Central Banks and Gold: Why Official Reserves Still Hold Metal

Gold stopped anchoring the international monetary system more than half a century ago, yet central banks still hold tens of thousands of tonnes of it, and many have been adding more. Why official institutions hold a metal that pays no interest, and how they swung from selling to buying, explains one of the more durable forces in the gold market.

Why a central bank holds gold at all

Reserves exist for a crisis: to defend a currency, pay for imports or reassure creditors. Most are held in foreign government bonds, mainly US Treasuries, because they are liquid and pay interest. Gold plays a different role.

• No counterparty. A bar in a vault is not someone else’s liability. It cannot be defaulted on or devalued by another government’s policy.
• Sanctions resilience. Bonds and deposits held abroad can be frozen. Gold stored at home is harder to block, a point that gained weight after Western governments froze a large share of Russia’s foreign reserves in 2022.
• Diversification. Gold has tended to behave differently from the dollar and from bonds, which can stabilize the total value of a reserve portfolio.
• Credibility and history. Large gold holdings still signal financial strength, and many of the biggest stockpiles are legacies of the gold standard era.

The trade-off is cost: gold yields nothing, must be stored and insured, and can swing sharply in price. Hence its share of reserves varies widely between countries.

From Bretton Woods to the end of convertibility

Under the Bretton Woods system set up after the Second World War, other currencies were pegged to the dollar, and the dollar was convertible into gold for foreign official holders at $35 per ounce. As US deficits grew in the 1960s, foreign central banks accumulated more dollars than the US gold stock could credibly back, and some began converting.

On August 15, 1971, President Nixon suspended the dollar’s convertibility into gold. Within a few years major currencies were floating, and gold became a reserve asset with a market price rather than the official yardstick of value. Central banks kept most of their metal, but the reason for holding it changed from monetary rule to portfolio choice.

The selling era and the Central Bank Gold Agreements

Through the 1980s and 1990s, many European central banks viewed gold as an outdated, non-earning asset. Several sold, and the expectation of more sales weighed on prices. The United Kingdom’s sales between 1999 and 2002, announced in advance and conducted by auction near the bottom of the market, are still cited as an example of poorly timed disposal.

To prevent uncoordinated selling from collapsing the price, a group of European central banks signed the first Central Bank Gold Agreement in September 1999. It capped their combined annual sales at 400 tonnes for five years and limited new leasing. Further agreements followed in 2004, 2009 and 2014. Over time the signatories sold less and less than the caps allowed, and the arrangement eventually lapsed because there was no longer meaningful selling to coordinate.

The shift to net buying

Around 2010, the official sector as a whole turned from net seller to net buyer, and it has stayed on the buying side since. Several things drove the change:

Emerging-market central banks have done most of the buying. Russia added steadily for years before 2022. China’s central bank has reported purchases in several distinct waves, sometimes after long gaps without reported changes. India, Turkey and Poland have also been prominent buyers at various points, and a number of smaller banks in Central Asia, the Middle East and Central Europe have added metal. Some purchases are disclosed late, so annual totals are revised estimates.

The largest holders are mostly still Western: the United States reports about 8,133 tonnes, and Germany, Italy and France also hold very large stocks, largely accumulated decades ago.

The IMF, swaps and leasing

The International Monetary Fund is one of the largest single holders of gold, a legacy of the era when member quotas were partly paid in gold. Its articles restrict how it can use the metal, and sales require broad approval among its members. The Fund did carry out a limited, pre-announced sale around 2009–2010, mainly to official buyers, to fund its operations and concessional lending.

Central banks also put gold to work without selling it:

• Leasing: lending gold to bullion banks for a small fee. The banks typically sell the metal and later buy it back to return it. Leasing was popular in the 1990s and added supply to the market at the time.
• Swaps: exchanging gold for currency for a set period, with an agreement to reverse the deal. The Bank for International Settlements is a frequent counterparty. Swaps let a central bank raise liquidity without parting with its metal permanently.

Because these deals are not always disclosed in detail, it is hard to know how much metal sits unencumbered in official vaults.

What official buying means for price

Official purchases tend to be price-insensitive and long-term: a central bank diversifying reserves is not trying to time the next rally. That steady buying can help put a floor under the market when investment demand weakens.

It does not guarantee rising prices. Official purchases are one demand component alongside jewelry, technology, bar and coin buying and exchange-traded funds, all covered in our guide to what moves gold prices. Investment flows in Western markets, driven by interest rates and monetary policy, can still dominate in the short run. And a change of policy, or a central bank selling to support its currency, can reverse the picture.

Key points

• Central banks hold gold for safety, diversification and independence from other governments, not for yield.
• The end of dollar convertibility in August 1971 turned gold from a monetary anchor into a reserve asset with a floating price.
• European sales in the 1990s led to the Central Bank Gold Agreements, first signed in 1999.
• Since around 2010 the official sector has been a net buyer, led by emerging-market banks.
• Steady official demand can support prices, but it is one factor among several. For more context, see the monetary policy section.
