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

“Watch out for allies and creditors losing confidence, the loss of its reserve currency status, the selling of its debt assets, and the weakening of its currency, especially relative to gold.”

Ray Dalio didn’t write that sentence about Britain in 1956. 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.

The original Suez moment

In late October 1956, Britain and France — alongside Israel — invaded Egypt after President Gamal Abdel Nasser nationalized the Suez Canal, the vital trade artery connecting Europe to Asia. Militarily, the operation was a success. Within days, Anglo-French forces controlled the northern portion of the canal, but it unraveled off the battlefield.

The United States, alarmed by the unilateral action and unwilling to allow its allies to destabilize the Cold War equilibrium, applied crushing pressure. Washington threatened to withhold emergency IMF loans as the British pound came under speculative attack. It was financial warfare, and it worked. Eden, facing a currency crisis, withdrew from Egypt in humiliation within weeks.

The military had won. The empire had lost. And what followed was a cascade that Dalio, in Bridgewater’s research, describes as the classic sequence of imperial decline: allies stopped deferring to London; creditors reassessed British debt; the pound sterling — which had served as the world’s reserve currency for over a century — began its long retreat. Within four years of the Suez Crisis, Britain had granted independence to Ghana, Malaya, Nigeria, and Cyprus. Within a decade, Harold Macmillan’s “winds of change” speech had formalized what Suez had revealed: the British Empire was in managed retreat, not strategic expansion.

Today, Britain is a prosperous, mid-sized economy of nearly 70 million people, with a GDP that ranks fifth........
