The ongoing conflict in the Middle East, now in its third week with the Strait of Hormuz effectively closed, has become a historic breaking point for the global economy, according to billionaire investor Ray Dalio. The founder of Bridgewater Associates warned that the escalating crisis is not merely a regional war but potentially the beginning of a collapse scenario that could shatter US dominance in the world order. 1956 Suez Crisis parallel In an article published on Substack, Dalio drew a striking historical parallel to Britain's 1956 Suez Crisis, which marked the end of the British Empire. The investor argues that the US is now facing a similar test. According to Dalio, the disruption of trade through the Strait of Hormuz, combined with the potential shift from dollar to yuan for oil transactions, would deliver the heaviest blow to US economic power. Three signals of collapse Referencing his famous "Big Cycle" theory on the rise and fall of empires, Dalio stated that the US is currently in the most dangerous phase of this cycle. He outlined three critical factors that could trigger collapse: Economic Deadlock: The unsustainable massive debt burden of the US economy and the steady erosion of the dollar's purchasing power. Internal Fragility: Deep political polarization and increasing social tensions within the country, leaving the US weak and vulnerable against external threats. Attritional Wars: High-cost conflicts with regional powers like Iran that rapidly deplete both military and economic resources. Petrodollar threat One of the most critical points in Dalio's analysis is the scenario of sidelining the dollar in oil trade. He warned that if Iran or other regional actors require alternatives like the Chinese yuan for energy transfers through the Strait of Hormuz, the decades-old "petrodollar" system could collapse. If this scenario materializes, the dollar would lose its status as the global reserve currency, the US would become unable to finance its debts, and its global power would rapidly evaporate. Investor warning Dalio emphasized that the current world order is seriously "cracking" and that reading the process merely as a geopolitical crisis would be a mistake—it is also an era of massive wealth transfer. The billionaire investor stressed that to survive systemic changes and breakdowns of this magnitude, investors must pivot toward diversified portfolios and real assets as a vital necessity. Conflict context The US and Israel launched joint attacks on Iran on Feb. 28, killing over 1,300 people according to Iranian authorities, including former Supreme Leader Ayatollah Ali Khamenei. Iran has retaliated with strikes targeting Israel and Gulf states while effectively closing the Strait of Hormuz, which normally handles 20 million barrels of oil daily. The conflict has expanded to Lebanon, where over one million have been displaced.
