The Inflation King:
Everything you need to know about modern investing can be summed up in the story of one man: Hugo Stinnes, a German industrialist who built the largest private empire in Weimar-era Germany by doing something most people thought was reckless.
He borrowed. Constantly. Aggressively. In marks.
Stinnes came from a coal family in the Ruhr Valley and already ran a solid industrial operation before World War One. When the war ended and Germany began printing marks to pay its reparations debts under the Treaty of Versailles, most citizens watched their savings dissolve in real time. Stinnes drew the opposite conclusion than his neighbors. While German citizens hoarded paper marks in mattresses and savings accounts, Stinnes borrowed enormous quantities of those same marks from German banks, then immediately converted them into real assets: coal mines, steel plants, newspapers, shipping lines, hotels, forests, paper mills. By 1923 his conglomerate, the Stinnes-Konzern, controlled over 1,500 enterprises across Germany, Austria, and beyond. He employed roughly 600,000 people. The inflation that ruined an entire generation of German savers made Hugo Stinnes almost incomprehensibly wealthy.
How did he do it? When a government or central bank expands the money supply, the purchasing power of each existing unit of currency falls. Prices across the economy do not adjust simultaneously. The new money flows into specific assets first, before it filters through to wages and consumer goods, which means whoever holds those assets during the transition captures a windfall. Stinnes borrowed in a currency he correctly identified as dying, bought hard assets whose value was tied to physical reality rather than government decree, and then repaid his loans in marks worth a fraction of what he had borrowed. After the Weimar hyperinflation, the real value of what he owed was virtually nothing. He got the hard assets he bought with loaned marks for free.
Your house today runs the same play, just in slow motion. You take out a mortgage denominated in dollars, a currency the Federal Reserve has expanded by over 40 percent since early 2020. You hold a fixed-rate liability in a debasing currency while the asset itself reprices upward. The bank receives dollars of diminished purchasing power over thirty years. You hold the land and the structure.
The reason property specifically has captured so much of the post-2020 inflation is that new money always travels along the path of least resistance toward collateral-eligible, financeable assets. Residential real estate sits at the center of the credit system. Banks lend against it readily. Institutional buyers treat it as a store of value. When the Fed slashed rates to near zero, and Congress distributed trillions in fiscal transfers, that purchasing power flowed directly into housing markets with predictable results: U.S. median home prices rose from $329,000 in early 2020 to over $420,000 by 2026.
Stinnes died in 1924, before his empire unraveled under poor succession and deflation, but the strategy outlived him. Borrow in the currency they are destroying; hold the asset they cannot print.
