The Mystery of 187 Tonnes: How a Central-Bank Data Revision Changed Gold’s Bull-Market Story

A World Gold Council revision cut estimated first-quarter 2026 central-bank gold buying from 244 tonnes to 57 tonnes, reclassifying 187 tonnes as OTC and other demand. The correction changes who appeared to support the rally, while leaving the broader gold-demand picture more complex.

The Mystery of 187 Tonnes: How a Central-Bank Data Revision Changed Gold’s Bull-Market Story


A 187-tonne revision has changed one of the most important stories behind gold’s recent bull market. On 30 July 2026, the World Gold Council published updated demand data showing that estimated central-bank purchases in the first quarter were only 57 tonnes, not the 244 tonnes originally reported on 29 April. The missing metal did not disappear from the market. It was reclassified into the over-the-counter and other-demand category after new market information and further analysis by Metals Focus.

The correction matters because central banks have been widely treated as a durable source of demand and a structural explanation for gold’s record-breaking advance. A reduction of 187 tonnes from one quarter does not erase that long-term trend, but it weakens the claim that official-sector buying remained exceptionally strong throughout early 2026. It also exposes how difficult it is to measure transactions involving institutions that do not disclose purchases promptly or route activity through less transparent channels.

What changed in the data

The chronology is unusually important. The World Gold Council’s first-quarter report, published on 29 April 2026, initially estimated net central-bank demand at 244 tonnes. In July, an erratum was added to that report stating that newly available market data and additional analysis had reduced the estimate to 57 tonnes. The 187-tonne difference was reassigned to OTC and other demand.

The revised figures appear in the second-quarter Gold Demand Trends report, published on 30 July. Its updated table records 56.5 tonnes of central-bank and other official-institution demand in the first quarter, rounded to 57 tonnes in the accompanying commentary. It also records 243.7 tonnes of OTC and other demand for the same period, reflecting the reclassification as well as smaller routine revisions elsewhere in the balance.

This distinction is essential. The revision does not mean global gold demand was overstated by 187 tonnes. It means analysts changed their assessment of who bought the gold and through which market channel. For the bullish narrative, the identity of the buyer matters because a reserve manager is often assumed to have a longer investment horizon and less price-sensitive behaviour than a hedge fund, family office, commodity trader or other OTC participant.

Why the original estimate was vulnerable

Central-bank gold statistics combine reported reserve changes with estimates of activity that has not yet appeared in public data. The World Gold Council notes that its reported figures draw on sources including the International Monetary Fund and individual central banks, while broader quarterly demand estimates rely on Metals Focus and other market intelligence. Reporting can be delayed, transactions can involve swaps or sovereign wealth funds, and some official institutions may disclose only part of their activity.

The revised report says unreported official-sector buying remained elevated in the second quarter. That creates an unavoidable measurement problem: analysts must distinguish bullion acquired by central banks or other state institutions from metal purchased in opaque OTC transactions by private participants. When new evidence changes that attribution, historical quarterly figures can move sharply even if the estimate for total physical demand changes much less.

The first quarter was also complicated by visible selling. According to the updated World Gold Council review, Turkey, Russia and Azerbaijan were important sources of pressure during the period. Country-specific liquidity management, reserve operations and swap activity can make a single quarter look very different from the longer-term strategic trend.

The central-bank story weakened, but did not vanish

The second quarter produced a sharp rebound. Estimated central-bank net buying reached 289 tonnes, more than five times the revised first-quarter level and the highest second-quarter total in the series cited by the World Gold Council. First-half demand therefore reached 345 tonnes, the weakest first half since 2022 but still a substantial amount of official-sector accumulation.

Reported activity was led by Poland, which added 51 tonnes in the second quarter, while China added 33 tonnes. Uzbekistan, Kazakhstan, Jordan and the Czech Republic were among the other reported buyers. Russia was the largest reported seller in the quarter, reducing holdings by 22 tonnes, while Turkey’s sales slowed materially.

Survey evidence also remains supportive of the strategic gold thesis. The World Gold Council’s 2026 reserve survey, conducted from 5 February to 19 May among 76 respondents, found that 89% expected global central-bank gold reserves to increase over the following 12 months. A record 45% expected their own institution’s holdings to rise. The most frequently cited motivations included diversification, crisis performance, inflation protection and geopolitical-risk management.

Those intentions should not be treated as guaranteed purchases. Survey responses are anonymous, expected allocations can be delayed, and reserve managers may change plans when prices, liquidity needs or exchange-rate pressures shift. The data revision is a reminder that stated strategic interest and measured quarterly buying are related but not identical.

How the revision changes the bull-market narrative

Before the correction, the first-quarter figure suggested that central banks had continued buying at roughly the strong pace seen in recent years despite record prices. The revised number presents a different sequence: official demand slowed dramatically in the first quarter, then recovered in the second. That makes the first-half market more dependent on private investment channels than the original data implied.

OTC activity is harder to interpret because the category can include several types of institutional transactions and does not reveal a single motivation. Some buyers may still have long horizons, but others may respond more quickly to momentum, leverage, interest rates or changes in risk appetite. As a result, reclassifying 187 tonnes from central banks to OTC and other demand potentially makes the underlying support for gold look less stable than previously assumed.

Other second-quarter figures reinforce that mixed picture. Total gold demand, including OTC, was unchanged from a year earlier at 1,269 tonnes, taking first-half demand to 2,522 tonnes, up 2%. Central banks bought 289 tonnes in the second quarter, but gold-backed exchange-traded funds recorded 45 tonnes of outflows. Bar and coin demand held near 307 tonnes, while jewellery consumption fell to 278 tonnes, its lowest quarterly level since the pandemic period.

The price backdrop was equally volatile. The World Gold Council reported that gold reached an intraday high above US$5,500 per ounce in January before falling below US$4,000 in late June. The average LBMA PM price in the second quarter was US$4,506.29 per ounce, 8% below the first-quarter average but 37% above the same quarter of 2025. This sequence suggests that strong strategic demand did not prevent a major correction when positioning, yields, currency conditions and risk sentiment changed.

What remains unknown

The biggest unresolved question is the identity and durability of the buyers behind the reclassified 187 tonnes. The public data do not establish whether the metal was acquired by a small group of large private institutions, dispersed across multiple OTC participants, or linked indirectly to official entities that had not yet reported. Future disclosures could still trigger further revisions.

It is also unclear whether the second-quarter rebound in central-bank buying represents a return to the unusually high annual pace seen from 2022 onward or only a temporary recovery after first-quarter selling. The World Gold Council expects another strong year, but below the 2025 total. That outlook depends on geopolitical risk, reserve-diversification policy, the level of gold prices and the liquidity needs of individual countries.

Risk context for traders

For forex and gold traders, the main lesson is not that the bull market has been disproved. It is that one of its most widely cited demand pillars is measured with greater uncertainty than headline figures may suggest. Central-bank purchases remain significant, but quarterly estimates can change, and private OTC demand may be more sensitive to financial conditions than official reserve accumulation.

Gold’s direction will therefore continue to reflect several forces at once: central-bank and private investment demand, real yields, the US dollar, geopolitical stress, ETF flows, jewellery affordability and recycling. A future revision, a change in reserve disclosures or a shift in interest-rate expectations could alter the market narrative again. The revised data should be read as a warning against relying on a single demand category as a complete explanation for price performance.
