Gold Overtakes US Treasuries in Global Central Bank Reserves

A World Gold Council survey of nearly 60 central banks, cited by the ECB, identified the key drivers of official gold demand: diversification away from traditional reserve currencies, hedging against geopolitical risk, and the desire for a long-term store of value during times of crisis . The ECB's own October 2025 monetary policy account noted that the gold rally was "initially driven by central banks diversifying their reserves, especially in emerging markets," before being reinforced by institutional and retail investors .

The Role of Valuation Effects

Valuation effects from gold's surging price have been a major amplifier of its rising share in reserves. The ECB's October 2025 meeting account observed that the gold rally had "refuted historical correlations" as prices surged despite a strong US dollar and high real yields . This means that even if central banks had not purchased a single additional ounce, the market value and thus the share of their existing gold stockpiles would have risen significantly.

Germany's Bundesbank, for example, reported its gold position climbed to a historical high of €395 billion, a valuation-driven increase of €125 billion in a single year . Globally, a rising gold share in reserves is a reflection of both active buying and the passive revaluation of existing stocks .

Diversification, Not Just De-Dollarization

The shift towards gold is part of a broader reserve diversification trend, but it is crucial not to overstate this as a simple flight from the US dollar. A Federal Reserve paper published in June 2026 concluded that most countries' gold purchases reflect "modest diversification of international reserves" rather than a strategy of outright de-dollarization . Dollar-denominated assets still represent the largest overall share of global reserves at 42%, even if US Treasuries specifically have been surpassed by gold .

Diversification is happening on multiple fronts. The ECB's June 2025 report noted that non-traditional reserve currencies like the Australian and Canadian dollars saw their combined share rise to 9.6%, up 2.4 percentage points from pre-Ukraine invasion levels. Additionally, survey data indicated that two-thirds of reserve managers expected to further increase their gold allocations .

A separate, dramatic data point involving an $82 billion drop in US Treasury holdings at the New York Fed by March 2026 underscores the volatile environment. This sell-off was largely attributed to oil-importing nations like Turkey, India, and Thailand liquidating dollar reserves to support their currencies and pay for energy imports following the Iran war and the closure of the Strait of Hormuz . While not a direct cause of gold's rise, it illustrates the acute liquidity pressures that are making non-dollar reserve assets more attractive.

The Largest Official Sector Gold Buyers in 2025

Central bank net gold purchases totaled around 850 tonnes in 2025, a decrease from the record 1,045 tonnes in 2024 but still far above historical norms . A significant portion of this demand came from emerging markets.

Leading purchasers based on available data from the World Gold Council and other sources include:

• Poland: The National Bank of Poland was the largest buyer for the second consecutive year, adding approximately 102 tonnes to reach 550 tonnes in reserves. It reaffirmed its commitment to gold by raising its target allocation to 30% of total reserves .
• Kazakhstan: The National Bank of Kazakhstan was the second-largest buyer, adding around 57 tonnes in a record year driven by purchases from domestic production .
• Brazil: The Central Bank of Brazil re-entered the market after a four-year hiatus, purchasing 43 tonnes within a few months, bringing its total to 172 tonnes .
• China: The People's Bank of China continued its buying streak, adding 27 tonnes over 17 consecutive months, bringing its officially reported holdings to 2,306 tonnes .
• Turkey: The Central Bank of Turkey remained a steady accumulator, adding another 22 tonnes to its sizable holdings .

The Structural Limits of Gold as a Reserve Asset

Despite gold's ascent, the ECB and other analysts caution that it is not a wholesale replacement for fiat-based reserve systems. A World Gold Council survey of central bankers cited key motivations for holding gold—diversification and geopolitical hedging—implicitly highlighting its distinct role from interest-bearing government bonds .

Key structural limitations of gold compared to major fiat reserve assets include:

• No Yield: Gold does not provide coupon income, making it less attractive as an income-generating asset in a high-interest-rate environment .
• Physical Storage: As a physical asset, gold incurs custody, vaulting, and insurance costs that do not apply to electronic securities .
• Liquidity for Intervention: Gold is an excellent store of value but is less immediately usable than liquid foreign-currency deposits or securities for day-to-day foreign exchange intervention and settlement .
• Price Volatility: The ECB noted that gold's sharp rally had "refuted historical correlations," highlighting its potential for unpredictable price swings relative to other asset classes .
• Scalability: Gold's function is best understood as a complement to fiat reserve assets, not a scalable substitute for the depth and operational flexibility of major government bond markets .

The rise of gold to the top of the reserve-asset leaderboard is a landmark moment that signals deep unease with the geopolitical status quo. Yet its limitations ensure that the foundational role of major fiat currencies and their government bond markets in the global financial system remains intact.
