GDP in Bitcoin and Gold: The Fiat Illusion Behind Economic Growth

Measured in US dollars, the combined GDP of the 38 OECD countries rose from $45.6 trillion in 2010 to $72.8 trillion in 2025: growth of 59%. Measured in gold, the same output shrank 43%. Measured in bitcoin, it collapsed by 99.6% in ten years and 85% in five. Over the last decade, not a single OECD economy grew when its output is priced in gold.

The growth in the headlines is real output plus a shrinking unit of account. Strip out the shrinking unit by measuring in money no one can print, and most of the “growth” disappears. That is the fiat illusion, and this article puts numbers on it for every OECD member over 15, 10 and 5 years.

How we measured it

Gross domestic product is the money value of everything an economy produces in a year. That value is only as steady as the money it is counted in. So we took each country's GDP and counted it in three yardsticks:

• US dollars. GDP in current US dollars for each of the 38 OECD members, from the IMF, World Economic Outlook (October 2026). 2025 values are partly IMF estimates where national accounts are not yet final.
• Gold. Each year's dollar GDP divided by that year's average gold price, from the World Bank Commodity Price Data (the Pink Sheet): $1,225 an ounce in 2010, $1,161 in 2015, $1,770 in 2020 and $3,442 in 2025.
• Bitcoin. Each year's dollar GDP divided by that year's average bitcoin price, from Coin Metrics community data. (Coin Metrics' prices start on 18 July 2010, so the 2010 average covers the second half of that year.)

GDP is a flow across a whole year, so we divide by each year's average price, not the price on one lucky or unlucky day. We also show the official “real” growth rate, the number governments publish after adjusting for their own measure of inflation, so you can see how much of the dollar growth was prices rather than output.

The fiat illusion, in one country

Take the United States. Its GDP rose 105% in dollars between 2010 and 2025. The government's own inflation-adjusted figure, real GDP, rose 43%. The difference is prices: by the official measure, the price level of everything the US produces rose about 44% over those 15 years. More than half of the headline growth was the dollar losing value.

Now measure the same output in gold, a money that cannot be created by a central bank. American GDP in 2025 bought 27% less gold than American GDP in 2010. The economy is larger in dollars, larger in the official real measure, and smaller in the oldest money there is.

None of this means American factories made fewer things. It means the money people are paid in, save in and are measured in has been losing value faster than the economy has been growing. The worker sees a bigger number on the payslip and a smaller amount of real money behind it.

Every OECD economy, measured in gold

Over the last ten years the OECD as a whole grew 52% in dollars and 21% by the official real measure. In gold it shrank 49%. Not one of the 38 members grew. Use the switch to see the 15- and 5-year windows.

Over 15 years, one member, Ireland, grew in gold (+9.2%). Ireland's GDP is famously inflated by multinationals booking intellectual property and profits there, which is why its own statistics office publishes a separate measure that strips those effects out (CSO, modified GNI). Over five years, the one riser is Türkiye (+13%): its dollar GDP rose 119% while its own official real growth was 33%, so most of that rise is the lira's exchange rate and prices, not output. At the other end, Japan's output fell 73% in gold over 15 years; its dollar GDP fell 23% while real output rose 12%, as the yen weakened.

The exceptions prove the rule. Where a country grew in gold, the reason was a statistical quirk or an exchange rate, not a sound money.

What it means per person

Aggregates hide people, so here is output per person, the average share of the economy's production, in ounces of gold. In 2010 the average American's share was worth 39.7 ounces. In 2025 it was worth 26.2, even though in dollars it rose from $48,586 to $90,267.

The same pattern holds across the site's readers: the United Kingdom fell from 32.5 ounces to 16.8, New Zealand from 27.3 to 14.2, Australia from 46.3 to 19.3, Canada from 38.9 to 16.2. Every one of those countries reported growth in its own currency over the period.

Measured in bitcoin

In bitcoin the picture is starker. The OECD's output in 2015 was worth about 175 billion bitcoin. By 2020 it was worth 5 billion. In 2025 it was worth about 716 million: a fall of 99.6% in ten years and 85% in five. Only 21,000,000 bitcoin will ever exist, so a year's output of the richest economies on earth is now worth about 34 times the entire supply.

Over 15 years the bitcoin figure is so large it stops being useful: in 2010 bitcoin was an experiment, priced in fractions of a dollar, and the OECD's output was worth more bitcoin than will ever exist many millions of times over. It is better to read the bitcoin numbers for what they are: the record of a new money being adopted. A fixed supply meeting rising demand means each coin buys more over time, so anything priced in bitcoin, an economy's output or a basket of groceries, falls.

