How Much of a Portfolio Should Be Metals?

There is no shortage of confident answers to the allocation question. Traditional wealth managers tend to say five to ten per cent. Permanent portfolio advocates say twenty-five. Hard money enthusiasts online will tell you the correct number is considerably higher. All of these people are answering a different question without saying so, which is why the advice appears to conflict.

The useful starting point is not a percentage. It is a purpose. Once you know what job the metal is doing in your portfolio, the sizing follows naturally.

Three different jobs metal can do

• Insurance. A small allocation held permanently, intended to hold value when equities and bonds fall together. This job is usually satisfied by five to ten per cent.
• Diversifier. A structural allocation held because gold has historically had low correlation with stocks and bonds, improving risk-adjusted returns over long periods. Typically ten to twenty-five per cent.
• Savings vehicle. Metal held instead of cash, because the holder distrusts the long-term purchasing power of currency. This job has no natural ceiling and is a personal conviction rather than a portfolio theory position.

What the historical record actually supports

Gold has produced long-run returns roughly in line with inflation, with far higher volatility than cash and lower returns than equities over most multi-decade windows. Its value in a portfolio has rarely come from its own return. It has come from behaving differently to everything else, particularly during currency crises, sharp real-rate declines and periods of acute geopolitical stress.

That is the honest case for a modest permanent allocation: not that gold will outperform, but that it tends to be up when the rest of your portfolio is having its worst year. The cost of that insurance is the return you give up during the long stretches when it does nothing.

Silver behaves differently again. Roughly half of silver demand is industrial, which ties it to the manufacturing cycle and makes it considerably more volatile than gold in both directions. Platinum and palladium are more industrial still, dominated by autocatalyst demand. Treating all four as one asset class is the most common analytical mistake stackers make.

A practical way to size your position

Rather than picking a number and reverse-engineering a justification, work forwards from three questions.

• What would have to happen for me to sell this? If you have no answer, you are holding it as savings, not as an investment.
• How large a drawdown can I hold through without selling? Gold has had multi-year declines exceeding forty per cent. Size the position so that outcome is annoying rather than ruinous.
• Does this allocation stop me funding things with a hard deadline — a house deposit, school fees, retirement contributions with an employer match? Illiquid conviction should not outrank funded obligations.

Rebalancing, and why most people never do it

An allocation is only meaningful if you maintain it. If you decide on ten per cent and gold then doubles while your equities are flat, you are now holding closer to eighteen per cent and running a materially different portfolio to the one you designed. Rebalancing means selling some of what went up and buying what did not, which is emotionally difficult in exactly the moments it matters most.

Physical metal makes this harder than paper exposure, because the spread between what a dealer will pay you and what they will sell for is real money. Many physical holders therefore rebalance with new contributions instead — directing fresh savings towards whatever is underweight rather than selling anything. It is slower but it avoids the spread entirely.

Knowing your real allocation

You cannot manage an allocation you cannot measure. Plenty of stackers genuinely do not know whether their metal is six per cent of their net worth or twenty-six, because the coins are in a safe, the value moves daily and nobody adds it up.

That is the specific gap a portfolio tracker fills. BullionTally values every item you hold against live spot prices, so the total is current rather than a figure you last calculated two years ago. Once you can see the number, deciding whether it is the right number becomes a much easier conversation to have with yourself.

A note on what this is not

Nothing here is financial advice, and BullionTally does not provide any. Your circumstances, tax position, time horizon and risk tolerance are yours alone, and a general article cannot account for them. What a tracker can do is make sure that whatever you decide, you are deciding it with accurate numbers rather than a rough guess.
