A gold bar doesn’t pay the rent

Gold is the only asset humanity has considered valuable for over 5,000 years. Empires have risen and fallen, currencies have been printed and destroyed, entire economies have collapsed—yet gold is still there, with its intrinsic weight and enduring appeal.

So it’s no surprise that in times of uncertainty, the same question always comes up: “Should I invest in gold?”

The short answer is: it depends on what you mean by “invest.”

Because gold is fundamentally different from everything else in a portfolio. It produces nothing. It pays no dividends. It generates no interest. It creates no profits. It doesn’t hire employees or build factories.

The only way to make money from it is to sell it to someone willing to pay more than you did. (Warren Buffett famously described it as an asset you “look at and hope someone else wants more than you do.”)

That said, it’s rarely wise to allocate too much gold within a financial portfolio—let alone across total wealth. But its role, if properly understood and sized, can make sense.

Let’s break down when, how much, and how to use it.

Gold as an emotional safe haven

Whenever markets fall, inflation rises, or geopolitics become unstable, gold comes back into the spotlight. Headlines fill with “new all-time highs,” gold coin dealers ramp up their marketing, and the “safe haven” narrative becomes irresistible.

The problem is that most people buy gold for emotional reasons, not strategic ones. They buy after prices have already risen (because “now is the time”), they buy too much (because “at least this is safe”), and they buy it in the wrong way (physical coins with high costs and wide spreads).

Most importantly, they confuse insurance with investment.

These are not the same thing. Home insurance is not a real estate investment. Gold in a portfolio is not an “investment in gold”—it’s a hedge against extreme scenarios. And like any insurance policy, it comes with a cost. If nothing catastrophic happens, that gold simply drags down overall returns.

Allocating 25–30% of your wealth to gold is not diversification. It’s a bet: that the world will turn out worse than markets currently expect. It’s a legitimate choice—but you need to be fully aware of it.

What history actually says (not just the last few years)

Gold’s real return: neither miracle nor disaster

Over very long periods, gold has preserved purchasing power. Nothing more. Its historical real return (after inflation) is about 1% per year over a century-long horizon. In practical terms, 100 grams of gold in 1925 had roughly the same purchasing power—adjusted for inflation—as 100 grams in 2025.

Does that sound low? It is. Compare it to global equities, which have delivered around 5–7% real annual returns over the same period. The power of compounding turns that gap into a massive difference over 30 years.

But averages hide the path—and this is where things get interesting.

Two opposite decades

Anyone looking only at 2000–2025 sees a spectacular run: gold rose from about $280 per ounce to over $2,000, outperforming equities in several phases.

But look at the previous two decades, 1980–2000, and you’ll see the opposite: gold lost roughly 70% in real terms. Twenty years of negative returns. Two decades in which investors treating gold as a “safe investment” destroyed wealth, while equities delivered one of the longest bull markets in history.

Here’s the full picture:

Period	Gold (real)	Global equities (real)
1980–2000	~ –70%	~ +400%
2000–2025	~ +500%	~ +200%
1925–2025	~1% annually	~5–7% annually

The key takeaway? Gold is not an asset you build a financial plan on. It’s an asset you add to a financial plan to make it more robust. That distinction matters.

Correlation: this is where gold earns its place

Gold’s real value isn’t in its return—it’s in its correlation, or more precisely, its lack of correlation with other asset classes.

When equities fall sharply, gold tends to rise or remain stable. Not always, not perfectly—but often enough to reduce overall portfolio volatility. In technical terms, gold acts as a diversifier.

There’s no magic here. It’s simple supply and demand: during periods of panic, investors sell risky assets and move into perceived safe havens. Gold has been at the top of that list for thousands of years.

That’s exactly why well-known portfolios include it:

Permanent Portfolio (Harry Browne): 25% stocks, 25% long-term bonds, 25% gold, 25% cash.
Historical maximum drawdown: about –13% (vs –51% for a 100% equity portfolio)
All Weather (Ray Dalio, simplified): 30% stocks, 40% long-term bonds, 15% medium-term bonds, 7.5% gold, 7.5% commodities

Different philosophies, same principle: gold is not there to generate returns. It’s there to provide protection when everything else struggles.

