Who Actually Benefits From New Money? (The Cantillon Effect)

Between the March 2009 low and the end of 2024, the S&P 500 rose more than eightfold. Home prices in most major U.S. metros roughly doubled. The Federal Reserve's balance sheet grew from about $900 billion before the 2008 crisis to nearly $9 trillion at its 2022 peak — a tenfold expansion in a decade and a half.

Over the same window, median real wages crept up by a small single-digit percentage. Rent kept rising. A dozen eggs, a gallon of gasoline, a pound of ground beef — all visibly more expensive than they used to be.

If you owned financial assets in 2009, that fifteen-year window made you dramatically wealthier. If you didn't — if your stake in the economy was a paycheck and a checking account — you watched the cost of everything rise while your wages barely kept up.

That gap is not an accident. It's not the result of any single policy decision, and it isn't a conspiracy. It's the structural consequence of how new money enters the economy, and it has a name: the Cantillon effect. The mechanism was described in 1730 and hasn't changed much since. Only the channels have.

The mechanism, in one sentence

New money doesn't land in everyone's account at the same time. It enters the economy at specific points and ripples outward from there. The people and institutions that receive it first can spend it before prices adjust. The people who receive it last pay the higher prices without any of the new money.

That gap between the early receivers and the late receivers is the Cantillon effect. It's a wealth transfer, and it's structural, not political. Whoever holds the new money while prices are still catching up gets to trade it for real goods at the old prices. Whoever gets only the higher prices and not the new money loses purchasing power with no offset.

The mechanism says nothing about whether monetary expansion is good or bad policy. It just says the gains and losses aren't distributed evenly, and where you sit in the chain determines which side you end up on.

The original story

The idea is named after Richard Cantillon, an Irish-French banker writing in the early 1700s. His Essai sur la Nature du Commerce en Général was written around 1730 and published posthumously in 1755. It's one of the foundational texts of modern economics, and it contains a passage that remains surprisingly fresh.

Cantillon was watching Spanish galleons bring New World gold into Europe. The gold entered the continent through a specific door — the Spanish royal treasury — and he noticed that the order in which it reached people mattered enormously.

It arrived first in Madrid. The king spent it on soldiers, supplies, court luxuries, and foreign imports. The merchants who supplied the court got rich. Their suppliers did a little better. Workers in the merchant economy saw slowly rising wages. And the peasants in the countryside, far from any of this, saw only the eventual result: higher bread prices, higher land rents, higher taxes, and no new income to match.

The early receivers — the king, the courtiers, the merchants supplying them — got to spend the new gold before prices had adjusted. By the time the money reached the peasants, the prices had already risen. The peasants got the inflation without any of the money. The merchants got both. The king got the gold first.

Cantillon put it plainly enough: new money doesn't affect prices at the moment it is created — only as it is spent. The first spender trades the new money at the old prices. Every subsequent holder gets a slightly worse deal. The last people to see the money see only the prices.

Where new money actually enters today

The Spanish royal treasury is gone, but the structure isn't. New money today enters the economy through a small number of specific channels, and the people connected to those channels are the first to benefit.

Open market operations. The Federal Reserve buys U.S. Treasury securities from a select list of primary dealers — about two dozen large banks and broker-dealers authorized to trade directly with the Fed. When the Fed buys, it pays by crediting the dealers' accounts at the Fed itself. Those credits — called reserves — are new money, created on the Fed's ledger. The dealers use them to buy other assets. The new money enters through the largest financial institutions first.

Quantitative easing. Same mechanism, much larger scale. During the 2008 crisis and again in 2020, the Fed bought trillions of dollars of Treasuries and mortgage-backed securities (bonds backed by pools of home loans) directly. Bank reserves expanded dramatically. Asset prices rose because the people buying assets — banks, funds, and anyone connected to the financial system — had more money to bid with. The FRED series WALCL shows the Fed's balance sheet through these periods: the tenfold expansion didn't land in checking accounts. It landed in institutional portfolios.

Commercial bank lending. As the previous article in this series walked through, most new money is created by banks making loans. A mortgage doesn't move existing dollars from one account to another; it creates a new deposit at the moment of approval. That new money enters the economy at the borrower — which in practice means people with collateral, credit history, and the ability to qualify. People who can't borrow don't receive any of the newly-created money directly. They face the prices bid up by everyone who did.

