Does gold still deserve a place in a diversified portfolio?

Given the recent bout of geopolitical uncertainty, gold – long regarded by many investors as a safe haven asset – has had a strong run. However, as tensions have started to ease (at least for the moment), some have begun to question whether the commodity can still play a role in a diversified portfolio. We believe the answer is yes.

Why we turned to gold in 2019

At Orbis, we built up the gold exposure in our multi-asset portfolios in 2019. This change was driven by increasing concerns about deficit and debt levels in the US and developed world. Governments were spending far too much money, which in our view put their currencies at risk.  The US alone is currently over $36 trillion in debt – the highest national debt in the world – and President Trump’s “big, beautiful bill” threatens to add another $3 trillion to that figure.[1]

The market’s reaction has been swift, with the US dollar suffering its worst first-half performance since 1973.[2] Rising debt erodes confidence that a government can repay without resorting to money printing or inflation, so investors demand more compensation or sell the currency, driving its value down.

Gold, however, can be considered a 9,000-year-old currency that’s never been devalued, never gone broke. From that perspective, it is the world’s most enduring store of value, especially when the US dollar (or any fiat currency) looks expensive relative to fundamentals.

Supply is predictable; demand is the wild card

From an investors point of view, there are two ways to look at gold. One is strictly as a commodity, so supply and demand. Recently, demand has been outstripping supply, so the price has been going up. We know roughly what the supply of gold is going to be each year, although that is declining over time because the metal is getting harder to find.

Demand, by contrast, is far less predictable. In recent years it has been propelled mainly by aggressive central-bank purchases and steady buying from China and India. However, demand from Western markets has been relatively subdued, as their focus has been more on AI and big tech, the areas where momentum has been strong over the last few years.

But, when that momentum rolls over and fades out, the retail investors of the world will likely try and shift into where there’s still momentum and that includes gold. Evidence is emerging to support this thesis: gold ETFs saw net inflows in the first half of this year after 18 straight months of outflows, driven largely by U.S. investors.[3] That renewed interest is spilling over from bullion to the often-overlooked gold-mining equities. Because central banks buy the metal, not the miners, the latter remain mispriced and overlooked, offering a fertile hunting ground.

Rotating from bullion into miners – without abandoning the hedge

As bullion climbed, gold-mining shares lagged, so we’ve gradually been trimming our direct gold exposure and shifting that capital into miners. This year, that lag has flipped and the miners have started outpacing the commodity for the first time in a long time. So every time gold hits a new level we’ve been top slicing the commodity weighting and recycling it into either gold miners, or other areas we find interesting such as inflation protected bonds.

That said, it doesn’t mean we think that gold's rolling over and going down. We're just being conscious of risk – the higher something goes, the more risk there is that it will fall sharply.

In theory gold can continue to go higher, especially if major currencies such as the US dollar devalue. If macro, geopolitical or regional events cause fiat currencies or paper currencies to fall, then gold could rise as a so-called “safe haven”. In our view, we think some currencies will go down relative to gold, because governments are still spending too much money – deficits are too high and debt levels are going up and up and up. That makes paper currencies worth less against all material items, of which gold is the best representation.

With that in mind, gold should in our view go up over time, and we think it still has a decent place in a diversified portfolio. And while we have been trimming it in favour of inflation protected bonds, we still hold a significant position in the Orbis multi-asset portfolios.

In commenting on this item, let me warn the reader that I have been called a gold bug on this newsletter before and therefore please treat everything I write with a pinch of salt, as it definitely goes against the current orthodoxy. In my view and definitely in the view of J. Pierpont Morgan, considered the greatest banker ever, "gold is money, nothing else". From the individual's point of view, the fact that gold seems immune to inflation, is a good thing. From a government's point of view, this is a bad thing, as inflation works as a tax that does not require legislation. When Roosevelt banned gold money in 1933, he wanted to have inflation. As Thomas Sowell has stated "the problems of today are the solutions of yesterday". We need money and we need income producing investments. Fiduciary money is no store of value and saving in it is a road to disappointment and rip off. This is why the young struggle to save a housing deposit. It is like trying to run up the down escalator. On the other hand Warren Buffet certainly speaks wisdom when he says if you save an ounce of gold and keep it for 20 years, at the end you still only have an ounce of gold. Good productive investments can, in that time produce more value measured in gold than that. The biblical "Parable of the Talents" may have a spiritual message, but it has a very practical message too. As for real estate, here is my early experience. I purchased my modest family home in a nice inner city suburb of Sydney, in 1970. This was a difficult year to get a bank loan, because the world money was still in the Bretton Woods system. However I managed, with the help of my employer. In 1971 we had the Nixon shock by which the world abruptly left the gold backed money and launched into the "brave new world" of well..nothing much. By the time Gerald Ford made owing gold legal again the value of my home was worth 350 troy oz of gold. Today after 50 years or more, the same house is worth, 350 troy oz of gold. No capital gain at all.

That seems to focus on short-term matters. As a long-term investor I prefer the Buffett reasoning on gold. I note you reason it is both a commodity and a currency. As a commodity demand is hard to predict. As a currency I agree that if a country runs bad deficits then its currency will go down against trading partners

9,000 years is short-term relative to the age of the universe, but relatively long-term from an investing perspective :-)

Your article while learned bases its thesis on gold’s scarcity and history as a resilient store of value. However, there’s a paradigm shift underway that demands mention: commercial-scale synthetic gold production via nuclear transmutation is now an engineering—not scientific—problem. Bombarding mercury-198 with neutrons in fusion or advanced fission reactors produces gold-197—a process already demonstrated at research scale, with companies like Marathon Fusion commercialising gigawatt-scale reactors projected to yield tonnes of gold annually in the 2030s (see: dailysabah.com/life/science/nuclear-fusion-startup-says-making-gold-from-mercury-possible and indiatoday.in/technology/news/story/silicon-valley-startup-says-it-has-found-way-to-turn-mercury-into-gold-if-proven-may-hit-gold-prices-2761706-2025-07-26).

Recent research and preprints, as well as accelerator and reactor tests, confirm the transmutation chain is real—and scaling is now about capital and engineering, not physics. Safety handling and regulation are hurdles, but the supply ceiling is permanently altered. The analogy is synthetic diamonds—the perception changed before the supply curve did, collapsing the price premium.

If gold’s value rests 90% on belief in irreversible scarcity, that belief is on borrowed time. Trust and narrative can shift swiftly once credible supply threatens to flood the market, which may happen years ahead of actual production ramp-up. My take is that investors should be aware: the scarcity premium is being eroded, and markets will likely begin to price this risk long before the first commercial tonne leaves a fusion plant. This is a technological disruptor the asset allocation debate cannot afford to ignore.’

'one gigawatt could generate around 5,000 kilograms of gold every year using this approach'

1 GigaWatt = 26 * 365 * 1000 MWh / y
Value electricity:
= $30 * 24 * 365 * 1000 / y
= $262,800,000 / y

Value gold:
= $170,000 / kg * 5,000 kg / y
= $850,000,000 / y

3,600,000 kg gold mined per year.
