The Cantillon effect
Why new money makes some richer and others poorer
Cantillon's insight is the answer to a question most people have never asked but should: when the central bank "prints money," who actually gets it? The answer determines the entire distributional politics of monetary policy. Run the simulation below to see the cascade in action.
Why this matters more than most people realize
The textbook treatment of inflation says: more money → all prices rise proportionally → no real effect except wiping out cash holders. This is wrong in a way that matters enormously. New money has a path. The path produces winners and losers determined by where you sit relative to the path.
In the modern US economy, the path runs:
Fed → Primary Dealers → Asset Markets → Asset Holders → Consumer Markets → Wage Earners.
By the time new money has worked its way through the cascade and raised consumer prices, the asset holders have already captured most of the gains. The wage earners are now paying higher prices in dollars whose purchasing power has been diluted to subsidize asset holders' wealth gains. This is not a bug. It's the operating mechanism of post-2008 monetary policy.
Real-world receipts
S&P 500 from March 2009 to early 2022: +600%. This corresponds almost exactly to the period of cumulative QE.
Real (inflation-adjusted) median household income from 2009 to 2024: roughly +12%, mostly in the post-2018 wage gains and 2021 stimulus, then partially eroded by 2022-2023 inflation.
Real median home price in the US from 2012 to 2024: +60%. The bottom 50% of households went from being able to buy a home with median income at 2012 prices to being priced out entirely by 2024.
Top 0.1% wealth share: went from 7% in 1980 to 18% by 2022. The top 0.1% now owns roughly the same share as the bottom 90% combined.
None of these are inevitable forces of nature. They are direct, predictable, mechanical results of how new money enters an economy and which asset class absorbs it first. If new money entered the economy via direct payments to households (as briefly happened in 2020-2021 stimulus), the distributional cascade would run in reverse — consumer demand rises first, asset prices last, wage earners benefit before asset holders.
The argument over how much this matters
Defenders of the current system (Bernanke, Yellen, Powell) argue: financial collapse would have been worse for everyone. Asset prices needed to recover for the wealth effect to lift the broader economy out of recession. Yes, the gains were uneven, but the alternative was a depression that hurt everyone.
Critics (Stiglitz, Selgin, post-Keynesians, Austrians) argue: there were always alternatives — direct fiscal transfers to households, public investment, mortgage relief — that would have worked without the regressive distribution. The choice of monetary policy as the primary tool was political, not technical, and the political choice favored those who own assets. Neither side is fully right, but the critics have the better empirical case for the distributional argument.
What you just learned
Inflation is not a uniform tax. It is a series of specific transfers between specific groups, in a specific order, determined by where the new money enters the economy. Knowing the cascade lets you predict who wins and who loses every time the central bank acts. It also lets you evaluate alternative monetary mechanisms (direct transfers, public banking, debt jubilee) on their distributional merits, not just their headline aggregate effects.
