Imagine you’re at an auction. Maybe it’s in person, maybe it’s ebay, whatever.
There are 10 people each with 10 dollars/Euros/pesos. There are 10 items for sale.
What’s the maximum price an item will fetch? 10, assuming that no one cooperates/pools their money.
Now, suppose the government announces mid-auction that the 10 dollar bill is now worth 20 dollars.
What’s the maximum price an item can fetch now? Even though the item was worth 10 just moments ago, it can now fetch 20 because buyers now have double the currency.
Even if the total number of items hasn’t changed, prices can double because there’s that much more money in circulation.
When we talk about inflation, we’re often talking about what we see as buyers – the price of a loaf of bread or a cup of coffee. But those are symptoms of inflation. The root cause is how much money exists. In the old days – pre-1971 – in the USA and many other countries, the amount of money that existed was dependent on how much valuable metal you had stockpiled. The more gold and silver you had in vaults, the more money you had because at any time, someone could redeem their printed currency for a chunk of metal.
If you read the little printing on old USA bills, it says something like: “This note is legal tender for all debts, public and private, and is redeemable in lawful money at the United States Treasury or at any Federal Reserve Bank.”
What does it say now? “This note is legal tender for all debts, public and private”. That’s it. It’s not redeemable for anything because it’s no longer rooted in a tangible good.
Today, in a well-run economy, money is worth the equivalent amount of goods its economy produces. If a country produces a trillion dollars of goods and services, and it has a trillion dollars in circulation, it’s in balance.
Every time the government prints more money than there are goods? You end up with the auction example. More money without a commensurate increase in goods and services means that prices go up.
Which brings us to the chart in today’s post. In 2020, at the start of COVID, the US government printed trillions of extra dollars. That leveled off in 2022 through mid 2024, but then resumed in earnest in 2025. In early 2026, the US government has increased its printing of new money – but the underlying economy isn’t producing more goods and services (we know this from employment numbers – the base economy is stagnant).
What this means is that inflation itself is spiking now, which means we’ll see additional price increases in the weeks and months to come as that excess money supply sloshes around the system. We’ll see more risky behavior and questionable investments; the crypto markets would never have flourished as much as they did in 2020-2022 without the 3 trillion extra dollars that investors and banks needed to find a home for.
Whatever you pay for now, expect to pay more soon.
Inflation’s root cause
The root causes of this stagnation should be fairly clear – a mix of rising inflation, technological change (AI), and societal/political changes. Inflation alone accounts for a significant portion of what we’re seeing; the OECD’s measure of monetary supply, M3, shows that the United States has been running the printing presses to all-time highs, creating more money than ever before in its history:
In early 2026, the US government ramped up its money printing significantly over its previous path, possibly to help fund the war it started.
What happens when a government prints money? By printing more money and putting more money in circulation, prices go up. That disruption impacts hiring because it puts upward pressure on salaries, reducing hiring demand. It’s one of the reasons the US Federal Reserve talks about its dual mandate of full employment and low inflation.
