Why gold is a different kind of asset from everything else in your portfolio
Gold doesn't generate cash flow: it doesn't pay dividends like a stock, nor coupons like a bond. Its return depends entirely on its price rising, which makes it a bet on the supply and demand of the metal itself (as a store of value, as jewelry, as an industrial input) and on general confidence in the monetary and financial system, not on the growth of an underlying business.
This absence of cash flow is precisely the historical reason for its safe-haven reputation: during episodes of distrust in currencies or the financial system, like the ones we cover in our chapter on the gold standard and Bretton Woods, demand for gold as an alternative to traditional financial assets tends to spike.
What the historical evidence shows, without idealizing it
after peaking around 1980 (driven by that decade's high inflation), gold's price, adjusted for inflation, didn't sustainably surpass that real level again until well into the 21st century, nearly 28 years later. Anyone who bought gold as 'protection' in 1980 spent almost three decades without seeing their real purchasing power grow in that asset, while diversified equities, drawdowns included, generated a far higher real return over that same period.
This doesn't invalidate gold's role in specific moments: during the 2008 financial crisis and during episodes of severe hyperinflation, gold has protected purchasing power better than cash or assets denominated in the currency in crisis. The nuanced conclusion is that gold protects during specific episodes of stress, not that it guarantees continuous positive returns the way equities' structural long-term risk premium does.
How much gold makes sense in a diversified portfolio
The common practice among institutional managers who do include gold is to allocate between 5% and 10% of the total portfolio, treating it as a diversifier that behaves differently from stocks and bonds during periods of stress, not as the core of the investment strategy. Going significantly above that share starts to sacrifice the long-term expected return that equities do offer, without gold making up for that trade-off with cash flow of its own.
Accessing gold today doesn't require buying physical bars: there are ETFs backed by physical gold that track its price at low cost, as accessible as any other ETF, avoiding the custody, insurance, and liquidity issues of buying physical gold directly.
- Common allocation in institutional portfolios: between 5% and 10% of the total, as a diversifier.
- Gold generates no cash flow of its own: its return depends entirely on how its price evolves.
- Physical-gold ETFs: the most accessible and liquid way to invest, without the custody issues of physical gold.
Industrial commodities: a different bet, not a safe haven
Oil, copper, natural gas, or agricultural commodities behave very differently from gold: their price depends directly on the economic cycle (industrial demand rises in expansions and falls in recessions) and on supply dynamics very specific to each commodity (production decisions, weather, the geopolitics of producing countries), not on a search for safety amid uncertainty.
Investing in industrial commodities is, in practice, a cyclical bet on global economic activity, with considerable volatility and without the structural long-term risk premium that justifies holding equities for decades. They shouldn't be confused with gold or treated as a substitute for the diversification already offered by a well-built portfolio of equity and bond ETFs.
How to fit gold and commodities into your strategy, if you decide to
For the vast majority of individual investors with a long horizon, the core of the portfolio should remain diversified equities and, depending on your risk profile, bonds, following the same diversified framework we develop in our guide to index versus active investing. Gold can be added as a minor diversifier, with realistic expectations about its role (protection during specific episodes of stress, not a return driver), and industrial commodities only make sense for those who understand and consciously accept their cyclical, volatile nature.

Frequently Asked Questions
Not continuously. It has protected well in specific episodes of crisis or severe hyperinflation, but it has also gone through multi-decade periods with real returns essentially flat, as happened between 1980 and the early 2000s.
The common practice among institutional managers who include it is between 5% and 10% of the total, as a minor diversifier, not as the core of the investment strategy.
Because it generates no cash flow of its own: no dividends, no coupons. Its return depends entirely on its price rising, unlike a stock (business profits) or a bond (an agreed coupon).
No. Gold acts as a safe haven during crisis episodes; industrial commodities (oil, copper, agricultural goods) are a cyclical bet on economic growth and the physical supply and demand of each specific commodity, a completely different investment logic.
Through ETFs backed by physical gold, which track its price at low cost and with the same ease of buying and selling as any other ETF, avoiding the custody, insurance, and liquidity issues of physical gold.
