Global oil supply is tightening sharply as the Strait of Hormuz disruption removes a critical share of global crude and refined product flows. The scale of the imbalance is forcing markets to rapidly reprice supply risk, with physical shortages becoming more pronounced. What began as a transport disruption is now evolving into a broader supply constraint across key producing regions. This escalation highlights the growing risk that the shock could persist beyond the near term and reshape global energy flows.
Bruno Santos, Brazil Market Intelligence Analyst at StoneX, has tracked global oil trade flows and supply disruptions across multiple market cycles. His analysis focuses on how logistical constraints evolve into structural supply imbalances, offering insight into the current escalation in global oil markets.
Key Themes from the Discussion
Global oil production fell by around 10 million barrels per day following the Strait of Hormuz disruption.
Only about 25 percent of Persian Gulf exports have been successfully rerouted through alternative routes.
Production losses are now emerging alongside logistical constraints, deepening the supply shock.
Global Oil Supply Losses Expand as Hormuz Disruption Persists
Global oil supply losses are expanding as the Strait of Hormuz disruption continues to restrict flows from the Persian Gulf. Bruno Santos emphasizes the scale of exposure, stating that "the Persian Gulf accounts for roughly 20 to 25% of global oil supply", highlighting the systemic importance of the region. Consequently, even partial disruptions are translating into significant global shortages as alternative routes fail to fully compensate. This imbalance is tightening physical markets and increasing competition for available barrels, driving greater price volatility.
Production Cuts Intensify Global Oil Supply Imbalance
Production cuts are intensifying the global oil supply imbalance as logistical disruptions begin to impact output levels directly. Santos notes that "we had a reduction of around 10 million barrels per day of global production in March", reflecting the scale of the disruption linked to the Persian Gulf. As a result, the supply shock is no longer confined to transportation issues but is becoming embedded in production capacity across key exporters. This shift increases the likelihood of sustained market tightness, with broader implications for refined products, trade flows, and global economic stability.
