reserves in recent geopolitical episodes. A reserve that can be immobilised by the issuer is a different instrument from one held in a vault, and reserve managers now price that difference.

The buying is also widely distributed rather than concentrated in one or two large actors, which is what makes it durable. A single buyer can stop; a broad shift in allocation policy across many institutions does not reverse on a quarter's price action.

For the market the consequence is a persistent, price-insensitive bid. Central banks do not chase and do not panic, and their presence changes the shape of drawdowns without preventing them.

That is not a reason for anyone else to buy. A reserve manager's objective function has nothing in common with a private investor's: they are not seeking a return, they are seeking an asset that survives a scenario in which their other reserves do not.

The scale is worth keeping in proportion. Even at these rates the flows are small against the total stock of gold above ground, and they matter for price formation at the margin rather than dominating it.

What they signal is more interesting than what they do. A steady rotation out of currency reserves toward a neutral asset is a statement about the international system, made in the one language reserve managers are obliged to be honest in.
