Iran Escalates Tanker Attacks as Hormuz Oil Flows Rise

Iran has intensified its attacks on tankers in the Strait of Hormuz, coinciding with a rise in oil and gas shipments through the critical waterway. UK Maritime Trade Operations reported nine attacks in October alone, nearly matching the total from September. This escalation follows a pattern of fluctuating intensity since the start of the Iran war, with previous strikes briefly disrupting shipments before volumes recovered.

The impact of these attacks on energy flows remains uncertain. Maritime security officials and shipping executives have not yet determined whether the latest attacks will lead to a significant reduction in shipments. The Strait of Hormuz is a key chokepoint for global energy supplies, particularly as winter approaches in the Northern Hemisphere. Recent price increases have raised concerns about sustained inflation and potential interest rate hikes in major economies.

In response to market tensions, several consuming nations announced plans to release emergency stockpiles of oil. US President Donald Trump has also been exploring ways to stabilize domestic fuel prices ahead of midterm elections. Dimitris Maniatis, CEO of risk management firm Marisks, noted that Iran's strategy appears to be creating fear and uncertainty rather than halting every vessel. Most tankers transiting Hormuz are using a corridor near Oman's coast with their digital signals switched off, making it difficult to track supply movements accurately.

The flow of oil through Hormuz has been steadily increasing since summer, with some Wall Street banks reporting shipments nearing pre-war levels. However, liquefied natural gas (LNG) shipments have been more limited due to the specialized nature of the carriers. The latest attacks have also driven freight rates to record highs, with the cost of transporting oil from the Persian Gulf to China reaching US$1.3 million a day on Monday, according to the Baltic Exchange.
