The 100-Year Curse and the Life Cycle of World Money

It’s 1914 in London.

The British pound is the undisputed king of global trade.

Ships bearing the Union Jack carry goods to every corner of the planet.

City of London bankers boast that the pound’s dominance is eternal.

Within 50 years, it’s gone.

Not the pound itself — but its crown. The U.S. dollar took its place. And the cycle began again.

The Pattern No One Talks About

If you zoom out far enough, you’ll see it.

Every reserve currency in history — the world’s preferred store of value and medium of exchange — has a lifespan of roughly 80–110 years (give or take a few decades).

Here’s the rough timeline:

Currency

Rise to Power

Peak

Decline

Spanish Real

late 1400s

1500s

early 1600s

Dutch Guilder

early 1600s

mid 1600s

early 1700s

French Livre

early 1700s

mid 1700s

late 1700s

British Pound

early 1800s

late 1800s

mid 1900s

U.S. Dollar

1944

1990s–2000s

???

Right now? We’re 81 years in.

Why They All Fall

It’s not magic. It’s math and human behavior.

  1. Dominance Brings Privilege. A strong currency lets you borrow cheaply, run deficits, and fund expansion.

  2. Privilege Breeds Complacency. Empires overextend — militarily, financially, politically.

  3. Competitors Rise. New trade hubs emerge. Alternative payment systems develop. The “captive” audience for your currency starts to shrink.

  4. Debt and Inflation Erode Trust. Once the world doubts your ability to keep promises, the exit doors open.

Where the Dollar Stands

The U.S. dollar became the reserve currency at Bretton Woods in 1944.

It survived Nixon breaking the gold link in 1971. And it peaked in the unipolar moment of the 1990s.

Now?

  • Central banks are buying gold at the fastest pace in 55 years.

  • BRICS nations are building trade settlement systems outside the dollar.

  • U.S. debt is climbing faster than GDP growth.

The movie isn’t over — but we might be in the third act.

What History Teaches Us

If the pattern holds, we don’t need to panic.

We need to prepare.

  • Diversify across assets and geographies.

  • Understand that a reserve currency’s decline is a process, not an event.

  • Watch for inflection points — sudden policy shifts, trade bloc announcements, and large-scale reserve sales.

Because one thing is certain…

The next global reserve currency is already being born.

And you probably won’t recognize it when you first see it.