That is the point. One bitcoin is always one bitcoin. Measured in it, life has been getting cheaper. Here is the same thing at kitchen-table scale, from the site's own cost-of-living data:

Gold has its own story, and it points the same way

Part of gold's rise is demand from central banks themselves. The World Gold Council reports that they bought more than 1,000 tonnes in each of 2022, 2023 and 2024, against an average of 473 tonnes a year in 2010–2021 (World Gold Council). The National Bank of Poland, an OECD member, was the largest buyer in 2024. Gold rising is not only fiat currency falling.

But look at who is buying. The institutions that issue fiat currency are adding to a reserve that no one can print, at more than twice their 2010–2021 pace. They are telling you what they think of the yardstick everyone else is paid in. Measured in tonnes, the OECD's yearly output fell from about 1.16 million tonnes of gold in 2010 to about 658,000 in 2025. (For scale: all the gold ever mined comes to about 220,000 tonnes.)

Growth that is real: productivity, not printing

An economy grows in a way that matters when people make more with less: more output per hour, better tools, cheaper energy, smarter processes. In a sound money, that shows up the way it should: prices fall, and the same wage buys more each year.

Fiat currency hides this. When a central bank creates money, the new money reaches the financial system first and pushes up the price of assets, shares and houses, before it reaches wages (the Cantillon effect). Saving in cash becomes a losing strategy, so people are pushed into speculating: buying shares priced on revenue years in the future, leveraging into houses, chasing whatever is rising, because standing still means falling behind. Capital flows to whatever looks like it will outrun the currency, not to what is most productive.

Sound money reverses that incentive. When your savings grow in purchasing power simply by holding them, you do not need to gamble to keep up. A business has to earn its capital by being useful, not by riding cheap credit. That is the time preference argument: hard money rewards patience, and patience builds capital.

Why falling prices suit an AI and automation economy

Artificial intelligence and automation are, at heart, productivity machines. They let the same work be done with fewer hours, fewer errors and less energy. In a free market, that should make goods and services steadily cheaper. Technology has always worked this way wherever it was left to: computing, storage, communication and anything else that rides on them have fallen in price for decades.

Fiat monetary policy is built to stop that showing up across the economy. The Federal Reserve targets inflation of 2 percent a year over the longer run (Federal Reserve), and most other central banks run a similar target. When technology pushes prices down, the target means new money is created to push them back up. The gains of productivity are absorbed by the currency, and the first receivers of that new money keep the difference.

Economists have argued for the alternative for decades. George Selgin's Less Than Zero (Institute of Economic Affairs, 1997) makes the case that prices should be allowed to fall as productivity rises, and Jeff Booth's The Price of Tomorrow (2020) argues that technology is inherently deflationary and that fighting it with ever more debt and money creation is a losing battle. A money with a fixed supply does not fight it. As AI drives the cost of making things down, prices in that money fall, and the gains go to everyone who holds it and everyone who is paid in it, not to whoever is closest to the money printer.

That is the path to abundance: rising productivity, falling prices, and a money that lets ordinary people keep the difference. Falling prices of this kind are not the depression-era spiral people are warned about; they are what progress looks like when the money stays honest (is deflation bad?).

What it means for people who live and work on bitcoin

• Your pay keeps its value. A salary in a money with a fixed supply is not quietly cut each year by inflation. Productivity gains reach you as lower prices.
• Saving works again. You do not need to become a part-time stock picker or property speculator to protect what you earned.
• Spending gets easier, not harder. A falling price level means that what you need tomorrow will cost less, so you buy what you need and save the rest, instead of rushing to spend before the money loses value.
• Businesses compete on usefulness. Without cheap credit to inflate valuations, capital goes to companies that produce something people want, at a price they will pay.

The numbers in this article are history, not a forecast, and short windows can go the other way. But over the ten years to 2025, every OECD economy's output bought less gold and far less bitcoin. The fiat illusion is that we are all getting richer at the rate the headlines say. Measured in money that cannot be printed, we are not, and the gap is the value inflation has taken from the people doing the work.

Questions people ask

Does this mean the economy did not grow?

No. By the official measure, real output across the OECD rose 32% between 2010 and 2025. What fell is the value of that output measured in money that cannot be printed. The gap between the dollar figure (+59%) and the gold figure (−43%) is the fiat illusion: growth that exists only because the measuring stick shrank.

Why measure in gold and bitcoin?

Because neither can be created by a government or a central bank. Gold's above-ground stock grows slowly, by about 1.7% a year from mining, and bitcoin's supply is fixed by its protocol. A yardstick that cannot be stretched shows how much of measured growth is the stick itself changing.

Why use yearly averages?

GDP is everything produced across a year, so it is divided by the average price over that year. Using a single day would make the result depend on the day chosen.

Where can I check the numbers?

Every figure is computed from three public sources: the IMF World Economic Outlook, the World Bank Pink Sheet and Coin Metrics. Each chart has a “The numbers” table with every value.
