Ray Dalio says the U.S. just had its ‘Suez moment’—and history says what comes next could end an empire

He wrote it about the United States in March 2026. But the parallel he was drawing was unmistakable — and deliberate. The Bridgewater Associates founder and Fortune contributor, who has spent decades mapping the rise and fall of reserve-currency empires over 500 years of history, traced back to a single afternoon in November 1956 to explain what he believed was happening in real time to the most powerful country on earth. That afternoon, British Prime Minister Anthony Eden received a phone call that ended an empire.

Within four years of the Suez Crisis, Britain had granted independence to Ghana, Mala
