Gold’s Reserve Boom Is Less About Buying Than the Price Doing the Work

Gold’s rebound above $4,000 is arriving with an awkward message for one of the market’s strongest narratives: central banks may still be committed to bullion, but the apparent surge in gold’s reserve status has been amplified as much by valuation as by fresh purchases.

Samarium’s gold-price series rose from $3,994.95 to $4,017.48 in the latest 24-hour window, a gain of $22.53, or 0.56%. The metal traded between $3,967.15 and $4,017.90, recovering from an intraday dip and finishing close to the session high. That resilience followed a difficult week in which spot gold lost about 2.6% as oil-driven inflation fears and expectations of tighter US monetary policy outweighed the traditional haven bid.[1]

The deeper issue is how investors interpret official-sector demand. A new IMF note argues that gold’s renewed prominence in central-bank reserves largely reflects valuation gains from the higher gold price rather than a wholesale reallocation of reserve portfolios.2 The European Central Bank reached a similar conclusion in its June review of the international role of the euro: gold accounted for about 27% of total official reserves at the end of 2025, ahead of the euro and US Treasuries, but much of that ranking disappeared when the metal was valued at its end-2023 price.3

That does not make the central-bank story false. It makes it more precise.

The reserve share rose faster than the tonnage

Gold’s reserve share can increase in two ways. A central bank can buy more metal, or the price of its existing holdings can rise. The last two years delivered both, but the second effect has been unusually powerful.

The ECB estimated that gold prices rose by about 60% in 2025 after gaining roughly 30% in 2024. At current market values, gold represented 27% of official reserves at the end of 2025. Repriced at end-2023 levels, its share fell to about 16%, roughly equal to the euro and still well below the 26% share of US Treasuries.3

The IMF’s latest COFER release points in the same direction. The dollar’s share of disclosed foreign-exchange reserves increased to 57.13% in the first quarter of 2026 from 56.42% in the previous quarter, while the IMF said gold’s rise relative to Treasuries was driven almost entirely by valuation effects and was not mirrored by a collapse in the dollar’s reserve share.4

This distinction matters because a price-driven increase in reserve weight does not create the same persistent physical demand as a policy decision to shift reserves from bonds or currencies into bullion. It also means that a correction in gold can mechanically reduce its reserve share even if central banks sell nothing.

Buying remains real, but it is concentrated

The official sector is still adding metal. World Gold Council data show central banks bought a net 41 tonnes in May, led by Poland with 18 tonnes and China with 10 tonnes. Uzbekistan, Kazakhstan and Singapore also added gold, while Turkey and Russia were net sellers.5

The buying is meaningful, but it is not universal. A relatively small group of recurring purchasers has accounted for much of the reported demand. Poland had accumulated 64 tonnes year to date by May, while Uzbekistan and China had added 33 tonnes and 25 tonnes respectively.5

That concentration sits beside extremely bullish survey sentiment. In the World Gold Council’s 2026 central-bank survey, 89% of respondents expected global official gold reserves to rise over the next 12 months and a record 45% expected their own institution to increase holdings.6 Central banks reported that crisis performance, diversification, inflation protection and geopolitical risk remain central reasons for holding bullion.7

The survey captures intent; the IMF and ECB analysis captures the balance-sheet arithmetic. Both can be true. Reserve managers may want more gold even while the headline increase in gold’s share is being exaggerated by price.

High prices create their own brake

Gold near $4,000 is strategically attractive but operationally expensive. The IMF note highlights the asset’s drawbacks for reserve managers: it produces no yield, can be volatile, requires storage and insurance, and is less immediately useful than major currencies for intervention or emergency liquidity.2

The ECB also noted that soaring prices may have restrained additional official purchases. In the Eurosystem, the volume of gold reserves was almost unchanged between April and May at about 347.5 million fine ounces, while their market value fell from €1.375 trillion to €1.352 trillion as prices moved.89 That is a clean example of how reserve values can swing without meaningful changes in physical holdings.

Funding is another constraint. Half of respondents in the World Gold Council survey said future gold purchases could be financed through domestic buying programmes in local currency, while 38% pointed to selling existing reserve assets.6 The second route is not a free allocation decision: replacing interest-bearing securities with non-yielding bullion becomes harder when policy rates remain high.

The Federal Reserve’s July monetary-policy report said inflation remained above the 2% objective and that the federal-funds target had stayed at 3.5% to 3.75% since the start of the year.10 Governor Lisa Cook said this week that inflation risks still concerned her more than employment risks, even after softer consumer and producer-price data.11 For reserve managers, that keeps the opportunity cost of gold visible.

Private flows may matter more at the margin

The latest price rebound may owe more to investors than to official buyers. Global precious-metals funds attracted $376 million in the week through July 15, reversing eight consecutive weeks of outflows.12 Gold-backed ETFs still recorded $8.9 billion of outflows in June, but first-half flows remained positive at $8 billion and Asian funds delivered their strongest first half on record.13

Positioning has also remained firmer than the price action suggests. World Gold Council analysis showed COMEX net longs rose 16% in June to 538 tonnes even as gold weakened, with larger traders holding more stable exposure than smaller non-reportable participants.13 The latest CFTC report provides the underlying futures-positioning framework for that market.14

That creates a more nuanced support structure. Central banks provide a long-term strategic floor, but ETF flows, futures positioning and macro expectations are likely to determine whether gold can hold above $4,000 in the near term.

The next test is whether official buying accelerates in tonnage, not merely in dollar value. If reported purchases broaden beyond the familiar buyers while ETF flows turn positive and rates peak, the reserve-diversification thesis will gain stronger physical evidence. If the price rises but tonnage stagnates, gold’s growing reserve share will remain partly an optical effect produced by the market itself.
