Gold as a Financial Network: The Financialization of Gold through ETFs, Mining Equities and Tokenized Assets
This paper utilizes a time-varying parameter vector autoregressive framework to demonstrate that gold has evolved from a physical commodity into a tightly interconnected financial network, where price discovery and shock transmission have shifted toward exchange-traded and tokenized assets, with GLD acting as the primary net transmitter and physical gold as a net receiver.

For centuries, gold has been viewed as a solid anchor in a shifting economic world, a physical store of value that people could hold in their hands. It was a commodity, its worth tied to the metal itself, mined from the earth and traded in vaults. But over the last few decades, the way people interact with gold has changed fundamentally. It has moved from being just a physical object to becoming a complex financial instrument, traded through digital funds, mining company stocks, and even blockchain tokens. This shift, known as financialization, means that the price of gold is now driven less by the simple supply and demand of the metal and more by the behavior of investors, the flow of capital, and the mechanics of global markets. Understanding how these different forms of gold interact is crucial because it reveals whether gold still acts as a safe haven or if it has become part of a tightly woven web where a shock in one area instantly ripples through the entire system.
A team of researchers set out to map this new landscape, treating the various ways to own gold not as separate markets but as a single, interconnected network. They gathered daily price data for seven distinct types of gold assets: physical bullion, the largest gold exchange-traded fund, several funds that track gold mining companies, and two newer digital tokens that represent physical gold on a blockchain. By analyzing how price changes in one asset influenced the others over time, they built a picture of how information and financial shocks travel through the gold ecosystem. Their goal was to see who leads the market and who follows, and to determine if the rise of digital and financial products has changed the very nature of gold's value.
The study found that the gold market is now incredibly unified. The researchers calculated that more than 81 percent of the movement in any single gold asset is caused by shocks coming from the other assets in the system, rather than by news specific to that asset alone. This high level of connection means that the gold market behaves less like a collection of independent buyers and sellers and more like a single organism where a tremor in one part is felt everywhere. The data showed that the traditional physical market, where people buy and sell actual bars of gold, has lost its role as the primary driver of price discovery. Instead, the leadership has shifted to the financial and digital sectors.
Specifically, the largest gold exchange-traded fund emerged as the most powerful source of new information, acting as the main transmitter of shocks to the rest of the network. When this fund reacts to global economic news, that reaction quickly spreads to mining stocks and digital tokens. Gold mining stocks also play a significant role in sending signals to the market, often reflecting investor sentiment and broader stock market conditions alongside the price of the metal itself. Interestingly, the two digital tokens did not behave exactly the same way; one acted as a transmitter of information, while the other acted primarily as a receiver, absorbing the signals from the larger market. This suggests that even within the new world of digital gold, different products have different roles and levels of influence.
Perhaps the most telling finding was the changing role of physical gold. In the past, the price of the metal was set by the physical market, and financial products simply followed. The study shows this relationship has reversed. Physical gold now acts largely as a receiver, absorbing the price signals generated by the financial and digital markets. It has become the passive element in the equation, reacting to the decisions made in the more liquid, fast-moving trading venues. The researchers also observed that this connectedness is not a temporary phenomenon but a structural feature of the modern gold market, remaining high even during periods of extreme market stress or calm.
These findings have important implications for anyone investing in gold. The high degree of connection means that holding a mix of physical gold, mining stocks, and digital tokens may not provide the diversification benefits investors often seek, because a shock to the system will likely affect all of them at once. For regulators, the study highlights that the financial and physical sides of the gold market are now so intertwined that a problem in one area, such as a liquidity crunch in a major fund, could quickly destabilize the entire ecosystem. The research confirms that gold has completed its transformation from a simple commodity into a highly networked financial asset, where the flow of information and capital matters more than the movement of the metal itself.
