How Central Banks Trade Gold: Inside the Allocated Market

Central banks collectively hold over 35,000 tonnes of gold — more than 17% of all gold ever mined. Understanding how they buy, sell, store, and lend gold is essential context for anyone in institutional finance.

Central banks are the single largest holders of gold in the world, collectively accounting for approximately 35,600 tonnes as of early 2026 — roughly 17% of all gold ever mined in human history. Their behaviour in the gold market is a significant price driver, a barometer of confidence in the international monetary system, and a topic that every finance professional working with institutional clients needs to understand. ## Why central banks hold gold The official rationale for central bank gold holdings has evolved over the past 25 years. In the 1990s and early 2000s, several major central banks — the UK, Switzerland, France, the Netherlands — sold substantial gold reserves on the grounds that the metal provided no yield and that foreign exchange reserves denominated in major currencies were a superior store of value. That consensus has reversed completely. The reasons are structural: gold has no counterparty risk (unlike US Treasuries, which carry credit risk to the US government), it is not subject to sanctions (a consideration that became viscerally real when Western governments froze Russia's dollar and euro reserves in 2022), and it has maintained purchasing power over long periods in a way that fiat currencies have not. The gold that central banks hold is stored in three primary locations: the Bank of England, the Federal Reserve Bank of New York, and each central bank's own national vaults. The Bank of England is the world's second-largest physical custodian of gold, holding approximately 400,000 bars for over 70 central banks and international financial institutions. ## How central banks buy gold Central bank gold purchases are conducted through the OTC market, almost always in large allocated transactions. The scale of these transactions — a central bank might purchase several hundred tonnes over a year — means they cannot be executed through ordinary market channels without material price impact. In practice, central banks work with a small number of approved bullion banks who act as agents, aggregating supply from refiners, miners, and other market participants over time. The transactions are settled in the Bank of England's clearing system, with allocated bars changing custody records without physical movement in most cases. The IMF's data on central bank gold holdings is published monthly, but with a lag. Some central banks — China being the most notable — are widely believed to hold significantly more gold than their official IMF reports indicate. Analysing the gap between reported holdings and inferred purchases from trade data is a research discipline in itself. ## Gold lending and the lease market Central banks that hold gold in custody at the Bank of England or the Fed can generate a return on their gold holdings by lending it into the market. The gold lease market is facilitated primarily by the major bullion banks, who borrow gold from central banks (paying a lease rate, typically 0.1%–1.5% per year), sell it spot, invest the proceeds in higher-yielding assets, and return the gold at maturity. This gold-carry trade was enormous in the late 1990s and early 2000s, when lease rates were low and dollar yields were high. It contracted significantly after the 2008 financial crisis and has remained modest since. But understanding it is important for interpreting lease rate data, which is a useful signal for physical gold market conditions. The Central Bank Gold Agreement (CBGA), which for many years limited the aggregate gold sales by European central banks to 400-500 tonnes per year, expired in 2019 and was not renewed. The shift in central bank behaviour from net sellers to net buyers had already rendered it largely irrelevant. ## What this means for your analysis Understanding central bank gold flows matters for financial professionals in several practical contexts. For macro strategists, tracking IMF data and BIS quarterly statistics provides insight into official sector demand that is a significant component of total gold demand. For portfolio managers building emerging market exposure, understanding which central banks are building reserves — and why — provides context for understanding their monetary policy decisions more broadly. For relationship managers at institutions that service sovereign wealth funds or central banks, this knowledge is table stakes for credible advisory.
