Money you can't print.
Hard money is money whose supply is costly to expand. Gold is the classic benchmark. This page covers what makes money hard and where gold falls short, how the world left gold in 1971, and what that did to the purchasing power of a dollar.
What makes money hard
Hardness is about how difficult it is to make more. Everything else on this list is what lets a scarce thing actually work as money. Each property gets an honest rating for gold, weak spots included.
Scarcity
Gold: strong
Mines added about 3,300 t in 2025 [usgs] to roughly 222,600 t above ground [wgc], about 1.5% a year (our calculation). Higher prices encourage mining, but new mines take years to open.
Durability
Gold: strong
The World Gold Council calls gold "virtually indestructible", so almost all gold ever mined still exists [wgc].
Divisibility
Gold: mixed
It can be recast in any size, but very small pieces are hard to handle and carry higher premiums per gram. That is one reason people used silver and paper claims for everyday purchases.
Portability
Gold: weak spot
Lots of value in little weight, but large amounts are heavy, costly to insure and slow to ship. That pushed people toward paper claims, which meant trusting whoever held the metal.
Fungibility
Gold: strong, with a caveat
Gold is an element, so a pure ounce is the same anywhere. Bars and coins vary in purity and form, so the market relies on refiner standards such as LBMA Good Delivery [lbma].
Verifiability
Gold: good, not effortless
Colour, weight and density make it hard to imitate. Skilled fakes exist, so the market relies on testing, assayers and established dealers.
Store of value
Gold: strong over decades, uneven over years
It has kept purchasing power far better than the US dollar since 1971 (figures below). Its price can still fall or go sideways for years, and it pays no interest.
The scarcity figures mix WGC (stock, end-Q2 2026) and USGS (flow, 2025 est.) data; WGC rounds to the nearest 100 t.
Gold as money: a short history
- Some of the earliest known coins are struck in Lydia [lydia].
- Britain puts its currency on gold by law [1816]; many major economies follow by about 1880 [bordo].
- The US Gold Standard Act of 1900 makes gold the standard of value at the dollar's existing gold weight, about $20.67 an ounce [gsa][gra].
- Executive Order 6102 requires Americans to deliver gold coin, bullion and gold certificates to a Federal Reserve Bank, branch or agency, or a member bank, by 1 May 1933, with a $100 exemption [eo].
- The Gold Reserve Act sets gold at $35 an ounce, cutting the dollar's gold value to 59% of its 1900 level [gra].
- At Bretton Woods, 44 nations agree a system pegging currencies to the dollar and the dollar to gold at $35 an ounce [bw].
- Eight central banks run the London Gold Pool to defend $35; it collapses in March 1968 [frbend].
- Nixon: "I have directed Secretary Connally to suspend temporarily the convertibility of the dollar into gold or other reserve assets…" [nixon] The Smithsonian agreement followed, and the Bretton Woods system ended soon after [frbend].
- Americans may legally own gold again [gra].
- Canada finishes selling its official gold reserves [fin16].
- Central banks hold about 39,000 t, 18% of all above-ground gold [wgc], and with other institutions bought 288.9 t in Q2, up 62% year on year [gdt].
The pattern across these dates is the same: while money was tied to a fixed weight of gold, creating more of it was constrained by the promise to redeem it in gold. Each break, in 1933, 1934 and 1971, loosened that limit. The 1971 suspension was announced as temporary [nixon], and the system it suspended ended soon after [frbend]. That is why the debasement figures below start in 1971.
Where the gold is
Gold is unusual among commodities because almost none of it is used up. Roughly two-thirds of all gold ever mined has been mined since 1950 [wgc], and nearly all of it still exists in some form. About 45% of the above-ground stock is jewellery, which gives gold broad demand outside its role as money [wgc]. Central banks hold about 39,000 t [wgc], and exchange-traded funds about 4,000 t [wgc].
Official buying has been heavy recently. Central banks and other institutions bought a revised 56.5 t in Q1 2026 and 288.9 t in Q2, about 345.4 t in the first half (our calculation) [gdt]. That matters for the hard-money case in one specific way: the institutions that issue fiat money still treat a metal they cannot print as a reserve asset.
Debasement, in two numbers
Using annual averages, the US consumer price index rose from 40.483 in 1971 to 321.962 in 2025 [cpi]: prices up about 8×, so a 1971 dollar buys about 13 cents of goods today. Over a similar span, gold went from the official $35 [frbend] to a US$4,506.29 LBMA PM average for Q2 2026 [gdt], about 129× (our calculation).
The two numbers measure different things. CPI tracks what a basket of goods costs in dollars; the gold price tracks what an ounce costs in dollars. CPI rising shows the dollar buying less; gold rising far faster also means gold itself gained about 16× in real terms (our calculation), which is why the ratio is so sensitive to start and end dates.

Where the critics are right
A fair case has to admit its weak points. Three objections hold up well. Gold pays no yield, so holding it has a real cost when interest rates beat inflation. It is not a practical way to pay for everyday things, so it works as savings rather than as a payment method. And over long periods stocks have returned more, because businesses produce earnings and a bar of metal does not. Five more objections, including volatility, storage cost, confiscation and price manipulation, are partly answered. The objections tracker gives each one with its verdict.
What holding gold involves
A description of the trade-offs, not instructions.
Physical vs paper
Physical metal is nobody's promise to pay; ETFs and certificates are claims on someone. ETFs hold about 4,000 t [wgc].
Costs
Dealer premiums, sell-back spreads, storage, insurance, fund fees and tax all apply, and gold pays no income.
Rules can change
The 1933 order shows that private holdings can be subject to rules owners didn't choose [eo].
Price risk
Gold's price can fall and stay down for years. Any allocation is a personal decision.
