For decades, U.S. Treasury bonds were the undisputed foundation of the global financial system. Central banks around the world stored vast amounts of their national wealth in Treasury securities because they were considered safe, liquid, and backed by the world’s largest economy.
That reality has now changed.
According to a new report from the European Central Bank (ECB), gold has overtaken U.S. Treasuries as the largest reserve asset held by central banks worldwide. At the end of 2025, gold represented approximately 27% of global central bank reserve assets, while U.S. Treasuries accounted for about 22%.
The shift marks one of the most significant changes in global reserve management in generations and raises important questions about confidence in government debt, the future role of gold, and the long-term position of the United States in the international financial system.
A Remarkable Change in Just a Few Years
The speed of the transition is striking.
Only one year earlier, gold represented 20% of global central bank reserves. U.S. Treasuries accounted for roughly 25%. In just twelve months, gold jumped seven percentage points while Treasuries declined three percentage points.
The ECB noted that gold’s share rose to 27% while Treasuries fell to 22%, making gold the largest reserve asset for the first time in modern history.
This was not simply the result of massive new gold purchases. A major factor was gold’s extraordinary price appreciation.
When Russia launched its invasion of Ukraine on February 24, 2022, gold traded near $1,905 per ounce. By June 2026, gold was trading around $4,555 per ounce after reaching a record high near $5,400 earlier in the year.
That represents a gain of roughly 139% in a little over four years.
As gold prices soared, the value of existing gold reserves increased dramatically. The ECB noted that if reserve assets were valued using 2023 gold prices, U.S. Treasuries would still be the largest reserve asset. Instead, the explosive increase in gold prices pushed bullion ahead.
Why Are Central Banks Buying So Much Gold?
Several powerful forces appear to be driving the trend.
Perhaps the most important catalyst was the freezing of Russian reserves after the Ukraine war began in 2022.
The United States and its allies froze a substantial portion of Russia’s foreign reserves that were held within the Western financial system. That action sent a message to governments around the world that financial assets held abroad could potentially become inaccessible during periods of geopolitical conflict.
Gold offers a unique advantage.
Unlike Treasury bonds, bank deposits, or other financial assets, physical gold stored inside a country’s own borders cannot be frozen by another government.
As the ECB explained, geopolitical concerns have become a major factor. ECB President Christine Lagarde stated, “Geopolitical tensions continue to drive strong demand for gold among central banks.”
Growing concern about America’s fiscal position has also played a role.
The United States recently surpassed $39 trillion in national debt and is adding approximately $2 trillion annually. Combined with ongoing geopolitical tensions involving Ukraine, the Middle East, and growing competition between the United States and China, many reserve managers have sought greater diversification.
Major buyers have included China, India, Turkey, Poland, Kazakhstan, and Brazil. These countries have steadily increased their gold holdings while reducing their reliance on dollar-based assets.
How Much Gold Exists in the World?
The numbers involved are staggering.
According to estimates from the World Gold Council cited in the source material, approximately 220,000 metric tons of gold have been mined throughout human history.
That equals roughly 7.07 billion troy ounces.
At today’s prices, the value of all above-ground gold is enormous:
- At $4,500 per ounce: approximately $31.8 trillion
- At $5,000 per ounce: approximately $35.4 trillion
- At $5,500 per ounce: approximately $38.9 trillion
Using current gold prices, the world’s total gold supply is worth roughly $32 trillion to $35 trillion.
That figure is remarkable when compared with other major asset classes.
The entire stock of gold ever mined is worth somewhat less than the total U.S. national debt, which now exceeds $40 trillion. It is also worth less than the entire U.S. stock market, estimated at roughly $60 trillion, and far less than the global stock market, which exceeds $120 trillion.
Does This Mean the Dollar Is Losing Its Crown?
Not necessarily.
The headlines are dramatic, but the reality is more nuanced.
Gold may have surpassed Treasuries as a reserve asset, but the U.S. dollar remains the world’s dominant reserve currency.
According to the information cited, dollar-denominated assets still account for roughly 42% of global foreign exchange reserves. International trade, commodity markets, global banking, and cross-border finance continue to operate overwhelmingly in dollars.
The ECB itself emphasized that the shift toward gold does not imply an immediate collapse in demand for U.S. government debt.
Treasuries still represent more than one-fifth of global reserves and remain one of the most liquid financial instruments in existence. The euro, often viewed as the most likely alternative to the dollar, remained unchanged at approximately 15% of global reserves.
In other words, central banks are not rushing into euros, yuan, or other currencies. Much of the diversification appears to be flowing directly into gold.
What Happens Next?
The implications for gold could be significant.
Central banks collectively own approximately 36,000 tons of gold worth roughly $5.2 trillion at current prices. Foreign official institutions currently hold about $3.9 trillion in U.S. Treasuries.
As long as central banks continue viewing gold as protection against sanctions, geopolitical instability, and rising government debt, demand for bullion is likely to remain strong.
At the same time, the ECB cautions that gold is not a perfect reserve asset. Gold pays no interest, can be volatile, costs money to store, and cannot be expanded quickly to meet changing global liquidity needs. These limitations ensure that major currencies and government bonds will continue playing critical roles in the global financial system.
Still, the message from central banks appears clear. They are not abandoning the dollar, but they are placing greater emphasis on owning assets that cannot be frozen, sanctioned, or created by governments.
For decades, U.S. Treasuries occupied the top spot in central bank reserve portfolios. Today, gold has taken that position. Whether this proves to be a temporary response to geopolitical uncertainty or the beginning of a lasting realignment in global finance may become one of the most important economic stories of the coming decade.
