Central Bank Gold Buying: Will the Surge Persist Amid High Prices? Supply-Demand Dynamics and Derivatives Market Analysis

Recently, international gold prices have been oscillating near historical highs, with market sentiment swinging between expectations of Fed rate cuts and geopolitical uncertainties. Meanwhile, the sustained momentum of global central banks increasing their gold reserves over the past several years has become a core force supporting the upward shift in gold's price center. However, as gold prices remain elevated, the sustainability of central bank purchases is sparking widespread discussion among derivatives market participants.

Central Bank Gold Buying: From 'Supporting Role' to 'Leading Role'

According to reports from the World Gold Council, from 2022 to 2024, global central banks' annual net gold purchases exceeded 1,000 tonnes for three consecutive years, a scale equivalent to about a quarter of global gold production. Among them, central banks from emerging markets such as China, Poland, Singapore, and India were the main buyers. The People's Bank of China had increased its gold reserves for 18 consecutive months, and although it paused in May 2024, it later resumed purchases, indicating a long-term preference for gold reserves.

The backdrop to this wave of gold buying includes frequent geopolitical conflicts, challenges to the credibility of the dollar-based system, and a rising demand for diversification of global reserve assets. After Russia's foreign exchange reserves were frozen, many emerging market central banks realized that over-reliance on dollar assets carries risks, and gold, as a hard currency free of sovereign credit risk, has had its strategic value reassessed.

Supply-Demand Structure: Central Bank Demand Reshapes Market Balance

From a supply-demand perspective, global gold production is relatively stable, with mine output hovering around 3,500 tonnes annually, while recycled gold supply is more sensitive to price fluctuations. On the demand side, besides traditional jewelry consumption and industrial use, central bank purchases and gold ETF investments have become key variables in marginal pricing.

When central banks buy gold at a pace exceeding 1,000 tonnes per year, this demand almost 'locks in' nearly 30% of mine supply, significantly reducing the market's sensitivity to price fluctuations. In the derivatives market, open interest in COMEX gold futures remains at elevated levels, and implied volatility in the options market stays above historical medians, reflecting institutional investors' expectations of high-level volatility in gold prices.

Notably, central bank gold purchases are often not conducted through the futures market but directly in the spot market or over-the-counter transactions, which reduces price impact but also creates a certain disconnect between the price discovery function of the derivatives market and physical supply-demand dynamics. This structural change has led to increased volatility in gold futures basis and calendar spreads, offering opportunities for arbitrage strategies.

Central Bank Behavior Logic Amid High-Level Volatility

After gold prices repeatedly set new records in 2024, they entered a high-level consolidation pattern in 2025. Some market views suggest that central banks may slow down their purchase pace at high price levels, as rising costs reduce the cost-effectiveness of increasing holdings. However, historical experience shows that central bank gold buying decisions are more based on long-term strategic considerations rather than short-term price movements.

For example, during the 2011-2015 gold price downtrend, global central banks still maintained net purchases, albeit at reduced scales. Currently, the gold reserves of emerging market central banks as a proportion of their total reserves remain far below those of developed countries, implying theoretically significant room for increases. According to IMF data, gold reserves in developed countries like the United States and Germany typically account for over 60% of total reserves, while in countries like China and India, the proportion is only in single digits. This structural difference provides potential momentum for future gold purchases.

Furthermore, a 2024 survey of global central banks showed that over 80% of respondents expect global official gold reserves to continue growing over the next 12 months, a record high. This indicates that despite high gold prices, central banks' preference for gold has not waned.

Derivatives Perspective: Hedging and Risk Management

For the derivatives market, the persistence of central bank gold buying directly affects the term structure of gold futures and options pricing. If central bank purchases continue, spot market supply tightens, and forward discounts may deepen, impacting hedging costs. On the other hand, if central bank purchases slow down, gold prices may face downward pressure, and rising volatility would push up option premiums.

Some investment banks have noted in recent reports that central bank buying provides a 'floor support' for gold prices, but it is not a guarantee of unlimited upside. Against the backdrop of uncertain Fed monetary policy shifts and high real interest rates, the opportunity cost of holding gold rises, limiting the upside potential for gold prices. Therefore, derivatives traders tend to favor strategies such as bull put spreads or selling out-of-the-money call options to generate returns in high-level volatility.

Overall, the continuation of the central bank gold buying wave depends on multiple factors: whether global geopolitical risks escalate, whether the dollar-based system further weakens, and the urgency of reserve diversification among emerging market central banks. In the short term, high-level volatility in gold prices is unlikely to change, but in the medium to long term, central bank gold purchases provide solid structural demand for the gold market, which could become a significant long-term variable in derivatives pricing.
