Empires do not collapse because they lose a single battle. They fall when they lose control over the systems that connect the world to them. This is not rhetorical language, but a central conclusion presented by global investor and thinker Ray Dalio in his 2021 book The Changing World Order, where he traces the trajectory of empires over five centuries. His analysis identifies a recurring pattern: rise, peak, and gradual internal erosion that ultimately manifests as an inability to secure global trade arteries.
The British Precedent: Suez as a Turning Point
The most illustrative example is the British Empire. Once ruling a quarter of the world, its decline did not occur overnight. The turning point came when Britain lost control of the Suez Canal following the 1956 Suez Crisis.
At that moment, Britain did not merely lose a military confrontation. It lost a strategic lifeline through which its trade and influence flowed. From there, a quiet but decisive decline began, transforming “Great Britain” from the centre of the global order into a diminished state.
The Strait of Hormuz: A Modern Strategic Artery
Today, history appears to be presenting a parallel through a more complex and critical node: the Strait of Hormuz.
This passage is not only responsible for the transit of nearly one fifth of the world’s oil, but it also functions as a layered artery of the modern global economy. Through it pass shipments of vital resources such as helium, essential for advanced industries, and fertilisers that underpin global food security.
Moreover, it forms part of a broader infrastructure network that includes undersea communication cables carrying global internet and data flows. The issue is no longer limited to oil, but extends to the structural foundations of modern life itself.
Dalio’s Warning: A Defining Global Moment
In recent remarks cited across multiple media platforms, Ray Dalio warned that control over the Strait of Hormuz grants immense influence over the global economy. He suggested that conflict surrounding this chokepoint could represent a decisive moment in shaping the next phase of the international order.
Such moments, in his framework, are often associated with systemic transitions, where existing powers face structural challenges that redefine global leadership.
A Test of American Power
Within this context, the Strait of Hormuz becomes more than a geographic location. It emerges as a concentrated historical test.
Just as the Suez Canal exposed Britain’s inability to maintain its imperial position, Hormuz now reflects the United States’ capacity to preserve its global standing. This is particularly significant amid mounting debt, deepening internal divisions, and the rise of China as a competing power reshaping global balances.
Patterns of Decline and Strategic Inflection
According to Dalio’s reading of history, events do not repeat themselves in identical form, but they replicate patterns with striking consistency. The decline of major empires often begins with moments that appear limited in scale but carry deeper structural implications.
Today, the world faces a critical question: could the Strait of Hormuz become the new Suez Canal, marking the beginning of a major geopolitical shift? Or is the current moment even more profound, testing not just a single strategic artery, but the entire system upon which global order has been built?
Beyond Geography: Hormuz as a Symbol of Power
The strategic focus of Washington’s war on Iran has centred heavily on the Strait of Hormuz, despite the fact that US oil flows do not depend on it, as President Trump has repeatedly stated.
This underscores a deeper reality. Hormuz has evolved from a narrow waterway into a symbol of American dominance, authority, and control over global systems.
If control over this chokepoint is lost, the implications extend far beyond the battlefield. It would signal not only a strategic defeat, but a broader weakening of American economic and political power, including pressure on the US dollar.
In that scenario, the loss would not be confined to a single conflict. It would mark the beginning of a larger transformation for an empire that has stood at the centre of the global order since the end of the Second World War.
