Your boss got a raise. Their stocks went up. Their house went up. Your rent went up too β but your wage didn't quite keep up. You felt poorer at the end of every month even though the official inflation rate looked manageable.
That feeling has a name. An 18th-century banker named it about 300 years ago, and the dynamic he described is the most important thing nobody taught you about how money actually works.
Richard Cantillon was an Irish-French banker who lived from roughly 1680 to 1734. He made a fortune speculating during the Mississippi Bubble and the South Sea Bubble β the two most famous financial manias of his century. After cashing out, he wrote a single book: Essai sur la nature du commerce en gΓ©nΓ©ral ("Essay on the Nature of Commerce in General"), published posthumously in 1755 [1].
One observation in that book has echoed through three centuries of monetary economics: new money does not enter the economy uniformly. It enters at specific points, flows through specific channels, and benefits the people closest to those channels disproportionately. The further you are from where the new money enters, the worse you do. Modern economists call this the Cantillon Effect.
Imagine the Federal Reserve creates one trillion new dollars tomorrow. Where do those dollars go?
Not into your checking account. The Fed buys Treasury bonds from a small list of "primary dealer" banks β Goldman Sachs, JPMorgan, Citi, and a dozen others [2]. The banks now have new reserves and lower yields on safe assets. To find returns, they extend credit to the next ring out: hedge funds, private equity, REITs, large corporations buying back stock.
Those institutions buy assets β equities, real estate, fine art, private companies. Asset prices rise. The wealthy, who own most of the assets, get wealthier. Their portfolios are now worth more. The trillion dollars hasn't yet shown up in consumer prices because it hasn't yet reached consumer wallets.
Eventually, slowly, that wealth leaks into the rest of the economy. Asset owners spend a portion of their gains. Companies hire. Wages rise β but they rise after consumer prices have already risen. By the time you get a 4% raise, your rent is up 8%, your groceries 12%. You are mathematically further behind, even though you "got more money."
The Cantillon Effect is not a glitch in the system. It is the predictable, structural output of a monetary system where new money enters via the asset-owning class first.
The COVID stimulus era was a textbook Cantillon experiment, run in real time on the entire U.S. economy.
Between February 2020 and April 2022, the Federal Reserve grew M2 (broad money supply) from roughly $15.4 trillion to $21.7 trillion [3]. That's a ~$6.3 trillion expansion in 26 months β about 41% growth, the fastest peacetime monetary expansion in U.S. history.
Where did that money go first?
Where did it arrive last?
If you owned stocks and a house in 2020, the Fed's response made you significantly wealthier in dollar terms. If you were a 22-year-old renting and saving cash, the same response made you measurably poorer. The wealth gap widened not because the wealthy worked harder, but because the monetary plumbing put new money in their hands first.
The Cantillon Effect isn't a left-right issue. Both parties run deficits and both nominate Federal Reserve chairs who expand the money supply when it's politically convenient. The mechanism survives elections because it benefits whoever already has assets β and the people with the most political influence already have assets.
A wage earner is told that monetary expansion is "stimulus" or "supporting the economy." What it actually does is dilute their savings while inflating the assets they don't own. They feel poorer. They are told the inflation isn't real, or it's transitory, or it's the previous administration's fault. They are told to ask for a raise.
None of that addresses the underlying mechanism. The monetary system itself is the cause, and a system can't fix itself.
The only escape from Cantillon dynamics is to hold an asset whose supply cannot be expanded. Real estate is partly Cantillon-resistant β there's a fixed amount of Manhattan. Gold is partly resistant β the annual mining inflation is roughly 1.5% of stock. Stocks are not β companies issue new shares all the time, and the ones that don't hold cash get diluted by everyone else's monetary expansion.
Bitcoin is the first asset in human history with a perfectly rigid supply cap. Twenty-one million coins. Enforced by code, validated by every node on the network, unchangeable by any central authority. There is no Cantillon first-in-line for Bitcoin issuance because there is no issuance authority. The 22-year-old in 2026 can acquire Bitcoin on the same terms as BlackRock can β there is no minimum, no accredited-investor wall, no political relationship required.
That doesn't mean Bitcoin's price won't move. It will move violently. But the supply curve is fixed, which means that over a long enough timeframe, monetary expansion in fiat translates into price appreciation in Bitcoin. Holding Bitcoin doesn't make you immune to inflation β it makes you a participant in the inflation rather than its victim.
The Cantillon Effect is what happens when you hold the diluted asset. Bitcoin is a bet on holding the un-dilutable one.
You don't have to believe Bitcoin will be the future of money to take the Cantillon Effect seriously. You just have to believe that the U.S. government will keep deficit-spending, the Fed will keep monetizing the resulting Treasury issuance, and the people who own scarce assets will keep getting wealthier than the people who don't.
The first part is mathematical: the Treasury issued over $2 trillion in net new debt in 2024 alone. The second is institutional: the Fed has bought Treasuries during every recession of the past century. The third is structural: the U.S. wealth gap has widened in every decade since 1971, when the dollar's last link to gold was severed.
You can vote, complain, organize, and hope the system reforms. Or you can opt out of the diluted asset and hold the un-dilutable one. Most likely both. But pretending the dynamic doesn't exist is the option that costs you the most.