It’s insurance—not a growth engine.

How much, how, and at what cost

How much gold should you hold?

The pragmatic answer—supported by both academic research and sound asset allocation practice—is: between 5% and 10% of your invested portfolio. Not your total net worth, but the portion that is actually invested.

Below 5%, the diversification benefit is negligible. Above 10%, you’re making a directional bet on gold rather than diversifying. Harry Browne’s 25% allocation is a theoretical extreme—it works well in backtests but requires strong discipline and comes at the cost of significantly lower returns during normal market conditions.

For the vast majority of long-term investors, 5–10% is the reasonable range.

How to invest in gold: ETCs, physical gold, and mining stocks

Not all ways of gaining exposure to gold are equal. The differences—in cost and efficiency—are substantial.

The rational choice for most investors is a physically-backed ETC. It trades on the stock exchange like an ETF, has relatively low costs, and is backed by physical gold stored in secure vaults (typically in London).

Two of the most widely used and liquid options in Europe are:

Invesco Physical Gold (ISIN: IE00B579F325)
iShares Physical Gold (ISIN: IE00B4ND3602)

A key note: ETCs are not UCITS funds. Technically, they are collateralized debt securities. This means there is a theoretical issuer risk, mitigated by the fact that the physical gold is segregated and owned by investors.

It’s not a risk to ignore—but it’s also not a reason to start buying gold bars and hiding them under your mattress (unless you’re following your grandfather’s playbook, with all due respect to him).

Gold is insurance. Treat it that way.

Investing in gold doesn’t mean believing in a financial apocalypse. It means acknowledging that the future is uncertain—and since gold produces no cash flow, any price increase is not driven by earnings, valuations, or growth, but purely by supply and demand.

Gold in a portfolio works like home insurance: you hope you’ll never need it. If everything goes well—economic growth, rising markets, stable inflation—gold will drag on performance. That’s the cost of the policy.

But when things go wrong (and periodically, they do), gold is what prevents your portfolio from dropping 40–50%—and your brain from hitting the “sell everything” button at the worst possible moment. And since an investor’s brain is their worst enemy, this is a value that doesn’t show up in returns, but is worth a fortune in long-term results.

A 5–10% allocation to gold won’t make you rich. But it might stop you from making the wrong decision at the worst time. And in personal finance, avoiding mistakes matters far more than chasing returns.

FAQ

Is gold really a safe haven?
It depends on the time horizon. In the short term, during acute crises, gold has historically held its value or risen while equities were falling. But over intermediate periods (5–10 years), gold can experience significant losses—investors who bought at the 1980 peak had to wait 28 years to break even in real terms. It’s a hedge during panic, not a guarantee of consistent returns.

Is physical gold better than ETCs?
For 99% of investors, a physically-backed ETC is the most rational choice. It’s cheaper (0.12–0.25% annually vs. 3–8% spreads on coins), more liquid (can be sold in seconds, not days), and doesn’t require storage. Physical gold only makes sense for very large portfolios seeking a component completely outside the financial system—and willing to accept the higher costs and illiquidity.

If gold produces nothing, why not invest only in stocks and bonds?
Because the perfect portfolio on paper is not the perfect portfolio in reality. Equities can lose 50% in a matter of months, and when that happens, the average investor—who was “aggressive” in theory—panics and sells. Gold, by reducing overall volatility, increases the likelihood of sticking to the plan. And the best portfolio isn’t the one with the highest expected return—it’s the one you can hold over the long term.

Can I use gold as the main investment in my portfolio?
No. Gold produces no cash flow, doesn’t participate in global economic growth, and its long-term real return is about 1% annually—far below stocks and bonds. Allocating 30–50% of your wealth to gold is not diversification—it’s a bet on a single scenario (prolonged crisis, hyperinflation, systemic collapse). That scenario may happen, but building a financial plan around it is like insuring your house for ten times its value. The premium becomes the problem.
