Higher gold values don’t prove governments sold dollars to buy gold

Japan’s gold became more valuable without an increase in its reported quantity. China reported increases in both quantity and value. That comparison exposes a missing link in a tempting interpretation of higher gold values alongside lower holdings of U.S. government debt: governments must have sold dollar assets to buy gold. The disclosures establish changes in reported holdings, but do not connect them into a government trade.4381

At end-July 2026, Japan reported a gold quantity of 27.20 million fine troy ounces, worth approximately $109.5 billion. At end-August, the quantity remained 27.20 million, while the value reached approximately $124.1 billion. The Ministry of Finance reports gold at market value, meaning what the holding is worth at the observation date.43

The relationship is quantity multiplied by the applicable valuation price. With reported quantity unchanged, a higher valuation price accounts for the higher total without requiring additional gold. This is an accounting explanation; it does not identify what drove the price. Nor do rounded quantities at two month-ends exclude trades between those dates.43

China’s State Administration of Foreign Exchange supplies a different quantity comparison: 76.08 million ounces at end-July and 76.73 million at end-August 2026. Their reported dollar values rose from approximately $306.4 billion to $350.1 billion. Here, the quantity increase establishes something the dollar totals alone cannot: China reported holding more gold. But the table does not identify the underlying transactions, their funding or its precise gold-price benchmark. The increase in total value cannot be treated as the amount spent acquiring gold.8

These official reserves are public assets. Japan’s report covers monetary authorities and other central government, excluding social security. It does not measure private Japanese wealth or just the Bank of Japan’s balance sheet. Japan also converts non-dollar assets at current exchange rates, so their reported dollar value can change without an exchange of the underlying asset.4

Treasuries add an ownership problem to the valuation problem. These securities are U.S. government debt. A 2025 Federal Reserve research note explains that most official dollar reserves are invested in Treasuries, which also attract private foreign investors. A country total includes those different kinds of holders. Treating it as a government’s trading account silently substitutes one decision maker for a much broader population of investors.101

From end-May to end-June 2026, Japan-attributed Treasury holdings fell from $1,143.1 billion to $1,116.7 billion, down $26.4 billion. Mainland China-attributed holdings fell from $659.3 billion to $633.4 billion, down $25.9 billion. These are changes in balances recorded at two dates, and they precede the July–August gold comparison. Placing the figures beside each other does not make them simultaneous movements or identify a common transaction.1438

Transactions, valuation and geographic attribution can all change Treasury balances. Long-term securities use market values, so their prices can move the recorded total. Bills and certificates use face value instead of market value, so that price explanation does not apply uniformly to the table. Treasury’s current reporting framework collects holdings, purchases and sales, and valuation changes separately. Subtracting successive balances does not isolate those components.2

Custody, or safekeeping through an intermediary, complicates the country label. Treasury illustrates this with a German investor placing a U.S. security with a Swiss bank: the holding is attributed to Switzerland. Changes in where securities are held, and trades between foreign holders, can affect country balances. To identify government sales, transaction records must distinguish government from private sellers and account for valuation and other changes in holdings. Establishing that those sales financed gold requires another link: evidence tracing the proceeds to gold acquisitions.28

Japan’s intervention disclosures show what direct evidence of government action looks like. Foreign-exchange intervention means authorities buying and selling currencies to influence exchange rates. Japan’s Finance Minister has the authority; the Bank of Japan executes operations on the minister’s behalf and instructions. The central bank’s execution role does not make it the independent author of the government’s decision.765

The Finance Ministry’s Foreign Exchange Fund Special Account supplies intervention funds. In the documented mechanism for supporting a weakening yen, dollar funds held in that account are sold to buy yen. This explains a concrete use for official foreign-currency assets and identifies what the dollars purchase. It does not, by itself, identify any securities sold to obtain those dollars.7

The ministry’s April–June 2026 release reports approximately ¥11.7 trillion of intervention, identifying dollar sales to buy yen on April 30, May 4 and May 6. Both direction and dates are explicit. All listed operations, however, occurred before the Treasury comparison’s end-May starting point. They cannot establish the cause of the subsequent holdings decline. The release identifies neither Treasury liquidation nor gold financing.61

For July 30–August 26, 2026, the ministry reports approximately ¥15.4 trillion of aggregate intervention. This release supplies neither individual operation dates nor which currencies were bought and sold; the earlier dollar-selling direction cannot simply be assigned to it. Its interval also differs from the month-end gold comparison. A yen-denominated total of operations cannot be subtracted from dollar-valued reserve balances to explain their movement.56438

These limits leave open whether authorities wanted to hold more gold and rely less on dollar assets. Historical evidence also shows that adding gold can coexist with Treasury buying. In a September 2026 Federal Reserve research note, Colin Weiss reports net official gold accumulation since 2008 alongside nearly $200 billion of net foreign official Treasury purchases from 2022 through April 2026. His analysis draws partly on Treasury and International Monetary Fund data. It supplies historical context without independently confirming the newer country observations. This broader coexistence does not establish how Japan or China financed any particular acquisition, or why.9
