Divergence Between Physical and Futures Oil Prices Signals Severe Global Supply Shock

Since the onset of the US-Israel military campaign against Iran in early 2026, global oil markets have experienced significant volatility, with benchmark prices surpassing $103 per barrel following US President Donald Trump's announcement of a naval blockade. Analysts highlight a critical and widening gap between physical spot prices, such as Dated Brent, and paper futures contracts. This divergence reflects a severe mismatch between market perceptions and the harsh reality of supply constraints caused by Iran's effective closure of the Strait of Hormuz. Maritime data indicates that vessel transits through the strait have plummeted from approximately 130 daily to just 17, creating an estimated daily global shortfall of 8 million barrels. While futures prices indicate future expectations, spot prices reveal the immediate scarcity driving up fuel costs for households worldwide. Despite a fragile ceasefire, the disruption remains one of the largest in history, straining the global economy. The article explains that while alternative routes from countries like Saudi Arabia have been boosted, they are insufficient to offset the loss, leading to an energy shock more serious than initially appreciated by mainstream indicators.
