The cube

17 October, 2024

The bulk of existing research places financial investment at the forefront of price determination for gold but while the short-term impact of financial markets is undeniable, the long-term importance of other sources of buying is even more so.

The estimated above-ground stock of gold, at 212,582 tonnes, which we depict as a cube, is a balance sheet snapshot of gold ownership (Figure 2). It is remarkable for a number of reasons.

The cube illustrates how the total stock of this ubiquitous metal could occupy a physical space barely larger than three Olympic-sized swimming pools. In addition, it reveals how little financial investment – (referring here to physically backed gold ETFs and over-the-counter (OTC) physical holdings) has been amassed by market participants over the years in relation to other sources of demand – a misleading statistic given the vast volumes of gold that flow through financial centres every day.

That so much of this hypothetical cube is not owned via financial instruments implies that any explanation of its total distribution must consider factors beyond those solely linked to the day-to-day decisions of financial market participants.

The distribution of the cube also suggests that the price of gold has been driven by two distinct components: an economic component combined with a financial component.

We illustrate an example of these dynamics in Chart 1 using quarterly data from 2000, adding COMEX futures net positions to the mix to capture derivatives activity.1 This compares the cumulative net consumer flows (jewellery plus technology minus recycling) to flows relating to gold financial instruments (gold ETFs, plus OTC net buying and net long futures positions). The volume from gold accumulated through financial instruments is more than twice as volatile as net consumption, yet accumulates at a much lower rate.

It is this accumulation – whether for individuals, the reserves of select central banks or even investment for long-term savings – that we attribute to an economic component. The financial component represents, more tactical considerations, such as hedging demand, whether from individual or institutional investors.2 

These components closely match the drivers we have outlined in our other pricing models, GRAM and Qaurum. Additional drivers, including risk and uncertainty and momentum are less relevant in the long run but feature heavily in the short run (see Focus 1).

Focus 1: Gold's key drivers

Gold’s performance responds to the interaction of its roles as a consumer good and as an investment asset. It draws not only from investment flows but also from fabrication and central bank demand.

In this context, we focus on four key drivers to understand its behaviour across periods:

Economic expansion: periods of growth are supportive of jewellery, technology and long-term savings

Risk and uncertainty: market downturns, inflation and geopolitical risk often boost investment demand for gold as a safe haven

Opportunity cost: the price of competing assets, including bonds and currencies, influences investor attitudes towards gold

Momentum: capital flows, positioning and price trends can boost or dampen gold’s performance.

Footnotes

  1. Although COMEX futures ownership, and indeed that on other futures exchanges, does not explicitly exist in the cube, eligible and registered stocks do, and some positions in the futures market are hedged using physical gold. More importantly, we add futures to the mix as they play an important role in price discovery in the short term and add to short-term turnover in markets.

  2. The dual nature of gold drivers was covered extensively by Goldman Sachs as part of its Fear and Wealth framework; see Appendix D for our analysis. In addition, the model developed by Barsky et al. (2021) employs real GDP as a significant driving factor behind the price.
