Currency Collapse Cycle

The claim

"Pretty much on average the currency collapses every 30 to 40 years in most political jurisdictions for all of human history," argues Michael Saylor, drawing on historical accounts of currency collapse in sixteenth-century Russia, Rome, and medieval Europe, alongside modern cases within living memory: Argentina's peso, which collapsed against the dollar five times over a century and reached 1,000 pesos to the dollar; Germany's two twentieth-century hyperinflations; Brazil; and Russia.¹

Even the strongest single-currency success story of the twentieth century loses on this measure. The dollar won every major war of the century, became the global reserve currency, and still functions a hundred years later, yet a Miami Beach house worth 100,000 dollars in 1930 is worth roughly 100,000,000 dollars today, a 99.9 percent collapse in purchasing power achieved by the winning currency. That works out to roughly 7 percent annual inflation compounded, far above the approximately 2 percent headline inflation figure typically reported.

Gold's limits, and Bitcoin's pitch

Gold is often proposed as the hedge against this cycle, but the underlying mechanics are imperfect: gold miners add roughly 2 percent new supply annually, which gives gold a purchasing-power half-life of about 36 years, so three halvings over a century would still leave roughly 12.5 percent of original purchasing power.¹ Gold held its value reasonably well during the gold-standard era mainly because the broader economy also grew at roughly 2 percent a year, so dilution and productivity growth approximately offset each other; in a high-growth technology sector a gold standard would produce sharp price deflation, which is part of why gold standards break down under rapid industrial change.

Saylor's framing places Bitcoin as the engineering answer to the same problem gold addresses imperfectly: fixed supply capped at 21 million coins with no dilution of existing holders after the cap, no sovereign control over issuance, no physical vault that can be seized, and an incorruptible ledger that does not depend on any single institution.¹

Dalio's complementary data point

Ray Dalio supplies an adjacent empirical anchor: "Since 1750, 80% of the world's money has disappeared, and all of those that existed have been greatly devalued."² Where Saylor's framing measures how often surviving currencies still collapse, Dalio's measures how many currencies fail outright. Together the two statistics describe a full distribution: currencies either die completely, roughly 80 percent of those that existed since 1750, or survive but debase massively, the remaining 20 percent, which includes the dollar.

Dalio adds a further scenario worth holding alongside the base case: stagflation, when all major currencies devalue together, as happened through the 1970s after the United States ended dollar-gold convertibility. In that regime even diversification across multiple currencies offers no protection, since the devaluation is global and simultaneous, and only assets sitting outside the fiat system entirely preserve value. The asset Dalio names is gold. Bitcoin has a claim to the same shelf, but that extension is this catalog's, not a position he takes; he does not raise it.

The lived version

Two founders in this catalog learned the cycle before they ever read about it, and the reader is directed to their files for what that knowledge does to a career. Wences Casares watched his family in Argentina lose their entire savings three times, first to a devaluation, then to hyperinflation, and finally when the government confiscated bank deposits outright; that history, rather than the cryptography, is the argument he has made for Bitcoin ever since.³ His Lemon Bank co-founder Micky Malka grew up through Venezuela's hyperinflation and devaluation, and says he had to learn the same lesson a second time with his own money on the table, when the bank nearly failed and nearly took every dollar he had ever made with it, "because the economy didn't take off no matter what we did, which is how you learn that macro matters."⁴

The two cases sharpen the pattern in a way the aggregate statistics cannot. A collapse is not experienced as a chart, it is experienced as a household discovering its savings are gone, and both men went on to build financial companies in the regions where it happened, on the premise that a monetary system is contingent rather than permanent.

Why it matters

A person with a seventy-year adult financial life will likely live through roughly two full currency collapses in their primary jurisdiction on this cycle. The practical question the pattern raises is not whether a given currency will eventually debase, since on this evidence it will, but where value gets stored in the meantime, and for how long that store can be held without leaking value through reinvestment risk, maturity, or counterparty failure.