Government spending on deficit. When the federal government spends more than it takes in and the Fed ultimately backstops the borrowing, the new money flows first to whoever the government pays: defense contractors, infrastructure firms, social program recipients, bondholders, federal employees. The money circulates outward from those first recipients.

In every case, the last people to see the money are people who don't own financial assets, can't borrow, and don't contract directly with the government. The prices they face are set by everyone who got there first.

What the data shows

If the Cantillon effect were purely theoretical, this would be a philosophy article. It isn't. The data since 2008 is consistent with the mechanism in specific, measurable ways.

The post-2008 era has produced the most sustained central-bank balance-sheet expansion in modern history. Over that window:

• Asset prices grew sharply. The S&P 500 rose more than eightfold from its March 2009 low through the end of 2024. Home prices in most major metros roughly doubled. These are the markets where new money lands first.
• Real wages barely moved. The median real wage grew by a small single-digit percentage over the same window. This is where the money lands last.
• Wealth concentrated. The Federal Reserve's Distributional Financial Accounts show that the top 10% of U.S. households own the vast majority of U.S. corporate equity — counting both direct holdings and shares held through mutual funds and retirement accounts. When stocks go up, most of the gain goes to those households. When wages stagnate, everyone else pays the bill.

The Federal Reserve's own research has acknowledged the dynamic. A 2021 FEDS Note from the Fed's Division of Research and Statistics walked through how monetary policy can widen wealth inequality through asset-price channels. The paper's framing is careful: it treats distributional effects as a policy trade-off rather than a failure. But the mechanism the Fed is describing is the Cantillon effect.

Why this isn't talked about more often

A reasonable objection at this point: if the Cantillon effect is real and the Fed itself acknowledges the dynamic, why isn't it a bigger part of mainstream inflation discussions?

The answer is that economists disagree about significance, not existence. The mechanism is uncontroversial as economic theory. Almost every monetary economist accepts that new money enters through specific channels and that the early recipients have an advantage. The disagreement is about how large the distributional effect is relative to other forces, whether it should change monetary policy, and whether fiscal policy is the right tool to address it.

Central banks aren't designing policy to enrich asset holders. They operate through the financial system because that's how the plumbing works. The Fed can't deposit new reserves into your checking account; the only accounts it can credit are the ones banks hold at the Fed itself. The Fed's job, as it sees itself, is to manage aggregate demand and price stability. The distributional side effect is real, but it isn't the lever the Fed is trying to pull.

None of that makes the effect smaller. It just means the people on the receiving end of the higher prices rarely hear the mechanism named. The gains are diffuse and statistical; the losses show up in grocery bills. Grocery bills don't come with a footnote explaining where the money went first.

The Bitcoin angle

The reason this article lives on a site about Bitcoin is specific. A Cantillon effect exists only if there's a privileged early receiver of new money. Remove that, and the mechanism can't operate.

Bitcoin's issuance schedule was fixed in the 2009 genesis block and hasn't changed since. New bitcoins enter circulation through mining, under rules anyone can follow. There is no primary dealer desk for Bitcoin. There is no central authority deciding which institutions receive the next round of supply. The halving schedule cuts miner rewards in half roughly every four years. It runs on its own clock, regardless of who owns bitcoin.

That doesn't make Bitcoin morally cleaner, and it doesn't mean early Bitcoin adopters didn't benefit from getting in early. They clearly did. The relevant claim is narrower: the monetary system itself doesn't contain a Cantillon mechanism. The schedule is the schedule. The protocol applies the same rules to everyone — there's no class of insider who gets coins on better terms.

That's a real structural difference from the dollar, where the system is built with first-receivers in mind. Whether a Cantillon-free monetary system works better or worse than one with banks and central authorities standing in the middle is a harder question. Whether the two are structurally different is not.

What the clock measures

Every price on Satoshi's Clock — from a month of rent to a cup of coffee, from a dozen eggs to a gallon of gasoline — is a price that moved because new dollars entered the system somewhere upstream. The people who saw those prices rise without a matching raise are the late receivers of the mechanism this article is about.

The clock measures the late receiver's experience. It counts the years it would take, under a given Bitcoin growth scenario, for a satoshi to buy one dollar of today's purchasing power. Every item in the basket is a version of the same question: how long does it take for the currency at the end of the chain — the one the peasants got stuck with in Cantillon's original story, the one wage earners and savers hold today — to finish losing its value against a supply that's fixed?

The answer depends on the scenario you believe in. The mechanism driving it is the one Cantillon described almost three hundred years ago. The only thing that's changed is the channel.
