The fifth part of this series focused on rising government debt as a structural driver of demand for gold. Today’s sixth part is devoted to a more technical aspect that is nonetheless crucial to price dynamics: the small size of the global gold market compared to the bond and stock markets.
Gold: A Flyweight Next to the Heavyweights—Bonds and Stocks
The global bond market is one of the largest capital markets in the world. According to calculations based, among other sources, on data from the Bank for International Settlements, the global bond market capitalization recently stood at around 133 to 137 trillion U.S. dollars. The global stock market is of a similar order of magnitude, at several dozen trillion U.S. dollars.
Compared to these two asset classes, the gold market is significantly smaller, regardless of whether it is measured by central bank reserves of approximately 36,600 metric tons of gold or by the total above-ground gold supply, estimated at just over 200,000 metric tons. According to market estimates, the value of all gold in existence above ground currently amounts to a low- to mid-double-digit trillion figure in U.S. dollars.
This discrepancy is also evident in daily trading volume: According to industry estimates, more than one trillion U.S. dollars is traded daily on the bond market, while global stock markets also see high three-digit billion figures. By contrast, daily trading in physical and paper-based gold is, according to most available estimates, many times lower.
Why a small market size creates a leverage effect
This difference in scale gives rise to a simple yet powerful mechanism: If investors, asset managers, and central banks shift just a small percentage of the capital they have previously held in bonds and stocks toward gold, this small percentage—when measured against the massive bond and stock markets—already amounts to a very large absolute sum relative to the size of the gold market.
A capital inflow that would be barely noticeable in the bond market itself can represent a significant surge in demand for the comparatively small gold market and cause the price to move disproportionately sharply. The effect is that of the proverbial elephant in a china shop, which begins to rotate slowly but surely around its own axis.
This mechanism partly explains why even a moderate shift in the strategic asset allocation of central banks and large institutional investors can lead to noticeable price swings in gold. Whether this occurs as part of the diversification away from the U.S. dollar described in the previous parts of this series or due to growing concerns about debt sustainability is ultimately irrelevant.
Each individual motive for the reallocation is capable of triggering massive price spikes. The significantly positive inflows into physically backed gold ETFs seen again in recent months fit into this picture. They give us a taste of what will happen when the broader investor base discovers gold for itself.
This comparison of scales also provides an important context for understanding the gold rally during the first trading days of August 2026: A weekly gain of seven to eight percent sounds dramatic in and of itself, but given the small size of the market, it can be explained by relatively modest capital movements.
Conversely, this also means that further shifts—which are small relative to the large capital markets for stocks and bonds—could be enough to sustain the upward trend in gold should the structural tailwinds described in previous sections—weaker economic data, declining confidence in the U.S. dollar, ongoing central bank purchases, and growing debt concerns—continue.
A Double-Edged Sword
It is important to note that this leverage effect works both ways: just as moderate inflows can drive the price disproportionately higher, comparatively small outflows—such as those resulting from short-term profit-taking following a sharp price rise in the gold market—can also lead to significant setbacks.
The small size of the market thus tends to make gold more volatile than the large, more liquid bond and stock markets, a factor every investor should take into account when determining the size of their position. These effects also apply to silver. What’s more: Since the silver market is significantly smaller than the gold market, not only do the effects described above also occur here, but silver is also the significantly more volatile precious metal compared to gold.
The seventh and final part of this series will focus on the supply side: We will explore why gold production can react only very slowly even when demand is rising sharply, and what this means structurally for the long-term price trend.
