Why Central Banks Are Buying Gold and What It Means for the US Dollar

Central banks around the world have been adding large amounts of gold to their official reserves, marking a notable shift in how nations store their wealth. By the end of 2025, gold made up about 27 percent of total central bank reserves, up from roughly 20 percent a year earlier. Over the same period, the share held in US government bonds (called US Treasury securities) fell to about 22 percent from 25 percent. This means that, for the first time in recent memory, central banks collectively held more value in gold than in US debt. The rise partly reflects a higher gold price, but it also reflects deliberate buying as countries try to spread their risk across different kinds of assets.

A central reason behind this trend is geopolitical caution. Reserves are the foreign assets a country keeps to back its currency and settle international payments. Holding US Treasury bonds has long been the default choice because the US dollar is the world's main reserve currency, the currency most nations use for trade and savings. But nations worried about strained ties with the United States, the large US budget deficit (running near 6 percent of America's total output), and the risk of financial sanctions have started preferring gold, an asset that carries no national label and cannot be frozen by another government. Countries that have faced US sanctions, as well as those near conflict zones, have led the buying.

The latest data show clear leaders in this gold rush. Poland bought roughly 100 metric tonnes of gold in 2025, followed by Kazakhstan, Brazil, China and Turkey. Measured from 2022, when Russia's invasion of Ukraine triggered wide sanctions, China added about 350 tonnes, Poland about 320 tonnes, Turkey about 220 tonnes and India about 130 tonnes. Interestingly, a major private buyer also appeared: a large stablecoin issuer (a company that runs a cryptocurrency tied to the dollar's value) bought over 100 tonnes, hinting that crypto-linked assets are emerging as another possible alternative for cross-border transactions.

This is not the first time the world has lost some faith in the dollar. In the late 1960s, heavy US spending on the Vietnam War and welfare programmes raised fears of inflation, and many nations swapped their dollars for gold under the Bretton Woods system, an arrangement that fixed exchange rates to the dollar, which itself could be exchanged for gold at 35 dollars an ounce. On 15 August 1971, the US ended the dollar's convertibility into gold, breaking that system. Even so, the dollar kept its leading role for decades, helped by US security guarantees to allies and by an arrangement in 1974 under which Saudi Arabia recycled its oil earnings into dollars. Analysts now argue the dollar's future depends on the US upholding the rule of law, keeping a balance of power within government, and honouring commitments to allies.

For exam preparation, this topic links the economy and international relations sections of major exams. Aspirants should understand what foreign exchange reserves are, why gold is treated as a safe-haven asset, what the Bretton Woods system was and why it ended in 1971, and how reserve-currency status is tied to trust and security alliances. India's own steady gold purchases (about 130 tonnes since 2022) and the rise of stablecoins as a payment alternative are likely points for questions on monetary policy, international finance and current affairs.
